Hi folks,

I'm pleased to announce that the today's upcoming release of the Cygwin
library (version 2.5.2) introduces a license change.  From 2.5.2
onwards, the Cygwin DLL is now available under the GNU LGPL v3, rather
than the former GPLv3.

The official Red Hat announcement:

This change not only allows us to drop the buyout license, it also
allows us to drop the requirement for contributor's to sign a copyright

I'll follow up later today with a description of the new procedure for
contributions (easy!, but now I have to look for releaseing 2.5.2 first.
Stay tuned.
