-WIP
+### Changed
+
+- Renamed `credentials.json` to `creds.yml` (example in `creds_example.yml`)
+  - Most of the credentials from 2.x will be automatically migrated
+- Code cleanup
+  - Command attributes cleaned up
+    - Removed dummy Remarks and Usages attributes as hey were unused for a few patches but stayed in the code to avoid big git diffs
+  - All database migrations and data (json file) migrations have been removed
+    - As updating to the latest 2.x version before switching over to v3 is mandated (or fresh v3 install), that means all migration code has ran and it can be safely removed 
+  - There are 2 projects: NadekoBot and NadekoBot.Coordinator
+    - You can directly run NadekoBot as the regular bot with one shard
+    - Run NadekoBot.Coordinator if you want more control over your shards and a grpc api for coordinator with which you can start, restart, kill and see status of shards
+  - todo: Reworked from source installation (linux/windows) guide <todo link>
+  - todo: Added docker support, installation guide at <todo link>
+- Guides
+  - Now instruct users to set build output to nadekobot/output instead of running from nadekobot/src/NadekoBot
+
+### Fixed
+
+- Fixed many response strings which were formatted or used incorrectly
