Upcoming v0.13.0 release

Developers

I’m planning to make the next release of Klipper - I’ll look to tag this release as “v0.13.0”.

I am going to target a release date of 20250410 - a little over one week out.

There are several upcoming changes in the works - loadcell support, stm32h7 speed increases, generic cartesian support, 6-axis support, and others. These changes will provide a nice benefit for users, but they also have the potential for introducing regressions. So, I think it would be worthwhile to tag a release before making significant changes.

I’ll follow up on this topic with draft release notes.

Let me know if there are any comments or concerns. If you know of any important bug fixes that should be made prior to the release then please open a PR in as soon as possible.

Draft release notes:

Klipper 0.13.0

Available on 202504??. Major changes in this release:

  • New “sweeping vibrations” resonance testing mechanism for input shaper.
  • Fans and GPIO pins can now be assigned a formula (via Jinja2 “templates”).
  • The bed_mesh code now supports “adaptive bed mesh”. The area probed can be adjusted for the size of the print.
  • A new minimum_cruise_ratio kinematic parameter has been added (it replaces the previous max_accel_to_decel parameter).
  • Several new sensors added:
    • Support for ldc1612 “eddy” current sensors. This includes probing support, fast “scan” probing, and temperature calibration.
    • New support for “load cell” measurements. Support for connecting these load cells to hx71x and ads1220 ADC sensors.
    • Support for BMP180, BMP388, and SHT3x temperature sensors. Support for ADS1x1x ADC chips commonly used for temperature measurements.
    • New lis3dh and icm20948 accelerometer support.
    • Support for mt6816 and mt6826s “hall angle” sensors.
  • New micro-controller improvements:
    • New support for rp2350 micro-controllers.
    • The existing rp2040 chip has been extended to run at 200MHz.
    • The micro-controller code can now define many more commands (up to 16384 from 128).
  • New modules added: pwm_tool, pwm_cycle_time, garbage_collection, error_mcu, aip31068_spi, canbus_stats.
  • Several bug fixes and code cleanups.

I’m thinking of pushing the release back one day and tagging the release on 20250411.

Cheers,
-Kevin
