After more than 1.5 month, finally a new Gadgetbridge release is ready!

On the new device front we have support for one new Huami device, the Amazfit GTR 3 Pro and another Sony Headphone, the WH-1000XM5.

Mostly contributed by José, who also did the Sony WH-1000XM5 support, we have tons of new features and improvements for various Zepp OS based devices (the newer Huami devices). For example The GTR4/GTS4 devices can now do bluetooth based phone calls though the watch. There is just too much new stuff, so please just read the ChangeLog at the end of this blog post.

For the Fossil/Skagen Hybrids, Arjan finally solved a long standing issue, where the watch asked for a confirmation on every single connection attempt. If you transferred your secret pairing key from one phone to another, this one likely annoyed you - but no longer :)

Arjan also contributed the big new feature for Gadgetbridge 0.74.0: Cached notification. This feature will allow you to get "old" notifications delivered when you come back into range of your phone, after you walked out of range and missed a notification. This feature is still considered experimental, so it need needs to be enabled explicitly.

For other changes please consult the following ChangeLog. Since we did not have a blog post for 0.73.0 make sure to also read it's impressive ChangeLog :)
