Sent to CTAN today with 'headlines':
- Internal adjustments ahead of for LuaTeX 0.81 release
- New "setversion" target for l3build
- Allow \tl_replace:Nnn to replace \prg_do_nothing:
- Allow for plain TeX version of \end in regression test support
- Add experimental lazy boolean function
This should also address some issues with the \suppressfontnotfounderror
Please give CTAN 48 h for installation, etc.
