# Revision history for patch

## 0.0.8.1

* Add support for GHC 9.2 and 9.4

## 0.0.8.0 - 2022-12-09

* Drop support for GHC 8.0 and 8.2.  It may still be possible to use this library with those versions of GHC, but we do not guarantee or test it anymore.
* Fix an issue where (<>) crashed for some `PatchMapWithPatchingMove`s.
* Change `DecidablyEmpty` for `Sum` and `Product` to use `Num` and `Eq` rather than delegating to the argument type's `DecidablyEmpty` class.  Since `Sum` and `Product` have `Monoid` actions and units that are inherently based on `Num`, it makes sense to have a `DecidablyEmpty` instances that inherently agree with that.  Also, since `Int` and other numeric types don't have (and can't reasonably have) `DecidablyEmpty` instances, this is necessary to make them actually usable in this context.

## 0.0.7.0 - 2022-06-23

* Use `commutative-semigroups` for `Commutative`, making `Additive` a
  deprecated alias.

## 0.0.6.0 - 2022-06-10

* Add `PatchOrReplacement`, patch which either is some other patch type or a
  new replacement value.

* Support GHC 9.2

## 0.0.5.2 - 2022-01-09

* Correct field order of `PatchMapWithMove.NodeInfo`.

  When we this was reimplemented as a pattern synonym wrapper in 0.0.5.0, we
  accidentally flipped the argument order. Reversing it now to match 0.0.4.0
  and restore compatibility. The previous releases in the 0.0.5.\* series will
  correspondingly be deprecated.

## 0.0.5.1 - 2021-12-28

* New dep of `base-orphans` for old GHC to get instances honestly instead of
  via `monoidal-containers`.

## 0.0.5.0 - 2021-12-17

* `Additive` now lives in `Data.Semigroup.Additive`, but is still reexported
  from `Data.Patch` for compatability.

* Rewrite `PatchMapWithMove` in terms of `PatchMapWithPatchingMove`.
  Care is taken to make this not a breaking change.
  In particular, `PatchMapWithMove` is a newtype of `PatchMapWithPatchingMove`, as is the `NodeInfo` and `From` of `PatchMapWithPatchingMove`'s versions of those.
  There are complete constructor and field patterns too, and everything is
  exported under the newtype as real constructors and fields would be.

## 0.0.4.0 - 2021-04-20

* Enable PolyKinds

## 0.0.3.2 - 2020-11-06

* Update version bounds

## 0.0.3.1 - 2020-02-05

* Replace `fromJust` with something easier to debug.

## 0.0.3.0 - 2020-02-05

* Create `PatchMapWithPatchingMove` variant which supports moves with a patch.

* Create `DecidablyEmpty` subclass of `Monoid`.

## 0.0.2.0 - 2020-01-17

* Consistently provide:

   - `Wrapped` instances

   - `*WithIndex` instances

   - `un*` newtype unwrappers

  for `PatchMap`, `PatchIntMap`, and `PatchMapWithMove`.

## 0.0.1.0 - 2020-01-09

* Support older GHCs with `split-these` flag.

* Additional instances for the `Group` class for basic types.

## 0.0.0.1 - 2020-01-08

* Remove unneeded dependencies

## 0.0.0.0 - 2020-01-08

* Extract patching functionality from Reflex.
