Update to pidgin-2.4.2.

* The typing notification in the conversation history can be disabled or
  customized (font, color etc.) in .gtkrc-2.0.
* Added a plugin (not installed by default) which adds a Send button back to
  the conversation window. People without physical keyboards have a hard time
  with the lack of the button.
* Clicking on the buddyicon in the conversation window toggles the size of the
  icon between small and large.
* The settings of a chat (e.g. Handle in an XMPP chat, or Exchange in an AIM
  chat) can be edited from its context menu in the buddy list.
* Add a "Present conversation window" preference to the Message Notification
  plugin; the "Raise conversation window" option does not unminimize windows
  or draw attention to them when they are on other workspaces--the "Present"
  option should.
* Add a preference to set Escape as the keyboard shortcut for closing the
  conversation window.
* Add an option in the context menu to disable smileys in the selected text
  in the conversation history/log viewer. This should help people who
  regularly paste code in conversations.
* Add a preference to choose the minimum size of the text input area in lines.
* Moved the "Local alias" field in the Modify Account dialog to be below the
  "User Options" heading on the "Basic" tab.
* Number of room occupants is now shown in chat tooltips where possible
