Abseil LTS 20230125.4
- The Abseil logging library has been released. This library provides facilities for writing short text messages about the status of a program to
stderr, disk files, or other sinks (via an extension API). See the logging library documentation for more information.
- An extension point,
AbslStringify(), allows user-defined types to seamlessly work with Abseil's string formatting functions like
- A library for computing CRC32C checksums has been added.
- Floating-point parsing now uses the Eisel-Lemire algorithm, which provides a significant speed improvement.
- The flags library now provides suggestions for the closest flag(s) in the case of misspelled flags.
- Using CMake to install Abseil now makes the installed artifacts (in particular
absl/base/options.h) reflect the compiled ABI.
- Abseil now 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 legacy spellings of the thread annotation macros/functions (e.g.
GUARDED_BY()) have been removed by default in favor of the
ABSL_prefixed versions (e.g.
ABSL_GUARDED_BY()) due to clashes with other libraries. The compatibility macro
ABSL_LEGACY_THREAD_ANNOTATIONScan be defined on the compile command-line to temporarily restore these spellings, but this compatibility macro will be removed in the future.
- The Abseil logging library in this release is not a feature-complete replacement for glog yet.
