# Releases
|
|
|
|
History of Klipper releases. Please see
|
|
[installation](Installation.md) for information on installing Klipper.
|
|
|
|
## 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/Klipper3d/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
|
|

|
|
|
|
## Klipper 0.9.0
|
|
|
|
Available on 20201020. Major changes in this release:
|
|
* Support for "Input Shaping" - a mechanism to counteract printer
|
|
resonance. It can reduce or eliminate "ringing" in prints.
|
|
* New "Smooth Pressure Advance" system. This implements "Pressure
|
|
Advance" without introducing instantaneous velocity changes. It is
|
|
also now possible to tune pressure advance using a "Tuning Tower"
|
|
method.
|
|
* New "webhooks" API server. This provides a programmable JSON
|
|
interface to Klipper.

|
|
identification code and micro-controllers can now report their
|
|
unique serial numbers during USB identification.
|
|
* New kinematic support for "Rotary Delta" and "CoreXZ" printers.
|
|
* Micro-controller improvements: support for stm32f070, support for
|
|
stm32f207, support for GPIO pins on "Linux MCU", stm32 "HID
|
