 ## [Unreleased]
 
+## [2.0.0-beta.6] - 2022-10-21
+
 ### Added
 - Added feature to install custom firmware from file ([pybricks-code#1020]).
+- Added support for multi-file programs ([support#189]).
+
+### Changed
+- Updated dependencies.
+- Updated documentation.
+- Updated APIs for code completions.
+- Update hub firmware to v3.2.0b4:
+
+  ### Added
+  - Added hub shutdown status light indication.
+  - Added boot and shutdown light matrix animations.
+  - Added new indication for over-charging battery (blinking green light).
+  - Added iterator protocol support to `geometry.Matrix` class.
+  - Added support for multi-file projects ([pybricks-micropython#115]).
+  - Added new `System.storage()` API ([support#85]).
+
+  ### Changed
+  - Battery full indication (green light) comes on earlier ([support#647]).
+  - User program is saved to non-volatile memory at shutdown on all hubs.
+  - Restored the `Motor.speed()` method and `DriveBase` equivalent to provide
+    speed as a numerical derivative of the motor position.
+  - Starting REPL automatically imports all modules ([support#741]).
+  - Updated Bluetooth to [Pybricks Profile v1.2.0][pp1.2.0].
+  - Bluetooth now uses random private address instead of static public address
+    ([support#600]).
+
+  ### Fixed
+  - Fixed motors going out of sync when starting program ([support#679]).
+  - Fixed motor torque signal overflowing under load ([support#729]).
+  - Fixed city hub turning back on after shutdown ([support#692]).
+  - Fixed IMU I2C bus lockup on SPIKE hubs ([support#232]).
+  - Fixed REPL history corrupt after soft reset ([support#699]).
+  - Fixed "ValueError: incompatible .mpy file" when pressing the button when
+    there is no program yet ([support#599]).
