Does the ticket author need to update the checksum.ini (via the script) and package-version.txt (plus possibly add a changelog to SPKG.txt) when doing the version bump, or will that be done by the release manager?

[vbraun]

Yes: author does checksum.ini, package-version.txt

No: changelog in SPKG.txt is deprecated

I also had to update the checksum for the libgap spkg. If it works for you, then its a positive review.

[vbraun]

Note that conjugacy classes of SymmetricGroup(8) now need the table of marks (database_gap), the bound was a little bit higher in previous versions. This is not too surprising since Gap rewrote their conjugacy class code. I've simplified examples to SymmetricGroup(7), going to 8 doesn't really test anything that 7 doesn't already cover.

[tscrim]

I agree. Tests pass for me too, so positive review.
