- Increment to v1.1b due to status report tweak. - Tweaked the buffer state status reports to show bytes and blocks available, rather than in use. This does not require knowing the buffer sizes beforehand. It’s implicit. - Also, since buffer states are not used by most devs (after inquiries), it is no longer enabled by default and a status mask option was added for this. - Fixed some typos and updated for the report tweak in the documentation. - Wrote a joystick implementation concept in the jogging markdown document. Outlines how to get a low-latency feel to a joystick (and other input devices). - Removed XON/XOFF support. It’s not used by anyone because of its inherent problems. Remains in older versions for reference. - Added a compile option on how to handle the probe position during a check mode. - Fixed a jogging bug. If G93 is the modal state before a jogging motion, the feed rate did not get calculated correctly. Fixed the issue. - Refactored some code to save another 160+ bytes. Included an improved float vector comparison macro and reducing a few large and repetitive function calls. - Fixed a probing bug (existing in v0.9 too) where the target positions were not set correct and error handling was improper.
