1.2.1.3

* Bug fix: As it turns out, moving the literal rewrite rules to simplifier 
  phase 2 does not prevent competition with the `unpack` rule, which is
  also active in this phase. Unfortunately this was hidden due to a silly
  test environment mistake. Moving literal rules back to phase 1 finally
  fixes GHC Trac #10528 correctly.

1.2.1.2

* Bug fix: Run literal rewrite rules in simplifier phase 2.
  The behavior of the simplifier changed in GHC 7.10.2,
  causing these rules to fail to fire, leading to poor code generation
  and long compilation times. See
  [GHC Trac #10528](https://ghc.haskell.org/trac/ghc/ticket/10528).

1.2.1.1

* Expose unpackCString#, which you should never use.

1.2.1.0

* Added Binary instances for both Text types. (If you have previously
  been using the text-binary package to get a Binary instance, it is
  now obsolete.)

1.2.0.6

* Fixed a space leak in UTF-8 decoding

1.2.0.5

* Feature parity: repeat, cycle, iterate are now implemented for lazy
  Text, and the Data instance is more complete

* Build speed: an inliner space explosion has been fixed with toCaseFold

* Bug fix: encoding Int to a Builder would infinite-loop if the
  integer-simple package was used

* Deprecation: OnEncodeError and EncodeError are deprecated, as they
  are never used

* Internals: some types that are used internally in fusion-related
  functions have moved around, been renamed, or been deleted (we don't
  bump the major version if .Internal modules change)

* Spec compliance: toCaseFold now follows the Unicode 7.0 spec
  (updated from 6.3)

1.2.0.4

* Fixed an incompatibility with base < 4.5

1.2.0.3

* Update formatRealFloat to correspond to the definition in versions
  of base newer than 4.5 (https://github.com/bos/text/issues/105)

1.2.0.2

* Bumped lower bound on deepseq to 1.4 for compatibility with the
  upcoming GHC 7.10

1.2.0.1

* Fixed a buffer overflow in rendering of large Integers
  (https://github.com/bos/text/issues/99)

1.2.0.0

* Fixed an integer overflow in the replace function
  (https://github.com/bos/text/issues/81)

* Fixed a hang in lazy decodeUtf8With
  (https://github.com/bos/text/issues/87)

* Reduced codegen bloat caused by use of empty and single-character
  literals

* Added an instance of IsList for GHC 7.8 and above

1.1.1.0

* The Data.Data instance now allows gunfold to work, via a virtual
  pack constructor

* dropEnd, takeEnd: new functions

* Comparing the length of a Text against a number can now
  short-circuit in more cases

1.1.0.1

* streamDecodeUtf8: fixed gh-70, did not return all unconsumed bytes
  in single-byte chunks

1.1.0.0

* encodeUtf8: Performance is improved by up to 4x.

* encodeUtf8Builder, encodeUtf8BuilderEscaped: new functions,
  available only if bytestring >= 0.10.4.0 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!

1.0.0.1

* decodeUtf8: Fixed a regression that caused us to incorrectly
  identify truncated UTF-8 as valid (gh-61)

1.0.0.0

* 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
