Marlin 1.1.0-RC8 Release
🕑 Added 2016-12-06 08:06:16 +0000 UTC After over 130 days of poring over submissions, cleaning up code, and playing hide-and-seek with sneaky bugs, I'm thrilled, pleased, and bloody well relieved to announce the official release of Marlin 1.1.0-RC8!This release candidate represents the work of dozens of volunteers and contributors who produced over 900 individual commits to improve and refine Marlin. We hope you find these changes improve your 3D printing experience!
The biggest changes since 1.1.0-RC7 are…
- Major performance improvement for Graphical LCDs
- Simplified probe configuration
- Enable Auto Bed Leveling by type
- Reduce serial communication errors
- Make Bilinear (Mesh) Grid Leveling available for non-delta
- Support for Trinamic TMC2130 SilentStepStick SPI-based drivers
- Add `M211` to Enable/Disable Software Endstops
- Add `M355` to turn the case light on/off and set brightness

Beta Notes
Marlin 1.1.0-RC8 is beta software and may have bugs. So proceed with caution and please report any issues you experience. While we have tried our best to test each change, we cannot guarantee it will work perfectly with your particular machine and peripherals.
In Other News…
Marlin Firmware now has a Twitter! Follow @MarlinFirmware for the latest news, tips & tricks, and release announcements about Marlin and related stuff.
We're working on 32-bit support in the main Marlin project, beginning with a Hardware Access Layer (HAL) for Due/Duo boards while maintaining full support for 8-bit AVR. Please contribute to help move this project forward.
As always, thank you for your support!
