* If you have a site running on MariaDB / MySQL with many users, you may experience database issues after the upgrade step 2021042100. The upgrade attempts to drop several columns from the user table (after they were converted to new user profile fields - MDL-28452). This typically leads to copying all the rows into a new tablespace and rebuilding all indexes, potentially reaching time-outs and ''"MySQL server has gone away"'' errors. It should be enough and safe to simply re-run the upgrade until the upgrade step 2021042100.01 finishes successfully.
