[isabelle-dev] Isabelle2013-2 release

I’m not sure that we need to rush into a new release immediately.

Yes, warn the mailing list, but leave time for other problems to be reported.

Are there options that would reveal instances of this problem?

The situation is quite different today.  There is also an increasing cultural problem, because the very notion of "stable software release" is getting lost in the younger generation. In fact the very term often sounds like an oxymoron now.
