[chemfp] 1.1b4 is available

[Andrew Dalke]

Hi all,

  The current chemfp code is stable. As is sadly usual though, the
documentation lags. I'll be working on that over the next couple of
weeks while I travel and go to OpenEye's CUP conference.

  In the meanwhile, I've put a fresh beta release on Google Code.
It's at

  http://code.google.com/p/chem-fingerprints/downloads/detail?name=chemfp-1.1b4.tar.gz

See the CHANGELOG ( http://code.google.com/p/chem-fingerprints/source/browse/CHANGELOG )
for details. The highlights are 

  - Support for symmetric searches (uses more memory to double performance)

  - New, faster popcount algorithms, including hardware POPCNT for machines which support it.

  - OpenMP support for searches with a query arena (single fingerprint searches are not affected)

  - Added support for RDKit's Morgan fingerprints and OpenEye's Tree and Circular fingerprints.

  - New search results API to simplify dealing with hitlists, improve memory use, and improve performance

Let me know of any problems, or anything you specifically want documented.
