Upgrading plugins

1. Check for changes in core APIs

Read lib/upgrade.txt to check for the deprecations and core API changes, make sure you applied them to your plugin. Note that entries there are not sorted by priority but rather by integration time. Below is the list of upgrade.txt files that contain information about upgrading from Moodle 3.2 to Moodle 3.3 (note that if you upgrade from earlier versions there may be more files):

For the next releases we are thinking about improving the format of upgrade.txt notes, please have your say on policy issue MDL-58879

2. Check for changes in the API of your plugin type

Below is the list of plugin types that had API changes between Moodle 3.2 and 3.3:

3. Check for changes in the depended plugins

If your plugin depends on another plugin or calls methods from another plugin, read upgrade.txt in this plugin directory (if it exists). Below is the list of standard plugins that had changes between Moodle 3.2 and 3.3:

Due to changes in Authentication plugins settings all standard auth plugins were updated: auth_cas, auth_db, auth_email, auth_fc, auth_imap, auth_ldap, auth_manual, auth_mnet, auth_nntp, auth_none, auth_pam, auth_pop3, auth_shibboleth

Other standard plugins that were updated in 3.3: tool_lp, tool_mobile, enrol_ldap, mod_assign, mod_data, mod_feedback, mod_forum, mod_lesson

4. Do a smoke test of your plugin with developer debugging mode

5. Run all behat and phpunit tests
