0.4 [2021.02.17]

• heaps now always exports a null function that is specialized to Heap, i.e.,

  null :: Heap a -> Bool
  

  Previously, this specialized versions of null was only exported with GHC 7.8 or older, and for more recent GHCs, the Data.Foldable version was exported instead. The exported API is now uniform across all supported versions of GHC.

• Export adjustMin.

0.3.6.1 [2019.02.05]

• Change to build-type: Simple, and drop the doctests test suite. This was done in an effort to make heaps’ dependency footprint as minimal as possible, since heaps is used to bootstrap shake.
• Fix the Haddocks for span.

0.3.6 [2018.01.18]

• Add Semigroup instance for Heap.

0.3.5

• Support doctest-0.12

0.3.4.1

• Fix a typo in the doctests for mapMonotonic

0.3.4

• Add Bifunctor Entry instance
• Revamp Setup.hs to use cabal-doctest. This makes it build with Cabal-2.0, and makes the doctests work with cabal new-build and sandboxes.

0.3.3

• Remove redundant constraints
• Build warning-free on GHC 8.0-rc1

0.3.2.1

• Haddock fix

0.3.2

• Build without warnings on GHC 7.10
• Overload Foldable null and length on GHC 7.10+

0.3.1
