After almost two months of work since the last version, we finally released one of the biggest releases of all time!

Multiple device connections

Gadgetbridge could traditionally only connect to one device at one moment. That was mostly enough since not many people would need to connect to two smart watches at the same time. But Gadgetbridge has expanded, and there are a lot of non-smartwatch devices supported by now. For example smart headphones with various settings or the Mijia e-paper watch. If you wanted to connect to those devices, you always needed to disconnect your daily driver smart band/watch first. Thanks to Daniel Dakhnod who worked on multiple device connection support for over a month, we finally felt that it was time to merge his branch. We assume there are still some problems and regressions when more than one device is connected at a time - so consider this experimental and please report bugs into our bug tracker.

Vast device improvements

Huami

José Rebelo did a lot of further improvements for Huami devices, most notably tethered GPS support (sending GPS data from the phone to the device after a workout has been started from the band). This is only enabled for the Mi Band 5 right now but it will be expanded to other devices as we test them.

Fossil Hybrid HR

The Fossil Hybrid HR also received a lot of bug fixes and improvements, mainly thanks to code contributed by Arjan Schrijver who also did a lot of work on the Fossil front in the past. One highlight here is definitely the much improved watch app manager which now shows versions and watchface previews. Another great addition is an integration between the Workout app on the watch and OpenTracks - when you start a Workout on the watch, OpenTracks will start a GPS recording of your workout.

Bangle.js

Bangle.js got improvements thanks to multiple contributors. One big new feature is the webview based app-loader for the internet enabled builds. Also, among other changes and fixes, calendar sync and sending emoji as images is supported now.

Other notable changes

There actually have been very many general non-device specific improvements in this release - too much for writing about everything. Refining of the UI and reorganizing some per-device settings, making more formally global settings per-device settings, bug fixes, icons etc.

As we always write:

For all user-facing changes since the previous blog post, check the following list :)
