Hi All,

I'm pleased to announce the release of testfixtures 3.0.0. The big 
change for this release is that testfixtures now supports Python 2.6, 
2.7, 3.2 and 3.3!

As a result, some changes have been made to TempDirectory to support 
encoding and decoding. There's also a nice little addition of an 
optional prefix to the message generated when comparisons fail:

>>> from testfixtures import compare
>>> compare(1, 2, prefix='wrong number of orders')
Traceback (most recent call last):
AssertionError: wrong number of orders: 1 != 2

The means that you still get the rich comparison feedback offered by 
compare, but can also add more information to make any failure more 
easily understandable without having to dig into the source.

Other than that, there have been a couple of minor bug fixes.

If you haven't bumped into it already, testfixtures is a collection of 
helpers for writing succinct unit tests including help for:

- Comparing objects and sequences

Better feedback when the results aren't as you expected along with 
support for comparison of objects that don't normally support comparison.

- Mocking out objects and methods

Easy to use ways of stubbing out objects, classes or individual methods 
for both doc tests and unit tests. Special helpers are provided for 
testing with dates and times.

- Testing logging

Helpers for capturing logging output in both doc tests and unit tests.

- Testing stream output

Helpers for capturing stream output, such as that from print statements, 
and making assertion about it.

- Testing with files and directories

Support for creating and checking files and directories in sandboxes for 
both doc tests and unit tests.

- Testing exceptions

Easy to use ways of checking that a certain exception is raised, even 
down the to the parameters the exception is raised with.

The package is on PyPI and a full list of all the links to docs, issue 
trackers and the like can be found here:
