+- Issue #25626: Change three zlib functions to accept sizes that fit in
+ Py_ssize_t, but internally cap those sizes to UINT_MAX. This resolves a
+ regression in 3.5 where GzipFile.read() failed to read chunks larger than 2

+ parameter, the zlib.decompress() bufsize parameter, and the
+ zlib.Decompress.flush() length parameter.

+IDLE
+----
+
+- 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.
+

++ dialog rather than a separate dialog. The former tabs are now a sorted

+- 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.
+ Strings, comments, keywords, ... are still green, red, orange, ... .
+ To use it with IDLEs released before November 2015, hit the
+ 'Save as New Custom Theme' button and enter a new name,
+ such as 'Custom Dark'. The custom theme will work with any IDLE
+ release, and can be modified.
+
+- Issue #25224: README.txt is now an idlelib index for IDLE developers and
+ curious users. The previous user content is now in the IDLE doc chapter.

+ at the top of the screen.

+
+- Issue #16893: Replace help.txt with help.html for Idle doc display.
+ The new idlelib/help.html is rstripped Doc/build/html/library/idle.html.

+ The tkinter html viewer that works for this file was written by Rose Roseman.
+ The now unused EditorWindow.HelpDialog class and helt.txt file are deprecated.
+
+- Issue #24199: Deprecate unused idlelib.idlever with possible removal in 3.6.
+
