 code relying (whether intentionally or accidentally) on old behavior.
 
+ - SF bug 734869: Fixed a compiler bug that caused a fatal error when
+ compiling a list comprehension that contained another list comprehension
+ embedded in a lambda expression.

 - SF bug 705231: builtin pow() no longer lets the platform C pow()
 raise -1.0 to integer powers, because (at least) glibc gets it wrong

+ - SF bug 759227: A new-style class that implements __nonzero__() must
+ return a bool or int (but not an int subclass) from that method. This
+ matches the restriction on classic classes.

 - The encoding attribute has been added for file objects, and set to
 the terminal encoding on Unix and Windows.

 timeouts to be handled separately from other socket errors.
 
+ - SF bug 751276: cPickle has fixed to propagate exceptions raised in
+ user code. In earlier versions, cPickle caught and ignored any
+ exception when it performed operations that it expected to raise
+ specific exceptions like AttributeError.
+ 
+ - cPickle Pickler and Unpickler objects now participate in garbage
+ collection.

 - mimetools.choose_boundary() could return duplicate strings at times,
 especially likely on Windows. The strings returned are now guaranteed

- - ZipFile.testzip() now only traps BadZipfile exceptions. Previously,
- a bare except caught to much and reported all errors as a problem
- in the archive.
- 
- - The logging module now has a new function, makeLogRecord() making
- LogHandler easier to interact with DatagramHandler and SocketHandler.
- 
 - For compatibility with doctests created before 2.3, if an expected
 output block consists solely of "1" and the actual output block

 - The threading module has new functions settrace() and setprofile()
 that cooperate with the functions of the same name in the sys
 module. A function registered with the threading module will
! be used for all threads it creates.

+ - Added a new module: trace (documentation missing). This module used
+ to be distributed in Tools/scripts. It uses sys.settrace() to trace
+ code execution -- either function calls or individual lines. It can
+ generate tracing output during execution or a post-mortem report of
+ code coverage.

 - The threading module has new functions settrace() and setprofile()
 that cooperate with the functions of the same name in the sys
 module. A function registered with the threading module will
! be used for all threads it creates. The new trace module uses this
! to provide tracing for code running in threads.
