+=============
+
+Transitional package to be used with last Gluon v2019.1.x release
+Simply disables the autoupdater for UBNT ERX devices with bad eraseblocks in flash and prefixes the node's name with "#BADBLOCKS".
+This mitigates the issue that these devices would get bricked by an update to Gluon v2020.1 or newer, where the handling of bad eraseblocks has been changed.
