August 18, 2023

Added support for

- GNU/Hurd
- Older glibc versions
Updated graphics, fixed typos in Doxygen comments (updated docs)
Fixed some MSVC analyzer warnings

2.2.1

July 25, 2023

Many small bug fixes and internal improvements.
Fixed building for IBM AIX using IBM XL C/C++ V16.1.
Fixed building for Haiku using Clang.
Cleaned up all ‑Wmissing‑prototypes ‑Wdouble‑promotion ‑Wfloat‑conversion warnings.
Debug builds now use ‑g3 on most platforms.
Improved the coverage of the test suite.
Added a new thread pool implementation (not yet used by the library).

2.2.0

July 17, 2023

Many new platforms and toolsets are now supported. See the main page for details.
Plugin loader and sample plugin module implemented! In the near future, some standard plugins will be available as part of the library.
Big performance gains through optimization and refactoring.
Much improved support for syslog and added support for macOS' centralized logging facility (os_log). See sir_syslog_dest.
Support for 256‑color and RGB color modes:
Windows got a lot of love, and support for that platform is better than ever
- A Visual Studio 2022 solution can now be found in the msvs directory with both x64 and arm64 configurations
New macros in sir/ansimacros.h that can be used with libsir or anything that writes to stdio (printf, puts, etc.): printf(RED("Oh lawd, something " ULINE("awful") " has happened!\n");
Test suite:
- New and more vigorous tests
- Now supports command‑line arguments:
  - ‑‑list : lists all the available tests
  - ‑‑only: only run the specified tests
  - ‑‑leave‑logs: leave log files behind for examination
  - ‑‑wait : wait for keypress before exiting
  - ‑‑perf : runs the performance benchmark test (normally skipped)
  - ‑‑version: shows the version of libsir the test suite was built with.
Eliminated several bugs and potential memory leaks (Flawfinder, Valgrind, PVS Studio, Clang‑analyzer, Cppcheck)
More specific error codes and better error reporting
New preprocessor defines:
- SIR_ASSERT_ENABLED: if defined, libsir calls assert (note that if ‑DNDEBUG is present, this becomes a NOOP). If not defined and SIR_SELFLOG=1, libsir writes a red message to stderr containing the condition that would have asserted, along with the file, line, and function. This allows for fine‑grain control over assertions.
- SIR_NO_SYSTEM_LOGGERS: if defined, system logger support is completely disabled/compiled out. The entry points still exist, but they will return an error that the feature is disabled or unavailable.
- SIR_NO_PLUGINS: The same as SIR_NO_SYSTEM_LOGGERS, but for the plugin system.
Better and more thorough documentation.

2.1.1

May 17, 2023

Fixed crash on macOS when handling OS errors
Added FreeBSD support
Fixed ‑Wstrict‑prototype, ‑Wformat warnings
Fixed bug in Makefile (make clean was not deleting all intermediate files)
Disallow root/sudo running the test suite; some of the tests depend on file permissions being unavailable.
