-## Bootloader
-
-Enter the bootloader in 3 ways:
-
-* **Bootmagic reset**: Hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
-* **BootloadHID reset**: Hold down the key connected to the `A0` and `B0` pins on the MCU if it is known (often top left or bottom left) and plug in the keyboard
-* **Physical reset button**: Briefly press the button on the back of the PCB - some may have pads you must short instead
-* **Keycode in layout**: Press the key mapped to `RESET` if it is available

+# QMK Breaking Changes - 2022 February 26 Changelog
+
+## Notable Features :id=notable-features
+
+### Default USB Polling rate now 1kHz ([#15352](https://github.com/qmk/qmk_firmware/pull/15352))
+
+The default USB Polling rate has been aligned across supported platforms to now be 1ms/1kHz.
+
+Something something *Lets go gamers!*
+
+### Split support for pointing devices ([#15304](https://github.com/qmk/qmk_firmware/pull/15304))
+
+Pointing devices can now be shared across a split keyboard with support for a single pointing device or a pointing device on each side.
+
+See the [Pointing Device](feature_pointing_device.md) documentation for further configuration options.
+
+## Changes Requiring User Action :id=changes-requiring-user-action
+
+### Legacy macro and action_function system removed ([#16025](https://github.com/qmk/qmk_firmware/pull/16025))
+
+The long time deprecated `MACRO()` and `action_get_macro` methods have been removed. Where possible, existing usages have been migrated over to core [Macros](feature_macros.md).
+
+### Create a build error if no bootloader is specified ([#16181](https://github.com/qmk/qmk_firmware/pull/16181))
+
+Bootloader configuration is no longer assumed. Keyboards must now set either:
+
+* `BOOTLOADER` within `rules.mk`
+* `bootloader` within `info.json`
+
+### Rename `AdafruitBLE` to `BluefruitLE` ([#16127](https://github.com/qmk/qmk_firmware/pull/16127))
+
+In preparation of future bluetooth work, the `AdafruitBLE` integration has been renamed to allow potential for any other Adafruit BLE products. 
+
+### Updated Keyboard Codebases :id=updated-keyboard-codebases
+
+The following keyboards have had their source moved within QMK:
+

 ### Adafruit BLE SPI Friend
 Currently The only bluetooth chipset supported by QMK is the Adafruit Bluefruit SPI Friend. It's a Nordic nRF51822 based chip running Adafruit's custom firmware. Data is transmitted via Adafruit's SDEP over Hardware SPI. The [Feather 32u4 Bluefruit LE](https://www.adafruit.com/product/2829) is supported as it's an AVR mcu connected via SPI to the Nordic BLE chip with Adafruit firmware. If Building a custom board with the SPI friend it would be easiest to just use the pin selection that the 32u4 feather uses but you can change the pins in the config.h options with the following defines:

 ## Modifier Combos
 If a combo resolves to a Modifier, the window for processing the combo can be extended independently from normal combos. By default, this is disabled but can be enabled with `#define COMBO_MUST_HOLD_MODS`, and the time window can be configured with `#define COMBO_HOLD_TERM 150` (default: `TAPPING_TERM`).

-For each combo, it is possible to configure the time window it has to pressed in, if it needs to be held down, or if it needs to be tapped.
+By defining `COMBO_MUST_PRESS_IN_ORDER` combos only activate when the keys are pressed in the same order as they are defined in the key array.
 
-For example, tap-only combos are useful if any (or all) of the underlying keys is a Mod-Tap or a Layer-Tap key. When you tap the combo, you get the combo result. When you press the combo and hold it down, the combo doesn't actually activate. Instead the keys are processed separately as if the combo wasn't even there.

+You can use between 1 and 4 IC's. Do not specify `DRIVER_ADDR_<N>` define for IC's if not present on your keyboard. The `DRIVER_ADDR_1` default assumes that all Address pins on the controller have been connected to GND. Drivers that have SYNC functionality have the default settings to disable if 1 driver. If more than 1 drivers then `DRIVER_ADDR_1` will be set to Master and the remaiing ones set to Slave.

+#define DRIVER_2_LED_TOTAL 42
+#define DRIVER_LED_TOTAL (DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL)

As an example, `rand() % (DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL)` will give very different results than `rand() % DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL`.
+
+Currently only 4 drivers are supported, but it would be trivial to support for more. Note that using a combination of different drivers is not supported. All drivers must be of the same model.

+ *    |  LED address
+ *    |  | */
+    { 0, CS1_SW1 },
+    { 0, CS2_SW1 },
+    // ...
+}
+```
+
+Where `CSx_SWx` is the location of the LED in the matrix defined by the datasheet. The `driver` is the index of the driver you defined in your `config.h` (`0`, `1`, `2`, or `3` for now).
+
+`ISSI_MANUAL_SCALING` is used to override the Scaling for individual LED's. By default they will be set as per `ISSI_SCAL_LED`. In `config.h` set how many LED's you want to manually set scaling for.
+Eg `#define ISSI_MANUAL_SCALING 3`
+
+Then Define the array listing all the LEDs you want to override in your `<keyboard>.c`:
+
+```c
+const is31_led __flash g_is31_scaling[ISSI_MANUAL_SCALING] = {
+ *   LED Index
+ *   |  Scaling
+ *   |  | */
+    {5, 120},
+    {9, 120},
+    ....
+}
+```
+
+Where LED Index is the position of the LED in the `g_is31_leds` array. The `scaling` value between 0 and 255 to be written to the Scaling Register.

+### PMW 3389 Sensor
+
+To use the PMW 3389 sensor, add this to your `rules.mk`
+
+```make
+POINTING_DEVICE_DRIVER = pmw3389
+```
+
+The PMW 3389 is an SPI driven optical sensor, that uses a built in IR LED for surface tracking.

 ### Custom Driver
 
-If you have a sensor type that isn't supported here, you can manually implement it, by adding these functions (with the correct implementation for your device):
+If you have a sensor type that isn't supported above, a custom option is available by adding the following to your `rules.mk`
+
+```make
+POINTING_DEVICE_DRIVER = custom

As an example, `rand() % (DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL)` will give very different results than `rand() % DRIVER_1_LED_TOTAL + DRIVER_2_LED_TOTAL`.

+

+    ....
+}
+```
+
+Where `CSx_SWx` is the location of the LED in the matrix defined by the datasheet. The `driver` is the index of the driver you defined in your `config.h` (`0`, `1`, `2`, or `3` for now).
+
+`ISSI_MANUAL_SCALING` is used to override the Scaling for individual LED's. By default they will be set as per `ISSI_SCAL_<colour>`. In `config.h` set how many LED's you want to manually set scaling for.

-# Keyboards with AVR Processors
-
-This page describes the support for AVR processors in QMK. AVR processors include the atmega32u4, atmega32u2, at90usb1286, and other processors from Atmel Corporation. AVR processors are 8-bit MCUs that are designed to be easy to work with. The most common AVR processors in keyboards have on-board USB and plenty of GPIO for supporting large keyboard matrices. They are the most popular MCU for use in keyboards today.
-
-If you have not yet you should read the [Keyboard Guidelines](hardware_keyboard_guidelines.md) to get a sense of how keyboards fit into QMK.
-
-## Adding Your AVR Keyboard to QMK
-
-QMK has a number of features to simplify working with AVR keyboards. For most keyboards you don't have to write a single line of code. To get started, run `qmk new-keyboard`:
-
-```
-$ qmk new-keyboard
-Ψ Generating a new QMK keyboard directory
-
-Keyboard Name: mycoolkeeb
-Keyboard Type:
-        1. avr
-        2. ps2avrgb
-Please enter your choice:  [1]
-Your Name: [John Smith]
-Ψ Copying base template files...
-Ψ Copying avr template files...
-Ψ Renaming keyboard.[ch] to mycoolkeeb.[ch]...
-Ψ Replacing %YEAR% with 2021...
-Ψ Replacing %KEYBOARD% with mycoolkeeb...
-Ψ Replacing %YOUR_NAME% with John Smith...
-
-Ψ Created a new keyboard called mycoolkeeb.
-Ψ To start working on things, `cd` into keyboards/mycoolkeeb,
-Ψ or open the directory in your preferred text editor.
-```
-
-This will create all the files needed to support your new keyboard, and populate the settings with default values. Now you just need to customize it for your keyboard.
-
-## `readme.md`
-
-This is where you'll describe your keyboard. Please follow the [Keyboard Readme Template](documentation_templates.md#keyboard-readmemd-template) when writing your `readme.md`. You're encouraged to place an image at the top of your `readme.md`, please use an external service such as [Imgur](https://imgur.com) to host the images.
-
-## `<keyboard>.c`
-
-This is where all the custom logic for your keyboard goes. Many keyboards do not need to put anything at all in here. You can learn more about writing custom logic in [Custom Quantum Functions](custom_quantum_functions.md).
-
-## `<keyboard>.h`
-
-This is the file you define your [Layout Macro(s)](feature_layouts.md) in. At minimum you should have a `#define LAYOUT` for your keyboard that looks something like this:
-
-```c
-#define LAYOUT(          \
-      k00, k01, k02,     \
-      k10,   k11         \
-) {                      \
-    { k00, k01,   k02 }, \
-    { k10, KC_NO, k11 }, \
-}
-```
-
-The first half of the `LAYOUT` pre-processor macro defines the physical arrangement of keys. The second half of the macro defines the matrix the switches are connected to. This allows you to have a physical arrangement of keys that differs from the wiring matrix.
-
-Each of the `k__` variables needs to be unique, and typically they follow the format `k<row><col>`.
-
-The physical matrix (the second half) must have a number of rows equaling `MATRIX_ROWS`, and each row must have exactly `MATRIX_COLS` elements in it. If you do not have this many physical keys you can use `KC_NO` to fill in the blank spots.
-
-## `config.h`
-
-The `config.h` file is where you configure the hardware and feature set for your keyboard. There are a lot of options that can be placed in that file, too many to list there. For a complete overview of available options see the [Config Options](config_options.md) page.
-
-### Hardware Configuration
-
-
-At the top of the `config.h` you'll find USB related settings. These control how your keyboard appears to the Operating System. If you don't have a good reason to change you should leave the `VENDOR_ID` as `0xFEED`. For the `PRODUCT_ID` you should pick a number that is not yet in use.
-
-Do change the `MANUFACTURER` and `PRODUCT` lines to accurately reflect your keyboard.
-
-```c
-#define VENDOR_ID       0xFEED
-#define PRODUCT_ID      0x6060
-#define DEVICE_VER      0x0001
-#define MANUFACTURER    You
-#define PRODUCT         my_awesome_keyboard
-```
-
-?> Windows and macOS will display the `MANUFACTURER` and `PRODUCT` in the list of USB devices. `lsusb` on Linux instead prefers the values in the list maintained by the [USB ID Repository](http://www.linux-usb.org/usb-ids.html). By default, it will only use `MANUFACTURER` and `PRODUCT` if the list does not contain that `VENDOR_ID` / `PRODUCT_ID`. `sudo lsusb -v` will show the values reported by the device, and they are also present in kernel logs after plugging it in.
-
-### Keyboard Matrix Configuration
-
-The next section of the `config.h` file deals with your keyboard's matrix. The first thing you should set is the matrix's size. This is usually, but not always, the same number of rows and columns as the physical key arrangement.
-
-```c
-#define MATRIX_ROWS 2
-#define MATRIX_COLS 3
-```
-
-Once you've defined the size of your matrix you need to define which pins on your MCU are connected to rows and columns. To do so simply specify the names of those pins:
-
-```c
-#define MATRIX_ROW_PINS { D0, D5 }
-#define MATRIX_COL_PINS { F1, F0, B0 }
-#define UNUSED_PINS
-```
-
-The number of `MATRIX_ROW_PINS` entries must be the same as the number you assigned to `MATRIX_ROWS`, and likewise for `MATRIX_COL_PINS` and `MATRIX_COLS`. You do not have to specify `UNUSED_PINS`, but you can if you want to document what pins are open.
-
-Finally, you can specify the direction your diodes point. This can be `COL2ROW` or `ROW2COL`.
-
-```c
-#define DIODE_DIRECTION COL2ROW
-```
-
-#### Direct Pin Matrix
-To configure a keyboard where each switch is connected to a separate pin and ground instead of sharing row and column pins, use `DIRECT_PINS`. The mapping defines the pins of each switch in rows and columns, from left to right. Must conform to the sizes within `MATRIX_ROWS` and `MATRIX_COLS`, use `NO_PIN` to fill in blank spaces. Overrides the behaviour of `DIODE_DIRECTION`, `MATRIX_ROW_PINS` and `MATRIX_COL_PINS`.
-
-```c
-// #define MATRIX_ROW_PINS { D0, D5 }
-// #define MATRIX_COL_PINS { F1, F0, B0 }
-#define DIRECT_PINS { \
-    { F1, E6, B0, B2, B3 }, \
-    { F5, F0, B1, B7, D2 }, \
-    { F6, F7, C7, D5, D3 }, \
-    { B5, C6, B6, NO_PIN, NO_PIN } \
-}
-#define UNUSED_PINS
-
-/* COL2ROW, ROW2COL */
-//#define DIODE_DIRECTION
-```
-
-### Backlight Configuration
-
-QMK supports backlighting on most GPIO pins. A select few of these can be driven by the MCU in hardware. For more details see the [Backlight Documentation](feature_backlight.md).
-
-```c
-#define BACKLIGHT_PIN B7
-#define BACKLIGHT_LEVELS 3
-#define BACKLIGHT_BREATHING
-#define BREATHING_PERIOD 6
-```
-
-### Other Configuration Options
-
-There are a lot of features that can be configured or tuned in `config.h`. You should see the [Config Options](config_options.md) page for more details.
-
-## `rules.mk`
-
-You use the `rules.mk` file to tell QMK what files to build and what features to enable. If you are building around an atmega32u4 you can largely leave these defaults alone. If you are using another MCU you may have to tweak some parameters.
-
-### MCU Options
-
-These options tell the build system what CPU to build for. Be very careful if you change any of these settings, you can render your keyboard inoperable.
-
-```make
-MCU = atmega32u4
-F_CPU = 16000000
-ARCH = AVR8
-F_USB = $(F_CPU)
-OPT_DEFS += -DINTERRUPT_CONTROL_ENDPOINT
-```
-
-### Bootloaders
-
-The bootloader is a special section of your MCU that allows you to upgrade the code stored on the MCU. Think of it like a Rescue Partition for your keyboard. 
-
-#### Teensy Bootloader Example
-
-```make
-BOOTLOADER = halfkay
-```
-
-#### Atmel DFU Loader Example
-
-```make
-BOOTLOADER = atmel-dfu
-```
-
-#### Pro Micro Bootloader Example
-
-```make
-BOOTLOADER = caterina
-```
-
-### Build Options
-
-There are a number of features that can be turned on or off in `rules.mk`. See the [Config Options](config_options.md#feature-options) page for a detailed list and description.

+# Adding Your Keyboard to QMK
+
+This page describes the support for [Compatible Microcontrollers](compatible_microcontrollers.md) in QMK.
+
+If you have not yet you should read the [Keyboard Guidelines](hardware_keyboard_guidelines.md) to get a sense of how keyboards fit into QMK.
+
+
+QMK has a number of features to simplify working with keyboards. For most, you don't have to write a single line of code. To get started, run `qmk new-keyboard`:
+
+```
+$ qmk new-keyboard

+Ψ To start working on things, `cd` into keyboards/mycoolkeeb,
+Ψ or open the directory in your preferred text editor.
+Ψ And build with qmk compile -kb mycoolkeeb -km default.
+```
+
+This will create all the files needed to support your new keyboard, and populate the settings with default values. Now you just need to customize it for your keyboard.
+
+## `readme.md`
+
+This is where you'll describe your keyboard. Please follow the [Keyboard Readme Template](documentation_templates.md#keyboard-readmemd-template) when writing your `readme.md`. You're encouraged to place an image at the top of your `readme.md`, please use an external service such as [Imgur](https://imgur.com) to host the images.
+
+## `info.json`
+
+The `info.json` file is where you configure the hardware and feature set for your keyboard. There are a lot of options that can be placed in that file, too many to list here. For a complete overview of available options see the [Data Driven Configuration Options](reference_info_json.md) page.
+
+### Hardware Configuration
+
+At the top of the `info.json` you'll find USB related settings. These control how your keyboard appears to the Operating System. If you don't have a good reason to change you should leave the `usb.vid` as `0xFEED`. For the `usb.pid` you should pick a number that is not yet in use.
+
+Do change the `manufacturer` and `keyboard_name` lines to accurately reflect your keyboard.
+
+```json
+    "keyboard_name": "my_awesome_keyboard",
+    "maintainer": "You",
+    "usb": {
+        "vid": "0xFEED",
+        "pid": "0x0000",
+        "device_version": "1.0.0"
+    },
+```
+
+?> Windows and macOS will display the `manufacturer` and `keyboard_name` in the list of USB devices. `lsusb` on Linux instead prefers the values in the list maintained by the [USB ID Repository](http://www.linux-usb.org/usb-ids.html). By default, it will only use `manufacturer` and `keyboard_name` if the list does not contain that `usb.vid` / `usb.pid`. `sudo lsusb -v` will show the values reported by the device, and they are also present in kernel logs after plugging it in.
+
+
+### Matrix Configuration
+
+The next section of the `info` file deals with your keyboard's matrix. The first thing you should define is which pins on your MCU are connected to rows and columns. To do so simply specify the names of those pins:
+
+```json
+    "matrix_pins": {
+        "cols": ["C1", "C2", "C3", "C4"],
+        "rows": ["D1", "D2", "D3", "D4"]
+    },
+```
+
+The size of the `matrix_pins.cols` and `matrix_pins.rows` arrays infer the size of the matrix (previously `MATRIX_ROWS` and `MATRIX_COLS`). 
+
+Finally, you can specify the direction your diodes point. This can be `COL2ROW` or `ROW2COL`.
+
+```json
+    "diode_direction": "ROW2COL",
+```
+
+#### Direct Pin Matrix
+To configure a keyboard where each switch is connected to a separate pin and ground instead of sharing row and column pins, use `matrix_pins.direct`. The mapping defines the pins of each switch in rows and columns, from left to right. The size of the `matrix_pins.direct` array infers the size of the matrix. Use `NO_PIN` to fill in blank spaces. Overrides the behaviour of `diode_direction`, `matrix_pins.cols` and `matrix_pins.rows`.
+
+```json
+    "matrix_pins": {
+        "direct": [
+            ["F1", "E6", "B0", "B2", "B3" ],
+            ["F5", "F0", "B1", "B7", "D2" ],
+            ["F6", "F7", "C7", "D5", "D3" ],
+            ["B5", "C6", "B6", "NO_PIN", "NO_PIN"]
+        ]
+    },
+```
+
+### Layout macros
+
+Next is configuring Layout Macro(s). These define the physical arrangement of keys, and its position within the matrix that a switch are connected to. This allows you to have a physical arrangement of keys that differs from the wiring matrix.
+
+```json
+    "layouts": {
+        "LAYOUT_ortho_4x4": {
+            "layout": [
+                { "matrix": [0, 0], "x": 0, "y": 0 },
+                { "matrix": [0, 1], "x": 1, "y": 0 },
+                { "matrix": [0, 2], "x": 2, "y": 0 },
+                { "matrix": [0, 3], "x": 3, "y": 0 },
+                { "matrix": [1, 0], "x": 0, "y": 1 },
+                { "matrix": [1, 1], "x": 1, "y": 1 },
+                { "matrix": [1, 2], "x": 2, "y": 1 },
+                { "matrix": [1, 3], "x": 3, "y": 1 },
+                { "matrix": [2, 0], "x": 0, "y": 2 },
+                { "matrix": [2, 1], "x": 1, "y": 2 },
+                { "matrix": [2, 2], "x": 2, "y": 2 },
+                { "matrix": [2, 3], "x": 3, "y": 2 },
+                { "matrix": [3, 0], "x": 0, "y": 3 },
+                { "matrix": [3, 1], "x": 1, "y": 3 },
+                { "matrix": [3, 2], "x": 2, "y": 3 },
+                { "matrix": [3, 3], "x": 3, "y": 3 }
+            ]
+        }
+    }
+
+```
+
+In the above example, 
+
+* `LAYOUT_ortho_4x4` defines the name of the layout macro
+  * It must conform to [hardware_keyboard_guidelines.md#ltkeyboard_namehgt]
+* `"matrix": [0, 0]` defines the electrical position
+
+## Additional Configuration
+
+There are a lot of features that can be turned on or off, configured or tuned. Some of these have yet to be migrated over to [Data Driven Configuration](data_driven_config.md). The following sections cover the process for when an `info.json` option is unavailable.
+
+### Configuration Options
+
+For available options for `config.h`, you should see the [Config Options](config_options.md) page for more details.
+
+### Build Options
+
+For available options for `rules.mk`, see the [Config Options](config_options.md#feature-options) page for a detailed list and description.
