OmniOutliner 3.9.3 is now available! All HTML exporters and Paste with Current Style should now be working correctly. And for the first time in… years? The help file has been updated to reflect the changes in past versions! Currently only the English version has been updated, but we will do another release as soon as the localized versions are ready.
There's also a couple of other bug fixes in this release. Please see the release notes for full details and when you're ready, download it manually or use the built-in software updater. As always, please contact us using Help -> Send Feedback or at email@example.com if you run into any problems or have a question. Thanks!
