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+
1581.2.0.5
259
360* Feature parity: repeat, cycle, iterate are now implemented for lazy
