* SubGHz: Default custom buttons layout for non standard remotes (for example your remote has broken buttons and transmit only 0xC, now you can use other buttons)
* SubGHz: Fix issues with external module 5v power (now all works automatically, enabling +5v manually not required) (**Only for modules that work with 5v->3.3v converter!!!!!**)
* SubGHz: Option to disable automatic 5v power for external modules - (5v is enabled by default, if you are using module without converter you can set this option to OFF)
* OFW: NFC: Support reading Mifare Classic key B from sector trailer, reading sector with B key where A key can't read block, Nfc Magic app not using NFC folder by default (in file select)
* OFW: Remove ValueMutex -> **Breaking API change, api was changed from 17.x to 18.x**
* OFW: SubGhz: better and more verbose error handling in protocols, stricter CAME validation -> **Breaking API change, api was changed from 16.x to 17.x**
* OFW: iButton system and app refactoring (+new protocols) -> **Breaking API change, api was changed from 15.x to 16.x**
**(this will make your manually copied plugins not work, update them in same way you installed them, or delete `apps` folder and then install firmware, if you using extra pack builds (with `e` in version) all apps in _Extra will be updated automatically)**
**Note: To avoid issues with .dfu, prefer installing using .tgz with qFlipper, web updater or by self update package, all needed assets will be installed**
What means `n` or `e` in - `flipper-z-f7-update-(version)(n / e).tgz` ? - `n` means this build comes without our custom animations, only official flipper animations,
