+# QMK Breaking Changes - 2023 Aug 27 Changelog
+
+## Notable Changes :id=notable-changes
+
+As per last few breaking changes cycles, there have been _a lot_ of behind-the-scenes changes, mainly around migration of configurables into `info.json` files, cleanup of `info.json` files, additional layout definitions for keyboards, adding support for general community layouts to keyboards, as well as addressing technical debt.
+
+One thing to note for this release -- `qmk/qmk_firmware` is no longer accepting PRs for keymaps other than for manufacturer-supported keymaps. User keymap workflow has been documented [here](https://docs.qmk.fm/#/newbs) for several years. This change is to progressively reduce the maintenance burden on the project, and to allow us to focus on the core features of QMK.
+
+Existing user keymaps and userspace areas will likely be relocated/removed in the future -- non-building keymaps and userspace will be first targets, likely during the new breaking changes cycle. We will provide more information on Discord regarding this initiative as it becomes available.
+
+### RGB Matrix optimizations ([#21134](https://github.com/qmk/qmk_firmware/pull/21134), [#21135](https://github.com/qmk/qmk_firmware/pull/21135)) :id=rgb-matrix-optimizations
+
+Most RGB Matrix implementations now check whether or not RGB LED data has changed and skip transmission if it hasn't. This was measured to improve scan frequency in cases of static or infrequently-changing colors.
+
+### Audio optimizations ([#21496](https://github.com/qmk/qmk_firmware/pull/21496), [#21498](https://github.com/qmk/qmk_firmware/pull/21498))
+
+Some audio code relating to "notes" used `double` datatypes, which are implemented in software floating-point for most ARM microcontrollers. This has been changed to use `float` datatypes instead, which are implemented in hardware floating-point on most ARM microcontrollers. This change increases performance as well as reduces the firmware size by significant number of bytes.
+
+AVR sees minimal (if any) benefit -- `double` was interpreted as `float` on AVR anyway.

+
+### Remove encoder in-matrix workaround code ([#20389](https://github.com/qmk/qmk_firmware/pull/20389)) :id=remove-encoder-in-matrix-workaround-code
+
+Some keyboards "hacked" encoder support into spare slots in the key matrix in order to interoperate with VIA. This workaround is no longer necessary, and the code has been removed. If you have a keyboard that uses this workaround, you will need to update your keymap to use the new [Encoder Map](feature_encoders.md#encoder-map) API instead.
+
+### Unicodemap keycodes rename ([#21092](https://github.com/qmk/qmk_firmware/pull/21092)) :id=unicodemap-keycodes-rename
+
+The Unicodemap keycodes have been renamed:
+
+| Old       | New       |
+|-----------|-----------|
+| `X(i)`    | `UM(i)`   |
+| `XP(i,j)` | `UP(i,j)` |
+
+### Remove old OLED API code ([#21651](https://github.com/qmk/qmk_firmware/pull/21651)) :id=remove-old-oled-api-code
+
+Old OLED code using `ssd1306.c` `ssd1306.h`, and `SSD1306OLED` and other similar files have been consolidated to use the standard OLED driver. External user keymaps will need to be updated to use the standard OLED driver accordingly.
+
+### Driver naming consolidation ([#21551](https://github.com/qmk/qmk_firmware/pull/21551), [#21558](https://github.com/qmk/qmk_firmware/pull/21558), [#21580](https://github.com/qmk/qmk_firmware/pull/21580), [#21594](https://github.com/qmk/qmk_firmware/pull/21594), [#21624](https://github.com/qmk/qmk_firmware/pull/21624), [#21710](https://github.com/qmk/qmk_firmware/pull/21710)) :id=driver-naming-consolidation
+
+In most circumstances this won't affect users -- only keyboard designers with currently-unmerged boards. The only users affected are people who have modified existing keyboards in order to add/modify haptics, lighting, or bluetooth -- and only if the base keyboard did not configure them already. Driver naming has been modified to be lowercase.

-
-When both timers are in use for Audio, the backlight PWM cannot use a hardware timer, and will instead be triggered during the matrix scan. In this case, breathing is not supported, and the backlight might flicker, because the PWM computation may not be called with enough timing precision.
-
-#### Hardware PWM Implementation :id=hardware-pwm-implementation
-
-When using the supported pins for backlighting, QMK will use a hardware timer configured to output a PWM signal. This timer will count up to `ICRx` (by default `0xFFFF`) before resetting to 0.
-The desired brightness is calculated and stored in the `OCRxx` register. When the counter reaches this value, the backlight pin will go low, and is pulled high again when the counter resets.
-In this way `OCRxx` essentially controls the duty cycle of the LEDs, and thus the brightness, where `0x0000` is completely off and `0xFFFF` is completely on.
-
-The breathing effect is achieved by registering an interrupt handler for `TIMER1_OVF_vect` that is called whenever the counter resets, roughly 244 times per second.
-In this handler, the value of an incrementing counter is mapped onto a precomputed brightness curve. To turn off breathing, the interrupt handler is simply disabled, and the brightness reset to the level stored in EEPROM.
-
-#### Timer Assisted PWM Implementation :id=timer-assisted-implementation
-
-When `BACKLIGHT_PIN` is not set to a hardware backlight pin, QMK will use a hardware timer configured to trigger software interrupts. This time will count up to `ICRx` (by default `0xFFFF`) before resetting to 0.
-When resetting to 0, the CPU will fire an OVF (overflow) interrupt that will turn the LEDs on, starting the duty cycle.
-The desired brightness is calculated and stored in the `OCRxx` register. When the counter reaches this value, the CPU will fire a Compare Output match interrupt, which will turn the LEDs off.
-In this way `OCRxx` essentially controls the duty cycle of the LEDs, and thus the brightness, where `0x0000` is completely off and `0xFFFF` is completely on.
-
-The breathing effect is the same as in the hardware PWM implementation.
-
-### ARM Driver :id=arm-configuration
-
-While still in its early stages, ARM backlight support aims to eventually have feature parity with AVR. The `pwm` driver is configured by default, however the equivalent setting within `rules.mk` would be:
-
-```make
-BACKLIGHT_DRIVER = pwm
-```
-
-#### ChibiOS Configuration :id=arm-configuration

-The following `#define`s apply only to ARM-based keyboards:
-

-|`BACKLIGHT_PAL_MODE`   |`2`    |The pin alternative function to use|
-
-See the ST datasheet for your particular MCU to determine these values. Unless you are designing your own keyboard, you generally should not need to change them.

-#### Multiple Backlight Pins :id=multiple-backlight-pins
+### Multiple Backlight Pins :id=multiple-backlight-pins
 
 Most keyboards have only one backlight pin which controls all backlight LEDs (especially if the backlight is connected to a hardware PWM pin).
-In software PWM, it is possible to define multiple backlight pins, which will be turned on and off at the same time during the PWM duty cycle.
+The `timer` and `software` drivers allow you to define multiple backlight pins, which will be turned on and off at the same time during the PWM duty cycle.
 
 This feature allows to set, for instance, the Caps Lock LED's (or any other controllable LED) brightness at the same level as the other LEDs of the backlight. This is useful if you have mapped Control in place of Caps Lock and you need the Caps Lock LED to be part of the backlight instead of being activated when Caps Lock is on, as it is usually wired to a separate pin from the backlight.
 
-To activate multiple backlight pins, add something like this to your `config.h`, instead of `BACKLIGHT_PIN`:

+
+### Timer Driver :id=timer-driver
+
+This driver is similar to the PWM driver, but instead of directly configuring the pin to output a PWM signal, an interrupt handler is attached to the timer to turn the pin on and off as appropriate.
+
+```make
+BACKLIGHT_DRIVER = timer
+```
+
+### Software Driver :id=software-driver
+
+In this mode, PWM is "emulated" while running other keyboard tasks. It offers maximum hardware compatibility without extra platform configuration. However, breathing is not supported, and the backlight can flicker when the keyboard is busy.

 ## Example Schematic
 
+Since the MCU can only supply so much current to its GPIO pins, instead of powering the backlight directly from the MCU, the backlight pin is connected to a transistor or MOSFET that switches the power to the LEDs.
+
 In this typical example, the backlight LEDs are all connected in parallel towards an N-channel MOSFET. Its gate pin is wired to one of the microcontroller's GPIO pins through a 470Ω resistor to avoid ringing.
 A pulldown resistor is also placed between the gate pin and ground to keep it at a defined state when it is not otherwise being driven by the MCU.
 The values of these resistors are not critical - see [this Electronics StackExchange question](https://electronics.stackexchange.com/q/68748) for more information.

 Linear resonant actuators (LRA, also know as a linear vibrator) works different from a ERM. A LRA has a weight and magnet suspended by springs and a voice coil.

 ## Difference to Combos :id=difference-to-combos
 
 Note that key overrides are very different from [combos](https://docs.qmk.fm/#/feature_combo). Combos require that you press down several keys almost _at the same time_ and can work with any combination of non-modifier keys. Key overrides work like keyboard shortcuts (e.g. `ctrl` + `z`): They take combinations of _multiple_ modifiers and _one_ non-modifier key to then perform some custom action. Key overrides are implemented with much care to behave just like normal keyboard shortcuts would in regards to the order of pressed keys, timing, and interacton with other pressed keys. There are a number of optional settings that can be used to really fine-tune the behavior of each key override as well. Using key overrides also does not delay key input for regular key presses, which inherently happens in combos and may be undesirable.
+
+## Solution to the problem of flashing modifiers :id=neutralize-flashing-modifiers
+
+If the programs you use bind an action to taps of modifier keys (e.g. tapping left GUI to bring up the applications menu or tapping left Alt to focus the menu bar), you may find that using key overrides with suppressed mods falsely triggers those actions. To counteract this, you can define a `DUMMY_MOD_NEUTRALIZER_KEYCODE` in `config.h` that will get sent in between the register and unregister events of a suppressed modifier. That way, the programs on your computer will no longer interpret the mod suppression induced by key overrides as a lone tap of a modifier key and will thus not falsely trigger the undesired action.
+
+Naturally, for this technique to be effective, you must choose a `DUMMY_MOD_NEUTRALIZER_KEYCODE` for which no keyboard shortcuts are bound to. Recommended values are: `KC_RIGHT_CTRL` or `KC_F18`. 
+Please note that `DUMMY_MOD_NEUTRALIZER_KEYCODE` must be a basic, unmodified, HID keycode so values like `KC_NO`, `KC_TRANSPARENT` or `KC_PIPE` aka `S(KC_BACKSLASH)` are not permitted.
+
+By default, only left Alt and left GUI are neutralized. If you want to change the list of applicable modifier masks, use the following in your `config.h`:
+
+```c
+#define MODS_TO_NEUTRALIZE { <mod_mask_1>, <mod_mask_2>, ... }
+```
+
+Examples:
+
+```c
+#define DUMMY_MOD_NEUTRALIZER_KEYCODE KC_RIGHT_CTRL
+
+// Neutralize left alt and left GUI (Default value)
+#define MODS_TO_NEUTRALIZE { MOD_BIT(KC_LEFT_ALT), MOD_BIT(KC_LEFT_GUI) }
+
+// Neutralize left alt, left GUI, right GUI and left Control+Shift
+#define MODS_TO_NEUTRALIZE { MOD_BIT(KC_LEFT_ALT), MOD_BIT(KC_LEFT_GUI), MOD_BIT(KC_RIGHT_GUI), MOD_BIT(KC_LEFT_CTRL)|MOD_BIT(KC_LEFT_SHIFT) }
+```
+
+!> Do not use `MOD_xxx` constants like `MOD_LSFT` or `MOD_RALT`, since they're 5-bit packed bit-arrays while `MODS_TO_NEUTRALIZE` expects a list of 8-bit packed bit-arrays. Use `MOD_BIT(<kc>)` or `MOD_MASK_xxx` instead.

 * The smoothness of the cursor movement depends on the `MOUSEKEY_INTERVAL` setting. The shorter the interval is set the smoother the movement will be.  Setting the value too low makes the cursor unresponsive.  Lower settings are possible if the micro processor is fast enough.

+The Raw HID feature allows for bidirectional communication between QMK and the host computer over an HID interface. This has many potential use cases, such as switching keymaps on the fly or sending useful metrics like CPU/RAM usage.
 
-There are two main components to getting raw HID working with your keyboard.
+In order to communicate with the keyboard using this feature, you will need to write a program that runs on the host. As such, some basic programming skills are required - more if you intend to implement complex behaviour.
 
-## Keyboard firmware
+## Usage :id=usage

-In your `rules.mk` add:
+Add the following to your `rules.mk`:
 
 ```make
 RAW_ENABLE = yes

+## Basic Configuration :id=basic-configuration
+
+By default, the HID Usage Page and Usage ID for the Raw HID interface are `0xFF60` and `0x61`. However, they can be changed if necessary by adding the following to your `config.h`:
+
+|Define          |Default |Description                            |

+|`RAW_USAGE_ID`  |`0x61`  |The usage ID of the Raw HID interface  |
+
+## Sending Data to the Keyboard :id=sending-data-to-the-keyboard
+
+To send data to the keyboard, you must first find a library for communicating with HID devices in the programming language of your choice. Here are some examples:
+
+* **Node.js:** [node-hid](https://github.com/node-hid/node-hid)
+* **C/C++:** [hidapi](https://github.com/libusb/hidapi)
+* **Java:** [purejavahidapi](https://github.com/nyholku/purejavahidapi) and [hid4java](https://github.com/gary-rowe/hid4java)
+* **Python:** [pyhidapi](https://pypi.org/project/hid/)
+
+Please refer to these libraries' own documentation for instructions on usage. Remember to close the device once you are finished with it!
+
+Next, you will need to know the USB Vendor and Product IDs of the device. These can easily be found by looking at your keyboard's `info.json`, under the `usb` object (alternatively, you can also use Device Manager on Windows, System Information on macOS, or `lsusb` on Linux). For example, the Vendor ID for the Planck Rev 6 is `0x03A8`, and the Product ID is `0xA4F9`.
+
+It's also a good idea to narrow down the list of potential HID devices the library may give you by filtering on the usage page and usage ID, to avoid accidentally opening the interface on the same device for the keyboard, or mouse, or media keys, etc.
+
+Once you are able to open the HID device and send reports to it, it's time to handle them on the keyboard side. Implement the following function in your `keymap.c` and start coding:
 
 ```c
 void raw_hid_receive(uint8_t *data, uint8_t length) {
-    // Your code goes here. data is the packet received from host.
+    // Your code goes here
+    // `data` is a pointer to the buffer containing the received HID report
+    // `length` is the length of the report - always `RAW_EPSIZE`
 }
 ```
 
-The `"raw_hid.h"` header also declares `void raw_hid_send(uint8_t *data, uint8_t length);` which allows sending packets from keyboard to host. As an example, it can also be used for debugging when building your host application by returning all data back to the host.
+!> Because the HID specification does not support variable length reports, all reports in both directions must be exactly `RAW_EPSIZE` (currently 32) bytes long, regardless of actual payload length. However, variable length payloads can potentially be implemented on top of this by creating your own data structure that may span multiple reports.
+
+## Receiving Data from the Keyboard :id=receiving-data-from-the-keyboard
+
+If you need the keyboard to send data back to the host, simply call the `raw_hid_send()` function. It requires two arguments - a pointer to a 32-byte buffer containing the data you wish to send, and the length (which should always be `RAW_EPSIZE`).
+
+The received report can then be handled in whichever way your HID library provides.
+
+## Simple Example :id=simple-example
+
+The following example reads the first byte of the received report from the host, and if it is an ASCII "A", responds with "B". `memset()` is used to fill the response buffer (which could still contain the previous response) with null bytes.
 
 ```c
 void raw_hid_receive(uint8_t *data, uint8_t length) {
-    raw_hid_send(data, length);
+    uint8_t response[length];
+    memset(response, 0, length);
+    response[0] = 'B';
+
+    if(data[0] == 'A') {
+        raw_hid_send(response, length);
+    }
 }
 ```
 
-These two functions send and receive packets of length `RAW_EPSIZE` bytes to and from the host (32 on LUFA/ChibiOS/V-USB, 64 on ATSAM).
+On the host side (here we are using Python and the `pyhidapi` library), the HID device is opened by enumerating the interfaces on the USB device, then filtering on the usage page and usage ID. Then, a report containing a single ASCII "A" (hex `0x41`) is constructed and sent.
 
-Make sure to flash raw enabled firmware before proceeding with working on the host side.
+For demonstration purposes, the manufacturer and product strings of the device, along with the request and response, are also printed.
 
-## Host (Windows/macOS/Linux)
+```python
+import sys
+import hid
 
-This is the more complicated part as it will require some digging.
+vendor_id     = 0x4335
+product_id    = 0x0002
 
-To connect your host computer to your keyboard with raw HID you need four pieces of information about your keyboard:

-### Building your host

-You can build your host using any language that has an available HID implementation library if you don't wish to make your own. The ones we know of for popular languages are:
+def send_raw_report(data):
+    interface = get_raw_hid_interface()
 
-* Node: [node-hid](https://github.com/node-hid/node-hid).
-* C: [hidapi](https://github.com/libusb/hidapi).
-* Java: [purejavahidapi](https://github.com/nyholku/purejavahidapi) and [hid4java](https://github.com/gary-rowe/hid4java).
-* Python: [pyhidapi](https://pypi.org/project/hid/).
+    if interface is None:
+        print("No device found")
+        sys.exit(1)
 
-This is not an exhaustive cross-platform list but should get you started. There are no special requirements for using raw HID so any HID library should work.
+    request_data = [0x00] * (report_length + 1) # First byte is Report ID
+    request_data[1:len(data) + 1] = data
+    request_report = bytes(request_data)
 
-Now that you have all four pieces of information required to open HID interface to your keyboard. All you need to do is use your library's available functions to open the device with its ID parameters.
+    print("Request:")
+    print(request_report)
 
-Note that Vendor ID and Product ID are not actually required to open the device. They are used only to filter to a specific device out of the many HID devices you have plugged in. Many libraries will give you the option to open the device using Product Name or Manufacturer Name instead, `node-hid` being a prime example. This will create issues for devices with builtin USB Hub or any extra HID interfaces where you will have multiple interfaces with the same name or from the same manufacturer. The Vendor ID together with Product ID create a unique designation to a single interface and will not exhibit this problem. Therefore, even if your library doesn't require you to, it is best to use them to avoid issues.
-Unlike Vendor ID and Product ID though, Usage Page and Usage are necessary for successful communication.
+    try:
+        interface.write(request_report)
 
-It should go without saying that regardless of the library you're using, you should always make sure to close the interface when finished. Depending on the operating system and your particular environment there may be issues connecting to it again afterwards with another client or another instance of the same client if it's not explicitly closed.
+        response_report = interface.read(report_length, timeout=1000)
+
+        print("Response:")
+        print(response_report)
+    finally:
+        interface.close()

-# Unicode Support
+# Unicode :id=unicode
 
-Unicode characters can be input straight from your keyboard! There are some limitations, however.
+With a little help from your OS, practically any Unicode character can be input using your keyboard.
 
-In order to enable Unicode support on your keyboard, you will need to do the following:
+## Caveats :id=caveats
 
-1. Choose one of three supported Unicode implementations: [Basic Unicode](#basic-unicode), [Unicode Map](#unicode-map), [UCIS](#ucis).
-2. Find which [input mode](#input-modes) is the best match for your operating system and setup.
-3. [Set](#setting-the-input-mode) the appropriate input mode (or modes) in your configuration.
-4. Add Unicode keycodes to your keymap.
+There are some limitations to this feature. Because there is no "standard" method of Unicode input across all operating systems, each of them require their own setup process on both the host *and* in the firmware, which may involve installation of additional software. This also means Unicode input will not "just work" when the keyboard is plugged into another device.
 
+## Usage :id=usage
 
-## 1. Methods :id=methods
+The core Unicode API can be used purely programmatically. However, there are also additional subsystems which build on top of it and come with keycodes to make things easier. See below for more details.
 
-QMK supports three different methods for enabling Unicode input and adding Unicode characters to your keymap. Each has its pros and cons in terms of flexibility and ease of use. Choose the one that best fits your use case.
+Add the following to your keymap's `rules.mk`:
 
-The Basic method should be enough for most users. However, if you need a wider range of supported characters (including emoji, rare symbols etc.), you should use Unicode Map.
+```make
+UNICODE_COMMON = yes
+```
 
-<br>
+## Basic Configuration :id=basic-configuration
 
-### 1.1. Basic Unicode :id=basic-unicode
+Add the following to your `config.h`:
 
-The easiest to use method, albeit somewhat limited. It stores Unicode characters as keycodes in the keymap itself, so it only supports code points up to `0x7FFF`. This covers characters for most modern languages (including East Asian), as well as symbols, but it doesn't cover emoji.

+## Input Subsystems :id=input-subsystems
+
+Each of these subsystems have their own pros and cons in terms of flexibility and ease of use. Choose the one that best fits your needs.
+
+<!-- tabs:start -->
+
+### ** Basic **
+
+This is the easiest to use, albeit somewhat limited. It supports code points up to `U+7FFF`, which covers characters for most modern languages (including East Asian), as well as many symbols, but does not include emoji.
+
+To enable Basic Unicode, add the following to your `rules.mk`:
 
 ```make
 UNICODE_ENABLE = yes
 ```
 
-Then add `UC(c)` keycodes to your keymap, where _c_ is the code point of the desired character (preferably in hexadecimal, up to 4 digits long). For example, `UC(0x40B)` will output [Ћ](https://unicode-table.com/en/040B/), and `UC(0x30C4)` will output [ツ](https://unicode-table.com/en/30C4).
+You can then add `UC(c)` keycodes to your keymap, where *c* is the code point of the desired character (in hexadecimal - the `U+` prefix will not work). For example, `UC(0x40B)` will output [Ћ](https://unicode-table.com/en/040B/), and `UC(0x30C4)` will output [ツ](https://unicode-table.com/en/30C4).
 
-<br>
+### ** Unicode Map **
 
-### 1.2. Unicode Map :id=unicode-map
+Unicode Map supports all possible code points (up to `U+10FFFF`). Here, the code points are stored in a separate mapping table (which may contain at most 16,384 entries), instead of directly in the keymap.
 
-In addition to standard character ranges, this method also covers emoji, ancient scripts, rare symbols etc. In fact, all possible code points (up to `0x10FFFF`) are supported. Here, Unicode characters are stored in a separate mapping table. You need to maintain a `unicode_map` array in your keymap file, which may contain at most 16384 entries.
-
-Add the following to your `rules.mk`:
+To enable Unicode Map, add the following to your `rules.mk`:
 
 ```make
 UNICODEMAP_ENABLE = yes
 ```
 
-Then add `X(i)` keycodes to your keymap, where _i_ is the desired character's index in the mapping table. This can be a numeric value, but it's recommended to keep the indices in an enum and access them by name.
+Then, you will need to create a mapping table in your `keymap.c`, and (optionally) an enum for naming the array indices, like so:
 
 ```c
 enum unicode_names {
@@ -51,242 +80,373 @@ enum unicode_names {
     SNEK
 };

     [IRONY] = 0x2E2E,  // ⸮
     [SNEK]  = 0x1F40D, // 🐍
 };
 ```
 
-Then you can use `X(BANG)`, `X(SNEK)` etc. in your keymap.
+Finally, add `UM(i)` keycodes to your keymap, where *i* is an index into the `unicode_map[]` array. If you defined the enum above, you can use those names instead, for example `UM(BANG)` or `UM(SNEK)`.
 
-#### Lower and Upper Case
+#### Lower and Upper Case Pairs :id=unicodemap-pairs
 
-Characters often come in lower and upper case pairs, such as å and Å. To make inputting these characters easier, you can use `XP(i, j)` in your keymap, where _i_ and _j_ are the mapping table indices of the lower and upper case character, respectively. If you're holding down Shift or have Caps Lock turned on when you press the key, the second (upper case) character will be inserted; otherwise, the first (lower case) version will appear.
+Some writing systems have lowercase and uppercase variants of each character, such as å and Å. To make inputting these characters easier, you can use the `UP(i, j)` keycode in your keymap, where *i* and *j* are the mapping table indices of the lowercase and uppercase characters, respectively. If you're holding down Shift or have Caps Lock turned on when you press the key, the uppercase character will be inserted; otherwise, the lowercase character will be inserted.
 
-This is most useful when creating a keymap for an international layout with special characters. Instead of having to put the lower and upper case versions of a character on separate keys, you can have them both on the same key by using `XP()`. This helps blend Unicode keys in with regular alphas.
+```c
+const uint32_t PROGMEM unicode_map[] = {
+    [AE_LOWER] = 0x00E6,  // æ
+    [AE_UPPER] = 0x00C6,  // Æ
+};
+```
 
-Due to keycode size constraints, _i_ and _j_ can each only refer to one of the first 128 characters in your `unicode_map`. In other words, 0 ≤ _i_ ≤ 127 and 0 ≤ _j_ ≤ 127. This is enough for most use cases, but if you'd like to customize the index calculation, you can override the [`unicodemap_index()`](https://github.com/qmk/qmk_firmware/blob/71f640d47ee12c862c798e1f56392853c7b1c1a8/quantum/process_keycode/process_unicodemap.c#L36) function. This also allows you to, say, check Ctrl instead of Shift/Caps.

 ```c
 const ucis_symbol_t ucis_symbol_table[] = UCIS_TABLE(
     UCIS_SYM("poop", 0x1F4A9),                // 💩
     UCIS_SYM("rofl", 0x1F923),                // 🤣
-    UCIS_SYM("cuba", 0x1F1E8, 0x1F1FA),       // 🇨🇺
+    UCIS_SYM("ukr", 0x1F1FA, 0x1F1E6),        // 🇺🇦
     UCIS_SYM("look", 0x0CA0, 0x005F, 0x0CA0)  // ಠ_ಠ
 );
 ```
 
-By default, each table entry may be up to 3 code points long. This number can be changed by adding `#define UCIS_MAX_CODE_POINTS n` to your `config.h` file.
+By default, each table entry may be up to three code points long. This can be changed by adding `#define UCIS_MAX_CODE_POINTS n` to your keymap's `config.h`.
 
-To use UCIS input, call `ucis_start()`. Then, type the mnemonic for the character (such as "rofl") and hit Space, Enter or Esc. QMK should erase the "rofl" text and insert the laughing emoji.
+To invoke UCIS input, the `ucis_start()` function must first be called (for example, in a custom "Unicode" keycode). Then, type the mnemonic for the mapping table entry (such as "rofl"), and hit Space or Enter. The "rofl" text will be backspaced and the emoji inserted.
 
-#### Customization
+<!-- tabs:end -->
 
-There are several functions that you can define in your keymap to customize the functionality of this feature.
+## Input Modes :id=input-modes
 
-* `void ucis_start_user(void)` – This runs when you call the "start" function, and can be used to provide feedback. By default, it types out a keyboard emoji.
-* `void ucis_success(uint8_t symbol_index)` – This runs when the input has matched something and has completed. By default, it doesn't do anything.
-* `void ucis_symbol_fallback (void)` – This runs when the input doesn't match anything. By default, it falls back to trying that input as a Unicode code.
+Unicode input works by typing a sequence of characters, similar to a macro. However, since this sequence depends on your OS, you will need to prepare both your host machine and QMK to recognise and send the correct Unicode input sequences respectively.
 
-You can find the default implementations of these functions in [`process_ucis.c`](https://github.com/qmk/qmk_firmware/blob/master/quantum/process_keycode/process_ucis.c).
-
-
-## 2. Input Modes :id=input-modes
-
-Unicode input in QMK works by inputting a sequence of characters to the OS, sort of like a macro. Unfortunately, the way this is done differs for each platform. Specifically, each platform requires a different combination of keys to trigger Unicode input. Therefore, a corresponding input mode has to be set in QMK.
-
-The following input modes are available:
-
-* **`UNICODE_MODE_MACOS`**: macOS built-in Unicode hex input. Supports code points up to `0x10FFFF` (all possible code points).
-
-  To enable, go to _System Preferences > Keyboard > Input Sources_, add _Unicode Hex Input_ to the list (it's under _Other_), then activate it from the input dropdown in the Menu Bar.
-  By default, this mode uses the left Option key (`KC_LALT`) for Unicode input, but this can be changed by defining [`UNICODE_KEY_MAC`](#input-key-configuration) with a different keycode.
-
-  !> Using the _Unicode Hex Input_ input source may disable some Option-based shortcuts, such as Option+Left and Option+Right.
-
-* **`UNICODE_MODE_LINUX`**: Linux built-in IBus Unicode input. Supports code points up to `0x10FFFF` (all possible code points).
-
-  Enabled by default and works almost anywhere on IBus-enabled distros. Without IBus, this mode works under GTK apps, but rarely anywhere else.
-  By default, this mode uses Ctrl+Shift+U (`LCTL(LSFT(KC_U))`) to start Unicode input, but this can be changed by defining [`UNICODE_KEY_LNX`](#input-key-configuration) with a different keycode. This might be required for IBus versions ≥1.5.15, where Ctrl+Shift+U behavior is consolidated into Ctrl+Shift+E.
-
-  Users who wish support in non-GTK apps without IBus may need to resort to a more indirect method, such as creating a custom keyboard layout ([more on this method](#custom-linux-layout)).
-
-* **`UNICODE_MODE_WINDOWS`**: _(not recommended)_ Windows built-in hex numpad Unicode input. Supports code points up to `0xFFFF`.
-
-  To enable, create a registry key under `HKEY_CURRENT_USER\Control Panel\Input Method` of type `REG_SZ` called `EnableHexNumpad` and set its value to `1`. This can be done from the Command Prompt by running `reg add "HKCU\Control Panel\Input Method" -v EnableHexNumpad -t REG_SZ -d 1` with administrator privileges. Reboot afterwards.
-  This mode is not recommended because of reliability and compatibility issues; use the `UNICODE_MODE_WINCOMPOSE` mode instead.
-
-* **`UNICODE_MODE_BSD`**: _(non implemented)_ Unicode input under BSD. Not implemented at this time. If you're a BSD user and want to help add support for it, please [open an issue on GitHub](https://github.com/qmk/qmk_firmware/issues).
-
-* **`UNICODE_MODE_WINCOMPOSE`**: Windows Unicode input using [WinCompose](https://github.com/samhocevar/wincompose). As of v0.9.0, supports code points up to `0x10FFFF` (all possible code points).
-
-  To enable, install the [latest release](https://github.com/samhocevar/wincompose/releases/latest). Once installed, WinCompose will automatically run on startup. This mode works reliably under all version of Windows supported by the app.
-  By default, this mode uses right Alt (`KC_RALT`) as the Compose key, but this can be changed in the WinCompose settings and by defining [`UNICODE_KEY_WINC`](#input-key-configuration) with a different keycode.
-
-
-## 3. Setting the Input Mode :id=setting-the-input-mode
-
-To set your desired input mode, add the following define to your `config.h`:
+To set the list of enabled input modes, add the `UNICODE_SELECTED_MODES` define to your keymap's `config.h`, for example:
 
 ```c
 #define UNICODE_SELECTED_MODES UNICODE_MODE_LINUX
+// or
+#define UNICODE_SELECTED_MODES UNICODE_MODE_MAC, UNICODE_MODE_WINCOMPOSE
 ```
 
-This example sets the board's default input mode to `UNICODE_MODE_LINUX`. You can replace this with `UNICODE_MODE_MACOS`, `UNICODE_MODE_WINCOMPOSE`, or any of the other modes listed [above](#input-modes). The board will automatically use the selected mode on startup, unless you manually switch to another mode (see [below](#keycodes)).
+These modes can then be cycled through using the `UC_NEXT` and `UC_PREV` keycodes. You can also switch to any input mode, even if it is not specified in `UNICODE_SELECTED_MODES`, using their respective keycodes.
 
-You can also select multiple input modes, which allows you to easily cycle through them using the `UC_NEXT`/`UC_PREV` keycodes.
+If your keyboard has working EEPROM, it will remember the last used input mode and continue using it on the next power up. This can be disabled by defining `UNICODE_CYCLE_PERSIST` to `false`.
 
-```c
-#define UNICODE_SELECTED_MODES UNICODE_MODE_MACOS, UNICODE_MODE_LINUX, UNICODE_MODE_WINCOMPOSE
+<!-- tabs:start -->
+
+### ** macOS **
+
+**Mode Name:** `UNICODE_MODE_MAC`
+
+macOS has built-in support for Unicode input as its own input source. It supports all possible code points by way of surrogate pairs for code points above `U+FFFF`.
+
+To enable, go to **System Preferences → Keyboard → Input Sources**, then add Unicode Hex Input to the list (under Other), and activate it from the input dropdown in the menu bar. Note that this may disable some Option-based shortcuts such as Option+Left and Option+Right.
+
+### ** Linux (IBus) **
+
+**Mode Name:** `UNICODE_MODE_LINUX`
+
+For Linux distros with IBus, Unicode input is enabled by default, supports all possible code points, and works almost anywhere. Without IBus, it works under GTK apps, but rarely anywhere else.
+
+Users who would like support in non-GTK apps without IBus may need to resort to a more indirect method, such as creating a custom keyboard layout.
+
+### ** Windows (WinCompose) **
+
+**Mode Name:** `UNICODE_MODE_WINCOMPOSE`
+
+This mode requires a third-party tool called [WinCompose](https://github.com/samhocevar/wincompose). It supports all possible code points, and is the recommended input mode for Windows.
+
+To enable, install the [latest release from GitHub](https://github.com/samhocevar/wincompose/releases/latest). Once installed, it will automatically run on startup. This works reliably under all versions of Windows supported by WinCompose.
+
+### ** Windows (HexNumpad) **
+
+**Mode Name:** `UNICODE_MODE_WINDOWS`
+
+!> This input mode is *not* the "Alt code" system. Alt codes are not Unicode; they instead follow [the Windows-1252 character set](https://en.wikipedia.org/wiki/Alt_code).
+
+This is Windows' built-in hex numpad Unicode input mode. It only supports code points up to `U+FFFF`, and is not recommended due to reliability and compatibility issues.
+
+To enable, run the following as an administrator, then reboot:
+
+```
+reg add "HKCU\Control Panel\Input Method" -v EnableHexNumpad -t REG_SZ -d 1
 ```
 
-Note that the values are separated by commas. The board will remember the last used input mode and will continue using it on next power-up. You can disable this and force it to always start with the first mode in the list by adding `#define UNICODE_CYCLE_PERSIST false` to your `config.h`.
+### ** Emacs **
 
-#### Keycodes
+**Mode Name:** `UNICODE_MODE_EMACS`
 
-You can switch the input mode at any time by using the following keycodes. Adding these to your keymap allows you to quickly switch to a specific input mode, including modes not listed in `UNICODE_SELECTED_MODES`.

-You can also switch the input mode by calling `set_unicode_input_mode(x)` in your code, where _x_ is one of the above input mode constants (e.g. `UNICODE_MODE_LINUX`).
+**Mode Name:** `UNICODE_MODE_BSD`
 
-?> Using `UNICODE_SELECTED_MODES` is preferable to calling `set_unicode_input_mode()` in `matrix_init_user()` or similar functions, since it's better integrated into the Unicode system and has the added benefit of avoiding unnecessary writes to EEPROM.
+Not currently implemented. If you're a BSD user and want to contribute support for this input mode, please [feel free](contributing.md)!
 
-#### Audio Feedback

+## API :id=api
 
+### `uint8_t get_unicode_input_mode(void)` :id=api-get-unicode-input-mode
 
-## Additional Customization
+Get the current Unicode input mode.
 
-Because Unicode is a large and versatile feature, there are a number of options you can customize to make it work better on your system.
+#### Return Value :id=api-get-unicode-input-mode-return-value
 
-### Start and Finish Input Functions
+The currently active Unicode input mode.
 
-The functions for starting and finishing Unicode input on your platform can be overridden locally. Possible uses include customizing input mode behavior if you don't use the default keys, or adding extra visual/audio feedback to Unicode input.
+---
 
-* `void unicode_input_start(void)` – This sends the initial sequence that tells your platform to enter Unicode input mode. For example, it holds the left Alt key followed by Num+ on Windows, and presses the `UNICODE_KEY_LNX` combination (default: Ctrl+Shift+U) on Linux.
-* `void unicode_input_finish(void)` – This is called to exit Unicode input mode, for example by pressing Space or releasing the Alt key.
+### `void set_unicode_input_mode(uint8_t mode)` :id=api-set-unicode-input-mode
 
-You can find the default implementations of these functions in [`process_unicode_common.c`](https://github.com/qmk/qmk_firmware/blob/master/quantum/process_keycode/process_unicode_common.c).
+Set the Unicode input mode.
 
-### Input Mode Callbacks
+#### Arguments :id=api-set-unicode-input-mode-arguments
 
-There are callbacks functions available that are called whenever the unicode input mode changes. The new input mode is passed to the function.
+ - `uint8_t mode`  
+   The input mode to set.
 
-|Callback                                           |Description                                          |
-|---------------------------------------------------|-----------------------------------------------------|
-| `unicode_input_mode_set_kb(uint8_t input_mode)`   | Callback for unicode input mode set, for keyboard.  |
-| `unicode_input_mode_set_user(uint8_t input_mode)` | Callback for unicode input mode set, for users.     |
+---
 
-This feature can be used, for instance, to implement LED indicators for the current unicode input mode.
+### `void unicode_input_mode_step(void)` : id=api-unicode-input-mode-step
 
-### Input Key Configuration
+Change to the next Unicode input mode.
 
-You can customize the keys used to trigger Unicode input for macOS, Linux and WinCompose by adding corresponding defines to your `config.h`. The default values match the platforms' default settings, so you shouldn't need to change this unless Unicode input isn't working, or you want to use a different key (e.g. in order to free up left or right Alt).

-## Sending Unicode Strings
+---
 
-QMK provides several functions that allow you to send Unicode input to the host programmatically:
+### `void unicode_input_mode_set_user(uint8_t input_mode)` :id=api-unicode-input-mode-set-user
 
-### `send_unicode_string()`
+User-level callback, invoked when the input mode is changed.
 
-This function is much like `send_string()`, but it allows you to input UTF-8 characters directly. It supports all code points, provided the selected input mode also supports it. Make sure your `keymap.c` file is formatted using UTF-8 encoding.
+#### Arguments :id=api-unicode-input-mode-set-user-arguments
 
-```c
-send_unicode_string("(ノಠ痊ಠ)ノ彡┻━┻");
-```
+ - `uint8_t input_mode`  
+   The new input mode.
 
-Example uses include sending Unicode strings when a key is pressed, as described in [Macros](feature_macros.md).
+---
 
-## Additional Language Support
+### `void unicode_input_mode_set_kb(uint8_t input_mode)` :id=api-unicode-input-mode-set-kb
 
-In `quantum/keymap_extras`, you'll see various language files — these work the same way as the ones for alternative layouts such as Colemak or BÉPO. When you include one of these language headers, you gain access to keycodes specific to that language / national layout. Such keycodes are defined by a 2-letter country/language code, followed by an underscore and a 4-letter abbreviation of the character to which the key corresponds. For example, including `keymap_french.h` and using `FR_UGRV` in your keymap will output `ù` when typed on a system with a native French AZERTY layout.
+Keyboard-level callback, invoked when the input mode is changed.
 
-If the primary system layout you use on your machine is different from US ANSI, using these language-specific keycodes can help your QMK keymaps better match what will actually be output on the screen. However, keep in mind that these keycodes are just aliases for the corresponding default US keycodes under the hood, and that the HID protocol used by keyboards is itself inherently based on US ANSI.
+#### Arguments :id=api-unicode-input-mode-set-kb-arguments
 
+ - `uint8_t input_mode`  
+   The new input mode.
 
-## International Characters on Windows
+---
 
-### AutoHotkey
+### `void unicode_input_start(void)` :id=api-unicode-input-start
 
-The method does not require Unicode support in the keyboard itself but instead depends on [AutoHotkey](https://autohotkey.com) running in the background.
+Begin the Unicode input sequence. The exact behavior depends on the currently selected input mode:
 
-First you need to select a modifier combination that is not in use by any of your programs.
-Ctrl+Alt+Win is not used very widely and should therefore be perfect for this.
-There is a macro defined for a mod-tab combo `LCAG_T`.
-Add this mod-tab combo to a key on your keyboard, e.g.: `LCAG_T(KC_TAB)`.
-This makes the key behave like a tab key if pressed and released immediately but changes it to the modifier if used with another key.
+ - **macOS**: Hold `UNICODE_KEY_MAC`
+ - **Linux**: Tap `UNICODE_KEY_LNX`
+ - **WinCompose**: Tap `UNICODE_KEY_WINC`, then U
+ - **HexNumpad**: Hold Left Alt, then tap Numpad +
+ - **Emacs**: Tap Ctrl+X, then 8, then Enter
 
-In the default script of AutoHotkey you can define custom hotkeys.
+This function is weakly defined, and can be overridden in user code.
 
-    <^<!<#a::Send, ä
-    <^<!<#<+a::Send, Ä
+---
 
-The hotkeys above are for the combination CtrlAltGui and CtrlAltGuiShift plus the letter a.
-AutoHotkey inserts the Text right of `Send, ` when this combination is pressed.
+### `void unicode_input_finish(void)` :id=api-unicode-input-finish
 
-### US International
+Complete the Unicode input sequence. The exact behavior depends on the currently selected input mode:
 
-If you enable the US International layout on the system, it will use punctuation to accent the characters. For instance, typing "\`a" will result in à.
-You can find details on how to enable this [here](https://support.microsoft.com/en-us/help/17424/windows-change-keyboard-layout).
+ - **macOS**: Release `UNICODE_KEY_MAC`
+ - **Linux**: Tap Space
+ - **WinCompose**: Tap Enter
+ - **HexNumpad**: Release Left Alt
+ - **Emacs**: Tap Enter
 
-## Software keyboard layout on Linux :id=custom-linux-layout
+This function is weakly defined, and can be overridden in user code.
 
-This method does not require Unicode support on the keyboard itself but instead uses a custom keyboard layout for Xorg. This is how special characters are inserted by regular keyboards. This does not require IBus and works in practically all software. Help on creating a custom layout can be found [here](https://www.linux.com/news/creating-custom-keyboard-layouts-x11-using-xkb/), [here](http://karols.github.io/blog/2013/11/18/creating-custom-keyboard-layouts-for-linux/) and [here](https://wiki.archlinux.org/index.php/X_keyboard_extension). An example of how you could edit the `us` layout to gain 🤣 on `RALT(KC_R)`:
+---
 
-Edit the keyboard layout file `/usr/share/X11/xkb/symbols/us`.
+### `void unicode_input_cancel(void)` :id=api-unicode-input-cancel
 
-Inside `xkb_symbols "basic" {`, add `include "level3(ralt_switch)"`.
+Cancel the Unicode input sequence. The exact behavior depends on the currently selected input mode:
 
-Find the line defining the R key and add an entry to the list, making it look like this:
-```
-key <AD04> {	[	  r,	R, U1F923		]	};
-```
+ - **macOS**: Release `UNICODE_KEY_MAC`
+ - **Linux**: Tap Escape
+ - **WinCompose**: Tap Escape
+ - **HexNumpad**: Release Left Alt
+ - **Emacs**: Tap Ctrl+G
 
-Save the file and run the command `setxkbmap us` to reload the layout.
+This function is weakly defined, and can be overridden in user code.
 
-You can define one custom character for key defined in the layout, and another if you populate the fourth layer. Additional layers up to 8th are also possible.
+---
 
-This method is specific to the computer on which you set the custom layout. The custom keys will be available only when Xorg is running. To avoid accidents, you should always reload the layout using `setxkbmap`, otherwise an invalid layout could prevent you from logging into your system, locking you out.

 ```
 
+If the programs you use bind an action to taps of modifier keys (e.g. tapping left GUI to bring up the applications menu or tapping left Alt to focus the menu bar), you may find that using retro-tapping falsely triggers those actions. To counteract this, you can define a `DUMMY_MOD_NEUTRALIZER_KEYCODE` in `config.h` that will get sent in between the register and unregister events of a held mod-tap key. That way, the programs on your computer will no longer interpret the mod suppression induced by retro-tapping as a lone tap of a modifier key and will thus not falsely trigger the undesired action.
+
+Naturally, for this technique to be effective, you must choose a `DUMMY_MOD_NEUTRALIZER_KEYCODE` for which no keyboard shortcuts are bound to. Recommended values are: `KC_RIGHT_CTRL` or `KC_F18`. 
+Please note that `DUMMY_MOD_NEUTRALIZER_KEYCODE` must be a basic, unmodified, HID keycode so values like `KC_NO`, `KC_TRANSPARENT` or `KC_PIPE` aka `S(KC_BACKSLASH)` are not permitted.
+
+By default, only left Alt and left GUI are neutralized. If you want to change the list of applicable modifier masks, use the following in your `config.h`:
+
+```c
+#define MODS_TO_NEUTRALIZE { <mod_mask_1>, <mod_mask_2>, ... }
+```
+
+Examples:
+
+```c
+#define DUMMY_MOD_NEUTRALIZER_KEYCODE KC_RIGHT_CTRL
+
+// Neutralize left alt and left GUI (Default value)
+#define MODS_TO_NEUTRALIZE { MOD_BIT(KC_LEFT_ALT), MOD_BIT(KC_LEFT_GUI) }
+
+// Neutralize left alt, left GUI, right GUI and left Control+Shift
+#define MODS_TO_NEUTRALIZE { MOD_BIT(KC_LEFT_ALT), MOD_BIT(KC_LEFT_GUI), MOD_BIT(KC_RIGHT_GUI), MOD_BIT(KC_LEFT_CTRL)|MOD_BIT(KC_LEFT_SHIFT) }
+```
+
+!> Do not use `MOD_xxx` constants like `MOD_LSFT` or `MOD_RALT`, since they're 5-bit packed bit-arrays while `MODS_TO_NEUTRALIZE` expects a list of 8-bit packed bit-arrays. Use `MOD_BIT(<kc>)` or `MOD_MASK_xxx` instead.

 ### Retro Shift
 
 [Auto Shift,](feature_auto_shift.md) has its own version of `retro tapping` called `retro shift`. It is extremely similar to `retro tapping`, but holding the key past `AUTO_SHIFT_TIMEOUT` results in the value it sends being shifted. Other configurations also affect it differently; see [here](feature_auto_shift.md#retro-shift) for more information.
