After some delays and fine-tuning of the release, next version of Gadgetbridge is now out with whole lot of changes. Interestingly, it is not 0.71 but already 0.71.3 as of the writing of this blog post.

Initial support for Amazfit GTR 3 and SuperCars (Shell Racing Cars)

Initial support for Amazfit GTR 3 was added, which is very similar to GTS 3, and Mi Band 7 see the wiki page here for more information.

@vanous has added support for an entirely new class of devices - a Bluetooth remote controlled car models! If you own a Shell Racing Car, please give it a try ;)

Bye-bye Android 4.4 (KitKat)

Like we announced in our last blog post, Android 5.0 is now the minimum requirement for Gadgetbridge. This allowed us to clean up some code and ugly workarounds. Even the F-Droid client no longer supports Android 4.4, and we were not aware of users who are still on KitKat. Time to move on!

Bye-bye NDK!

@ashimokawa has ported the ECDH C library to pure java, a very straight-forward and simple port, basically fighting with the absence of pointers and unsigned integers was the only real work to do.

No NDK means faster build times and less build dependencies - also for our CI. Last but not least it also makes reproducible builds easier - we are probably already (almost?) there.

Device support improvements

@joserebelo continued with his quest to implement first class support for Zepp OS based devices (MiBand 7, Amazfit GTR 3, GTS 3...) with their activities, sleep and workouts fetching, firmware updates and more.

The Bangle.js team has been improving the Bangle.js device support and capabilities and added the ability to start services via intents, or to wake and unlock the Android device.

Huami devices (MiBands and Amazfits) can now choose whether device preferences as set in Gadgetbridge should be sent to the device on start of each connection which until now has been the case. This new setting can allow to have a watch or a band be configured in the original vendor's app and then connect it to Gadgetbridge, without overwriting settings in the device during the connection. Many other improvements have been added - like improved "Find device", which is now not dependent on the "Do not disturb" setting.

Fossil HR, InfiniTime, Flipper Zero, Mi Band 6... have also gained several improvements, see change log below. Many thanks to @arjan5, @Ganblejs, @dakhnod, @gfwilliams and others for all the contributions!

General app improvements

We have fixed several crashes. One, when opening Gadgetbridge from the notifications and another crash on some older Android versions.

More automation is now possible thanks to new Intents which allow to set device settings or can send information about a device being connected/disconnected. See a dedicated Wiki page for the Intent API.

These have been just the highlights, see more details below.

Many thanks to everyone for their contributions and support!
