;; - Added `fast-lock-get-syntactic-properties'
;; - Renamed `fast-lock-set-face-properties' to `fast-lock-add-properties'
;; - Made `fast-lock-add-properties' add syntactic and face fontification data
+;; 3.13--3.14:
+;; - Made `fast-lock-cache-name' cope with `windowsnt' (Geoff Voelker fix)
+;; - Made `fast-lock-verbose' use `other' widget (Andreas Schwab fix)
+;; - Used `with-temp-message' where possible to make messages temporary.
