GitLab API changes & breaking changes

GitLab announces deprecations continuously but concentrates breaking API changes into its annual major release each May. Detektu diffs the published REST API spec so the bundle of removals never lands unreviewed.

Change model

How GitLab ships changes

The release patterns that shape your integration risk.

GitLab's REST API (v4) evolves additively during the year, with deprecations announced per milestone and removals reserved for major releases like 17.0 and 18.0. That model is friendly, provided you review the deprecation list. In practice, the list is long and mostly irrelevant to any one integration.

Detektu turns the spec diff into per-endpoint findings and matches them against your declared usage, so the yearly removal bundle becomes a short, reviewed list instead of a release-day scramble.

Monitored for you
