Add a note in change log
* **0.35-SNAPSHOT**:
- CI builds with Maven Wrapper to ensure that Maven Wrapper files and configuration are correct ([1450](https://github.com/fabric8io/docker-maven-plugin/issues/1450))
-
+ - Using <external> properties in image configuration disables Docker cache during build ([1455](https://github.com/fabric8io/docker-maven-plugin/issues/1455))
+ - Update documentation to clearly state that `docker.cacheFrom.idx` is a _list_ property and should always be used with a `idx` suffix. With this change, `docker.cacheFrom` (without _idx_) is not considered anymore.
* **0.35.0** (2021-04-04)
- Building 'spring-boot-with-jib' sample fails with NoSuchMethodError ([1384](https://github.com/fabric8io/docker-maven-plugin/issues/1384))
