- Update random to version 1.2.0 revision 5.
  # 1.2.0

1. Breaking change which mostly maintains backwards compatibility, see
     "Breaking Changes" below.
  2. Support for monadic generators e.g. [mwc-random](https://hackage.haskell.org/package/mwc-random).
  3. Monadic adapters for pure generators (providing a uniform monadic
     interface to pure and monadic generators).
  4. Faster in all cases except one by more than x18 (N.B. x18 not 18%) and
     some cases (depending on the type) faster by more than x1000 - see
     below for benchmarks.
  5. Passes a large number of random number test suites:
     * [dieharder](http://webhome.phy.duke.edu/~rgb/General/dieharder.php "venerable")
     * [TestU01 (SmallCrush, Crush, BigCrush)](http://simul.iro.umontreal.ca/testu01/tu01.html "venerable")
     * [PractRand](http://pracrand.sourceforge.net/ "active")
     * [gjrand](http://gjrand.sourceforge.net/ "active")
     * See [random-quality](https://github.com/tweag/random-quality)
       for details on how to do this yourself.
  6. Better quality split as judged by these
  	[tests](https://www.cambridge.org/core/journals/journal-of-functional-programming/article/evaluation-of-splittable-pseudorandom-generators/3EBAA9F14939C5BB5560E32D1A132637). Again
  	see [random-quality](https://github.com/tweag/random-quality) for
  	details on how to do this yourself.
  7. Unbiased generation of ranges.
  8. Updated tests and benchmarks.
  9. [Continuous integration](https://travis-ci.org/github/haskell/random).

### Breaking Changes

Version 1.2.0 introduces these breaking changes:

* requires `base >= 4.8` (GHC-7.10)
  * `StdGen` is no longer an instance of `Read`
  * `randomIO` and `randomRIO` were extracted from the `Random` class into
    separate functions

In addition, there may be import clashes with new functions, e.g. `uniform` and
  `uniformR`.

### Deprecations

Version 1.2.0 introduces `genWord64`, `genWord32` and similar methods to the
  `RandomGen` class. The significantly slower method `next` and its companion
  `genRange` are now deprecated.

### Issues Addressed

Issue Number | Description | Comment
  --------------|-------------|--------
   [25](https://github.com/haskell/random/issues/25) | The seeds generated by split are not independent | Fixed: changed algorithm to SplitMix, which provides a robust split operation
   [26](https://github.com/haskell/random/issues/26) | Add Random instances for tuples | Addressed: added `Uniform` instances for up to 6-tuples
   [44](https://github.com/haskell/random/issues/44) | Add Random instance for Natural | Addressed: added UniformRange instance for Natural
   [51](https://github.com/haskell/random/issues/51) | Very low throughput | Fixed: see benchmarks below
   [53](https://github.com/haskell/random/issues/53) | incorrect distribution of randomR for floating-point numbers | (\*)
   [55](https://github.com/haskell/random/issues/55) | System/Random.hs:43:1: warning: [-Wtabs] | Fixed: No more tabs
   [58](https://github.com/haskell/random/issues/58) | Why does random for Float and Double produce exactly 24 or 53 bits? | (\*)
   [59](https://github.com/haskell/random/issues/59) | read :: StdGen fails for strings longer than 6 | Addressed: StdGen is no longer an instance of Read

#### Comments

(\*) 1.2 samples more bits but does not sample every `Float` or
  `Double`. There are methods to do this but they have some downsides;
  see [here](https://github.com/idontgetoutmuch/random/issues/105) for a
  fuller discussion.

## Benchmarks

Here are some benchmarks run on a 3.1 GHz Intel Core i7. The full
  benchmarks can be run using e.g. `stack bench`. The benchmarks are
  measured in milliseconds per 100,000 generations. In some cases, the
  performance is over x1000 times better; the minimum performance
  increase for the types listed below is more than x36.

Name       | 1.1 Mean | 1.2 Mean
  ------------|----------|----------
   Float      |   27.819 |    0.305
   Double     |   50.644 |    0.328
   Integer    |   42.332 |    0.332
   Word       |   40.739 |    0.027
   Int        |   43.847 |    0.028
   Char       |   17.009 |    0.462
   Bool       |   17.542 |    0.027
