[flud-devel] announcing zfec v1.2.0

Folks:

I've uploaded zfec v1.2.0 to the Python Package Index.

http://pypi.python.org/pypi/zfec

The big changes from zfec 1.1 that you have to specially pay  
attention to:

  * I fixed a bug in the "easyfec" API, in which that API would do  
padding incorrectly.  The "easyfec" API is not the primary API, it is  
an optional wrapper around the basic API which does offers a slightly  
more abstract interface (the input data is a string instead of a list  
of strings), at a cost in performance.  I also changed the easyfec  
API to be harder to misuse -- if you were previously using the  
easyfec API, then please examine the new docstring and change the way  
that you call it.

  * I stopped copying in bits of code from other projects and instead  
have started depending on those other projects, namely argparse and  
pyutil.

Other changes:

  * Greg Hazel contributed a patch to make zfec compile with the  
Microsoft Visual Studio tool, which apparently will never support  
C99.  :-(  So now zfec is C89-compatible.  Thanks, Greg!

  * more detailed and human-friendly exception messages if you pass  
wrongly shaped inputs (e.g. padding mistakes)

  * add benchmarks of easyfec vs. fec -- fec can be several times as  
fast (depending on the size of the inputs) on my machine!

  * add unit tests, especially unit tests for easyfec

  * various improvements of the code which don't change functionality  
or performance

Regards,

Zooko
