This new release introduces a new subproject called fp for basic
software-emulated floating-point arithmetic, and public-facing CI through
GitHub Actions. It entirely reworks the READMEs and provides numerous new
routines in math/ as well as performance and codegen improvement.
Windows is now supported across AoR and the default config.mk.dist now works
for all platforms out of the box.
This new release also provides several bug fixes and documentation updates.
