BREAKING CHANGE: With 26.x support dropped, I've dropped: - doom-plist-delete: use map-delete instead - plist-delete!: use cl-callf + map-delete instead - doplist: use (cl-loop for X on PLIST by #'cddr ...) instead These were removed as part of an ongoing effort to eliminate redundancies with built-in packages and reduce Doom's overall footprint.
