v0.6.3

There are currently known regressions:

• using RTS together with the distributed backend database is not working

Added

• Acton now has a apt repository - apt.acton-lang.io [#320]
  • Version tagged releases are automatically uploaded.

Changed

• actonc now uses cc rather than gcc [#303]
• Acton project makefiles now use $(CC) rather than hardcoding cc [#303]
• Acton is now built and tested on debian:bullseye (11, current stable) [#313]

Fixed

• Debian packages now depend on non-dev libraries for utf8proc & protobuf [#315]
• Makefile restructuring [#304] [#307]
  • backend and compiler Makefiles have now been folded into the top level
    Makefile.
  • DAG is more complete and more things can run correctly in parallel.
  • stack / ghc build now uses 4 parallel threads, for some speedup (55 seconds
    -> 35 seconds on an AMD 5950X). Higher parallelism did not improve things
    much further.
  • Avoid declaring actonc as a PHONY target, which causes constant rebuilds,
    not it actually has proper dependencies defined so make can understand when
    there is nothing to do.
• Debian packages now reflect tip version number [#307] [#308]
  • Previously debian packages had the "base version", like 0.6.2, even when
    built as a pre-release build. actonc --version in the package would still
    correctly identify like e.g. 0.6.2.20210924.16.58.23
  • Now the .deb file also contains the complete build info, like
    acton_0.6.2.20210924.16.58.23_amd64.deb
