GitLab 13 specific changes

Note: When upgrading to a new major version, remember to first check for background migrations.

13.0

Puma becoming default web server instead of Unicorn

Starting with GitLab 13.0, Puma will be the default web server used in omnibus-gitlab based installations. This will be the case for both fresh installations as well as upgrades, unless users have explicitly disabled Puma and enabled Unicorn. Users who have Unicorn configuration are recommended to refer to the docs on how to convert them to Puma ones.

PostgreSQL 11 becoming minimum required version

To upgrade to GitLab 13.0 or later, users must be already running PostgreSQL 11. PostgreSQL 9.6 and 10 have been removed from the package. Follow the documentation on how to upgrade the packaged PostgreSQL server to required version.

13.3

PostgreSQL 12.3 support

PostgreSQL 12.3 is being shipped with the package in addition to 11.7 which is still the default version. Both fresh installs and upgrades will still continue to use 11.7, but users can manually upgrade to 12.3 following the upgrade docs. Note that PostgreSQL 12 is not supported for Geo deployments in GitLab 13.3 and is planned for the 13.4 release.
