Other information that may be useful (release notes, etc...)

Release notes are here.

Important changes which may directly impact the packaging of this release include:

• MongoDB C Driver 1.29.0 or newer is required.
• External polyfill library support is removed as a breaking change to the build system, API, and ABI.
  • This is the most significant change in this release.
  • This means the default build configuration now uses bsoncxx polyfill implementations for pre-C++17 configurations rather than the Boost or mnmlstc/core libraries.
  • This means Boost and mnmlstc/core are no longer optional dependencies.
• ENABLE_TESTS is now OFF by default.
  • This means test targets are no longer defined by the default build configuration.
  • This means the FetchContent download-and-configure of the Catch2 v3 library and corresponding C++14 or newer compiler support for building tests (both added in the 3.11.0 release) are no longer required by the default build configuration.
  • Building and using the installed libraries still only require C++11 or newer.
• The CMake option MONGOCXX_OVERRIDE_DEFAULT_INSTALL_PREFIX is removed and now implicitly OFF.
  • This means CMake's default install prefix and related paths are now used by default.
• Various deprecated or undocumented features are removed as a breaking change to the API and ABI.

Note: v3.11 will continue to receive bug fixes (as patch releases) for up to one year after the 4.0.0 release.
