Note: The ER-X/ER-X-SFP/EP-R6 has more limited storage, and in some cases, an upgrade may fail due to not enough space. If this happens, remove the old backup image first (using "delete system image" command, see here for more details) before doing an upgrade.


More details can be found in the release notes below. Please give it a try if you are interested in the new features/changes to help us test them so that we can get the release out sooner! Thanks very much!
