Changelog for text- * encodeUtf8: Performance is improved by up to 4x. * encodeUtf8Builder, encodeUtf8BuilderEscaped: new functions, available only if bytestring >= is installed, that allow very fast and flexible encoding of a Text value to a bytestring Builder. As an example of the performance gain to be had, the encodeUtf8BuilderEscaped function helps to double the speed of JSON encoding in the latest version of aeson! (Note: if all you need is a plain ByteString, encodeUtf8 is still the faster way to go.) * All of the internal module hierarchy is now publicly exposed. If a module is in the .Internal hierarchy, or is documented as internal, use at your own risk - there are no API stability guarantees for internal modules! * decodeUtf8: Fixed a regression that caused us to incorrectly identify truncated UTF-8 as valid (gh-61) * Added support for Unicode 6.3.0 to case conversion functions * New function toTitle converts words in a string to title case * New functions peekCStringLen and withCStringLen simplify interoperability with C functionns * Added support for decoding UTF-8 in stream-friendly fashion * Fixed a bug in mapAccumL * Added trusted Haskell support * Removed support for GHC 6.10 (released in 2008) and older
