Yup !

For those who prefer email over urls

Changes in version

   - add semigrioups dep to test suite so CI actually runs again on GHC < 8

Changes in version

   - Fix integer overflows in specializations of Bundle/Stream enumFromTo
   on Integral types
   - Fix possibility of OutOfMemory with take and very large arguments.
   - Fix slice function causing segfault and not checking the bounds
   - updated specialization rule for EnumFromTo on Float and Double to make
   sure it always matches the version in GHC Base (which changed as of 8.6)
   Thanks to Aleksey Khudyakov @Shimuuar for this fix.
   - fast rejection short circuiting in eqBy operations
   - the O2 test suite now has reasonable memory usage on every GHC
   version, special thanks to Alexey Kuleshevich (@lehins).
   - The Mutable type family is now injective on GHC 8.0 or later.
   - Using empty Storable vectors no longer results in division-by-zero
   - The Data instances for Vectortypes now have well defined
   implementations for toConstr, gunfold, and dataTypeOf.
   - New function: partitionWith.
   - Add Unbox instances for Identity, Const, Down, Dual, Sum, Product, Min
   , Max, First, Last, WrappedMonoid, Arg, Any, All, Alt, and Compose.
   - Add NFData1 instances for applicable Vector types
