New in this release: - Substantial performance improvements. - Bug fixes, and better quality assurance via automated QuickCheck and HPC tests and coverage. - An even nicer API than before. The text library provides an efficient packed, immutable Unicode text type (both strict and lazy), with a powerful loop fusion optimization framework. The 'Text' type represents Unicode character strings, in a time and space-efficient manner. This package provides text processing capabilities that are optimized for performance critical use, both in terms of large data quantities and high speed. The text package provides character-encoding, type-safe case conversion via whole-string case conversion functions. It also provides a range of functions for converting Text values to and from ByteStrings, using several standard encodings (see the text-icu package for a much larger variety of encoding functions). Efficient locale-sensitive support for text I/O is also supported. http://www.serpentine.com/blog/2010/09/01/major-version-of-the-haskell-text-...
