I encountered the following issue in Moodle-Docker. It may be a problem on my side, but I report it as 5.0 regression just to be sure.

Steps to reproduce:

• Prepare a Moodle release 4.5.4 codebase
• Install the Moodle instance so that it can be used
• Enable full debugging, ideally in config.php with

  $CFG->debug = (E_ALL);

• Update the Moodle codebase to Moodle release 5.0+ (as of May 2, commit 69b36a36b4669b2c67a2822cc491194b2da3cedb)
• Run the Moodle upgrade in the GUI

Expected result:

• The Moodle instance is upgraded to Moodle 5.0 without any problems

Actual result:

• When upgrading the Moodle instance, an error is shown during the upgrade:

  The capability 'mod/data:comment' is deprecated. This capability should not be used anymore.

• After reloading the page, another error is shown during the upgrade:

  The capability 'tiny/premium:accesspremium' is deprecated.This capability has been renamedIt will be replaced by 'tiny/premium:use'.

• After reloading the page once more, the upgrade finishes successfully
