Hi all,
I have released IPython 0.7.1, which is mainly a bugfix release over 0.7.0.
As expected in that release, given the large changes made, some problems
inevitably appeared. I believe all regressions and known bugs have been
fixed, along with some useful new features.
This release marks the

I've just made the 0.6.14 release of IPython, mostly to fix the

listed as writable. Yet, nowhere does it say _how_ to write to it. I am
trying to do a run-time modification of a function's closure, where I want to
modify the value of one of the variables in the closure. B
