+# QMK Breaking Change - 2019 Aug 30
+
+Four times a year QMK runs a process for merging Breaking Changes. A Breaking Change is any change which modifies how QMK behaves in a way that is incompatible or potentially dangerous. We limit these changes to 4 times per year so that users can have confidence that updating their QMK tree will not break their keymaps.
+
+This document marks the inaugural Breaking Change merge. A list of changes follows.
+
+## LUFA USB descriptor cleanup
+
+* Some code cleanups related to the USB HID descriptors on AVR keyboards, to make them easier to read and understand
+* More information: see https://github.com/qmk/qmk_firmware/pull/4871
+* No behaviour changes anticipated and no keymaps modified
+
+## Migrating `ACTION_LAYER_MOMENTARY()` entries in `fn_actions` to `MO()` keycodes
+
+* `fn_actions` is deprecated, and its functionality has been superseded by direct keycodes and `process_record_user()`
+* The end result of removing this obsolete feature should result in a decent reduction in firmware size and code complexity
+* All keymaps affected are recommended to switch away from `fn_actions` in favour of the [custom keycode](https://docs.qmk.fm/#/custom_quantum_functions) and [macro](https://docs.qmk.fm/#/feature_macros) features
+
+## Update Atreus to current code conventions
+
+* Duplicate include guards have bypassed the expected header processing behavior
+* All keymaps affected are recommended to remove duplication of `<keyboard>/config.h` to `<keyboard>/keymaps/<user>/config.h` and only provide overrides at the keymap level
+
+## Backport changes to keymap language files from ZSA fork
+
+* Fixes an issue in the `keymap_br_abnt2.h` file that includes the wrong source (`keymap_common.h` instead of `keymap.h`)
+* Updates the `keymap_swedish.h` file to be specific to swedish, and not just "nordic" in general. 
+* Any keymaps using this will need to remove `NO_*` and replace it with `SE_*`. 
+
+## Update repo to use LUFA as a git submodule
+
+* `/lib/LUFA` removed from the repo
+* LUFA set as a submodule, pointing to qmk/lufa
+* This should allow more flexibility with LUFA, and allow us to keep the sub-module up to date, a lot more easily.  It was ~2 years out of date with no easy path to fix that.  This prevents that from being an issue in the future
+  
+## Migrating `ACTION_BACKLIGHT_*()` entries in `fn_actions` to `BL_` keycodes
+
+* `fn_actions` is deprecated, and its functionality has been superseded by direct keycodes and `process_record_user()`
+* All keymaps using these actions have had the relevant `KC_FN*` keys replaced with the equivalent `BL_*` keys
+* If you currently use `KC_FN*` you will need to replace `fn_actions` with the [custom keycode](https://docs.qmk.fm/#/custom_quantum_functions) and [macro](https://docs.qmk.fm/#/feature_macros) features
+
+## Remove `KC_DELT` alias in favor of `KC_DEL`
+
+* `KC_DELT` was a redundant, undocumented alias for `KC_DELETE`
+* It has been removed and all its uses replaced with the more common `KC_DEL` alias
+* Around 90 keymaps (mostly for ErgoDox boards) have been modified as a result

+# Breaking Changes
+
+This document describes QMK's Breaking Change process. A Breaking Change is any change which modifies how QMK behaves in a way that in incompatible or potentially dangerous. We limit these changes so that users can have confidence that updating their QMK tree will not break their keymaps.
+
+The breaking change period is when we will merge PR's that change QMK in dangerous or unexpected ways. There is a built-in period of testing so we are confident that any problems caused are rare or unable to be predicted.
+
+## What has been included in past Breaking Changes?
+
+* [2019 Aug 30](ChangeLog/20190830.md)
+
+## When is the next Breaking Change?
+
+The next Breaking Change is scheduled for Nov 29.
+
+### Important Dates
+
+* [ ] 2019 Oct 04 - `future` is created. It will be rebased weekly.
+* [ ] 2019 Nov 01 - `future` closed to new PR's.
+* [ ] 2019 Nov 01 - Call for testers.
+* [ ] 2019 Nov 27 - `master` is locked, no PR's merged.
+* [ ] 2019 Nov 29 - Merge `future` to `master`.
+* [ ] 2019 Nov 30 - `master` is unlocked. PR's can be merged again.
+
+## What changes will be included?
+
+To see a list of breaking change candidates you can look at the [`breaking_change` label](https://github.com/qmk/qmk_firmware/pulls?q=is%3Aopen+label%3Abreaking_change+is%3Apr). New changes might be added between now and when `future` is closed, and a PR with that label applied is not guaranteed to be merged.
+
+If you want your breaking change to be included in this round you need to create a PR with the `breaking_change` label and have it accepted before `future` closes. After `future` closes no new breaking changes will be accepted.
+
+Criteria for acceptance:
+
+* PR is complete and ready to merge
+* PR has a ChangeLog
+
+# Checklists
+
+This section documents various processes we use when running the Breaking Changes process.
+
+## Rebase `future` from `master`
+
+This is run every Friday while `future` is open.
+
+Process:
+
+```
+cd qmk_firmware
+git checkout master
+git pull --ff-only
+git checkout future
+git rebase master
+git push --force
+```
+
+## 8 Weeks Before Merge

+        * [ ] Add a big notice at the top that this is a testing branch.
+        * [ ] Include a link to this document
+    * [ ] `git commit -m 'Branch point for <DATE> Breaking Change'`
+    * [ ] `git tag breakpoint_<YYYY>_<MM>_<DD>`
+    * [ ] `git tag <next_version>` # Prevent the breakpoint tag from confusing version incrementing
+    * [ ] `git push origin future`
+    * [ ] `git push --tags`

+    * [ ] Any that have a ChangeLog entry may be merged immediately.

+## 2 Days Before Merge
+
+* Announce that master is closed for 2 days
+    * [ ] Discord
+    * [ ] GitHub PR
+    * [ ] https://reddit.com/r/olkb
+
+## Day Of Merge
+
+* `qmk_firmware` git commands
+    * [ ] `git checkout future`
+    * [ ] `git pull --ff-only`
+    * [ ] `git rebase origin/master`
+    * [ ] Edit `readme.md`
+        * [ ] Remove the notes about `future`
+    * [ ] Roll up the ChangeLog into one file.
+    * [ ] `git commit -m 'Merge point for <DATE> Breaking Change'`
+    * [ ] `git push origin future`
+* Github Actions
+    * [ ] Create a PR for `future`
+    * [ ] Make sure travis comes back clean
+    * [ ] Merge `future` PR

-# NOTICE: THIS IS A TESTING BRANCH
-
-This is the `breaking_changes` branch for Aug 2019. You can [read more in the tracking issue](https://github.com/qmk/qmk_firmware/issues/6146).
-
-We encourage you to try this branch out and see if there are any bugs. Our goal is to merge this branch to `master` on Aug 30. Please [report any bugs](https://github.com/qmk/qmk_firmware/issues/new?template=bug_report.md) you find.
-
-Original readme.md continues:
-
 This is a keyboard firmware based on the [tmk\_keyboard firmware](https://github.com/tmk/tmk_keyboard) with some useful features for Atmel AVR and ARM controllers, and more specifically, the [OLKB product line](https://olkb.com), the [ErgoDox EZ](https://ergodox-ez.com) keyboard, and the [Clueboard product line](https://clueboard.co).
