Exit Emacs 25. Start Emacs 24.5 again. The desktop fails to load. This is a Bad Thing. Diagnosis --------- Emacs 25 has read a version 206 .desktop file, but written a version 208 file on termination. Emacs 24 cannot execute this version. There was no yes-or-no-p asking "are you sure you want to convert your desktop to a format incompatible with previous Emacs versions?". Manually restoring a .desktop to version 206 is fraught with difficulties, even for somebody (myself) who understands the issues reasonably well, and has an old version of .desktop saved "just in case". Recommendation -------------- Emacs 25, having loaded a version 206 .desktop, should save it in the same format until the user has positively consented to it being converted to version 208. -- Alan Mackenzie (Nuremberg, Germany).
