do you mean users as humans or as apps? There may have been some
changes in the command line options and weston.ini, but I think they
have generally been fairly stable. The biggest impact on app support
was probably the xdg-shell v5 era and the eventual removal of it.
I can't really remember even 5.0 release, but I would hope the notable
changes would have been mentioned in the release announcements.
Oh, removal of the Raspberry Pi backend, and removal of EGL support
from the fbdev-backend come to mind. I'm not actually sure if those
were before or after 2.0, it was so long ago.

I haven't followed AGL, so I don't know, nor do I participate there
