This file describes API changes in core filter API and plugins, information provided here is intended especially for developers. === 3.6 === * Although there is no API change that require you to update your filter, if you use the filter_phrases() helper method, you may wish to take advantage of the changes that were made in MDL-47962 to improve performance. Now, instead of having to compute the replacement HTML for each phrase before you construct the filterobject for it. You can instead pass a callback to the filterobject constructor which is only called if the phrase is used. To understand how to use this, see the comment on filterobject::__construct and look at the filter_glossary changes as an example: https://github.com/moodle/moodle/commit/5a8c44d000ecc5669db26aefebe447f688e8f2ce === 3.0 === * New argument $skipfilters to filter_manager::filter_text to allow applying the filters with a given one omitted. * New admin setting class admin_setting_filter_types which can be used if you want to make the disablefilters value in your code configurable. * Methods filter_manager::text_filtering_hash and moodle_text_filter::hash have been deprecated. There were use by the old Moodle filtered text caching system that was removed several releases ago. === 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.
