0.8.1

• Add Semialign Tree, Tagged, (->) e; Align Compose and Proxy instances
• Allow semigroups-0.19 and hashable-1.3

0.8.0

• Split align and alignWith into own class: Semialign.
• ialign has default implementation
• Add Semialign NonEmpty and Identity instances
• Add Swap and Assoc instances (type classes from assoc package)
• Move optics into Data.These.Lens module, and and some combinators Data.These.Combinators. Also some combinators are renamed, so naming is now consistent. As the result Data.These has very minimal exports.
• Change type of partitionThese (nested pairs to triple)
• Add partitionHereThere :: [These a b] -> ([a],[b])

0.7.6

• Tigthen lower bounds
• Add dependency on lens
• Add assoc, reassoc, swap and Swapped instance
• Add since annotations for things added in 0.7.x
• Add AlignWithKey ZipList instance
• Add Data.Align.Indexed module.
• Add Data.Functor.These with These1 data type.
• Add associativity law
• Add toList property to enforce "align"-feel.
• Map and IntMap Align instances implemented using merge combinators (when available)

0.7.5

• Add Compose and (,) Crosswalk instances
• Add bitraverseThese

• Add These instances for
  • binary: Binary
  • aeson: FromJSON, ToJSON
  • QuickCheck: Arbitrary, CoArbitrary, Function
  • deepseq: NFData

0.7

• Breaking change: Generalized Monad, Applicative instances of These and Chronicle to require only a Semigroup constraint
• More efficient Align Seq implementation
• Add Crosswalk Seq and Vector instances
