“This release contains a number of bug fixes, and includes all
Hotfixes to date. It includes the fix for a memory leak that could
occur when accessing SQL data through aliased names, a fix for a
problem with contention between concurrent POST requests and a
number of fixes to improve support for current WebDAV-aware clients
such as Adobe GoLive. Over 60 Collector issues were closed out in
preparing for the 2.2.5 release – thanks to those who submitted
patches and helped to investigate bugs and verify fixes.”

binary – if you are running a source release you should rebuild the
Zope binaries after upgrading or applying a “diff” update….”
