According to my study, I think there is no big impacts for > users, is it right? Hi Nancy, 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. > Will AGL adopt the weston 5.0 or other weston version in their new AGL > version sunch as AGL 7.0? I haven't followed AGL, so I don't know, nor do I participate there currently. Thanks, pq
