from http://www.lightshowpro.com/lightshow-change-log/3466-new-release-4738_19737-a.html The management of LSPro, in coordination with the QCC, the Beta-testing Team and the LSPro programming team, are pleased to offer this new fix-release to V2.5. This is a minor change to the software. We strongly advise making sure you have all of your files backed up to include the install files for the last public release numbered 2.5.4720.315 or earlier to insure you can return to your current state in the event of any undiscovered issues with this release. Below please find a list of the fixes/improvements made. Adds ability to zone E1.31 controllers to improve output performance With this you can split your e1.31 into zones to achieve better performance Performance improvements to Pixelnet and DMX Pro plugins Adds pop-up dialog if sequence has been scheduled before to re-use existing optimized commands Since the Optimized format has changed you should be forced to re-optimize the first time thru. Fixed Minleon export Changed scheduler optimized command file format. You will need to rebuild your show(s) as a result of this. Other scheduler stability and performance improvements Added a command buffer size in the scheduler setting. You can adjust this size to achieve better performance The command buffer size was mainly for testing purposes, but it left it in there to allow users to be able tweak and use. The default value is 100000 which is what was hard coded before. This number basically represents the maximum amount of commands at a time that will be buffered from the disk for playback. Smaller shows will probably never even hit this number, so this is mainly for the larger shows. However, if you raise this number it could cause negative issues as now you start to use more memory. You can change it during your show and it will take effect at the beginning of playback for each sequence in your show.
