##Update Summary for v1.0
##Update Summary for v1.1
- **IMPORTANT:** Your EEPROM will be wiped and restored with new settings. This is due to the addition of two new spindle speed '$' settings.
- New safety door parking motion as a compile-option. Grbl will retract, disable the spindle/coolant, and park near Z max. When resumed, it will perform these task in reverse order and continue the program. Highly configurable. See config.h for details.
- **Real-time Overrides** : Alters the machine running state immediately with feed, rapid, spindle speed, spindle stop, and coolant toggle controls. This huge contribution by the Grbl project is feature that is common only on industrial machines, often used to optimize cutting while the job is running. Most hobby CNC's try to mimic this with varying results.
- **Jogging Mode** : New jogging commands seperate from the g-code parser, so that the parser state doesn't get altered and cause a potential crash if not restored properly. Documentation is included on how to use this with a joystick with a low-latency.
- **Laser Mode** : Grbl now has a "laser" mode, where consecutive G1, G2, and G3 commands do not stop and continuously move through them with a spindle speed change. Spindle speed overrides also work with laser mode so you can tweak the laser power, if you need to during the job. Switch between "laser" mode and "normal" mode via a `$` setting.
- **Significant Interface Improvements**: Just this one time and done simultaneously with adding override controls, Grbl has tweaked the communication interface to make it easier for developers to write better GUIs. _NOTE: GUIs need to specifically update their code to be compatible with v1.1 and later._
- **New Status Reports**: To account for the additional override data, status reports have been tweaked to cram more data into it, while still being smaller than before. Documentation is included, outlining how it has been changed.
- **Improved Error/Alarm Feedback** : All Grbl error and alarm messages have been changed to providing a code. Each code is associated with a specific problem, so users will know exactly what is wrong without having to guess. Documentation and an easy to parse CSV is included in the repo.
- **Extended-ASCII realtime commands** : All overrides and future real-time commands are defined in the extended-ASCII character space. Unfortunately not easily type-able on a keyboard, but helps prevent accidental commands from a g-code file having these characters and gives lots of space for future expansion.
- **Message Prefixes** : Every message type from Grbl has a unique prefix to help GUIs immediately determine what the message is and parse it accordingly without having to know context. The prior interface had several instances of GUIs having to figure out the meaning of a message, which made everything more complicated than it needed to be.
- New OEM specific features, such as safety door parking, single configuration file build option, EEPROM restrictions and restoring controls, and storing product data information.
- New safety door parking motion as a compile-option. Grbl will retract, disable the spindle/coolant, and park near Z max. When resumed, it will perform these task in reverse order and continue the program. Highly configurable, even to add more than one parking motion. See config.h for details.
- New '$' Grbl settings for max and min spindle rpm. Allows for tweaking the PWM output to more closely match true spindle rpm. When max rpm is set to zero or less than min rpm, the PWM pin D11 will act like a simple enable on/off output.
- Updated G28 and G30 behavior from NIST to LinuxCNC g-code description. In short, if a intermediate motion is specified, only the axes specified will move to the stored coordinates, not all axes as before.
- Lots of minor bug fixes and refactoring to make the code more efficient and flexible.
- **NOTE:** Arduino Mega2560 support has been moved to an active, official Grbl-Mega [project](http://www.github.com/gnea/grbl-Mega/). All new developments here and there will be synced when it makes sense to.
- Single file configuration for custom firmware.
- A few bug fixes and lots of refactoring to make the code more efficient and flexible.
