 # Changelog highlights
 
+## 5.0 (candidate)
+
+-   Much smaller .jar size. 70.2 MB -> 7.8 MB.  
+    Keycloakify now detects which of the static resources from the default theme are actually used by your theme and only include those in the .jar.
+-   Build time: The first build is slowed but the subsequent build are faster. Update your CI so that nodes_modules/.cache is not deleted between builds.
+
+### Breaking changes
+
+There are very few breaking changes in this major version.
+
+-   The [`--external-assets` build option has been removed](https://docs.keycloakify.dev/v/v7/build-options#external-assets-deprecated) it was a performance optimization that is no longer relevant now that
+    we have lazy loading.
+
+-   The `usePrepareTemplate` prototype has been changed, you can search and replace:
