0.6

 after_end.register and after_end.unregister must now be passed a
 transaction object rather than a WSGI environment to avoid the
 possibility that the WSGI environment used by a child participating
 in transaction management won't be the same one used by the repoze.tm
 package.

 repoze.tm now inserts a key into the WSGI environment
 ('repoze.tm.active') if it's active in the WSGI pipeline.  An API
 function, repoze.tm:isActive can be called with a single argument,
 the WSGI environment, to check if the middleware is active.

0.5

 Depend on rerolled ZODB 3.7.1 instead of zopelib.

 Add license and copyright, change trove classifiers.

0.4

 Depend on zopelib rather than ZODB 3.8.0b3 distribution, because the
 ZODB distribution pulls in various packages (zope.interface and ZEO
 most notably) that are incompatible with stock Zope 2.10.4 apps and
 older sandboxes.  We'll need to revisit this.

0.3

 Provide limited compatibility for older transaction package versions
 which don't support the 'transaction.isDoomed' API.

0.2

 Provide after_end API for registering callbacks at transaction end.
