The missing version bump caused cache configuration to not be updated,
and the static acceleration cache size was therefore not updated. The
result here was that the static acceleration cache was constantly
emptied leading to an increased page load time.
Previously, a set of calculated quiz statistics would only 'last' for
15 minutes. Then they would be considered invalid and not used.
Now, computed statistics are kept indefinitely. Instead, when a new
batch of values are computed for a particular set of settings, older numbers
for the same settings are deleted first. Therefore,
question_stats_cleanup_task is no more.
This commit will implement the base api for core
communication. This will include the room creation,
room membership, room access url and all associated
api and related interfaces.
Originally implemented as MDL-76702, MDL-76703 and MDL-76705.

Move the fixed assignment removal upgrade code to the end of the upgrade
script as a new upgrade step. Already upgraded sites with mod_assignment
removed should just be able to rerun this without any issues.
The Assignment 2.2 activity module was disabled in 2012 but kept to
enable pre-2.2 backups to be restored and have the assignments
auto-converted to new assignments. After almost 10 years, it's time
to remove it from Moodle core.
These new settings are designed to enchance user privacy surrounding
groups. They allow groups to be configured so that users outside the
group cannot see the group, so that users in the group cannot see each
other, or so that users cannot see the group at all, even if they are in
it. This avoids issues where a group may be assigned based on sensitive
personal information (such as a person requiring special arrangements
due to a disability).
By default, groups are visible to all and available for participation in
activities, which maintains the current behaviour.
For performance, a new cache has been added to track the number of
groups on a course that are not visible to non-members. This allows us
to revert to the existing behaviour if the new features are not being
used at all on a course, and only apply the new visibility conditions if
they are.
Users who have the moodle/course:viewhiddengroups capability should be
concious of exposing hidden groups when showing their screen to other
users. The "Switch role to..." feature can be used to show a course page
on screen without exposing private availability conditions, for example.
The changes cover several specific areas:
* grouplib functions, which most code should use to get lists of groups
and members (this includes the participants page).
* Activities supporting group overrides will not allow overrides for
groups that are hidden from all users.
* Activities supporting separate/visible groups modes will only allow
groups with the new "participation" flag enabled to be selected.
* Group messaging will be disabled for groups where members cannot see
each other, or cannot see the group at all.
