Acorn 8 how to export the new image formats

I downloaded Acorn 8.

At the moment it looks like the previous Acorn (although the size of the program is bigger).
How can I export an image as JPEG-XL. I can not see this option.

Found it, it is at Export (web & others). I did not expect to find it here.

I’m glad you found it.

The export window has the ability to have more options for the various formats, and most importantly, a preview of what you’re getting.

The Save As… menu still has various options because of legacy reasons. Maybe I should put a note in there about the main export window, just in case somebody doesn’t know about it.
