Version	Release Date	Description
Ver 0.53.263 (Download)	5 Feb 2019	Major changes for this release, see the release notes for a complete list of changes - ( (Click here for release notes): (1) Fixed bugs in probing code that sometimes caused a jump in machine position after the probe motion had completed. This bug also caused a mis-match between the actual machine position and Mach4's internal calculated machine position. (2) Fixed bug when re-synchronizing position after a probe touch. (3) Fixed bug that causes the Mach4 GUI window to suddenly close after approximately 6 minutes or GCode running time. (4) Fixed a bug that under rare circumstances would cause Mach4 to crash. (5) Fixed bug when configuring the PMDX-424 step and direction signals for use with two each PMDX-133 boards on the ribbon header.
Ver 0.52.254 (Download)	18 Aug 2017	Major changes for this release (see the release notes for a complete list of changes): (1) Revised startup code to avoid memory corruption that happened if plugin used the Mach4 API before Mach4 was ready.

Ver 0.48.235 (Download) 7,410 KBytes	22 Dec 2016	Major changes for this release (see the release notes for a complete list of changes): (1) Encoder/tach support for "synthetic" index so you can use an encoder or tach for measuring spindle RPM and threading without needing a physical index pulse. See the release notes for more information. (2) Threading support using either 1 pulse-per-revolution index pulse, a bi-directional quadrature encoder or uni-directional single-line tach input. See the release notes for more information. (3) Fixes and enahancements to PMDX-424 and PMDX-179 combination regarding the "Probe" and "Error Code" LED behavior (see release notes for details). (4) BUG FIX: Add workaround for Mach4 motion planner anomaly that that occasionally caused GCode files to hang. (5) BUG FIX: Fix bug in encoder interface that caused spurious values when then encoder was rotating in the reverse direction. (6) BUG FIX: Fix a bug in the real-time display that could show a PWM output as not active (i.e. not toggling) when it actually is toggling. (7) BUG FIX: Fix a bug that incorrectly changed the spindle pulse frequency based on the PWM minimum duty cycle. (8) Homing code now ignores variable from the Mach4 core that caused our plug-in to sometimes not allow an axis to be homed. Click here to view the release notes for this version. This version will run on Mach4 build 2872 through 3233, and has been tested with Mach4 builds 2914 and 3233 on Win XP, Win 7, and Win 8 in our test environments.
