+### New features

+- The Links API collection endpoints now use pagination for improved performance and usability. Ook uses keyset pagination, so look for a Links header with `next`, `prev`, and `first` links. Use these URLs to advance to the next page. The `X-Total-Count` header indicates the total number of items in the collection. Pagination applies to the following endpoints:
+
+  - `GET /ook/links/domains/sdm/schemas`
+  - `GET /ook/links/domains/sdm/schemas/:schema/tables`
+  - `GET /ook/links/domains/sdm/schemas/:schema/tables/:table/columns`
