v7.0.0-rc.9

- Fixed an issue where dependency hooks were not being reduced properly, thus the table would rerender unnecessarily
- Renamed `toggleRowSelectedAll` to `toggleAllRowsSelected`. Duh...
- Added an `indeterminate` boolean prop to the default props for row selection toggle prop getters
- Renamed `selectedRowPaths` to `selectedRowIds`, which also no longer contains paths, but row IDs
- Grouped or nested row selection actions and state are now derived, instead of tracked in state.
- Rows now have a new property called `id`, which existed before and was derived from the `getRowId` option
- Rows now also have an `isSomeSelected` prop when using the `useRowSelect` hook, which denotes that at least one subRow is selected (if applicable)
- Rows' `path` property has been deprecated in favor of `id`
- Expanded state is now tracked with row IDs instead of paths
- RowState is now tracked with row IDs instead of paths
- `toggleExpandedByPath` has been renamed to `toggleExpandedById`, and thus accepts a row ID now, instead of a row path

+
+- Fix an issue where `useResizeColumns` would crash when using the resizer prop getter
+- Fix an issue where `useBlockLayout` was clobbering props sent to headers
+
+## 7.0.0-rc.7
+
+Removed:
+
+- `applyHooks` (exported but undocumented) function has been deprecated. Please use either `reduceHooks` or `loopHooks` utilities in your custom plugins now.
+- `applyPropHooks` (exported but undocumented) function has been deprecated. Please use the `makePropGetter` utility in your custom plugins now.
+
+Added:
+
+- `reduceHooks` exported utility which is used to reduce a value through a collection of hooks. Each hook must return a value (mutation is discouraged)
+- `loopHooks` exported utility which is used to loop over a collection of hooks. Hooks are not allowed to return a value (mutation is encouraged)
+- `makePropGetter` exported utility which is used to create prop getters from a prop getter hook.
+- `useOptions` plugin hook, which allows a plugin to reduce/modify the initial options being passed to the table
+- `useFinalInstance` plugin hook, which allows a plugin access to the final table instance before it is returned to the user.
+
+Modified:
+
+- Prop-getter hook functions now support returning an array (in addition to the typical object of props). When an array is returned, each item in the array is smart-merged into a new props object (meaning it will intelligently compose and override styles and className)
+- Prop-getter function supplied to the table have 2 new overloaded options (in addition to the typical object of props):
+  - `Function(props, instance, ...row/col/context) => Array<props> | props` - If a function is passed to a prop getter function, it will receive the previous props, the table instance, and potentially more context arguments. It is then be expected to return either an array of new props (to be smart-merged with styles and classes, the latest values taking priority over the previous values) or a props object (which will replace all previous props)
+  - `Array<props>` - If an array is passed to a prop getter function, each prop object in the array will be smart-merged with styles and classes into the props from previous hooks (with the latest values taking priority over the previous values).
+- Extracted default hooks into separate file.
+- Converted almost all usages of `instanceRef.current` to use `useGetLatest(instanceRef.current)` to help with avoiding memory leaks and to be more terse.
+- Converted all previous prop-getter definitions to use the new `makePropGetter`
+- Reorganized plugin hooks to declare as many hooks in the main plugin function as opposed to in the `useInstance` hook.
+- Changed the `useInstanceBeforeDimensions` hook to be a `loopHooks` call instead of a reducer. An error will be thrown now if any of these hook functions returns a value (to encourage mutation of the instance)
+- Changed the `useInstance` hook to be a `loopHooks` call instead of a reducer. An error will be thrown now if any of these hook functions returns a value (to encourage mutation of the instance)
+- Change the `prepareRow` hook to be a `loopHooks` call instead of a reducer. An error will be thrown now if any of these hook functions returns a value (to encourage mutation of the row)
+
+## 7.0.0-rc.6
+
+- The `columnsBeforeHeaderGroups` and `columnsBeforeHeaderGroupsDeps` hooks have been renamed to `flatColumns` and `flatColumnsDeps` respectively, which better reflects what they are used for, rather than their order, which can remain implicit.
+- Added `headerGroups` and `headerGroupDeps` hooks, which, similar to `flatColumns`, allow you to decorate (and trigger) the memoized header group generation.
+- Added `columns` and `columnsDeps` hooks, which, similar to `flatColumns` and `headerGroups`, allow you to decorate (and trigger) the memoized column generation/decoration.
+- The new hook order is as follows: `columns/columnsDeps` => `flatColumns/flatColumnsDeps` => `headerGroups/headerGroupsDeps`
+- `useColumnVisibility` now uses the new `headerGroupsDeps` hook to trigger header group regeneration when visibility changes
+
+## 7.0.0-rc.5
+
+- Fixed an issue where the exported `useAsyncDebounce` method would crash if its promise throw an error.
+
+## 7.0.0-rc.4
+
+- A maintenance release, purely intended to update the @latest tag (which was overwritten by a v6 publish)
+
+## 7.0.0-rc.3
+
+- Fixed an issue where `column.clearSortBy` would crash
+
+## 7.0.0-rc.2
+
+- `reducerHandlers` has been deprecated in favor of the new `stateReducers` hook.
+  - The `previousState` and `instanceRef` are now both generally available in state reducers for convenience.
+  - The global action property `action.instanceRef` has been deprecated.
+- The `reducer` option has been renamed to `stateReducer` and in addition to passing a single reducer function now also supports passing an array of reducers
+- Renamed `manualSorting` to be `manualSortBy` to be consistent with other naming conventions
+- Removed the `getResetPageDeps` option in favor of the new `autoResetPage` option.
+- Removed the `getResetFilterDeps` option in favor of the new `autoResetFilters` option.
+- Removed the `getResetSortByDeps` option in favor of the new `autoResetSortBy` option.
+- Removed the `getResetGroupByDeps` option in favor of the new `autoResetGroupBy` option.
+- Removed the `getResetExpandedDeps` option in favor of the new `autoResetExpanded` option.
+- Added a new exported utility called `useAsyncDebounce` to aid with external async side-effects.
+- A new `useGetLatest` hook is used internally to track latest instances in a less ref-driven and verbose way.
+- A new `useMountedLayoutEffect` hooks is now used internally to handle post-mount side-effects, mostly dealing with autoReset functionality
+- Plugin hooks are now "consumed" using an internal `useConsumeHookGetter` hook. When they are consumed, they can no longer be manipulated past that point in the table lifecycle. This should help ensure people are using them in a relatively safe order with consistent expectations.
+- Drastically "reduced" the reducer logic itself to be easier to understand and to be a stable reference for the life of the table. This change also means that the reducer must no longer be double-run/back-compared by React for changes in closure, thus actions and stateReducers (including user state reducers) will only fire once per action.
+- Removed `debug` and related logging. It has been somewhat useful during development, but is now very noisy in the code. We can debug lifecycle and performance as needed from here on out.
+- Removed unnecessary exports from `./utils.js` and moved all intentionally exported utilities to a new `./publicUtils.js` file.

+  - This array of rows can be useful if building faceted filter options.
+- `filteredRows: Array<row>`
+  - The resulting array of rows received from this columns filter **after** they were filtered.

+## How can I use the table state to fetch new data?
+
+When managing your data externally or asynchronously (eg. server-side pagination/sorting/grouping/etc), you will need to fetch new data as the internal table state changes. With React Hooks, this is fantastically easier than it was before now that we have the `React.useEffect` hook. We can use this hook to "watch" the table state for specific changes and use those effects to trigger fetches for new data (or synchronize any other state you may be managing externally from your table component):
+
+```js
+function Table({ data, onFetchData }) {
+  const {
+    state: { pageIndex, pageSize, sortBy, filters },
+  } = useTable({
+    data,
+  })
+
+  // When the these table states change, fetch new data!
+  React.useEffect(() => {
+    onFetchData({ pageIndex, pageSize, sortBy, filters })
+  }, [fetchData, pageIndex, pageSize, sortBy, filters])
+
+  return </>
+}
+```
+
+Using this approach, you can respond and trigger any type of side-effect using the table instance!
+
+## How can I debounce rapid table state changes?
+
+React Table has a few built-in side-effects of it's own (most of which are meant for resetting parts of the state when `data` changes). By default, these state side-effects are on and when their conditions are met, they immediately fire off actions that will manipulate the table state. Sometimes, this may result in multiple rapid rerenders (usually just 2, or one more than normal), and could cause any side-effects you have watching the table state to also fire multiple times in-a-row. To alleviate this edge-case, React Table exports a `useAsyncDebounce` function that will allow you to debounce rapid side-effects and only use the latest one.
+
+A good example of this when doing server-side pagination and sorting, a user changes the `sortBy` for a table and the `pageIndex` is automatically reset to `0` via an internal side effect. This would normally cause our effect below to fire 2 times, but with `useAsyncDebounce` we can make sure our data fetch function only gets called once:
+
+```js
+import { useTable, useAsyncDebounce } from 'react-table'
+
+function Table({ data, onFetchData }) {
+  const {
+    state: { pageIndex, pageSize, sortBy, filters },
+  } = useTable({
+    data,
+  })
+
+  // Debounce our onFetchData call for 100ms
+  const onFetchDataDebounced = useAsyncDebounce(onFetchData, 100)
+
+  // When the these table states changes, fetch new data!
+  React.useEffect(() => {
+    // Every change will call our debounced function
+    onFetchDataDebounced({ pageIndex, pageSize, sortBy, filters })
+    // Only the last call after the 100ms debounce is over will be fired!
+  }, [onFetchDataDebounced, pageIndex, pageSize, sortBy, filters])
+
+  return </>
+}
+```
 
 ## How do I stop my table state from automatically resetting when my data changes?
 
 Most plugins use state that _should_ normally reset when the data sources changes, but sometimes you need to suppress that from happening if you are filtering your data externally, or immutably editing your data while looking at it, or simply doing anything external with your data that you don't want to trigger a piece of table state to reset automatically.
 
-For those situations, each plugin provides options like `getResetPageDeps` or `getResetExpandedDeps`, so and an so forth. These functions are provided the table `instance` and allowed to return an array of variables that will be injected into the `React.useEffect`'s dependency array that is responsible for watching and resetting those states. By returning a new array in one of these arrays, you can either stop the automatic resets from being triggered, or even trigger them more based on what you are returning. You can also return `false` for any of these options to disable the automatic resets completely, or pass `undefined` to allow the default dependendies to be used.
+For those situations, each plugin provides a way to disable the state from automatically resetting internally when data or other dependencies for a piece of state change. By setting any of them to `false`, you can stop the automatic resets from being triggered.
 
-Here is an example of completely disabling the page from resetting when data changes:
+Here is an example of stopping basically every piece of state from changing as they normally do while we edit the `data` source for a table:
 
 ```js
 const [data, setData] = React.useState([])
 const skipPageResetRef = React.useRef()
 
 const updateData = newData => {
-  // When data gets updated with this function, disable the
-  // page from resetting
+  // When data gets updated with this function, set a flag
+  // to disable all of the auto resetting
   skipPageResetRef.current = true
 
   setData(newData)
 }
 
 React.useEffect(() => {
+  // After the table has updated, always remove the flag
   skipPageResetRef.current = false
 })
 
 useTable({
-  data,
-  getResetPageDeps: skipPageReset ? false : undefined,
+  ...
+  autoResetPage: !skipPageReset,
+  autoResetExpanded: !skipPageReset,
+  autoResetGroupBy: !skipPageReset,
+  autoResetSelectedRows: !skipPageReset,
+  autoResetSortBy: !skipPageReset,
+  autoResetFilters: !skipPageReset,
+  autoResetRowState: !skipPageReset,
 })
 ```
