+
+### Important notice
+
+#### Posting tweets with minibuffer is obsolete now.
+
+There's two way to edit and post tweets in twittering-mode: with
+minibuffer (existing way), and with pop-up buffer (new feature!).  You
+can choose it by setting the variable
+`twittering-update-status-function`. Currently its default value is
+the existing way, `twittering-update-status-from-minibuffer`, but in
+next release it will be changed to the new way
+`twittering-update-status-from-pop-up-buffer`.
+
+We recommend you to use the new feature by adding following code to
+your `.emacs`:
+
+    (setq twittering-update-status-function
+          'twittering-update-status-from-pop-up-buffer)
+
+The new feature, pop-up buffer, has several advantages over the
+existing way.
+
+* Not conflicting with input methods.
+* Much less risk of posting halfway typed tweets by error.
+* Visual assertion of length of tweets.
+
+### Improvements
+
+* Introduction of a concept 'timeline spec'.
+* Pop-up buffer to edit and post tweets.
+* Auto proxy setup with environment variables (http_proxy, HTTP_PROXY)
+* Support for official ReTweet.
+* Added some format specifiers of tweets.
+* Displaying image files without temporary files.
+* ...
+
+### Bug fixes

+  * twittering-cert-file
+  * twittering-ensure-ca-cert
+* Fix URI (percent) encoding (thanks to IMAI Toshiyuki).
