[isabelle-dev] Isabelle2007 release this year

[Makarius]

Dear Isabelle contributors,

the official Isabelle2007 release needs to be finished this year (proof by 
reflexivity).  This means that there are only a few weeks left to commit 
any significant changes.

Counting backwards from a release date as late as December 2007, and 
subtracting some more weeks to let the dust settle down (when even 
seemingly trivial changes should be posponed after the release), this 
leaves essentially only the rest of October to continue the fluctuation in 
the repository to that we've got used so much.

There is no need for a rush to get important last minute features included 
now.  We will try hard to return to more frequent Isabelle releases after 
the Isabelle2007 one (approximately every 6-12 months).
