 Some of the major new features of this version are:
   - the new HAL configuration file that introduces a more flexible way to modify the HAL and give customization power of LinuxCNC.
   - the addition off new PID and encoder modules to be used by the new HAL config, powered by an internal RTC clock.
-  - integration [tinyUSB](https://github.com/hathach/tinyusb), a complete USB stackframe that simplifies the creation of HAL code for new MCU.
+  - integration [tinyUSB](https://github.com/hathach/tinyusb), a complete USB stack frame that simplifies the creation of HAL code for new MCU.
   - the addition of an option for a 16-bit version of the bresenham line algorithm that can improve step rate for weak 8-bit processors or for specific applications like laser engraving.
   - several revisions, improvements and important bug fixes in the core of µCNC to generate reliable stepping code.
 
 ### Added
-  - added basic settings for grbl if startup emulation enabled (this includes $1-it's not used and always returns 0 and $11-that sets the G64-cosine factor. This value should be between -1 and 1. If 0 it acts as G61-exact path mode and -1 acts as G61.1 exact stop mode) (#55)

   - $0-max step rate is now used to top limit stepping frequency (#55)

 ## [1.1.2] - 2021-06-23
 
 Version 1.1.2 fixes a critical error on the STM32 HAL that cause several IO problems. µCNC core and AVR have no changes from the previous version:
