3## 0.8.2.0
5* Add `matchResponseMapWithRequests`, which it similar to `matchResponsesWithRequests` but allows processing of multiple responses at once.

24* Fix HLint 3 test
26## 0.7.1.1
28*Backport release*.
29Changes do not carry forward to 0.7.2.0.
31* Add support for GHC 8.10
32* Drop support for GHC < 8.4
33* Extend some dependency version bounds
34* Fix HLint 3 test
36## 0.7.1.0
38* ([#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.
39* ([#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`.
40* ([#419](https://github.com/reflex-frp/reflex/pull/419)) Add `distributeIntMapOverDynPure` and `joinDynThroughIntMap` as convenience functions for working with `Dynamic` `IntMap`s.
43## 0.7.0.0
45* Add lifting instances for most classes to `Reflex.Profiled.Profiled`. ([#398](https://github.com/reflex-frp/reflex/pull/398))
46* Class `MonadQuery t q m` now has a `Monad m` superclass constraint. ([#400](https://github.com/reflex-frp/reflex/pull/400))
47* **(Breaking change)** Rename class `MonadBehaviorWriter` -> `BehaviorWriter` for consistency with `EventWriter`/`DynamicWriter`. ([#401](https://github.com/reflex-frp/reflex/pull/401))
48* Introduce deprecated alias `MonadBehaviorWriter = BehaviorWriter`. ([#401](https://github.com/reflex-frp/reflex/pull/401))
49* 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))
50* Add instances of `PerformEvent` and `TriggerEvent` for `MaybeT`. ([#395](https://github.com/reflex-frp/reflex/pull/395))
52## 0.6.4.1
54* Fix a bug in the Reflex Profiled transformer where
55 `Reflex.Class.mergeIncrementalG` and
56 `Reflex.Class.mergeIncrementalWithMoveG` implementations referenced
57 itself instead of the inner transformed timeline, causing an
58 infinite loop.
60## 0.6.4
62* Support GHC 8.8
64* Add `Reflex.Query.Base.mapQueryT`. See that module for documentation
66* The `Reflex.Patch.*` modules were moved to the `patch` library.
67 They are `Data.Patch.*` there, but reexported under their old names for backwards compatability here.
69* Additional instances for `Query` classes for basic types.
71* Add cabal flags `debug-propagation` and `debug-event-cycles` to build in debugging
72 code for performance and for cyclic dependencies between events
74## 0.6.3
76* `Data.WeakBag.traverse` and `Data.FastWeakBag.traverse` have been deprecated.
77 They are replaced with `Data.WeakBag.traverse_` and `Data.FastWeakBag.traverse_`, respectively.
79* Fixes a bug in `Reflex.Patch.MapWithMove.patchThatSortsMapWith` that was producing invalid `PatchMapWithMove`.
81* Add missing `NotReady` instances:
82 - `instance NotReady (SpiderTimeline x) (SpiderHost x)`
83 - `instance HasSpiderTimeline x => NotReady (SpiderTimeline x) (PerformEventT (SpiderTimeline x) (SpiderHost x))`
85## 0.6.2.4
87* Update to monoidal-containers 0.6
89## 0.6.2.3
91* Add an upper-bound to witherable
93## 0.6.2.2
95* Support these >= 1. Add `split-these` flag to control whether to use new these/semialign combination or not.
97* Update version bounds to fix some CI failures
99* Add travis CI configuration
101## 0.6.2.1
103* Generalize `fan` to `fanG` to take a `DMap` with non-`Identity`
104 functor:
105 * `fan` to `fanG`
106 * `EventSelectorG` for `fanG` result selector.
108* Reduce the amount of unsafeCoerce in coercing newtypes under Event/Dynamic/Behavior.
109 * Add fused ReaderIO for the purpose of coercion (ReaderT's third argument has nominal role preventing automated coerce)
110 * Add incrementalCoercion/coerceIncremental to go with dynamicCoercion/coerceDynamic
112* Generalize merging functions:
113 `merge` to `mergeG`,
114 `mergeIncremental` to `mergeIncrementalG`,
115 `mergeIncrementalWithMove` to `mergeIncrementalWithMoveG`.
117* Generalize distribute function:
118 `distributeDMapOverDynPure` to `distributeDMapOverDynPureG`,
120## 0.6.2.0
122* Fix `holdDyn` so that it is lazy in its event argument
123 These produce `DMap`s whose values needn't be `Identity`.
125* Stop using the now-deprecated `*Tag` classes (e.g., `ShowTag`).
127* Fix `holdDyn` so that it is lazy in its event argument.
129## 0.6.1.0
131* Re-export all of `Data.Map.Monoidal`
133* Fix `QueryT` and `RequesterT` tests
135## 0.6.0.0 -- 2019-03-20
137* Deprecate `FunctorMaybe` in favor of `Data.Witherable.Filterable`. We still export `fmapMaybe`, `ffilter`, etc., but they all rely on `Filterable` now.
139* Rename `MonadDynamicWriter` to `DynamicWriter` and add a deprecation for the old name.
141* Remove many deprecated functions.
143* Add a `Num` instance for `Dynamic`.
145* Add `matchRequestsWithResponses` to make it easier to use `Requester` with protocols that don't do this matching for you.
147* Add `withRequesterT` to map functions over the request and response of a `RequesterT`.
149* Suppress nil patches in `QueryT` as an optimization. The `Query` type must now have an `Eq` instance.
151* Add `throttleBatchWithLag` to `Reflex.Time`. See that module for details.
