Note: The ER-X/ER-X-SFP/EP-R6 has more limited storage, and in some cases upgrade may fail due to not enough space. If this happens, remove the old backup image first (using "delete system image" command, seeherefor more details) before doing upgrade.
More details can be found in the release notes below. I would like to thank everyone for their participation in the community, as always helping with testing, reporting issues, providing feedback, suggestions! We certainly could not have done it without you Thank you very much!
