### Release Notes

GoogleTest will **not** accept patches of new features to the v1.15.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](https://opensource.google/documentation/policies/cplusplus-support).
See [this
table](https://togithub.com/google/oss-policies-info/blob/main/foundational-cxx-support-matrix.md)
for a list of currently supported versions compilers, platforms, and
build tools.

#### Notable Changes

- [Bzlmod](https://bazel.build/external/overview#bzlmod) is now
officially supported (previously it was supported by the community).
Note that it may take several days after the release for it to become
available in the [Bazel Central
Registry](https://registry.bazel.build/modules/googletest).
-   Many bug fixes
