Another year has passed, so it must be time for a new z88dk release! And this is the big 2.0.

z88dk Release 2.0 https://github.com/z88dk/z88dk/releases/tag/v2.0

This z88dk 2.0 release is a stable release and is the culmination of thousands of commits (and many hours of work) during this year.

The newly released SDCC 4.0.0 has been incorporated, and is one of the two compilers available.

This release of z88dk also sees support for two new retro processors:

  gbz80: zsdcc, sccz80 and classic now support gbz80 machines
  8080/5: sccz80 and classic now support 8080/5 machines

Support for the following classic and new machine targets has been added:

  Nintendo Gameboy
  Tesla PMD85 (8080)
  CP/M based: Excalibur 64, Sony SMC-70/SMC-777, Sharp X1
  Hübler/Evert-MC, Hübler Grafik-MC, Kramer MC
  Nichibutsu My Vision, Hanimex Pencil II
  Toshiba Pasopia7, Bandai Supervision SV8000, Videoton TVC
  RomWBW HBIOS based machines including Retrobrew and RC2014
  SCZ180 family machines

We've also improved floating point support to provide a (mostly) IEEE-754 compliant math library. Both integrated integer math and floating point math library now use hardware multiply instructions to improve the performance over the standard z80 architecture assembly floating point library by between 4x and 5x. And this from a starting point that is already better than C coded floating point libraries available elsewhere.

Of course, there's also many other fixes and new features across both compilers and both libraries.
