Plus additional amendments to Fred's original commit:
1. Updating the version numbers
2. Merging the original two-step upgrade below into one for simplicity:
1. Deleting the pictures for groups with hidepicture set to 1; and
2. Dropping the hidepicture field itself.
3. Converted array() usages to the short syntax [].
Without this index every webservice call will do a full table scan
when it tries to validate a token. On a busy site with many tokens
this adds unnecessary load to the database.
This feature adds an admin tool for creating custom licenses.
Now custom licenses can be added and amended in Moodle, and the site
default can be set to a custom license.
Core licenses remain hard-coded and are uneditable, so they will always
require update within Moodle core updates, and maintain their
internationalisation through core language strings.
This also includes fundamental changes to the license API including
the addition of license caching and deprecation of no longer required
admin settings for license management.
The eventtype index will stop full table scans when the Event API
retrieves events for a group or category and there are a large number
of groups or categories so it cannot use the groupid or categoryid
indexes efficiently.
The modulename-instance index will improve the performance of queries
used by activity backup, deletion and visibility changes where all
the events for an individual activity need to be found.
This commit combines several changes:
* Show authentication errors.
* Show more detailed authentication errors
* When the site backpack is different to the user backpack, show a warning
* Do not duplicate the apiversion and backpackurls in each user backpack.
* Do not support different issuer information for each badge with Open Badges v2.
* Add obversion to assertion url
* Combine separate badges upgrade steps and bump the version number.
* Don't show private collections.
* Push the larger image size to backpacks (512x512).
* BADGE_BACKPACKURL is deprecated
* Don't use property alignments, only alignment
Upgrade the support for Open Badges 2 to support a real open badges 2 backpack.
Moodle can only talk to one backpack at a time, so after switching backpacks, users
will have to manually disconnect and then reconnect their backpack to the new one.
This commit combines several changes:
* Split classes into badges namespace
* Publish expiry data with a badge
* Publish badge alignments in badges exported to the backpack.
* Export the criteria for a badge to the backpack.
