GitLab Patch Release: 16.11.1, 16.10.4, 16.9.6

On April 24, 2024, we released versions 16.11.1, 16.10.4, 16.9.6 for GitLab Community Edition (CE) and Enterprise Edition (EE). These versions contain important bug and security fixes, and we strongly recommend that all GitLab installations be upgraded to one of these versions immediately. GitLab.com is already running the patched version. GitLab releases fixes for vulnerabilities in dedicated patch releases. There are two types of patch releases: scheduled releases, and ad-hoc critical patches for high-severity vulnerabilities. Scheduled releases are released twice a month on the second and fourth Wednesdays. For more information, you can visit our releases handbook and security FAQ. You can see all of GitLab release blog posts here. For security fixes, the issues detailing each vulnerability are made public on our issue tracker 30 days after the release in which they were patched. We are dedicated to ensuring all aspects of GitLab that are exposed to customers or that host customer data are held to the highest security standards. As part of maintaining good security hygiene, it is highly recommended that all customers upgrade to the latest patch release for their supported version. You can read more best practices in securing your GitLab instance in our blog post.
