The latest changes are now moved into Amos Yuen's new repository (development branch) on Github:
https://raw.githubusercontent.com/amosyuen/hubitat-zemismart-zigbee/development/Zemismart%20Zigbee%20Blind.groovy
The plans are to publish a summary of the changes made in the last weeks into the [RELEASE] Zemismart Zigbee Blind Driver community forum thread and if no issues are reported, the updates will be pushed via Hubitat Package Manager.
