Inspire Analytics in core
Formerly a plugin, Inspire Analytics is now available in core, providing detailed descriptive and prescriptive reports to support learners at risk. Feedback welcome.
New filters for user tours
User tours may now be filtered by category, course and course format, making tours target more specific areas of your site.
Convert HTTP embedded content to HTTPS to ensure it works on your HTTPS site with this tool, now available in core..
OAuth2 services trusted email
A useful checkbox gives the option of accepting OAuth2 signups without a confirmation email, useful if your organisation uses Google for its domain.
Manage all Tokens
Along with a new capability, Manage all tokens, a new admin screen displays user tokens with information and the option to delete them.
A clearer site registration page encourages you to register your site, use the mobile app and receive useful updates. Registered sites can share courses via Moodle.net only.
Database entry tagging
'Data records' is now part of the default tag collection, allowing for more possibilities with Managing tags.
Improved Global Search
If Global search is activated,HTML block content may now be searched and if the admin setting "Search all courses" is enabled, then users can search courses they are not enrolled in but are allowed to view.
Farewell Messages block
With enhanced messaging since Moodle 3.2, there's no need for the old Messages block so it's become a plugin.
