Changes

0.1.2 [2017.06.23]

Fix the benchmark suite with criterion-1.2

0.1.1 [2017.01.22]

Expose Data.TLS.PThread.Internal. Note that there are no API guarantees whatsoever with this module, so use it with caution.
Add pthread to extra-libraries. Without it, some systems suffer from linker errors when using this library.
Fix build on GHC 7.6 and 7.8.
