This patch release contains a few bugfixes and one performance improvement fix that will definitely make a difference for instances with many users. It helps when loading the site with a cookie present, which could take a few seconds due to a full table scan when looking for a user matching the cookie token.

Performance

• perf: add index on users.token (#7191) by Nicolas CARPi (3f5ad25) | to speed up searching for a token on big instances with many users also reduce its size: the sha brought nothing to the table: same
  entropy, smaller size. Adjust the column accordingly, too.
