LinuxCNC 2.7.3 released

LinuxCNC 2.7.3 is out! This one has a couple of important bug fixes, one related to run-from-line and g-code remapping, and one related to halui jogging. All 2.7 users are encouraged to upgrade.

This release was brought to us by several developers, including two first-time committers to LinuxCNC. A special welcome to Salvatore Balestrino (who fixed a sort-order bug in the tooledit gui) and Bernhard Wiedemann (who fixed a compile error with boost 1.58). As always, thanks to everyone who contributed:

• Salvatore Balestrino
• Bernhard M. Wiedemann
• Dewey Garrett
• Jeff Epler
• John Morris
• John Thornton
• Norbert Schechner
• Robert W. Ellenberg
• Sebastian Kuzminsky
