Thank you Peter for telling this. I indeed see it when I check for updates from the RoboHelp menu. The what's new text shows the link https://helpx.adobe.com/robohelp/kb/fixed-issues.html to see details, but these are not yet available. I guess that we just have to wait a while for the details to be published.
That thread should have been locked as it is an Announcement only. I have moved your question to a new thread.
I see this when I click your link.
Focus in the menu is further down on Fixed Issues. The only feature is Windows 11 certification. The rest is bug fixes.
My site www.grainge.org includes many free Authoring and RoboHelp resources that may be of help.
Strange. This is my screen when I click the link and after clearing the cache of my web browser.
It now shows the same as your screenshot. I guess that it took a while for the update of that page to be available here.
