+## Klipper 0.10.0
+
+Available on 20210929. Major changes in this release:
+* Support for "Multi-MCU Homing". It is now possible for a stepper
+ motor and its endstop to be wired to separate micro-controllers.
+ This simplifies wiring of Z probes on "toolhead boards".
+* Klipper now has a
+ [Community Discord Server](https://discord.klipper3d.org)
+ and a [Community Discourse Server](https://community.klipper3d.org).
+* The [Klipper website](https://www.klipper3d.org) now uses the
+ "mkdocs" infrastructure. There is also a
+ [Klipper Translations](https://github.com/KevinOConnor/klipper-translations)
+ project.
+* Automated support for flashing firmware via sdcard on many boards.
+* New kinematic support for "Hybrid CoreXY" and "Hybrid CoreXZ"
+ printers.
+* Klipper now uses `rotation_distance` to configure stepper motor
+ travel distances.
+* The main Klipper host code can now directly communicate with
+ micro-controllers using CAN bus.
+* New "motion analysis" system. Klipper's internal motion updates and
+ sensor results can be tracked and logged for analysis.
+* Trinamic stepper motor drivers are now continuously monitored for
+ error conditions.
+* Support for the rp2040 micro-controller (Raspberry Pi Pico boards).
+* The "make menuconfig" system now utilizes kconfiglib.
+* Many additional modules added: ds18b20, duplicate_pin_override,
+ filament_motion_sensor, palette2, motion_report, pca9533,
+ pulse_counter, save_variables, sdcard_loop, temperature_host,
+ temperature_mcu
+* Several bug fixes and code cleanups.
