10* Drop support for GHC < 8.4
12## 0.8.0.0

19* Extend some dependency version bounds
20* Fix HLint 3 test
22## 0.7.1.1
24*Backport release*.
25Changes do not carry forward to 0.7.2.0.
27* Add support for GHC 8.10
28* Drop support for GHC < 8.4
29* Extend some dependency version bounds
30* Fix HLint 3 test
32## 0.7.1.0
34* ([#413](https://github.com/reflex-frp/reflex/pull/413), [#417](https://github.com/reflex-frp/reflex/pull/417)) Add `Reflex.Host.Headless` module which provides `runHeadlessApp` as an easy way to run a Reflex network in a "headless" environment.
35* ([#420](https://github.com/reflex-frp/reflex/pull/420)) Add a [`Data.Zip.Unzip`](https://hackage.haskell.org/package/semialign-1.1/docs/Data-Zip.html#t:Unzip) instance for `Event`.
36* ([#419](https://github.com/reflex-frp/reflex/pull/419)) Add `distributeIntMapOverDynPure` and `joinDynThroughIntMap` as convenience functions for working with `Dynamic` `IntMap`s.
39## 0.7.0.0
41* Add lifting instances for most classes to `Reflex.Profiled.Profiled`. ([#398](https://github.com/reflex-frp/reflex/pull/398))
42* Class `MonadQuery t q m` now has a `Monad m` superclass constraint. ([#400](https://github.com/reflex-frp/reflex/pull/400))
43* **(Breaking change)** Rename class `MonadBehaviorWriter` -> `BehaviorWriter` for consistency with `EventWriter`/`DynamicWriter`. ([#401](https://github.com/reflex-frp/reflex/pull/401))
44* Introduce deprecated alias `MonadBehaviorWriter = BehaviorWriter`. ([#401](https://github.com/reflex-frp/reflex/pull/401))
45* Fix bug in spider where event subscriptions would be prematurely finalized due to over-aggressive inlining. ([#409](https://github.com/reflex-frp/reflex/pull/409))
46* Add instances of `PerformEvent` and `TriggerEvent` for `MaybeT`. ([#395](https://github.com/reflex-frp/reflex/pull/395))
48## 0.6.4.1
50* Fix a bug in the Reflex Profiled transformer where
51 `Reflex.Class.mergeIncrementalG` and
52 `Reflex.Class.mergeIncrementalWithMoveG` implementations referenced
53 itself instead of the inner transformed timeline, causing an
54 infinite loop.
56## 0.6.4
58* Support GHC 8.8
60* Add `Reflex.Query.Base.mapQueryT`. See that module for documentation
62* The `Reflex.Patch.*` modules were moved to the `patch` library.
63 They are `Data.Patch.*` there, but reexported under their old names for backwards compatability here.
65* Additional instances for `Query` classes for basic types.
67* Add cabal flags `debug-propagation` and `debug-event-cycles` to build in debugging
68 code for performance and for cyclic dependencies between events
70## 0.6.3
72* `Data.WeakBag.traverse` and `Data.FastWeakBag.traverse` have been deprecated.
73 They are replaced with `Data.WeakBag.traverse_` and `Data.FastWeakBag.traverse_`, respectively.
75* Fixes a bug in `Reflex.Patch.MapWithMove.patchThatSortsMapWith` that was producing invalid `PatchMapWithMove`.
77* Add missing `NotReady` instances:
78 - `instance NotReady (SpiderTimeline x) (SpiderHost x)`
79 - `instance HasSpiderTimeline x => NotReady (SpiderTimeline x) (PerformEventT (SpiderTimeline x) (SpiderHost x))`
81## 0.6.2.4
83* Update to monoidal-containers 0.6
85## 0.6.2.3
87* Add an upper-bound to witherable
89## 0.6.2.2
91* Support these >= 1. Add `split-these` flag to control whether to use new these/semialign combination or not.
93* Update version bounds to fix some CI failures
95* Add travis CI configuration
97## 0.6.2.1
99* Generalize `fan` to `fanG` to take a `DMap` with non-`Identity`
100 functor:
101 * `fan` to `fanG`
102 * `EventSelectorG` for `fanG` result selector.
104* Reduce the amount of unsafeCoerce in coercing newtypes under Event/Dynamic/Behavior.
105 * Add fused ReaderIO for the purpose of coercion (ReaderT's third argument has nominal role preventing automated coerce)
106 * Add incrementalCoercion/coerceIncremental to go with dynamicCoercion/coerceDynamic
108* Generalize merging functions:
109 `merge` to `mergeG`,
110 `mergeIncremental` to `mergeIncrementalG`,
111 `mergeIncrementalWithMove` to `mergeIncrementalWithMoveG`.
113* Generalize distribute function:
114 `distributeDMapOverDynPure` to `distributeDMapOverDynPureG`,
116## 0.6.2.0
118* Fix `holdDyn` so that it is lazy in its event argument
119 These produce `DMap`s whose values needn't be `Identity`.
121* Stop using the now-deprecated `*Tag` classes (e.g., `ShowTag`).
123* Fix `holdDyn` so that it is lazy in its event argument.
125## 0.6.1.0
127* Re-export all of `Data.Map.Monoidal`
129* Fix `QueryT` and `RequesterT` tests
131## 0.6.0.0 -- 2019-03-20
133* Deprecate `FunctorMaybe` in favor of `Data.Witherable.Filterable`. We still export `fmapMaybe`, `ffilter`, etc., but they all rely on `Filterable` now.
135* Rename `MonadDynamicWriter` to `DynamicWriter` and add a deprecation for the old name.
137* Remove many deprecated functions.
139* Add a `Num` instance for `Dynamic`.
141* Add `matchRequestsWithResponses` to make it easier to use `Requester` with protocols that don't do this matching for you.
143* Add `withRequesterT` to map functions over the request and response of a `RequesterT`.
145* Suppress nil patches in `QueryT` as an optimization. The `Query` type must now have an `Eq` instance.
147* Add `throttleBatchWithLag` to `Reflex.Time`. See that module for details.
