OmniOutliner 3.6.4 beta 1 is now available and is as usual free for all 3.x owners. Sorry, no QuickLook support yet but that is coming later. This fixes the 10.5 crash we missed in the last release and the Spaces bug that switched you to OmniOutliner on an autosave. And, exciting news for some, the “a” prefix bug is hopefully fixed with this release as well!
If you encounter any problems with this release, please let us know!
