   - **IMPORTANT INFO WHEN UPGRADING TO GRBL v0.9g:** 
   - Baudrate is now **115200** (Up from 9600). 
   - Settings WILL be overwritten. Please make sure you have a backup. Also, settings have been renumbered and some have changed how they work. See our [Configuring v0.9 Wiki page](https://github.com/grbl/grbl/wiki/Configuring-Grbl-v0.9) for details.
