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
