[ANN] IPython 0.11 is officially out

[Fernando Perez]

Hi all,

on behalf of the IPython development team, I'm thrilled to announce,
after more than two years of development work, the official release of
IPython 0.11.

This release brings a long list of improvements and new features
(along with hopefully few new bugs). We have completely refactored
IPython, making it a much more friendly project to participate in by
having better separated and organized internals. We hope you will not
only use the new tools and libraries, but also join us with new ideas
and development.

After this very long development effort, we hope to make a few
stabilization releases at a quicker pace, where we iron out the kinks
in the new APIs and complete some remaining internal cleanup work. We
will then make a (long awaited) IPython 1.0 release with these stable
APIs.

*Downloads*
Download links and instructions are at: http://ipython.org/download.html
And IPython is also on PyPI: http://pypi.python.org/pypi/ipython

Those contain a built version of the HTML docs; if you want pure
source downloads with no docs, those are available on github:

Tarball: https://github.com/ipython/ipython/tarball/rel-0.11
Zipball: https://github.com/ipython/ipython/zipball/rel-0.11

* Features *
Here is a quick listing of the major new features:

- Standalone Qt console
- High-level parallel computing with ZeroMQ
- New model for GUI/plotting support in the terminal
- A two-process architecture
- Fully refactored internal project structure
- Vim integration
- Integration into Microsoft Visual Studio
- Improved unicode support
- Python 3 support
- New profile model
- SQLite storage for history
- New configuration system
- Pasting of code with prompts

And many more...

We closed over 500 tickets, merged over 200 pull requests, and more
than 60 people contributed over 2200 commits for the final release.
Please see our release notes for the full details on everything about
this release: https://github.com/ipython/ipython/zipball/rel-0.11

You can see a talk about this release that was presented at the Scipy 2011
conference:

For reference, the slides that go along with it are here:

And there's an excellent blog post, written by Chris Fonnesbeck, providing
a visual tour of our new features:

As usual, if you find any problem, please file a ticket --or even
better, a pull request fixing it-- on our github issues site
(https://github.com/ipython/ipython/issues/).

Many thanks to all who contributed!

Fernando, on behalf of the IPython development team.

And the best thing is: IPython 0.11 is not compatible to 0.10 so if you
had your own customized ipythonrc you can start from scratch.

The documentation[1] says "If you are upgrading to version 0.11 of
IPython, you will need to migrate your old ipythonrc or ipy_user_conf.py
configuration files to the new system. Read on for information on how to
do this." Unfortunately there is no more mentioning of "migration", so
the developers' approach seems to be: "read all about the new
configuration system and see if you can somehow duplicate your old
ipythonrc settings. Good luck!".

By the way: "configuration object", "applications", "configurables",
"singletons", ... Am I really supposed to understand all this?

Or you can ask nicely on ipython-user, and we can help you migrate your old
ipythonrc.

You can basically start with the ipython_config.py that is generated the first
time and edit it. It is fully commented and demonstrates every configurable
option with the defaults commented out. You just uncomment the appropriate lines
and put in your values.

You are right that the HOWTO migrate documentation is missing. It's an oversight
that you can help remedy.
