So Far this is all I have seen in regards to release notes.
Seems for the Frontend:
V1.12 adds support for broadband communication capability via the Go!Bridge (adds dual communication for cellular and WIFI), Portuguese language, minor UI changes, etc. This update is only for CP, TS1 version is 1.10.
And on the Backend:
New Advanced Remote Commands Now Available for 2GIG
A new firmware release for 2GIG Go!Control Panels will make installation and system maintenance right from your mobile device easier than ever. The new 1.12 firmware delivers more remote capabilities so you can now enjoy:
Put the 2GIG panel in Add or Delete Mode directly from the Dealer Website or MobileTech. When the Remote Add or Delete Mode command is sent, the panel will stay in that Mode until you exit, allowing you to continuously add devices without additional steps in-between.
Improved Z-Wave Network Stability
Perform a remote Rediscovery from the Dealer Website or MobileTech to help assure the stability of the mesh network. Run this when you complete an installation or have recently added, removed, or moved devices in the network. Remote Rediscoveries will take approximately 5 minutes and vary depending on the size and complexity of the network.
Long-Term Tracking and System Performance Diagnosis
With 1.12, you now have the ability to request and analyze diagnostic counters of a Z-Wave network.
These new features will help make your installations more efficient and provide an even smoother customer experience.
