Hi all,

I'm glad to announce that IPython 0.6.4 is finally out. You can download it 
from the usual place:


I've provided RPMs for Python 2.2 and 2.3, plus source downloads (.tar.gz and 

Debian, Fink and BSD packages for this version should be coming soon, as the 
respective maintainers (many thanks to Jack Moffit, Andrea Riciputi and Dryice 
Liu) have the time to follow their packaging procedures.

Many thanks to Enthought for their continued hosting support for IPython, and 
to all the users who contributed ideas, fixes and reports.

IMPORTANT NOTE: Unless any important bugs are found, this version will likely 
be the last ipython release for quite some time.  I intend to (finally) start 
a major internal cleanup, as described in:


This process will likely take a while; even though it's relatively 
straightforward, there is a _lot_ of code to go through.  In a few weeks, I 
will probably open a separate CVS branch for this, so that I can still fix 
bugs for version 0.6.4 in CVS HEAD if they are found.  Needless to say, any 
volunteers are welcome to help :)

Once the new branch becomes reasonably stable, it will be released, and I hope 
this will soon after lead to an official '1.0' release for ipython.

Now, on to the usual summary of changes in IPython 0.6.4 vs 0.6.3.  As always, 
the complete NEWS file can be found at http://ipython.scipy.org/NEWS, and the 
whole ChangeLog at http://ipython.scipy.org/ChangeLog.

- License changed to BSD: IPython is now fully licensed under the terms of the 
BSD license (except for a few MIT-licensed files which have always been there; 
the MIT license is very similar to BSD).

- Changed the explicit magic escape from @ to %, to conform with the 
introduction of Python @decorators in Python 2.4.  IPython 0.6.4 should be 
100% compatible with Python 2.4.

- Many small improvements which mainly matter to users of the matplotlib 
support (via -pylab).  These fix a number of problems, crashes and annoyances 
present in 0.6.3.

- Small fixes and hardenings against crashes which could be caused by buggy 
third-party code run from within ipython.  There are currently no known 
ipython crash cases.

Enjoy, and as usual please report any problems.
