1−1.2.2.1

2−

3−* The switch to `integer-pure` in 1.2.2.0 was apparently mistaken.

4− The build flag has been renamed accordingly. Your army of diligent

5− maintainers apologizes for the churn.

6−

7−* Spec compliance: toCaseFold now follows the Unicode 8.0 spec

8− (updated from 7.0)

9−

10−* An STG lint error has been fixed

11−

12−1.2.2.0

13−

14−* The `integer-simple` package, upon which this package optionally

15− depended, has been replaced with `integer-pure`. The build flag has

16− been renamed accordingly.

17−

18−* Bug fix: For the `Binary` instance, If UTF-8 decoding fails during a

19− `get`, the error is propagated via `fail` instead of an uncatchable

20− crash.

21−

22−* New function: `takeWhileEnd`

23−

24−* New instances for the `Text` types:

25− * if `base` >= 4.7: `PrintfArg`

26− * if `base` >= 4.9: `Semigroup`

27−

28−1.2.1.3

29−

30−* Bug fix: As it turns out, moving the literal rewrite rules to simplifier

31− phase 2 does not prevent competition with the `unpack` rule, which is

32− also active in this phase. Unfortunately this was hidden due to a silly

33− test environment mistake. Moving literal rules back to phase 1 finally

34− fixes GHC Trac #10528 correctly.

35−

36−1.2.1.2

37−

38−* Bug fix: Run literal rewrite rules in simplifier phase 2.

39− The behavior of the simplifier changed in GHC 7.10.2,

40− causing these rules to fail to fire, leading to poor code generation

41− and long compilation times. See

42− [GHC Trac #10528](https://ghc.haskell.org/trac/ghc/ticket/10528).

43−

44−1.2.1.1

45−

46−* Expose unpackCString#, which you should never use.

47−

48−1.2.1.0

49−

50−* Added Binary instances for both Text types. (If you have previously

51− been using the text-binary package to get a Binary instance, it is

52− now obsolete.)

53−

54−1.2.0.6

55−

56−* Fixed a space leak in UTF-8 decoding

57−

58−1.2.0.5

59−

60−* Feature parity: repeat, cycle, iterate are now implemented for lazy

61− Text, and the Data instance is more complete

62−

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

64−

65−* Bug fix: encoding Int to a Builder would infinite-loop if the

66− integer-simple package was used

67−

68−* Deprecation: OnEncodeError and EncodeError are deprecated, as they

69− are never used

70−

71−* Internals: some types that are used internally in fusion-related

72− functions have moved around, been renamed, or been deleted (we don't

73− bump the major version if .Internal modules change)

74−

75−* Spec compliance: toCaseFold now follows the Unicode 7.0 spec

76− (updated from 6.3)

77−

78−1.2.0.4

79−

80−* Fixed an incompatibility with base < 4.5

81−

82−1.2.0.3

83−

84−* Update formatRealFloat to correspond to the definition in versions

85− of base newer than 4.5 (https://github.com/bos/text/issues/105)

86−

87−1.2.0.2

88−

89−* Bumped lower bound on deepseq to 1.4 for compatibility with the

90− upcoming GHC 7.10

91−

92−1.2.0.1

93−

94−* Fixed a buffer overflow in rendering of large Integers

95− (https://github.com/bos/text/issues/99)

96−

97−1.2.0.0

98−

99−* Fixed an integer overflow in the replace function

100− (https://github.com/bos/text/issues/81)

101−

102−* Fixed a hang in lazy decodeUtf8With

103− (https://github.com/bos/text/issues/87)

104−

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

106− literals

107−

108−* Added an instance of IsList for GHC 7.8 and above

109−

110−1.1.1.0

111−

112−* The Data.Data instance now allows gunfold to work, via a virtual

113− pack constructor

114−

115−* dropEnd, takeEnd: new functions

116−

117−* Comparing the length of a Text against a number can now

118− short-circuit in more cases

119−

120−1.1.0.1

121−

122−* streamDecodeUtf8: fixed gh-70, did not return all unconsumed bytes

123− in single-byte chunks

124−

125−1.1.0.0

126−

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

128−

129−* encodeUtf8Builder, encodeUtf8BuilderEscaped: new functions,

130− available only if bytestring >= 0.10.4.0 is installed, that allow

131− very fast and flexible encoding of a Text value to a bytestring

132− Builder.

133−

134− As an example of the performance gain to be had, the

135− encodeUtf8BuilderEscaped function helps to double the speed of JSON

136− encoding in the latest version of aeson! (Note: if all you need is a

137− plain ByteString, encodeUtf8 is still the faster way to go.)

138−

139−* All of the internal module hierarchy is now publicly exposed. If a

140− module is in the .Internal hierarchy, or is documented as internal,

141− use at your own risk - there are no API stability guarantees for

142− internal modules!

143−

144−1.0.0.1

145−

146−* decodeUtf8: Fixed a regression that caused us to incorrectly

147− identify truncated UTF-8 as valid (gh-61)

148−

149−1.0.0.0

150−

151−* Added support for Unicode 6.3.0 to case conversion functions

152−

153−* New function toTitle converts words in a string to title case

154−

155−* New functions peekCStringLen and withCStringLen simplify

156− interoperability with C functionns

157−

158−* Added support for decoding UTF-8 in stream-friendly fashion

159−

160−* Fixed a bug in mapAccumL

161−

162−* Added trusted Haskell support

163−

164−* Removed support for GHC 6.10 (released in 2008) and older

38+ * String literals are now converted directly from the format in

40+ transformation through 'String', and without inlining of

41+ conversion code at each site where a string literal is declared.
