The 17.0 major release is coming on May 16, 2024! This version brings many exciting improvements to GitLab, but also removes some deprecated features. We are introducing three breaking change windows during which we expect breaking changes to be deployed to GitLab.com. You can read more about it on our blogpost. The first breaking change window begins 2024-04-22 09:00UTC and ends 2024-04-24 22:00UTC.
It looks like my change introducing translations for the MIME info files broke the build because gettext didn't have the rules needed to translate them. The rules are provided by the shared-mime-info.its rule file, which is provided by the shared-mime-info package.
