0.19.0 introduces a lot of new exciting changes. See release notes here for more information.

0.19.1 fixes some bugs found in 0.19.0 version.

As long as the database migration doesn’t interfere too much, there should be no downtime or very minimal downtime. If there are any issues, there are an uptime site here and a site status here

EDIT:

Unfortunately, the database migration caused some errors but I fixed it and afterwards the migration had to run for about an hour. Everything seems to work now, but let me know, if there’s anything that doesn’t seem to work.

Note: There has been a significant change to the federation setup, so if there’s anything relating to federation that seems amiss, please let me know.
