[Blog copy of the announcement

I just pushed it to bitbucket <http://bitbucket.org/bos/text> and
and you can install it from the text site on
Hackage<http://hackage.haskell.org/package/text> in
the usual way:

cabal update
cabal install text

What's in this release?


   New functions for reading integers and floating point
   an oft-requested feature. They're fast, too: they range from parity with
   their bytestring counterparts, to up to 4 times faster. You can expect to
   parse 3 to 4 million Int values per second out of a text file, or up 2
   million Double values per second. They're also easy to use, give error
   messages, and come in strict and lazy variants.

   UTF-8 decoding and encoding are now very
   They're up to 9x faster than they were, and close to the performance of pure
   C UTF-8 decoding and encoding.

   The Eq and Ord instances are also now very fast, up to 5x faster than
   They're now faster than the bytestring instances.

   Several other common functions received drive-by performance improvements

   Better protection against rare crashes on really huge volumes of data.
