------------------------------------------------------------------- Sun Feb 4 16:26:32 UTC 2024 - Peter Simons <psimons@suse.com> - Update random to version 1.2.1.2. Upstream has not updated the file "CHANGELOG.md" since the last release. ------------------------------------------------------------------- Sat Sep 30 20:57:11 UTC 2023 - Peter Simons <psimons@suse.com> - Update random to version 1.2.1.1 revision 1. Upstream has revised the Cabal build instructions on Hackage. ------------------------------------------------------------------- Thu Mar 30 17:08:00 UTC 2023 - Peter Simons <psimons@suse.com> - Updated spec file to conform with ghc-rpm-macros-2.5.2. ------------------------------------------------------------------- Mon May 9 02:32:03 UTC 2022 - Peter Simons <psimons@suse.com> - Update random to version 1.2.1.1. Upstream has not updated the file "CHANGELOG.md" since the last release. ------------------------------------------------------------------- Mon Sep 20 07:13:14 UTC 2021 - psimons@suse.com - Update random to version 1.2.1. # 1.2.1 * Fix support for ghc-9.2 [#99](https://github.com/haskell/random/pull/99) * Fix performance regression for ghc-9.0 [#101](https://github.com/haskell/random/pull/101) * Add `uniformEnumM` and `uniformEnumRM` * Add `initStdGen` [#103](https://github.com/haskell/random/pull/103) * Add `globalStdGen` [#117](https://github.com/haskell/random/pull/117) * Add `runStateGenST_` * Ensure that default implementation of `ShortByteString` generation uses unpinned memory. [#116](https://github.com/haskell/random/pull/116) * Fix [#54](https://github.com/haskell/random/issues/54) with [#68](https://github.com/haskell/random/pull/68) - if exactly one value in the range of floating point is infinite, then `uniformRM`/`randomR` returns that value. * Add default implementation of `uniformM` that uses `Generic` [#70](https://github.com/haskell/random/pull/70) * `Random` instance for `CBool` [#77](https://github.com/haskell/random/pull/77) * Addition of `TGen` and `TGenM` [#95](https://github.com/haskell/random/pull/95) * Addition of tuple instances for `Random` up to 7-tuple [#72](https://github.com/haskell/random/pull/72) ------------------------------------------------------------------- Thu Jul 15 16:15:27 UTC 2021 - psimons@suse.com - Update random to version 1.2.0 revision 6. Upstream has revised the Cabal build instructions on Hackage. ------------------------------------------------------------------- Sat Jul 10 14:07:02 UTC 2021 - psimons@suse.com - 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.
