Copied from the LSP site. http://www.lightshowpro.com/lightshow-change-log/3400-new-release-4724-5112-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/improvments made. 1. Modified Twinkle and Shimmer routine for E1.31 output 2. Modified Pixelnet and DMX Pro output plugins for improved playback 3. Modified D-Light/LOR plugin to fix playback issues where output was not staying active 4. Added Optimize Sequence button to Sequencer Main Tool Bar. You can right click on it and add it to the quick access toolbar if you want it available all the time.
