 ## [Unreleased]
 
+### Changes
+- Generate formatter defaults from version catalog. ([#3045](https://github.com/diffplug/spotless/pull/3045))
+- Bump default `gson` version `2.13.2` -> `2.14.0`. ([#3045](https://github.com/diffplug/spotless/pull/3045))
+- Bump default `zjsonpatch` version `0.4.14` -> `0.4.16`. ([#3045](https://github.com/diffplug/spotless/pull/3045))
+- Bump default `jackson-dataformat-yaml` version `2.14.1` -> `2.20.1`. ([#3045](https://github.com/diffplug/spotless/pull/3045))
+
 ### Fixed
 - `VersionCatalogStep` preserves entries when comments contain unmatched brackets, preserves commas inside quoted strings, and keeps significant line boundaries in multiline entries. ([#3042](https://github.com/diffplug/spotless/pull/3042))
 - `VersionCatalogStep` now reports unfinished entries as lints at their starting line. These fail formatting by default, so upgrading may expose catalog errors that previously caused silent data loss. ([#3042](https://github.com/diffplug/spotless/pull/3042))

+### Changes
+- Generate formatter defaults from version catalog. ([#3045](https://github.com/diffplug/spotless/pull/3045))
+- Bump default `gson` version `2.13.2` -> `2.14.0`. ([#3045](https://github.com/diffplug/spotless/pull/3045))

+- Bump default `jackson-dataformat-yaml` version `2.14.1` -> `2.20.1`. ([#3045](https://github.com/diffplug/spotless/pull/3045))
 
 ### Fixed
 - `versionCatalog()` preserves entries when comments contain unmatched brackets, preserves commas inside quoted strings, and keeps significant line boundaries in multiline entries. ([#3042](https://github.com/diffplug/spotless/pull/3042))
