Release Notes

GoogleTest will not accept patches of new features to the v1.16.x branch.
We recommend building GoogleTest from the latest commit instead.
Exceptional critical bug fixes may be considered.

C++ Language Support

• GoogleTest requires at least C++14 and follows Google's Foundational C++ Support Policy. See this table for a list of currently supported versions compilers, platforms, and build tools.
• The 1.16.x branch will be the last to support C++14. Future development will require at least C++17.

Notable Changes

• Bazel BUILD files now reference repositories by their canonical names from the Bazel Central Registry (google/googletest@cee1ba1). Users still using the old WORKSPACE system may need to use repo_mapping on repositories that still use the old names.
• Testsuite properties as are now exported as XML elements, not attributes (google/googletest@b4aae50).
