Added

  • Getter for the start_at_operation_time option in mongocxx::v_noabi::options::change_stream.

Changed

  • Bump the minimum required C Driver version to 1.29.0.
  • CMake option ENABLE_TESTS is now OFF by default.
  • Set ENABLE_TESTS=ON to re-enable building test targets.
  • Set BUILD_TESTING=ON to include test targets in the "all" target when ENABLE_TESTS=ON (since 3.9.0, OFF by default).
  • Layout of mongocxx::v_noabi::options::change_stream to support the new optional start_at_operation_time accessor.

Deprecated

    • BSONCXX_POLY_USE_MNMLSTC_SYSTEM
    • BSONCXX_POLY_USE_BOOST
  • Support for CMake option MONGOCXX_OVERRIDE_DEFAULT_INSTALL_PREFIX.
  • MONGOCXX_OVERRIDE_DEFAULT_INSTALL_PREFIX=OFF is now implicit behavior.
  • Redeclarations of bsoncxx::stdx interfaces in the mongocxx::stdx namespace.
  • Use bsoncxx::stdx::optional<T> instead of mongocxx::stdx::optional<T>.
  • Use bsoncxx::stdx::string_view instead of mongocxx::stdx::string_view.
  • Inline namespace macros for bsoncxx and mongocxx namespace: *_INLINE_NAMESPACE_*.
