The correct way to get an ad-hoc task to run as the main admin account
is to leave userid as null.
Setting it causes fatal errors if the main admin account is set to
auth: nologin.
This hack was introduced to work around a bug in MySQL 5.6.14 and
MariaDB at the time.
https://bugs.mysql.com/bug.php?id=69882
It was addressed a few months later in 5.6.16, and 5.7.4.
MariaDB merged version 5.6.16 of MySQL's InnoDB engine in MariaDB
10.0.11 and got the patch from there.
Moodle has required MySQL 5.7, and MariaDB 10.2.29 since Moodle 3.11 and
it is therefore safe to remove these hacks for these versions.
* In matching types of questions, sometimes the user does not answer all
questions. We now display "None" in the result report. The answer can
be either correct or incorrect.
* Fix "unknown" answer constant name.
In some places we prevented cache poisoning, in others we did not. We
also did not place any restriction on the minimum value for a revision.
This change introduces a new set of functions for configonly endpoints
which validates the revision numbers passed in. If the revision is
either too old, or too new, it is rejected and the file content is not
cached. The content is still served, but caching headers are not sent,
and any local storage caching is prevented.
The current time is used as the maximum version, with 60 seconds added
to allow for any clock skew between cluster nodes. Previously some
locations used one hour, but there should never be such a large clock
skew on a correctly configured system.

* We need to set a different meetingID when duplicating or importing a
BigBlueButtonBN activity to prevent unwanted sharing of recordings between
meetings.
With the new flow, users can go to the login page from the confirmed page,
and if the user successfully logs in, the user will be directed to the confirmed page.
To avoid that, the confirmed page can only be seen by users who are not logged in.
The Moodle XML export of multiple choice calculated questions was
missing proper escaping of answers. Also the indentation of the
generated xml was off.
