 #### ⛔ Breaking Changes
 
 * [sampling] Remove support for SAMPLING_TYPE env var and 'static' value ([@yurishkuro](https://github.com/yurishkuro) in [#4735](https://github.com/jaegertracing/jaeger/pull/4735))
+* Use non-root user in built containers ([@nikzayn](https://github.com/nikzayn) in [#4783](https://github.com/jaegertracing/jaeger/pull/4783)) - this change may cause issues with existing installations using Badger storage, because the existing files would be owned by a different user and would not be writeable after Jaeger upgrade. The workaround is to manually chown the files to the new user (uid=10001).
