Hi,

1) The most recent release I could find was about a year old (http://
code.google.com/p/unladen-swallow/wiki/Release2009Q3). Has there been
any new releases since then? If so, do you have any performance &
memory consumption data for the latest release? I'm mainly interested
in using Unladen Swallow for Django.

2) Unladen Swallow is targeted for integration with Python 3. Does it
work with 2.6? If so, how to do that?

3) Does Unladen Swallow work with greenlets or greenlet-like libraries
such as gevent?

Thanks.

There has not been another release.

Unladen Swallow is a branch off of Python 2.6.

I have no idea.

While apparently no official performance data has been released, a
simple comparison between SVN HEAD of unladen swallow and stock Python
2.7 gives the following:

$ ./perf.py -b django ~/cpython/release2.7-maint/python ~/unladen/
__svn__/python
Running django...

By the way, the benchmark scripts are maintained at http://hg.python.org/benchmarks/

Good luck
