Looking at the list of “Octave 6.0.9x release candidates” bug reports here:
I see two regressions that could cause code that previously worked to fail now:
bug #58411: cellfun with “ErrorHandler” returns wrong message
bug #48186: delete(allchild(fig)) in a “deletefcn” callback raises error
and one performance regression
bug #58445: significant slow down in stable version for cellfun invocations which use function handles
It would be good to fix the first two, but I don’t expect to fix the performance issue before the release.
Are any of the rest new regressions for 6.1 or have they always been problems? If not, then I would not expect them to block the 6.1 release.
I also have a possible patch for
bug #59304: exist() does not find a class inside @class directory
but I don’t think this is a regression from 5.2.0, so any fix for it could be delayed until we have time for better testing.
