This files describes API changes in /totara/topic/* - plugins,
information provided here is intended especially for developers.

=== 19.0 ===

* Topics have been refactored to work a lot more like normal tag collections. The tag collection which topics use
  can be changed to any tag collection. On installation, there is no longer a dedicated "Topics" tag collection, it
  uses the default tag collection instead. The setting $CFG->topics_collection_id is now redundant.
* Hid the topic report source and topic usage source
* Hid 'topic management page' and 'usage of topic page'
* The topic_helper::delete_topic_usage function no longer verifies whether the topic can be deleted, this check should
  be performed by the caller.
