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