on GitHub

It is my pleasure to announce the beta release of mongo-c-driver 1.5.0-rc3.

New features and bug fixes:

• MongoDB 3.4 Support
  -- * MaxStalenessMS
  -- * MongoDB Handshake
• 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 command functions accept flexible options as a BSON document:
  -- * 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
• 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.
• mongoc_collection_create_index_with_opts now applies the collection's
  -- write concern if none is specified in "opts"
• 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 seperate 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
• The random number generator used to select servers is now properly seeded.
• 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.

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.
