As Geert mentioned earlier: Notes should be exported in all formats
Enterprise Architect supports some formats that don't support notes. Obviously 'all' is incorrect.
I have't tested it in build 1626 but it should be the case.
I don't think it has changed in 1627 or 1628, but just FYI 1626 hasn't been the latest version since July.
If the issue is that notes aren't updated over existing elements (that is a know issue and has been reported)
It's better to report this again (I asked it during global summit and its probably not high enough on the bugs to be fixed list)
No. What's being reported is that attribute notes are only available in the EA extensions for a particular XMI version, which means that if you turn that off they aren't included at all. I don't know what you asked in the global summit, but if you want it looked at I'd suggest you
Report a Bug. I don't think questions asked during the summit are passed on as issues to investigate.
Its also not specifically mentioned on the slide on things that will be improved (so perhaps it is working as intended for some yet unknown reason to the community?)
Have you ever seen our release notes for a major version? If it covered things at this level you would need every line in the release notes on that slide. You wouldn't fit it in 10 slides.
