Moodle 4.2 developer update
This page highlights the important changes that are coming in Moodle 4.2 for developers.
External API
The external_api class, and all related classes have been moved from lib/externallib.php to namespaced classes within the core_external subsystem.
Delayed deprecation
The old class locations have been aliased for backwards compatibility and will emit a deprecation notice in a future release.
If you are writing a Moodle plugin which has a single codebase shared with older versions of Moodle, you should continue to use the old API locations at this time.
The following parts of the external API have been moved to the core_external subsystem.
