0.8.1 (2010-04-28)
------------------
* Use ZTK instead of Zope 3.4. Updated imports to use new locations instead of BBB.

* Better documentation

* Security proxies are not added outside of interactions. This makes it easier
  to run non-functional unit-tests.

* Functional tests are running normally again.

* Removed automerge mentions in API in preparation for implementing merge
  functionality.

* Implemented variant shortcuts on Topic objects.

* Introduced TopicMap.getScope() method.

* Improved representation objects for <Scope>, <Topic>, <Name>, <Variant> and <Occurrence>.

* Scope.subscopes() now works for single topics and includes the top scope.

* Changed __name__ parameter of TopicMap.createTopic() to __reprname__ to
  better indicate its purpose.

* Fix: Made default ordering of getName, listNames, getOccurrence and
  listOccurrences more deterministic.

* API: Topic.createRole() and Topic.setRole() and used new syntax for specifying
  role types and players.

* Topic.getOccurrence() and Topic.listOccurrences() now use ANY as default datatype.
  It did nor previously filter on datatypes, so no change in behaviour.

* Split test_indexes into test_indexes and test_indexing.

* Added strict parameter to topic.listOccurrences()

* Better mimick a request in the tests

* Made generation of documentation optional

* Removed unplanned dependency on bzrlib and made it optional

* Removed some old unused non-persistent association and roles.

* Replaced ztm.icu and zope.ucol with ztm.collation

* Introduced ITopicFolder so that we can differentiate between regular IFolders
  and ITopics acting as folders.

0.8 (2009-12-15)
----------------
* Events when adding and removing super-subtype relationships. Required by
  ztm.interfacemanager.
  
* Subtle API-change: topic.getOccurrenceValue would return the default value
  for values that evaluates to false. This broke boolean datatypes in
  particular.

* Use ztm.SetReifier and ztm.SetReified permissions instead of
  zope.ModifyContent.

* Extended TypeIndex to keep track of untyped topics.
  
* Recognise supertype-subtype and type-instance associations.

* Split and rewrote the semi-internal topicreferences decorator.

0.6 (in prehistory)
-------------------
* Initial preview release
