This release:
- partially enables a properly-serialised blitter for the Amiga, mostly replacing the tentative instant blitter of previous releases;
- adds 1mb and 4mb RAM size options for the Atari ST;
- improves support for .ST disk images of non-default geometry;
- resolves a crash on macOS when the app needs to request user provision of ROMs; and
- gives a version number to macOS builds.
