 ## Main changes
 - SubGHz:
     - Frequency analyzer fixes and improvements:
-        - Enforce int module (like in OFW) usage due to lack of required hardware on external boards (PathIsolate (+rf switch for multiple paths)) and incorrect usage and/or understanding the purpose of frequency analyzer app by users, it should be used only to get frequency of the remote placed around 1-10cm around flipper's left corner
-        - Fix possible GSM mobile towers signal interference by limiting upper frequency to 920mhz max

+**More details on JS changes** (js changelog written by @Willy-JL , thanks!):
+- Non-exhaustive list of changes to help you fix your scripts:
+    - `badusb`:
+      - `setup()`: `mfr_name`, `prod_name`, `layout_path` parameters renamed to `mfrName`, `prodName`, `layoutPath`
+      - effort required to update old scripts using badusb: very minimal
+    - `dialog`:
+      - removed, now replaced by `gui/dialog` and `gui/file_picker` (see below)
+    - `event_loop`:
+      - new module, allows timer functionality, callbacks and event-driven programming, used heavily alongside gpio and gui modules
+    - `gpio`:
+      - fully overhauled, now you `get()` pin instances and perform actions on them like `.init()`
+      - now supports interrupts, callbacks and more cool things
+      - effort required to update old scripts using gpio: moderate
+    - `gui`:
+      - new module, fully overhauled, replaces dialog, keyboard, submenu, textbox modules
+      - higher barrier to entry than older modules (requires usage of `event_loop` and `gui.viewDispatcher`), but much more flexible, powerful and easier to extend
+      - includes all previously available js gui functionality (except `widget`), and also adds `gui/loading` and `gui/empty_screen` views
+      - currently `gui/file_picker` works different than other new view objects, it is a simple `.pickFile()` synchronous function, but this [may change later](https://github.com/flipperdevices/flipperzero-firmware/pull/3961#discussion_r1805579153)
+      - effort required to update old scripts using gui: extensive
+    - `keyboard`:
+      - removed, now replaced by `gui/text_input` and `gui/byte_input` (see above)
+    - `math`:
+      - `is_equal()` renamed to `isEqual()`
+    - `storage`:
+      - fully overhauled, now you `openFile()`s and perform actions on them like `.read()`
+      - now supports many more operations including different open modes, directories and much more
+      - effort required to update old scripts using storage: moderate
+    - `submenu`:
+      - removed, now replaced by `gui/submenu` (see above)
+    - `textbox`:
+      - removed, now replace by `gui/text_box` (see above)
+    - `widget`:
+      - only gui functionality not ported to new gui module, remains unchanged for now but likely to be ported later on
+    - globals:
+      - `__filepath` and `__dirpath` renamed to `__filename` and `__dirname` like in nodejs
+      - `to_string()` renamed and moved to number class as `n.toString()`, now supports optional base parameter
+      - `to_hex_string()` removed, now use `n.toString(16)`
+      - `parse_int()` renamed to `parseInt()`, now supports optional base parameter
+      - `to_upper_case()` and `to_lower_case()` renamed and moved to string class as `s.toUpperCase()` and `s.toLowerCase()`
+      - effort required to update old scripts using these: minimal
+  - Added type definitions (typescript files for type checking in IDE, Flipper does not run typescript)
+  - Documentation is incomplete and deprecated, from now on you should refer to type definitions (`applications/system/js_app/types`), those will always be correct
+  - Type definitions for extra modules we have that OFW doesn't will come later
