+
+### Adds
+- Reworked OpenRewrite recipe integration. (#181)
+  - OpenRewriteDeclarativeRecipeAdapter allows to declare SBM action which applies a declarative OR recipe
+  - OpenRewriteNamedRecipeAdapter allows to declare SBM action which applies an OR recipe by name
+- Bumps OpenRewrite to version 7.22.0 (#174)
+
+### Fixes
+- Fix Conditions for Spring Boot 2.4 to 2.5 Upgrade recipes (#133). Thanks @Turbots
