## Main changes
- Current API: 87.2
* SubGHz: **Cardin S449 full support** (with Add manually, and all button codes) (**use FSK12K modulation to read the remote**) (closes issues #735 #908) (by @xMasterX and @zero-mega (thanks!))
* SubGHz: Added **new modulation FSK with 12KHz deviation**
* SubGHz: **KingGates Stylo 4k - Add manually and button switch support** + refactoring of encoder
* SubGHz: **Stilmatic - button 9 support** (two buttons hold simulation) (mapped on arrow keys)
* SubGHz: **Counter editor refactoring** (PR #939 | by @Dmitry422)
* SubGHz: **Alutech AT-4N & Nice Flor S turbo speedup** (PR #942 | by @Dmitry422)
* SubGHz: **Sommer fm2 in Add manually now uses FM12K modulation** (Sommer without fm2 tag uses FM476) (try this if regular option doesn't work for you)
* SubGHz: **Sommer - last button code 0x6 support** (mapped on arrow keys)
* SubGHz: Add 390MHz, 430.5MHz to default hopper list (6 elements like in OFW) (works well with Hopper RSSI level set for your enviroment)
* NFC: Handle PPS request in ISO14443-4 layer (by @WillyJL)
* Archive: Allow folders to be pinned (by @WillyJL)
* Apps: Build tag (**9jan2026p2**) - **Check out more Apps updates and fixes by following** [this link](https://github.com/xMasterX/all-the-plugins/commits/dev)
## Other changes
* SubGHz: Rename Sommer(fsk476) to Sommer (Sommer keeloq works better with FM12K) + added backwards compatibility with older saved files
* Docs: Add full list of supported SubGHz protocols and their frequencies/modulations that can be used for reading remotes - [Docs Link](https://github.com/DarkFlippers/unleashed-firmware/blob/dev/documentation/SubGHzSupportedSystems.md)
* Desktop: Show debug status (D) if clock is enabled and debug flag is on (PR #942 | by @Dmitry422)
* NFC: Fix some typos in Type4Tag protocol (by @WillyJL)
* Clangd: Add clangd parameters in IDE agnostic config file (by @WillyJL)

#### Known NFC post-refactor regressions list: 
- Mifare Mini clones reading is broken (original mini working fine) (OFW)
- While reading some EMV capable cards via NFC->Read flipper may crash due to Desfire poller issue, read those cards via Extra actions->Read specific card type->EMV

## **Recommended update option - Web Updater**

### What `e`, ` `, `c` means? What I need to download if I don't want to use Web updater?
What build I should download and what this name means - `flipper-z-f7-update-(version)(e / c).tgz` ? <br>
`flipper-z` = for Flipper Zero device<br>
`f7` = Hardware version - same for all flipper zero devices<br>
`update` = Update package, contains updater, all assets (plugins, IR libs, etc.), and firmware itself<br>
`(version)` = Firmware version<br>
