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+

11.2.0.3
