Added:

• instance Monoid a => Monoid (Vec n a)
• instance Text.Printf(Index)
• instance Text.Printf(Signed)
• instance Text.Printf(Unsigned)

Fixed:

• Clash renders incorrect VHDL when GHCs Worker/Wrapper transformation is enabled #1402

• Minor faults in generated HDL when using annotations from Clash.Annotations.SynthesisAttributes

• Cabal installed through Snap (clash.cabal) can now access the internet to fetch pacakges. #1411

• Generated QSys file for altpll incompatible with Quartus CLI (did work in Quartus GUI)

• Clash no longer uses component names that clash with identifiers imported from:

  • IEEE.STD_LOGIC_1164.all
  • IEEE.NUMERIC_STD.all
  • IEEE.MATH_REAL.all
  • std.textio.all

  when generating VHDL. See https://github.com/clash-lang/clash-compiler/issues/1439.
