- update to 20230125.2
What's New:
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 absl::StrCat() and absl::StrFormat().
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.
Breaking Changes:
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_ANNOTATIONS
can be defined on the compile command-line to temporarily restore these
spellings, but this compatibility macro will be removed in the future.
Known Issues
The Abseil logging library in this release is not a feature-complete
replacement for glog yet. VLOG and DFATAL are examples of features
