+
+	* progmodes/fortran.el (fortran-mode-syntax-table):
+	* progmodes/f90.el (f90-mode-syntax-table):
+	Set % to punctuation.  (Bug#8820)
+	(f90-find-tag-default): Remove, no longer needed.
+
+2011-06-12  Daniel Colascione  <dan.colascione@gmail.com>
+
+	* emacs-lisp/syntax.el (syntax-ppss): Clarify which items are invalid.
+
+2011-06-11  Chong Yidong  <cyd@stupidchicken.com>
+
+	* image.el (image-animated-p): Return animation delay in seconds.
+	Avoid bit manipulation in Lisp; use `delay' entry in the metadata.
+	(image-animate-timeout): Remove DELAY argument.  Don't assume
+	every subimage has the same delay; get it from image-animated-p.
+	(image-animate): Caller changed.
