 -What's New in Idle 3.4.4?
 +What's New in IDLE 3.5.1?
  =========================
- *Release date: 2015-09-13*
 -*Release date: 2015-12-20*
++*Release date: 2015-12-06*
+ 
+ - Issue 15348: Stop the debugger engine (normally in a user process)
+   before closing the debugger window (running in the IDLE process).
+   This prevents the RuntimeErrors that were being caught and ignored.
+ 
+ - Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
+   debugger is active (15347); b) closing the debugger with the [X] button
+   (15348); and c) activating the debugger when already active (24455).
+   The patch by Mark Roseman does this by making two changes.
+   1. Suspend and resume the gui.interaction method with the tcl vwait
+   mechanism intended for this purpose (instead of root.mainloop & .quit).
+   2. In gui.run, allow any existing interaction to terminate first.
+ 
+ - Change 'The program' to 'Your program' in an IDLE 'kill program?' message
+   to make it clearer that the program referred to is the currently running
+   user program, not IDLE itself.
+ 
+ - Issue #24750: Improve the appearance of the IDLE editor window status bar.
+   Patch by Mark Roseman.
+ 
+ - Issue #25313: Change the handling of new built-in text color themes to better
+   address the compatibility problem introduced by the addition of IDLE Dark.
+   Consistently use the revised idleConf.CurrentTheme everywhere in idlelib.
+ 
+ - Issue #24782: Extension configuration is now a tab in the IDLE Preferences
+   dialog rather than a separate dialog.   The former tabs are now a sorted
+   list.  Patch by Mark Roseman.
+ 
+ - Issue #22726: Re-activate the config dialog help button with some content
+   about the other buttons and the new IDLE Dark theme.
  
  - Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme.
    It is more or less IDLE Classic inverted, with a cobalt blue background.

  - Issue #24790: Remove extraneous code (which also create 2 & 3 conflicts).
