In advance of this year’s Summer release of Moodle 2.5, a code freeze is now in place to work through all remaining issues, identify bugs and provide time for documenting and subsequently QA’ing of the core. A recent note from Dan Poltawski, core Moodle Developer highlights the freeze objectives,
Over the next week we will be working our way through the backlog of submitted issues integrated and aim to start 2.5 QA after this is completed. Moodle 2.5 sees the first release with automated behat tests, so we should see some of the QA tests run automatically and we’ll continue to accept new behat tests to help with this effort.
If you are a plugin author, it is probably best to wait until at least next before starting to check your plugin for 2.5 compatibility as this will be a busy week of changes in the codebase.
