Before this change the query used an index scan to perform the
export, this could be really expensive on the database.
After the change the the query will use far more efficient joins,
on a large MySQL instance this can take minutes off of the query
time.
In additon the query was returning two columns that are not used
in the function. The layout column was causing the UNION to fail
on Oracle as it cannot compare text columns, removing these
columns from the returned data should further increase
performance further.
This string became obsolete in Moodle 4.0 due to changes in course
navigation. Since then, it has remained unused and can now be safely
removed, as it is unlikely to be needed in the future.
There is a new callback, <modname>_is_branded, which, by default,
returns false. It needs to be implemented by modules that want their
logo to be displayed as it is (so without applying any filter to
colour them based on their main purpose).
The old monocromo.png activity icon files have been removed and
replaced with the new SVG files created by the UX team.

Now that PHP has support for named parameters, and we can use them in
Moodle, we should ditch `$options` arrays and use first-class,
documented, parameters.
Whilst this may seem scary, dumb, overwhelming, please note that you do
not need to supply all args, for example, to change the last parameter
of `format_text` you no longer need to do this:
return \core\container::get(\core\formatting::class)->format_text(
$text,
FORMAT_MOODLE,
$context,
false,
null,
true,
true,
true,
false,
false,
true,
);
Instead you can do:
return \core\container::get(\core\formatting::class)->format_text(
$text,
FORMAT_MOODLE,
$context,
allowid: true,
);
Or better still:
return \core\container::get(\core\formatting::class)->format_text(
text: $text,
format: FORMAT_MOODLE,
context: $context,
allowid: true,
);
This means that we can get defaults in the function signature, improves
our typing, and allows for deprecation and changes to options. It also
sets us up for success in the future.
If a student hides the timer, store that setting in their user
preferences in order to keep it hidden even if they go from one page
to another in a quiz.
