Controller 2.4.7 has been released. Debian packages are availble from the regular package servers. A source tarball is available at [http://linuxcnc.org/emc2/dists/lucid/emc2.4/source/emc2_2.4.7.tar.gz] Due to a mistake during packaging, this version will still identify itself as version 2.4.6 in the splash screen and about dialog. To verify the version of that you have installed, open a terminal window and type: dpkg -l emc2 OR dpkg -l emc2-sim depending on whether you have installed the realtime or simulator-only version of the software. The output should say something like this: ii emc2 1:2.4.7 PC based motion controller for real-time Lin Because of a problem with the virtual machine used to build the 64-bit hardy (ubuntu 8.04) packages, version 2.4.7 is unavailable for that system at this time. All packages for lucid are available, as are packages for 32-bit hardy. The following changes and bugfixes have been made since the last release: * axis: fix problem removing a single notification * axis: fix jog after ctrl-alt-left or -right in mdi * classicladder: fix a problem when more than 8 modbus inputs are read * classicladder: fix possible crashes * comp: fix a problem with 'option userinit yes" * emcrsh: minor bugfixes * halcmd: fix a possible crash * halrmt: fix a possible crash * halmeter: fix a possible crash * hal_input: add names for new input events * hal_motenc: set outputs to 0 on exit * interpreter: fix spurious cutter comp error with tiny arcs in metric * interpreter: fix G10 L2 on the active coordinate system * interpreter: disallow changing coordinate system with cutter comp on * interpreter: fix incorrect handling of do-break-while (SF#3420655) * motion: fix spurious reversal in CSS mode with M4 and X=0 * motion: fix a problem with probing (SF#3040806) * pncconf: fix nameless 'addf' in HAL file * pncconf: changes spaces in configuration names to underscores * pncconf: fixes for 3i28 and 7i43-4 boards * pncconf: fix scale calculation * pncconf: fix scaled spindle speed display * stepconf: changes spaces in configuration names to underscores * stepconf: fix for spindle PWM on pin 17 * stepconf: fix name of "Z Both Limit + Home" pin * stepconf: fix scaled spindle speed display * stepconf: advice about how to use on an 800x600 display * thc: correctly remove offset after compensation disabled * documentation: various improvements * configs/smithy: various updates * configs/gantry: simulated XYYZ gantry configuration Thanks to the dozen or so developers who have contributed fixes and improvements to this version.
