Release Notes

abseil/abseil-cpp (abseil-cpp)

v20250512.1: Abseil LTS branch, May 2025, Patch 1

Compare Source

Abseil LTS 2025051.1

What's New:

• The polyfill types absl::any, absl::optional, and absl::variant are now aliases for std::any, std::optional, and std::variant in all builds. (Note that the polyfill implementation absl::string_view remains at the present time, but it defaults to being an alias std::string_view in all builds.)
• Added absl::FastTypeId<Type>(), which evaluates at compile-time to a unique id for the passed-in type.
• Added absl::endian and absl::byteswap polyfills (25bce12).

Breaking Changes:

• Abseil now requires at least C++17 and follows Google's Foundational C++ Support Policy. See this table for a list of currently supported versions compilers, platforms, and build tools.
• Nullability template types are deprecated and will be removed in a future release. The macro-style annotations (absl_nonnull, absl_nullable) should be used instead (caf854d).

Known Issues

• None known at this time.

Baseline: bc257a8
Cherry-pick: 76bb243 (Patch 1)

Known Issues

v20250127.1: Abseil LTS branch, January 2025, Patch 1

Compare Source

Abseil LTS 2025012.1

What's New:

• Added support for Bazel 8.0
• Added support for Bazel Platforms for better portability
• Added ABSL_ATTRIBUTE_VIEW and ABSL_ATTRIBUTE_OWNER for diagnosing certain lifetime issues
• Many performance improvements
• A security issue in hash container create/resize has been fixed. Note that the latest patch releases for previous LTS versions also address this issue.

Breaking Changes:

• Bazel BUILD files now reference repositories by their canonical names from the Bazel Central Registry. For example, Abseil is now @abseil-cpp instead of @com_google_absl, and GoogleTest is now @googletest instead of @com_google_googletest. Users still using the old WORKSPACE system may need to use repo_mapping on repositories that still use the old names. See 90a7ba6 for an example.

Other:

• This will be the last release to support C++14. Future releases will require at least C++17.

Known Issues

• None known at this time.
