mongo-c-driver 1.28.0

Announcing 1.28.0 of libbson and libmongoc, the libraries constituting the MongoDB C Driver.

libbson

New features:

• Add bson_validate_with_error_and_offset.

Build Configuration:

• Remove automatic ccache detection and usage (CCache.cmake).
  • Set CMAKE_<LANG>_COMPILER_LAUNCHER to build with ccache.
• Remove MONGO_USE_CCACHE (no longer applicable; see above).

libmongoc

New features:

• Support In-Use Encryption range queries.
• Include insert ID on result of mongoc_collection_insert_one.
• Add new bulk write API mongoc_bulkwrite_t. Requires MongoDB 8.0. Reduces round-trips for mixed writes.

• Add serverMonitoringMode URI option.

Improvements:

• Improve performance of OpenSSL connection creation.
• Improve performance when trace logging is configured (ENABLE_TRACING=ON) but disabled at runtime.
• Prefer FIPS compliant functions for SCRAM-SHA-256 key derivation.
• Remove required slash to delimit options in MongoDB URI (e.g. mongodb://example.com?w=1 parses the same as mongodb://example.com/?w=1).
• Include topology description in server selection timeout errors.

Notes:

• Bump minimum wire protocol version from 6 (MongoDB 3.6) to 7 (MongoDB 4.0).
• Raise required version of libmongocrypt to 1.11.0 to support In-Use Encryption (corresponds to the CMake option: ENABLE_CLIENT_SIDE_ENCRYPTION).

Build Configuration:

• Remove automatic ccache detection and usage (CCache.cmake).
  • Set CMAKE_<LANG>_COMPILER_LAUNCHER to build with ccache.
• Remove MONGO_USE_CCACHE (no longer applicable; see above).

Changed:

• Test and example targets are excluded from the ALL target.
  • All test targets can be built using the mongo_c_driver_tests target.
  • All example targets can be built using the mongo_c_driver_examples target.
• Use #!/usr/bin/env bash instead of #!/bin/sh in uninstall script generated by ENABLE_UNINSTALL=ON.

Deprecated:

• Use of *_hint functions is deprecated in favor of more aptly named *_server_id functions:

  • mongoc_bulk_operation_set_hint is deprecated for mongoc_bulk_operation_set_server_id
  • mongoc_bulk_operation_get_hint is deprecated for mongoc_bulk_operation_get_server_id
  • mongoc_cursor_set_hint is deprecated for mongoc_cursor_set_server_id
  • mongoc_cursor_get_hint is deprecated for mongoc_cursor_get_server_id

• A future minor release plans to drop support for Visual Studio 2013.

• ENABLE_SSL=LIBRESSL is deprecated along with mongoc_stream_tls_libressl_new. Support for LibreSSL may be dropped in a future major release.

• ENABLE_SASL=CYRUS on Windows platforms is deprecated. Support for ENABLE_SASL=CYRUS on Windows may be dropped in a future major release.

  • The associated Windows-only option CYRUS_PLUGIN_PATH_PREFIX is deprecated.
