GitLab Patch Release: 15.5.4

Today we are releasing version 15.5.4 for GitLab Community Edition and Enterprise Edition.

This version resolves a number of regressions and bugs in this month's 15.5 release and prior versions.

GitLab Community Edition and Enterprise Edition

• Add Hashie::Array to allowed YAML serialization classes
• Allow links to be opened from Swagger UI documentations
• Revert Sidekiq default routing rules

Important notes on upgrading

GitLab 15.4.0 introduced a default Sidekiq routing rule that routes all jobs to the default queue. For instances using queue selectors, this will cause performance problems as some Sidekiq processes will be idle.

1. The default routing rule has been reverted in this release (15.5.4), so upgrading to this version or later will return to the previous behavior.

2. If a GitLab instance now listens only to the default queue (which is not currently recommended), it will be required to add this routing rule back in gitlab.rb:

   sidekiq['routing_rules'] = [['*', 'default']]
   

This version does not include any new migrations, and for multi-node deployments, should not require any downtime.

Please be aware that by default the Omnibus packages will stop, run migrations, and start again, no matter how “big” or “small” the upgrade is. This behavior can be changed by adding a /etc/gitlab/skip-auto-reconfigure file, which is only used for updates.
