 ;;; Change Log:
 
-;; From 1.9 to 1.91
-;;
-;; - Fixed a bug (introduced in 1.9) so now files can be marked for
-;;   deletion again, by deleting their whole filename.
-
-;; From 1.8 to 1.9
-;;
-;; - Another alternative way of editing permissions allowed, see
-;;   `wdired-allow-to-change-permissions' for details.
-;;
-;; - Now wdired doesn't rely on regexp so much. As a consequence of
-;;   this, you can add newlines to filenames and symlinks targets
-;;   (although this is not very usual, IMHO). Please note that dired
-;;   (at least in Emacs 21.1 and previous) does not work very well
-;;   with filenames with newlines in them, so RET is deactivated in
-;;   wdired mode. But you can activate it if you want.
-;;
-;; - Now `upcase-word' `capitalize-word' and `downcase-word' are not
-;;   advised to work better with wdired mode, but the keys bound to
-;;   them use wdired versions of those commands.
-;;
-;; - Now "undo" actions are not inherited from wdired mode when
-;;   changing to dired mode.
-;;
-;; - Code and documentation cleanups.
-;;
-;; - Fixed a bug that was making wdired to fail on users with
-;;   `dired-backup-overwrite' set to t.
-;;
-;; - C-c C-[ now abort changes.
-
-;; From 1.7 to 1.8
-;;
-;; - Now permission (access-control) bits of the files can be changed.
-;;   Please see the commentary section and the custom variable
-;;   `wdired-allow-to-change-permissions' for details.
-;;
-;; - Added another possible value for the variable
-;;   `wdired-always-move-to-filename-beginning', useful to change
-;;   permission bits of several files without the cursor jumping to
-;;   filenames when changing lines.
-
-;; From 0.1 to 1.7
-
-;; - I've moved the list of changes to another file, because it was
-;;   huge. Ask me for it or search older versions in google.
-
-;;; TODO:
-
-;; - Make it to work in XEmacs. Any volunteer?
+;; Google is your friend (previous versions with complete changelogs
+;; were posted to gnu.emacs.sources)
