The following final deprecations need to be performed in relation to the old participants unified filter, which was replaced by the participants filter and table filtersets in Moodle 3.9 under MDL-68612.

JavaScript
The following can be removed:

• user/amd/src/unified_filter.js
• user/amd/src/unified_filter_datasource.js

Mustache

• user/templates/unified_filter.mustache can be removed.

Renderer

• user/classes/output/unified_filter.php should follow final deprecation procedures as per MDLSITE-6729 (ie be completely removed).

Renderable

• In user/renderer.php, the unified_filter() function only should follow final deprecation procedures (eg throw an exception).

Other related deprecations performed in MDL-68612 are already covered by other general 4.3 final deprecation issues (library functions in MDL-67345, string in MDL-67347).
