lens-2.8: CHANGELOG.markdown

2.8
---
* Restored compatibility with GHC 7.2. This required a major version bump due to making some MPTC-based default signatures conditional.

2.7
---
* Generalized the signature of `Getting`, `Acting` and `IndexedGetting` to help out with the common user code scenario of needing to read
  and then write to change types.
* Documentation cleanup and additional examples.
* Renamed `au` to `ala`, introducing further incompatibility with the `newtype` package, but reducing confusion.
* Removed need for `Data.Map.Lens` and `Data.IntMap.Lens` by adding `TraverseMin` and `TraverseMax` to `Control.Lens.IndexedTraversal`.
* Flipped fixity of `~:` and `<~:`
* Added `++~`, `++=`, `<++~` and `<++=` to Data.List.Lens in response to popular demand.
* Added `|>`, `<$!>` and `<$!` to `Control.Lens.Combinators`, which exports combinators that are often useful in lens-based code, but that
  don't strictly involve lenses.
* Added an HUnit-based test suite by @orenbenkiki

2.6.1
-----
* Fixed bugs in `Traversal` code-generation.

2.6
---
* Added build option `-f-inlining` to facilitate building with the various TH 2.8 versions used by GHC 7.6 and HEAD.
* Added build option `-f-template-haskell` for testing without template haskell. (Users should be able to assume TH is enabled; use this only for testing!)
* Added support for generating a `Traversal` rather than a `Lens` when multiple fields map to the same name or some constructors are missing a field.
* Removed `_` from the lens names in `System.FilePath.Lens`.
* Added `iwhere`, `withIndices`, `withIndicesOf`, `indices` and `indicesOf` to ease work with indexed traversals
* Added `assign` as an alias for `(.=)` in `Control.Lens.Setter`.
* Added `~:`, `=:`, `<~:` and `<=:` to `Data.List.Lens`

2.5
---
* Added `Control.Lens.Plated`, a port of Neil Mitchell's `uniplate` that can be used on any `Traversal`.
* Added `Data.Data.Lens` with smart traversals that know how to avoid traversing parts of a structure that can't contain a given type.
* Added `Data.Typeable.Lens` with `_cast` and `_gcast` like `traverseData`
* Renamed `IndexedStore` to `Context` now that it is used in user-visible locations, and since I also use it as `uniplate`'s notion of a context.
* Renamed `Kleene` to `Bazaar` -- "a bazaar contains a bunch of stores."
* Added `Comonad` instances for `Context` and `Bazaar`, so we can use stores directly as the notion of an editable context in uniplate
* Compatibility with both sets of template haskell quirks for GHC 7.6.1-rc1 and the GHC 7.6.1 development head.
* Renamed `children` to `branches` in `Data.Tree.Lens`.
* Added `At` and `Contains` to `Control.Lens.IndexedLens`.
* Added `FunctorWithIndex`, `FoldableWithIndex`, and `TraversableWithIndex` under `Control.Lens.WithIndex`
* Added support for `unordered-containers`.

2.4.0.2
-------
* GHC 7.6.1 development HEAD compatibility (but broke 7.6.1-rc1)

2.4.0.1
-------
* Haddock cleanup

2.4
-----
* Added the indexed `Kleene` store to `Control.Lens.Internal`
* Moved `Gettable`, `Accessor`, `Settable` and `Mutator` to `Control.Lens.Internal`
* Added `cloneTraversal` to `Control.Lens.Traversal`
* Renamed `clone` to `cloneLens` in `Control.Lens.Type`
* Generalized the type of `zoom` to subsume `focus`.
* Removed `Focus(..)` from `Control.Lens.Type`.
* Factored out `Control.Lens.Isomorphic`.
* Moved many private types to `Control.Lens.Internal`
* Added `conFields` to `Language.Haskell.TH.Lens`.
* Added `System.FilePath.Lens`.

2.3
---
* Added missing `{-# INLINE #-}` pragmas
* Renamed `meanwhile` to `throughout` in `Control.Parallel.Strategies.Lens`
* Added `Magnify` to `Control.Lens.Getter`.
* Added `Zoom` to `Control.Lens.Type`.

2.2
---
* Added `<&=`, `<&~`, `<|=`, and `<|~`
* Moved `<>~`, `<<>~`, `<>=`, and `<<>=` to `Data.Monoid.Lens`
* Template Haskell now uses eager binding to avoid adding dependencies.

2.1
---
* Renamed `adjust` to `over`
* Added `au`, `auf` and `under`
* Added `Data.Monoid.Lens`
* Increased lower dependency bound on `mtl` for cleaner installation.
