This file describes API changes in core filter API and plugins,
information provided here is intended especially for developers.

=== 2.7 ===

* Finally filter may use $PAGE and $OUTPUT, yay!
* Old global text caching was removed, each filter is now responsible
  for own caching.

=== 2.6 ===

* filtersettings.php is now deprecated, migrate to standard settings.php

=== 2.5 ===

* legacy_filter emulation was removed
* support for 'mod/*' filters was removed
* use short filter name instead of old path, ex.: 'filter/tex' ---> 'tex'
  in all filter API functions and methods

=== 2.3 ===

* new setup() method added to moodle_text_filter, invoked before
  filtering happens, used to add all the requirements to the page
  (js, css...) and/or other init tasks. See filter/glossary for
  an example using the API (and MDL-32279 for its justification).

=== 2.2 ===

* legacy filters and legacy locations have been deprecated, so any
  old filter should be updated to use the new moodle_text_filter,
  and any filter bundled under mod/xxxx directories be moved to
  /filter/xxxx (MDL-29995). They will stop working completely in
  Moodle 2.3 (MDL-29996). See the glossary or data filters for
  examples of legacy module filters and locations already updated.
