+== Next version in Camel Quarkus master branch

+If there are no substantial commits in the release branch, which need to get merged/cherry-picked to `master`, you can
+perform this step right after creating the release branch. Otherwise, e.g. if there is a Camel upgrade in the release
+branch which is not available on Maven Central yet, it is better to perform this step after the new Camel release is
+available on the Central and after all relevant commits were merged/cherry-picked to `master`.

+While in the release branch we set the `$NEXT_VERSION` to the next micro SNAPSHOT (e.g. when releasing `0.1.0`,
+`$NEXT_VERSION` would be `0.1.1-SNAPSHOT`), in `master`, we typically set the next version to the next minor
+SNAPSHOT (the next minor SNAPSHOT of `0.1.0` is `0.2.0-SNAPSHOT`).
