I did not notice the change , though there was a mention in the release notes - sometimes I try and guess what the change was from the short description. It also was about the same time when the Save As was added to the drop down File menu , so I think I assumed that it was referring to that.
I know that someone on another forum wanted the ability to be able to do a Save As of the FSEQ directly to the relevant PI/BBB FP folders (rather than two steps) - they must be the more advanced users.
I need to document this in the manual. I will try it out after the next release , but am guessing that with Save As , I can direct both the xml and fseq somewhere else , then if I click on Save it will save in my current Show directory - then I will wonder why something is not working
