Sánchez * Remi Collet Peace, A. Jesse Jiryu Davis mongo-c-driver 1.10.3 ===================== No change since 1.10.2; released to keep pace with libbson's version. -- A. Jesse Jiryu Davis mongo-c-driver 1.10.2 ===================== It is my pleasure to announce the MongoDB C Driver 1.10.2. This release fixes the libbson and libmongoc installed library filenames and SONAMEs on Linux. They had changed unintentionally with the switch to CMake in 1.10.0; they are now consistent with 1.9.x and previous releases. Thanks to Roberto C. Sánchez for the fix. Peace, A. Jesse Jiryu Davis mongo-c-driver 1.10.1 ===================== It is my pleasure to announce the MongoDB C Driver 1.10.1. This release fixes the following bugs introduced in version 1.10.0: * Client sessions were not prohibited with unacknowledged write concern and mongoc_bulk_operation_execute; now they are prohibited. Client sessions have been prohibited with all other unacknowledged writes since 1.10. * The "arrayFilters" update option, new in MongoDB 3.6 and supported since libmongoc 1.9.0, was inadvertently prohibited by mongoc_bulk_operation_update_one_with_opts and mongoc_bulk_operation_update_many_with_opts in 1.10. The option is now permitted again. * The mongoc-stat tool for displaying shared counters was disabled on Linux and not installed; it is now restored. Thanks to everyone who contributed to the development of this release. * A. Jesse Jiryu Davis * Jeremy Mikola * Remi Collet Peace, A. Jesse Jiryu Davis mongo-c-driver 1.10.0 ===================== It is my pleasure to announce MongoDB C Driver 1.10.0. This version drops support for MongoDB 2.6 and adds the following features and bugfixes: * libbson and libmongoc are now maintained in the mongo-c-driver repository, although they are still built as separate libraries, and libbson can still be used without libmongoc. * Building libbson and libmongoc now requires CMake on all platforms. The Autotools build scripts ("configure" and related scripts) have been deleted. See the "installing" page for updated instructions, including the new ENABLE_MONGOC option and changes to the ENABLE_BSON option. * IPv6 is now fully supported and conforms to RFC-6555. If a hostname has both IPv4 and IPv6 DNS records, the driver tries connecting with IPv6 first. If a connection can't be established after 250ms then IPv4 is tried in parallel. Whichever succeeds connection first cancels the other. The successful DNS result is cached for 10 minutes. * If CMake is configured with ENABLE_SSL=AUTO (the default), libmongoc now uses native TLS libraries on Mac and Windows, and OpenSSL everywhere else. Before, it would search for OpenSSL on all platforms and only use native TLS on Mac and Windows as a fallback. * The driver now handshakes SSL connections to multiple servers in a replica set or sharded cluster in parallel, so long as it uses OpenSSL or Windows SChannel. (SSL handshakes with Apple's Secure Transport are still serial.) A larger receive buffer with SChannel increases performance over slow connections. * All functions that accept read concern now prohibit it, if MongoDB is too old to support it (MongoDB 3.0). * Client sessions are now prohibited with unacknowledged writes. * mongoc_collection_find_and_modify_with_opts now prohibits write concern if MongoDB is too old to support it (MongoDB 3.0). * Other helper functions for commands that write, now prohibit write concern if MongoDB is too old to support it (pre-3.4): mongoc_client_read_write_command_with_opts mongoc_client_write_command_with_opts mongoc_collection_read_write_command_with_opts mongoc_collection_write_command_with_opts mongoc_database_read_write_command_with_opts mongoc_database_write_command_with_opts mongoc_collection_aggregate with $out mongoc_collection_drop_index_with_opts mongoc_collection_drop_with_opts mongoc_collection_rename_with_opts mongoc_database_drop_with_opts Write concern behavior is unchanged for regular CRUD functions. * Setting a negative writeConcern level of -2 or smaller, via the "opts" parameter to functions that accept BSON options, is now prohibited. The special "w" values -2 through -4 are only used internally. The deprecated "w=-1" is still allowed, as a synonym for "w=0". * The Kerberos URI option authMechanismProperties=CANONICALIZE_HOST_NAME:true is now implemented with the Windows Kerberos provider, SSPI. * This repository now includes GDB and LLDB customizations for pretty-printing bson_t structs as JSON while debugging. See the "debugging" page. * The internal preprocessor symbol HAVE_STRINGS_H has been renamed BSON_HAVE_STRINGS_H. If you maintain a handwritten bson-config.h you must rename this symbol. * The following helper functions do not work with mongoc_client_session_t, they are deprecated in favor of running MongoDB commands directly with a function like mongoc_client_read_command_with_opts: mongoc_client_get_server_status mongoc_collection_stats mongoc_collection_validate * mongoc_cursor_is_alive is now deprecated for mongoc_cursor_more, which is functionally equivalent. Thanks to everyone who contributed to the development of this release. * A. Jesse Jiryu Davis * Kevin Albertson * Roberto C.

Jesse Jiryu Davis mongo-c-driver 1.9.5 ==================== It is my pleasure to announce mongo-c-driver 1.9.5. This release fixes the following bugs: * New change streams API functions were not marked extern "C" * mongoc_collection_watch now accepts a pipeline argument as a BSON array, in addition to accepting a BSON document with a "pipeline" array field * Crashes in several change stream error handling paths * Commands could return false with an empty bson_error_t after a replica set reconfig * Network error messages omitted the command name when using OP_MSG Thanks to everyone who contributed to the development of this release. * A. Jesse Jiryu Davis * Kevin Albertson Peace, A. Jesse Jiryu Davis mongo-c-driver 1.9.4 ==================== It is my pleasure to announce mongo-c-driver 1.9.4.

This version drops support for MongoDB 2.4 and adds support for MongoDB 3.6 features: * New struct mongoc_change_stream_t to watch a collection for changes. * New struct mongoc_client_session_t represents a MongoDB 3.6 session, which supports causal consistency: you are guaranteed to read your writes and to perform monotonic reads, even when reading from secondaries or in a sharded cluster. * New functions that accept flexible options as a BSON document. These accept a "sessionId" option and any future options. In addition, the two new "update" functions accept the "arrayFilters" option that is new in MongoDB 3.6: mongoc_collection_insert_one mongoc_collection_insert_many mongoc_collection_update_one mongoc_collection_update_many mongoc_collection_replace_one mongoc_collection_delete_one mongoc_collection_delete_many mongoc_client_command_with_opts mongoc_database_command_with_opts mongoc_collection_command_with_opts mongoc_client_find_databases_with_opts mongoc_client_get_database_names_with_opts mongoc_collection_create_bulk_operation_with_opts mongoc_collection_find_indexes_with_opts mongoc_database_find_collections_with_opts mongoc_database_get_collection_names_with_opts * New URI option "retryWrites=true" safely and automatically retries certain write operations if the server is a MongoDB 3.6 replica set or sharded cluster. * Support for MongoDB OP_MSG wire protocol. Additional changes not specific to MongoDB 3.6: * Support for mongodb+srv URIs to query DNS for SRV and TXT records that configure the connection to MongoDB. * Support LibreSSL with CMake build * The "minPoolSize" URI option is deprecated: it's confusing and not useful. Bug fixes: * mongoc_bulk_operation_execute did not always initialize "reply". * Fix C99 pedantic warnings. Thanks to everyone who contributed to the development of this release. * A.

Jesse Jiryu Davis mongo-c-driver 1.8.2 ==================== It is my pleasure to announce mongo-c-driver 1.8.2. This release fixes the following bugs: * Remove option to bundle the Snappy compression library, it caused issues for programs linking to libmongoc * Fix pkg-config and CMake config file flags for programs that statically link to libmongoc when libmongoc is statically linked to zLib * The configure flag "--with-zlib=no" was ignored Crash in authentication when username is NULL Thanks to everyone who contributed to the development of this release. * A. Jesse Jiryu Davis * Derick Rethans * Hannes Magnusson * Jeremy Mikola Peace, A. Jesse Jiryu Davis mongo-c-driver 1.8.1 ==================== It is my pleasure to announce mongo-c-driver 1.8.1. This release fixes the following bugs: * Remove a syntax error in the configure script that affects some shells. * The configure script respects --with-zlib=system and --with-snappy=system. * The internal mongoc_server_description_t struct is properly reinitialized after a network error. * Fix the encoding of this NEWS file. Thanks to everyone who contributed to the development of this release. * A. Jesse Jiryu Davis * Jeremy Mikola Peace, A. Jesse Jiryu Davis mongo-c-driver 1.8.0 ==================== * The zLib and Snappy compression libraries are bundled if not available. Wire protocol compression is enabled on Windows. * mongoc_collection_find_and_modify_with_opts now respects a "writeConcern" field in the "extra" BSON document in its mongoc_find_and_modify_opts_t. * The command functions mongoc_client_read_write_command_with_opts, mongoc_database_read_write_command_with_opts, and mongoc_collection_read_write_command_with_opts now ignore the "read_prefs" parameter. * mongoc_collection_create_index and mongoc_collection_create_index_with_opts are both now deprecated. Use mongoc_database_write_command_with_opts instead; a guide to creating an index using that function has been added. * Use select, not WSAPoll, on Windows. * Always mark a server "Unknown" after a network error (besides a timeout). * mongoc_client_pool_t sends platform metadata to the server; before, only a single mongoc_client_t did. * New stream method mongoc_stream_timed_out. * Wire version checks introduced in 1.8.0 will prevent the driver from connecting to a future MongoDB server version if its wire protocol is incompatible. * New CMake option ENABLE_MAINTAINER_FLAGS. Thanks to everyone who contributed to the development of this release. * A. Jesse Jiryu Davis * Hannes Magnusson * Jeremy Mikola Peace, A. Jesse Jiryu Davis mongo-c-driver 1.7.0 ==================== It is my pleasure to announce mongo-c-driver 1.7.0. New features and bug fixes: * CMake build now installs .pc files for programs that link to libmongoc using pkg-config. Both the CMake and Autotools build systems now install .cmake files for programs that link to libmongoc using CMake. Linking to libmongoc statically or dynamically is now much more convenient. See the new tutorial section "Include and link libmongoc in your C program". * New CMake option ENABLE_STATIC can be ON, OFF, or AUTO (the default) * Minimum required CMake version has been increased to 3.1. * CMake remains experimental on non-Windows platforms and issues a warning now * Support for wire compression. * Support for snappy and zlib. MongoDB 3.4 only supports snappy, while zlib support is expected in MongoDB 3.6. The enable, configure mongoc like so: ./configure --with-snappy --with-zlib * New functions: mongoc_uri_get_compressors & mongoc_uri_set_compressors, to get and set compressor configuration on mongoc_uri_t * Added support for comma separated "compressors" connection string option (e.g. mongodb://localhost/?compressors=snappy,zlib) * Added support for configuring zlib compression level in the connection string (e.g. mongodb://localhost/?compressors=zlib&zlibcompressionlevel=8) * Now requires the use of CMake config files for libbson to build libmongoc with CMake * Added pkg-config support for libressl. * New function mongoc_uri_set_auth_mechanism to update the authentication mechanism of a mongoc_uri_t after it is created from a string. * New function mongoc_bulk_operation_insert_with_opts provides immediate error checking. * New function mongoc_uri_new_with_error provides a way to parse a connection string, and retrieve the failure reason, if any. * Support for MongoDB Connection String specification * All connection string options are now represented by MONGOC_URI_xxx macros * Paths to Unix Domain Sockets must be url encoded * Repeated options now issue warnings * Special characters in username, password and other values must be url encoded * Unsupported connection string options now issue warnings * Boolean values can now be represented as true/yes/y/t/1 and false/no/n/f/0. * Case is now preserved in Unix domain paths. * New function mongoc_cursor_error_document provides access to server's error reply if a query or command fails. * New function mongoc_write_concern_is_default determines whether any write concern options have been set, and mongoc_read_concern_is_default checks if read concern options are set. * mongoc_gridfs_find_one_with_opts optimized to use limit 1. Thanks to everyone who contributed to the development of this release. * Hannes Magnusson * A.

Jesse Jiryu Davis mongo-c-driver 1.6.0 ==================== It is my pleasure to announce mongo-c-driver 1.6.0. New features and bug fixes: * Enterprise authentication on Windows now uses the native GSSAPI library; Cyrus SASL is no longer required for enterprise auth on Windows. * BSON documents are more thoroughly validated before insert or update. * New function mongoc_uri_set_mechanism_properties to replace all the authMechanismProperties on an existing URI. * mongoc_uri_get_mechanism_properties asserts its inputs are not NULL. * For consistency with other MongoDB drivers, mongoc_collection_save is deprecated in favor of mongoc_collection_insert or mongoc_collection_update. * The driver is now built and continuously tested with MinGW-W64 on Windows. * Experimental support for HPUX. * The correct operation ids are now passed to Command Monitoring callbacks. * Fix a crash if the driver couldn't connect to the server to create an index. * The documentation is ported from Mallard XML to ReStructured Text, the HTML documentation is restyled, and numerous man page syntax errors fixed. * Getter functions for options in mongoc_find_and_modify_opts_t: * mongoc_find_and_modify_opts_get_bypass_document_validation * mongoc_find_and_modify_opts_get_fields * mongoc_find_and_modify_opts_get_flags * mongoc_find_and_modify_opts_get_max_time_ms * mongoc_find_and_modify_opts_get_sort * mongoc_find_and_modify_opts_get_update * All public functions now have the __cdecl calling convention on Windows.

Jesse Jiryu Davis mongo-c-driver 1.5.5 ==================== It is my pleasure to announce mongo-c-driver 1.5.5. This release fixes bugs parsing the localThresholdMS option from the MongoDB URI, and a crash in mongoc_cursor_destroy if "query" or "filter" are invalid. Thanks to Jeremy Mikola. Peace, A. Jesse Jiryu Davis mongo-c-driver 1.5.4 ==================== It is my pleasure to announce mongo-c-driver 1.5.4. This release fixes an error in cursor iteration when a readConcern is set. Thanks to Jeremy Mikola and Hannes Magnusson. Peace, A. Jesse Jiryu Davis mongo-c-driver 1.5.3 ==================== This release fixes a bug that prevented connecting to IPv4-only MongoDB servers by hostname. https://jira.mongodb.org/browse/CDRIVER-1988 The driver has reverted to its 1.5.1 behavior: it connects to MongoDB over IPv6 if given an IPv6 connection string like "mongodb://[::1]", and requires an IPv4 connection when given a hostname like "mongodb://localhost". Peace, A. Jesse Jiryu Davis mongo-c-driver 1.5.2 ==================== It is my pleasure to announce mongo-c-driver 1.5.2. Thanks to everyone who contributed to the development of this release. New bug fixes: * CDRIVER-1975 allow mixed $ and non-$ query ops. * CDRIVER-1972 Support for ipv6 hostnames. * CDRIVER-1971 Missing exports of mongoc_gridfs_file_set_*() functions. * CDRIVER-1970 update define constants for "find" opts to be unique. * CDRIVER-1964 Windows CA stores should be opened with read-only flag.

Jesse Jiryu Davis * Alexey Ponomarev * Peter Beckman * Rockford Wei Peace, Hannes Magnusson mongo-c-driver 1.5.1 ==================== It is my pleasure to announce mongo-c-driver 1.5.1. This is a bugfix release: * Fix SEGFAULT with performance counters on NUMA (thanks to Jonathan Wang). * Prevent rare assertion error in mongoc_cluster_stream_for_server. * Improve error messages from auth failure. * Escape quotes when appending CFLAGS to handshake metadata. * Fix OpenSSL header lookups in non-default paths. * Fix build failure with LibreSSL. Thanks to everyone who contributed to the development of this release. * A. Jesse Jiryu Davis * Hannes Magnusson * Jeroen Ooms * Jonathan Wang Peace, A. Jesse Jiryu Davis mongo-c-driver 1.5.0 ==================== It is my pleasure to announce mongo-c-driver 1.5.0. New features and bug fixes: * MongoDB 3.4 Support * New URI and read preference option, "maxStalenessSeconds" * MongoDB Handshake * writeConcern and readConcern enhancements * Collation allows users to specify language-specific rules for string comparison when sorting documents. See the code examples for mongoc_client_read_command_with_opts, mongoc_collection_count_with_opts, mongoc_collection_find_with_opts, and mongoc_index_opt_t, as well as the "Setting Collation Order" section of the "Bulk Write Operations" guide. * mongoc_collection_count_with_opts uses the collection's read preference if none is passed in * Improved TLS support * Fixed LibreSSL (libssl) support * Added LibreSSL (libtls) support * Fixed Secure Channel build on VS 2010 * OpenSSL now supports SNI (all others already do) * Additional features for Application Performance Monitoring: * mongoc_topology_description_has_writable_server * mongoc_topology_description_has_readable_server * New functions accept flexible options as a BSON document: * mongoc_collection_find_with_opts * mongoc_client_read_command_with_opts * mongoc_client_write_command_with_opts * mongoc_client_read_write_command_with_opts * mongoc_database_read_command_with_opts * mongoc_database_write_command_with_opts * mongoc_database_read_write_command_with_opts * mongoc_collection_read_command_with_opts * mongoc_collection_write_command_with_opts * mongoc_collection_read_write_command_with_opts * mongoc_gridfs_find_with_opts * mongoc_gridfs_find_one_with_opts * mongoc_collection_find is now deprecated in favor of mongoc_collection_find_with_opts. * New helper function to include read concern in one of the above function's options parameter: mongoc_read_concern_append. * mongoc_client_command no longer applies the client's read preference and read concern by default. Same change for mongoc_database_command and mongoc_collection_command. * mongoc_collection_count_with_opts now applies the collection's read preference if no read preference is provided * mongoc_collection_create_index and mongoc_collection_drop_index now apply the collection's write concern. * connectTimeoutMS timer now begins after DNS resolution, and resets for each interface attempted (e.g., if the driver first tries IPv6, then IPv4). * New error code MONGOC_ERROR_DUPLICATE_KEY. * mongoc_collection_find no longer treats the "filter" key specially in queries - querying for a document with a key named "filter" is the same now as any other key. * The server description parameter to the following functions is "const": * mongoc_server_description_host * mongoc_server_description_id * mongoc_server_description_ismaster * mongoc_server_description_round_trip_time * mongoc_server_description_type * Exported symbols are no longer declared in separate export files. This could break ABI with applications using clang, which previously exported symbols from the internal private ABI. * mongoc no longer crashes when multi roundtrip bulk operation fails. * Added support for the new readConcernLevel "linearizable". * Clients now check for misformatted "readPreferenceTags" in URI. * New CMake option ENABLE_TRACING allows debug output, which before had only been available with "configure --enable-tracing". * Bugfix: "PossiblePrimary"-type replicas could be selected for reads * Bugfixes: The random number generator used to select servers is now properly seeded, and secondary queries are now properly distributed according to localThresholdMS, not just to the lowest-latency secondary. * mongoc_collection_insert, mongoc_collection_update, mongoc_collection_remove consistently use domain MONGOC_ERROR_BSON, code MONGOC_ERROR_BSON_INVALID if passed oversized BSON, and MONGOC_ERROR_COLLECTION for other errors. mongoc_bulk_operation_execute continues to use MONGOC_ERROR_COMMAND for all errors. * If mongoc_client_pool_t fails to start its scanner thread in the background, it logs and aborts instead of silently continuing, then failing to connect. * The driver now updates its view of the whole topology with information from each new connection handshake. * mongoc_client_set_apm_callbacks can be used repeatedly to change or clear the list of monitoring callbacks. * Improved error reporting when the driver fails to reach the server. Deprecations: * mongoc_collection_find is deprecated for mongoc_collection_find_with_opts. Removed configure flags: * --enable-experimental has been removed. All previously experimental features are now always on. * The configure option "--enable-hardening" had had no effect. It is removed in favor of system-wide compiler configuration. Thanks to everyone who contributed to the development of this release. * A. Jesse Jiryu Davis * Hannes Magnusson * Fiona Rowan * Ian Boros * Remi Collet * Brian McCarthy * Jeroen Ooms * J. Rassi * Christoph Schwarz * Alexey Vorobeyev Peace, A. Jesse Jiryu Davis mongo-c-driver 1.4.2 ==================== It is my pleasure to announce mongo-c-driver 1.4.2. This release fixes bugs in "minPoolSize" logic, see CDRIVER-1558 for details. Peace, A. Jesse Jiryu Davis mongo-c-driver 1.4.1 ==================== It is my pleasure to announce mongo-c-driver 1.4.1. This is a bugfix release: * mongoc_client_get_server_descriptions could return a list including NULLs * Tailable cursors on MongoDB 3.2 only worked with MONGOC_QUERY_AWAIT_DATA * Spurious warnings with MONGOC_DISABLE_SHM Thanks to everyone who contributed to the development of this release. * A. Jesse Jiryu Davis * Hannes Magnusson Peace, A. Jesse Jiryu Davis mongo-c-driver 1.4.0 ==================== It is my pleasure to announce the release of mongo-c-driver 1.4.0. TLS --- The driver can now use the native TLS and crypto functions included in macOS and Windows. OpenSSL is no longer required for TLS or authentication on Mac or Windows. By default, OpenSSL is used if available, the default will switch in version 2.0 to prefer native TLS. For native TLS on Mac: ./configure --enable-ssl=darwin For Windows: cmake "-DENABLE_SSL=WINDOWS" -G "Visual Studio 10 Win64" "-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver" All of the TLS implementations now load the native default certificate store, with OpenSSL on Windows falling back on the Windows native certificate store if no other can be found. The "ca_dir" field on mongoc_ssl_opt_t is only supported by OpenSSL. All other fields, including "pem_file", are supported by all implementations. A new field, "allow_invalid_hostname", has been added to mongoc_ssl_opt_t and is preferred over the existing "allow_invalid_certificate" to disable hostname verification. The driver now supports the latest OpenSSL 1.1 in addition to past versions. Application Performance Monitoring ---------------------------------- The driver implements the MongoDB Command Monitoring Spec. Applications can record the duration and other details of every operation the driver performs on the server. See "Introduction to Application Performance Monitoring" in the docs. Error API --------- New functions mongoc_client_set_error_api and mongoc_client_pool_set_error_api allow applications to distinguish client and server errors. See the "Error Reporting" doc. Unacknowledged Write Results ---------------------------- Unacknowledged writes (writes whose mongoc_write_concern_t "w" value is zero) now reply with an empty document instead of one with nInserted: 0, nUpdated: 0, and so on. Command functions now ignore the read preferences set on a client, database, or collection. Instead, they use the mongoc_read_prefs_t passed in explicitly, or default to "primary". This change was made to bring them in line with the Server Selection Spec. These are the affected functions: * mongoc_client_command * mongoc_client_command_simple * mongoc_database_command * mongoc_database_command_simple * mongoc_collection_command * mongoc_collection_command_simple On the other hand, the following command-specific helper functions now use the collection's read preference: * mongoc_collection_count * mongoc_collection_stats New functions to send maxTimeMS or any arbitrary options with findAndModify: * mongoc_find_and_modify_opts_set_max_time_ms * mongoc_find_and_modify_opts_append New function to include a write concern with a generic command function like mongoc_client_command_simple: * mongoc_write_concern_append Public API For Higher-Level Drivers ----------------------------------- New functions support language drivers (specifically the PHP and HHVM drivers) using only the libmongoc public API: * mongoc_bulk_operation_get_hint * mongoc_client_command_simple_with_server_id * mongoc_client_get_server_description * mongoc_client_get_server_description_by_id * mongoc_client_get_server_descriptions * mongoc_client_select_server * mongoc_cursor_get_limit * mongoc_cursor_new_from_command_reply * mongoc_cursor_set_hint * mongoc_cursor_set_limit * mongoc_log_trace_disable * mongoc_log_trace_enable * mongoc_server_description_ismaster * mongoc_server_description_round_trip_time * mongoc_server_description_type * mongoc_server_descriptions_destroy_all * mongoc_uri_get_option_as_bool * mongoc_uri_get_option_as_int32 * mongoc_uri_get_option_as_utf8 * mongoc_uri_option_is_bool * mongoc_uri_option_is_int32 * mongoc_uri_option_is_utf8 * mongoc_uri_set_auth_source * mongoc_uri_set_database * mongoc_uri_set_option_as_bool * mongoc_uri_set_option_as_int32 * mongoc_uri_set_option_as_utf8 * mongoc_uri_set_password * mongoc_uri_set_read_concern * mongoc_uri_set_read_prefs_t * mongoc_uri_set_username * mongoc_uri_set_write_concern * mongoc_write_concern_is_acknowledged * mongoc_write_concern_is_valid * mongoc_write_concern_journal_is_set Now that these public APIs are available, the PHP drivers no longer define the MONGOC_I_AM_A_DRIVER preprocessor symbol to access private APIs. The symbol is removed from C Driver headers, and libmongoc-priv.so is no longer installed. Other Features -------------- * New connection string option "localThresholdMS". * zSeries and POWER8 platform support. * Performance enhancements, reduce allocation and copying in command code. * All man page names now begin with "mongoc_" to avoid install conflicts. * New function mongoc_gridfs_file_set_id. Deprecations ------------ Automatically calling mongoc_init and mongoc_cleanup is a GCC-specific feature that is now deprecated, and will be removed in version 2. The driver should be built with: ./configure --disable-automatic-init-and-cleanup Or: cmake "-DENABLE_AUTOMATIC_INIT_AND_CLEANUP=OFF" -G "Visual Studio 10 Win64" "-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver" In this configuration, applications must explicitly init and cleanup libmongoc. Deprecated functions: * mongoc_write_concern_get_fsync * mongoc_write_concern_set_fsync Notable Bug Fixes ----------------- * Logic bugs using tag sets to select replica set members with complex configs * mongoc_client_get_database_names no longer filters out a replica set member's "local" database. * mongoc_client_get_gridfs now ensures the proper indexes on the files and chunks collections. * SecondaryPreferred fails if primary matches tags but secondaries don't. * mongoc_collection_find_and_modify_with_opts can return true on writeConcernError. * mongoc_collection_validate doesn't always init "reply". * The strings referred to by mongoc_ssl_opt_t, like pem_file and ca_file, are now copied into the client or client pool by mongoc_client_set_ssl_opts or mongoc_client_pool_set_ssl_opts, and need not be kept valid afterward. * mongoc_collection_count_with_opts ignored flags and read_prefs. * minPoolSize of 0 should mean "no minimum". * mongoc_database_create_collection should always use the primary. * The GSSAPI properties SERVICE_NAME and CANONICALIZE_HOST_NAME are now properly parsed from the URI, see the "Authentication" doc for details. * Comprehensive compatibility with various C standards and compilers.

Jesse Jiryu Davis mongo-c-driver 1.3.5 ==================== It is my pleasure to announce mongo-c-driver 1.3.5. This release fixes a crash in mongoc_cleanup when an allocator had been set with bson_mem_set_vtable, and introduces a configure option MONGOC_NO_AUTOMATIC_GLOBALS which prevents code built with GCC from automatically calling mongoc_init and mongoc_cleanup when your code does not. Thanks to everyone who contributed to the development of this release. * A. Jesse Jiryu Davis * Hannes Magnusson Peace, A. Jesse Jiryu Davis mongo-c-driver 1.3.4 ==================== It is my pleasure to announce the MongoDB C Driver 1.3.4. This release fixes a security vulnerability: when a mongoc_client_t uses SSL and is disconnected, it failed to re-verify the server certificate after reconnecting. This flaw affects single clients, not pooled ones. Thanks to everyone who contributed to the development of this release. * A. Jesse Jiryu Davis * Hannes Magnusson * Remi Collet Peace, A. Jesse Jiryu Davis mongo-c-driver 1.3.3 ==================== It is my pleasure to announce MongoDB C Driver 1.3.3. This fixes a bug where a slightly-oversized bulk write operation was not split into batches; instead, it was sent whole to the server, which rejected it. Peace, A. Jesse Jiryu Davis mongo-c-driver 1.3.2 ==================== It is my pleasure to announce MongoDB C Driver 1.3.2. This is a bugfix release: * A socket is properly discarded after a network error from a command. * mongoc_database_get_collection now copies the database's read preferences, read concern, and write concern, instead of copying the client's. * mongoc_cursor_t's private struct now allows a negative limit. Thanks to everyone who contributed to this release. * A. Jesse Jiryu Davis * Jeremy Mikola * Hannes Magnusson Peace, A. Jesse Jiryu Davis mongo-c-driver 1.3.1 ==================== It is my pleasure to announce MongoDB C Driver 1.3.1. This is a bugfix release: * mongoc_client_get_gridfs now copies the client's read preferences, read concern, and write concern to the newly created mongoc_gridfs_t. Before this fix, GridFS operations were always executed with the default config: data was read from the primary, with the read concern level "local", and written with write concern "acknowledged". Now, if you have configured any of these options on the mongoc_client_t, they are respected by the mongoc_gridfs_t. * CMakeLists.txt now includes and installs the pkg-config files. Thanks to everyone who contributed to this release. * A. Jesse Jiryu Davis * Hannes Magnusson * Christopher Wang * Jean-Bernard Jansen * Jeremy Mikola * Jeroen Ooms Peace, A. Jesse Jiryu Davis mongo-c-driver 1.3.0 ==================== It is my pleasure to announce to you the release of the MongoDB C Driver 1.3.0. Changes since the release candidate 1.3.0-rc0: * Fix a cursor bug introduced on big-endian platforms in 1.3.0-beta0. * Improve documentation for mongoc_host_list_t. * Move private mongoc_host_list_t functions from public header. * Refactor the build system to declare library version in one place. All new features and changes since the previous stable release, 1.2.1: * If the driver is compiled without SSL support but a URI with "ssl=true" is passed to mongoc_client_new, mongoc_client_new_from_uri, or mongoc_client_pool_new, the function logs an error and returns NULL. Before, the driver would attempt a non-SSL connection. * mongoc_collection_find_and_modify will now apply the mongoc_collection_t's write_concern_t when talking to MongoDB 3.2. * Support for MongoDB 3.2's "readConcern" feature for queries, counts, and aggregations. The option "readConcernLevel" is now accepted in the MongoDB URI. New struct mongoc_read_concern_t, and functions operating on it: - mongoc_client_get_read_concern - mongoc_client_set_read_concern - mongoc_database_get_read_concern - mongoc_database_set_read_concern - mongoc_collection_get_read_concern - mongoc_collection_set_read_concern - mongoc_read_concern_copy - mongoc_read_concern_destroy - mongoc_read_concern_get_level - mongoc_read_concern_new - mongoc_read_concern_set_level - mongoc_uri_get_read_concern * Support for MongoDB 3.2's "bypassDocumentValidation" option for writes. * New struct mongoc_bulk_write_flags_t and related functions: - mongoc_bulk_operation_set_bypass_document_validation * New struct mongoc_find_and_modify_opts_t and related functions: - mongoc_find_and_modify_opts_new - mongoc_find_and_modify_opts_destroy - mongoc_find_and_modify_opts_set_sort - mongoc_find_and_modify_opts_set_update - mongoc_find_and_modify_opts_set_fields - mongoc_find_and_modify_opts_set_flags - mongoc_find_and_modify_opts_set_bypass_document_validation - mongoc_collection_find_and_modify_with_opts * New functions to copy database and collection handles: - mongoc_collection_copy - mongoc_database_copy * Support for MongoDB 3.2 wire protocol: use commands in place of OP_QUERY, OP_GETMORE, and OP_KILLCURSORS messages. * To explain a query plan with MongoDB 3.2, you must now call the "explain" command, instead of including the "$explain" key in a mongoc_collection_find query. See the mongoc_collection_find documentation page for details. * Configurable wait time on tailable cursors with MongoDB 3.2: - mongoc_cursor_get_max_await_time_ms - mongoc_cursor_set_max_await_time_ms * Use electionId to detect a stale replica set primary during a network split. * Disconnect from replica set members whose "me" field does not match the connection address. * The client side matching feature, mongoc_matcher_t and related functions, are deprecated and scheduled for removal in version 2.0. * New CMake options ENABLE_SSL, ENABLE_SASL, ENABLE_TESTS, and ENABLE_EXAMPLES. * Use constant-time comparison when verifying credentials. * Combine environment's CFLAGS with configure options when building. * Improved man page output and "whatis" entries. There are extensive bugfixes and improvements in GridFS since 1.2.1, including: * Handle seeking, reading, and writing past the end of a GridFS file. * If a GridFS chunk is missing, mongoc_gridfs_file_readv sets file->error to domain MONGOC_ERROR_GRIDFS and a new code MONGOC_ERROR_GRIDFS_CHUNK_MISSING. * Optimization for long seeks forward with mongoc_gridfs_file_seek. Other fixes since 1.2.1: * Memory leaks in mongoc_database_has_collection and mongoc_cursor_next. * Report writeConcern failures from findAndModify and from legacy writes. * Memory leak in mongoc_database_find_collections. * Set OP_QUERY's nToReturn from the provided limit. * Fix compiler warnings and errors, especially with Visual Studio 2015, GCC 4.8, and IBM XL C. * Bugs and typos in tutorial examples.

Jesse Jiryu Davis mongo-c-driver 1.3.0-rc0 ======================== It is my pleasure to announce to you the first release candidate of MongoDB C driver 1.3.0. It includes additive ABI changes and bugfixes, and support for the upcoming MongoDB 3.2. It is compatible with MongoDB 2.4 and later. New features and changes since 1.3.0-beta0: * If the driver is compiled without SSL support but a URI with "ssl=true" is passed to mongoc_client_new, mongoc_client_new_from_uri, or mongoc_client_pool_new, the function logs an error and returns NULL. Before, the driver would attempt a non-SSL connection. * New functions to copy database and collection handles: - mongoc_collection_copy - mongoc_database_copy * If a GridFS chunk is missing, mongoc_gridfs_file_readv sets file->error to domain MONGOC_ERROR_GRIDFS and a new code MONGOC_ERROR_GRIDFS_CHUNK_MISSING. * Use electionId to detect a stale replica set primary during a network split. * Disconnect from replica set members whose "me" field does not match the connection address. * The client side matching feature, mongoc_matcher_t and related functions, are deprecated and scheduled for removal in version 2.0. * New CMake options ENABLE_SSL, ENABLE_SASL, ENABLE_TESTS, and ENABLE_EXAMPLES. * The build system is refactored to declare the current version and latest release in one place. Other fixes: * Memory leaks in mongoc_database_has_collection and mongoc_cursor_next. * Report writeConcern failures from findAndModify and from legacy writes. Thanks to everyone who contributed to this release candidate. * A. Jesse Jiryu Davis * Hannes Magnusson * Matt Cotter * Claudio Canella * Victor Leschuk * Flavio Medeiros * Christopher Wang Peace, A. Jesse Jiryu Davis mongo-c-driver 1.3.0-beta0 ========================== It is my pleasure to announce to you the beta of MongoDB C driver 1.3.0. This beta includes additive ABI changes and bugfixes, and support for the upcoming MongoDB 3.2. It is compatible with MongoDB 2.4 and later. New features and changes: * mongoc_collection_find_and_modify will now apply the mongoc_collection_t's write_concern_t when talking to MongoDB 3.2. * Support for MongoDB 3.2's "readConcern" feature for queries, counts, and aggregations. The option "readConcernLevel" is now accepted in the MongoDB URI. New struct mongoc_read_concern_t, and functions operating on it: - mongoc_client_get_read_concern - mongoc_client_set_read_concern - mongoc_database_get_read_concern - mongoc_database_set_read_concern - mongoc_collection_get_read_concern - mongoc_collection_set_read_concern - mongoc_read_concern_copy - mongoc_read_concern_destroy - mongoc_read_concern_get_level - mongoc_read_concern_new - mongoc_read_concern_set_level - mongoc_uri_get_read_concern * Support for MongoDB 3.2's "bypassDocumentValidation" option for writes. * New struct mongoc_bulk_write_flags_t and related functions: - mongoc_bulk_operation_set_bypass_document_validation * New struct mongoc_find_and_modify_opts_t and related functions: - mongoc_find_and_modify_opts_new - mongoc_find_and_modify_opts_destroy - mongoc_find_and_modify_opts_set_sort - mongoc_find_and_modify_opts_set_update - mongoc_find_and_modify_opts_set_fields - mongoc_find_and_modify_opts_set_flags - mongoc_find_and_modify_opts_set_bypass_document_validation - mongoc_collection_find_and_modify_with_opts * Configurable wait time on tailable cursors with MongoDB 3.2: - mongoc_cursor_get_max_await_time_ms - mongoc_cursor_set_max_await_time_ms * Support for MongoDB 3.2 wire protocol: use commands in place of OP_QUERY, OP_GETMORE, and OP_KILLCURSORS messages. * To explain a query plan with MongoDB 3.2, you must now call the "explain" command, instead of including the "$explain" key in a mongoc_collection_find query. See the mongoc_collection_find documentation page for details. * Use constant-time comparison when verifying credentials. * Combine environment's CFLAGS with configure options when building. * Improved man page output and "whatis" entries. Extensive bugfixes and improvements in GridFS, including: * Handle seeking, reading, and writing past the end of a GridFS file. * Optimization for long seeks forward with mongoc_gridfs_file_seek. Other fixes: * Memory leak in mongoc_database_find_collections. * Set OP_QUERY's nToReturn from the provided limit. * Fix compiler warnings and errors, especially with Visual Studio 2015, GCC 4.8, and IBM XL C. * Bugs and typos in tutorial examples Thanks to everyone who contributed to this beta release. * A.

Jesse Jiryu Davis mongo-c-driver 1.2.2 ==================== It is my pleasure to announce to you the MongoDB C driver 1.2.2. This release fixes a rare bug where the driver can direct reads to hidden secondaries unintentionally. It also includes fixes and improvements to the build system. Peace, A. Jesse Jiryu Davis mongo-c-driver 1.2.1 ==================== It is my pleasure to announce to you the MongoDB C driver 1.2.1. This release includes critical bugfixes for SSL connections with mongoc_client_pool_t, and for Unix domain socket connections. The documentation is updated for a change introduced in version 1.2.0: mongoc_client_set_ssl_opts and mongoc_client_pool_set_ssl_opts now configure the driver to require an SSL connection to the server, even if "ssl=true" is omitted from the MongoDB URI. Before, SSL options were ignored unless "ssl=true" was included in the URI. The build instructions are improved, including the steps to build with OpenSSL on OS X El Capitan. Build errors and warnings are fixed for clang in gnu99 mode and MinGW. Thanks to everyone who contributed to this version of libmongoc. * A. Jesse Jiryu Davis * Hannes Magnusson * Tamas Nagy Peace, A. Jesse Jiryu Davis mongo-c-driver 1.2.0 ==================== It is my pleasure to announce to you the MongoDB C driver 1.2.0. This is a stable release with additive ABI changes and bugfixes. It is compatible with MongoDB version 2.4 and later. The following notes summarize changes since the previous stable release, 1.1.11, including changes in the 1.2.0 betas and release candidate. This version rewrites mongoc_client_t's internals to match two important new specs for MongoDB drivers: the Server Discovery And Monitoring Spec and the Server Selection Spec. The rewritten client has many advantages: * All replica set members or mongos servers are discovered and periodically checked in parallel. The driver's performance is dramatically better and more predictable with multi-server deployments, or with a flaky network, or when some servers are slow or down. * Clients from the same mongoc_client_pool_t share a background thread that discovers and monitors all servers in parallel. * Unnecessary round trips for server checks and pings are eliminated. * Behavior is documented in the specs, and consistent with other drivers, even in complex or unusual scenarios. * The URI's "replicaSet" option is enforced: the driver now refuses to connect to a server unless it is a member of a replica set with the correct setName. * Many race conditions related to changing deployment conditions are fixed. To conform to the new specs, the client now accepts these options in the MongoDB URI; see the mongoc_uri_t documentation for details: * heartbeatFrequencyMS * serverSelectionTimeoutMS * serverSelectionTryOnce * socketCheckIntervalMS Other features: * All timeouts that can be configured in the URI now interpret 0 to mean "use the default value for this timeout". * The client's read preference can be configured in the URI with the new options "readPreference" and "readPreferenceTags"; see the mongoc_uri_t documentation. * The new mongoc_uri_get_read_prefs_t function retrieves both the read mode and tags from a mongoc_uri_t. * New accessors mongoc_gridfs_file_get_id, mongoc_client_get_default_database, and mongoc_bulk_operation_get_write_concern. * Debug tracing can be controlled at runtime with mongoc_log_trace_enable and mongoc_log_trace_disable. * Set mongoc_client_pool_t's size with mongoc_client_pool_min_size() and mongoc_client_pool_max_size(). Other changes: * Enable runtime asserts in release build. * The libbson submodule's URL now uses the recommended https://, not git:// * mongoc_client_kill_cursor is now deprecated and will be removed in 2.0. * The write concern "w=-1" is documented as obsolete. These notable bugs have been fixed since 1.1.11: * The driver now uses the server's maxWireVersion to avoid an error and extra round-trip when executing aggregations on MongoDB 2.4 and older. * Much improved reporting of network errors, unavailable servers, and authentication failure * Off-by-one error in mongoc_gridfs_file_seek with mode SEEK_END * The writeConcernErrors field of bulk results is properly formatted. * A cursor with a server "hint" sets slaveOkay and / or $readPreference. * Destroying an exhaust cursor must close its socket * "wtimeoutms" was ignored for write concerns besides "majority". * Bulk write operations might fail in mixed-version sharded clusters with some pre-2.6 mongos servers. * A variety of bugs and incorrect results in mongoc_bulk_operation_execute. * Numerous compiler warnings and build failures on various platforms. * Copious refinements to the documentation.

Jesse Jiryu Davis mongo-c-driver 1.2.0-rc0 ======================== It is my pleasure to announce the release candidate of the MongoDB C driver 1.2.0. It includes features and bugfixes developed since 1.2.0-beta1. Notable bugs fixed: * Much improved reporting of network errors, unavailable servers, and authentication failure * Destroying an exhaust cursor must close its socket * Various bugs in server reconnection logic * mongoc_collection_aggregate returned invalid cursor after failure * Wrong error message after failed network write on Sparc * Missing JSON test files in release tarball Other changes: * Enable runtime asserts in release build. * mongoc_client_kill_cursor is now deprecated and will be removed in version 2.0. This release candidate also includes all bugfixes from 1.1.11. Version 1.2.0 final will be a stable release with additive ABI changes and bugfixes. It is compatible with MongoDB version 2.4 and later. Thanks to everyone who contributed to this version of libmongoc. * A.

Jesse Jiryu Davis mongo-c-driver 1.2.0-beta1 ========================== It is my pleasure to announce the second beta release of the MongoDB C driver 1.2.0. It includes features and bugfixes developed since 1.2.0-beta. New features: * Set mongoc_client_pool_t's size with mongoc_client_pool_min_size() and mongoc_client_pool_max_size(). * The write concern "w=-1" is now documented as obsolete. * Abundant fixes and additions to the documentation, beyond those in the previous beta. Notable bugs fixed: * Crashes and races in several replica set scenarios. * The driver now uses the server's maxWireVersion to avoid an error and extra round-trip when executing aggregations on MongoDB 2.4 and older. * Fixed network error handling in multiple code paths. * connectTimeoutMS limits the time the driver can spend reconnecting to servers in single-threaded (non-pooled) mode with serverSelectionTryOnce. Version 1.2.0 final will be a stable release with additive ABI changes and bugfixes. It is compatible with MongoDB version 2.4 and later.

Jesse Jiryu Davis mongo-c-driver 1.1.6 ==================== It is my pleasure to announce to you the 1.1.6 release of the MongoDB C driver. This is a patch release with performance enhancements and bug fixes: * mongoc_bulk_operation_execute now coalesces consecutive update operations into a single message to a MongoDB 2.6+ server, yielding huge performance gains. Same for remove operations. (Inserts were always coalesced.) * Large numbers of insert operations are now properly batched according to number of documents and total data size. * GSSAPI / Kerberos auth now works. * The driver no longer tries three times in vain to reconnect to a primary, so socketTimeoutMS and connectTimeoutMS now behave *closer* to what you expect for replica sets with down members. A full fix awaits 1.2.0. I snuck in a feature: * mongoc_matcher_t now supports basic subdocument and array matching Thanks to everyone who contributed to the development of this point release for libmongoc. * A. Jesse Jiryu Davis * Jason Carey * Kai Mast * Matt Cotter Peace, A. Jesse Jiryu Davis mongo-c-driver 1.1.5 ==================== It is my pleasure to announce to you the 1.1.5 release of the MongoDB C driver.

Thanks to everyone who contributed to the development of this driver! * Christian Hergert * Jason Carey * Gary Murakami * Christian Heckl * Frank Watson Song * Hannes Magnusson * Jérôme Lebel * Kyle Suarez * Maga Napanga * Michael Kuhn * Vincent Giersch * essentia44 * yuqing Happy Hacking! -- Christian Hergert mongo-c-driver 0.98.2 ===================== One final step before our journey to 1.0! This is a relatively small release, adding some features needed for drivers building on top of the C driver. A new libmongoc-priv.so library is installed that does not have symbols hidden. You can access private headers via the -private.h variants. This means you will need to recompile your project every time the library is changed (if you use those private headers, as they are subject to change). A special thanks to Hannes Magnusson for patches in this release. See `git shortlog 0.98.0..0.98.2` for a list of all the changes. -- Christian Hergert mongo-c-driver 0.98.0 ===================== Another step in the rapidly approaching path to 1.0! This release is primarily a bugfix release and stablization effort as we approach 1.0 of the MongoDB C driver. This release requires 0.98.0 of Libbson for improvements to the memory management system. You can now setup custom memory allocators at the start of the process. This is a RC release that with a few improvements will likely become 1.0. A special thanks to the following for patches in this cycle: * Kyle Suarez * yuqing See `git shortlog 0.96.4..0.98.0` for a list of all the changes. -- Christian Hergert mongo-c-driver 0.96.4 ===================== Another incremental feature update and bugfix release! In this release, you will find the following changes: * build/mci.sh script for automatically building Debian packages, RPMs, and Solaris packaging based on the host operating system. * Various libbson improvements, now depending on 0.8.4. * Alignment fixes for Solaris Studio C compiler via libbson. * Addition of mongoc_gridfs_remove_by_filename() for removing a file from gridfs by filename. * client command functions can now take a fully qualified namespace. * collections can now support names that indicate a command namespace. * Commands will no longer fail if they do not contain an "ok" field. * OP_QUERY will now set the slaveOk bit in the wire protocol if * readPreferences are set to non-PRIMARY. * Various documentation and build fixes. Thanks again to all the contributors, and happy hacking! mongo-c-driver 0.96.2 ===================== Hot on the heels of 0.96.0 we would like to present mongo-c-driver 0.96.2! This is primarily a bugfix release. Included in this release are: * Ensure batchSize is used in cursor GETMORE operations with `aggregate`. * Ensure enough buffer space is allocated for incoming RPC when buffering from a stream. * Require libbson 0.8.2 for more robust `bson_next_power_of_two()` when using `size_t` and BCON compilation fix with C++. * Handle cursor id's that are not 64-bit values in response from `aggregate` command. * Handle upsert on MongoDB < 2.6 when _id does not contain an `ObjectId`. * Use 100 for default batchSize in `aggregate` command. Happy Hacking! mongo-c-driver 0.96.0 ===================== It's that time again, time for another mongo-c-driver release! This release includes much new documentation, which can be found at http://docs.mongodb.org/ecosystem/drivers/c/. Additionally, this release improves support for various exotic systems. Solaris 10 is supported much better on SPARC and x86_64 based systems. Some workarounds for mixed-mode sharded-clusters have been added to improve resiliency when rolling upgrades are performed. Build improvements have been added to help us detect SASL and SSL implementations on platforms that do not support pkg-config. This should simplify building for some of you. We've added some more logging to SASL authentication to help debug authentication failures. A bug causing an abort() when SSL is used and a server is down has been fixed. We've renamed various _delete() functions to _remove() to provide consistency with other MongoDB drivers. You can now specify SSL options for client pools. -D_REENTRANT is always defined now on Solaris to help with errno detection. This may not have been done before if using a non-GCC platform with pthreads. A bug was fixed where timeouts could have been 1000x longer than expected due to failure to convert from microseconds to milliseconds. A bug was fixed with authentication in sharded cluster and replica set scenarios. Happy Hacking! mongo-c-driver 0.94.2 ===================== Hot on the heels of 0.94.0 is 0.94.2, a bugfix release. A bug has been fixed when using TLS streams and large result sets. In this release, we added support for Sun's C compiler (Sun Pro C) on Solaris. This allows for builds on Solaris 10 with SPARC using the native toolchain. This release contains a couple of fixes in libbson as well. Keep those bug reports coming, and as always, Happy Hacking! mongo-c-driver 0.94.0 ===================== The mongo-c-driver team is proud to announce the release of 0.94.0. This release is a followup to the previous release adding more features to be found in MongoDB 2.6. You will find some new API's, bug fixes, and more documentation. Under the hood, 0.94.0 uses the new write-commands as part of MongoDB 2.6 when it discovers it is communicating with a MongoDB server. There is now a bulk operation API (See `mongoc-bulk-operation.h`). Helpers for common server commands have been added. You can find most of them `mongoc-collection.h`. To simply using mongo-c-driver from Windows, we've included pre-built binaries on the release page. Thanks to all of the contributors this release! Happy Hacking! mongo-c-driver 0.92.0 ===================== The mongo-c-driver team is proud to announce the release of 0.92.0.

Happy Hacking! Libmongoc 0.90.0 ================ This is the initial release of the new Libmongoc. We chose 0.90.0 for the release version to differentiate ourselves from the, now legacy, version of libmongoc. We will rapidly work towards reaching an API/ABI stable library fit for a 1.0.0 release. Libmongoc is Apache licensed so it can be embedded in a multitude of scenarios. The API of 0.90.0 is completely different from the previous versions. We think this allowed us to create a high-quality library that you will enjoy using in your applications. Many outstanding bugs were closed in the process of creating Libbson 0.90.0. So if you had a pet issue, please take a look to see if it was resolved as part of this effort! Thanks, and enjoy developing your applications with libmongoc!
