1.2.0.0

• Use statistics-0.14.

• Replace the hastache dependency with microstache.

• Add support for per-run allocation/cleanup of the environment with perRunEnv and perRunEnvWithCleanup,

• Add support for per-batch allocation/cleanup with perBatchEnv and perBatchEnvWithCleanup.

• Add envWithCleanup, a variant of env with cleanup support.

• Add the criterion-report executable, which creates reports from previously created JSON files.

1.1.4.0

• Unicode output is now correctly printed on Windows.

1.1.4.0

• Add Safe Haskell annotations.

• Add --json option for writing reports in JSON rather than binary format. Also: various bugfixes related to this.

• Use the js-jquery and js-flot libraries to substitute in JavaScript code into the default HTML report template.

• Use the code-page library to ensure that criterion prints out Unicode characters (like ², which criterion uses in reports) in a UTF-8-compatible code page on Windows.

• Give an explicit implementation for get in the Binary Regression instance. This should fix sporadic criterion failures with older versions of binary.

• Use tasty instead of test-framework in the test suites.

• Restore support for 32-bit Intel CPUs.

• Restore build compatibilty with GHC 7.4.

1.1.1.0

• If a benchmark uses Criterion.env in a non-lazy way, and you try to use --list to list benchmark names, you'll now get an understandable error message instead of something cryptic.

• We now flush stdout and stderr after printing messages, so that output is printed promptly even when piped (e.g. into a pager).

• A new function runMode allows custom benchmarking applications to run benchmarks with control over the Mode used.

• Added support for Linux on non-Intel CPUs.

• This version supports GHC 8.

• The --only-run option for benchmarks is renamed to --iters.

1.1.0.0

• The dependency on the either package has been dropped in favour of a dependency on transformers-compat. This greatly reduces the number of packages criterion depends on. This shouldn't affect the user-visible API.

• The documentation claimed that environments were created only when needed, but this wasn't implemented. (gh-76)

• The package now compiles with GHC 7.10.

• On Windows with a non-Unicode code page, printing results used to cause a crash. (gh-55)

1.0.2.0

• Bump lower bound on optparse-applicative to 0.11 to handle yet more annoying API churn.

1.0.1.0

• Added a lower bound of 0.10 on the optparse-applicative dependency, as there were major API changes between 0.9 and 0.10.
