After quite a bit of hemming and hawing, I have decided to release Doors CS 5.8 Beta 1,the final new major beta before release candidacy for Doors CS 6 begins. This version contains a plethora of bug fixes and upgrades, such as solutions to the icon misalignment with folders and several GUI issues that elfprince13, our now-retired administrator, helped me to find. The shell expansions system has been completely rewritten and optimized for speed; information on SEs can be found in the wiki. New features have been added as well, from the bright and shiny new Intelligent Writeback (IW) execution subsystem to the spiffy second-generation associated program subsystem. As with all previous beta releases, please download it, try it out, post any comments, suggestions, praise, rants, and bug reports on the forum, and especially let me know if you'd like to learn more about developing for DCS6.
