### Patches

- Fixed `ModelsTreeComponent` and `CategoriesTreeComponent` logging error due to setState calls during render. ([#1519](https://github.com/iTwin/viewer-components-react/pull/1519))

## 3.17.2

Tue, 18 Nov 2025 15:20:07 GMT

### Patches

- Models tree: Fixed an issue where models/subjects with child-only categories would have partial visibility (instead of hidden) when elements from other models were added to the exclusive always drawn list. ([#1514](https://github.com/iTwin/viewer-components-react/pull/1514))

## 3.17.1

Thu, 13 Nov 2025 09:36:43 GMT

### Patches

- Models and Categories trees: reduce main thread blockage for large iModels when determining visibility. ([#1499](https://github.com/iTwin/viewer-components-react/pull/1499))
- Models tree: Fixed parent / child elements visibility controls. Now, changing element visibility also changes visibility of all nested children. Also, determining element visibility takes into account all child elements that are in the always/never drawn sets. ([#1477](https://github.com/iTwin/viewer-components-react/pull/1477))

## 3.17.0

Mon, 03 Nov 2025 07:50:14 GMT

### Minor changes

- Categories tree: Add option to show categories that don't contain any elements. This option can be provided to `CategoriesTree`, `CategoriesTreeComponent` or `useCategoriesTree`. It can be provided as `hierarchyConfig` property called `showEmptyCategories` ([#1486](https://github.com/iTwin/viewer-components-react/pull/1486))

### Patches

- Fix category elements count query being cancelled due to restart token. ([#1484](https://github.com/iTwin/viewer-components-react/pull/1484))

## 3.16.0

Fri, 17 Oct 2025 15:36:01 GMT

### Minor changes

- Tree widget: fix issue with queries being cancelled due to the same restart token. Fixed by adding a unique guid to each restart token. Changed `showAllModels` to now accept optional componentId, which is used in the restart tokens. ([#1478](https://github.com/iTwin/viewer-components-react/pull/1478))

### Patches

- Bump versions of presentation packages ([#1480](https://github.com/iTwin/viewer-components-react/pull/1480))

## 3.15.1

Tue, 07 Oct 2025 08:45:29 GMT

### Patches

- Models tree: Fixed visibility change incorrectly setting visibility when `alwaysDrawn` exclusive flag is set to `true`. Now, before making any visibility changes to the desired node, `alwaysDrawn` exclusive flag is reset to `false`, all categories are turned off, never drawn list is cleared and all per-model category overrides are removed. ([#1467](https://github.com/iTwin/viewer-components-react/pull/1467))

## 3.15.0

Fri, 03 Oct 2025 11:22:06 GMT

### Minor changes

- Introduce an extra state to `TreeNodeCheckboxState` interface - `{ isLoading: true }`. When such state is returned, the "eye" checkboxes are not rendered by `<VisibilityTreeRenderer />` and `<TreeNodeRenderer />`. Previously, we were returning "disabled" state, resulting in disabled checkboxes being briefly shown until the states were loaded. ([#1458](https://github.com/iTwin/viewer-components-react/pull/1458))

### Patches

- Models tree: reduce tree visibility icon flickering when changing visibility. ([#1462](https://github.com/iTwin/viewer-components-react/pull/1462))
- Models tree: Fixed adding elements to always/never drawn lists would cause model to not load its' visibility. ([#1461](https://github.com/iTwin/viewer-components-react/pull/1461))

## 3.14.2

Tue, 16 Sep 2025 11:13:44 GMT

### Patches

- Models tree: Fixed turning on category visibility under a hidden model causing categories of child elements to also become visible. ([#1452](https://github.com/iTwin/viewer-components-react/pull/1452))
- Fix a query being unnecessarily executed after every node visibility change. ([#1439](https://github.com/iTwin/viewer-components-react/pull/1439))

## 3.14.1

Thu, 28 Aug 2025 19:47:46 GMT

### Patches

- Adjust models and categories trees in tree widget. They no longer re-query information after users clear active hierarchy filter. ([#1431](https://github.com/iTwin/viewer-components-react/pull/1431))

## 3.14.0

Thu, 21 Aug 2025 11:00:38 GMT

### Minor changes

- Allow Model tree's `getFilteredPaths` prop function to return `undefined` paths. In that case, it's considered that filtering should not be applied, and the full unfiltered tree should be loaded. ([#1417](https://github.com/iTwin/viewer-components-react/pull/1417))

## 3.13.2

Thu, 07 Aug 2025 18:43:06 GMT

### Patches

- Models tree: Stop unnecessarily executing an expensive model elements' count query, whose results we weren't even using.

## 3.13.1

Thu, 07 Aug 2025 12:12:57 GMT

### Patches

- Split large queries into smaller chunks to make them execute quicker. ([#1396](https://github.com/iTwin/viewer-components-react/pull/1396))

## 3.13.0

Wed, 06 Aug 2025 13:46:52 GMT

### Minor changes

- Added `getActions` callback to `TreeRenderer` components. It allows to supply custom actions for tree nodes. ([#1395](https://github.com/iTwin/viewer-components-react/pull/1395))

## 3.12.1

Wed, 06 Aug 2025 10:14:27 GMT

### Patches

- Models tree: Fixed not all required nodes being auto-expanded when using `getSubTreePaths` together with filtering. ([#1391](https://github.com/iTwin/viewer-components-react/pull/1391))

## 3.12.0

Wed, 30 Jul 2025 13:10:01 GMT

### Minor changes

- Added `getSubTreePaths` option to `UseModelsTreeProps` for restricting the visible hierarchy to a sub-tree of nodes based on instance keys. Unlike `getFilteredPaths`, which controls filtering logic, `getSubTreePaths` limits the scope of the hierarchy, allowing filtering within the specified sub-tree. ([#1375](https://github.com/iTwin/viewer-components-react/pull/1375))

## 3.11.0

Thu, 24 Jul 2025 16:07:32 GMT

### Minor changes

- Updated @itwin/presentation-hierarchies to v1.6.1 and @itwin/presentation-hierarchies-react to 1.7.1 ([#1379](https://github.com/iTwin/viewer-components-react/pull/1379))

### Patches

- Fix categories tree incorectly inverting categories visibility. ([#1381](https://github.com/iTwin/viewer-components-react/pull/1381))

## 3.10.3

Mon, 14 Jul 2025 12:38:56 GMT

### Patches

- Added missing peer dependencies. ([#1376](https://github.com/iTwin/viewer-components-react/pull/1376))

## 3.10.2

Mon, 07 Jul 2025 19:55:02 GMT

### Patches

- Bumped `@itwin/presentation-hierarchies-react` version. ([#1368](https://github.com/iTwin/viewer-components-react/pull/1368))
- Fix category count query throwing error on large iModels ([#1364](https://github.com/iTwin/viewer-components-react/pull/1364))

## 3.10.1

Fri, 20 Jun 2025 17:05:06 GMT

### Patches

- Update itwinjs-core dependencies to v5.0.0 ([#1349](https://github.com/iTwin/viewer-components-react/pull/1349))

## 3.10.0

Mon, 02 Jun 2025 13:19:21 GMT

### Minor changes

- `useModelsTree`: The `getFilteredPaths` callback prop now has a `filter` prop, which matches the value of `filter` prop passed to `useModelsTree` hook. This make it more convenient for consumers to filter by instance keys and label at the same time. ([#1335](https://github.com/iTwin/viewer-components-react/pull/1335))

## 3.9.0

Mon, 19 May 2025 16:58:21 GMT

## 3.8.0

Thu, 15 May 2025 05:33:32 GMT

### Minor changes

- Fixed merged (categories and models) nodes visibility. Changed `@beta` APIs in a **breaking** way: `ModelsTreeVisibilityHandlerOverrides.getModelDisplayStatus` and `ModelsTreeVisibilityHandlerOverrides.getCategoryDisplayStatus` - `id` and `categoryId` props are now of `Id64Arg` type instead of `Id64String`. Use `Id64` from `@itwin/core-bentley` to access individual IDs. ([#1311](https://github.com/iTwin/viewer-components-react/pull/1311))

### Patches

- update presentation deps to versions that properly support core @ 5.0-rc ([#1304](https://github.com/iTwin/viewer-components-react/pull/1304))

## 3.7.0

Mon, 28 Apr 2025 16:18:43 GMT

### Minor changes

- Added ability to disabled hierarchy level filtering in `ModelsTree`. ([#1297](https://github.com/iTwin/viewer-components-react/pull/1297))

## 3.6.1

Fri, 18 Apr 2025 17:06:22 GMT

### Patches

- Fixed Categories tree not reacting to Category display changes from Models tree, when they're made on per-model category overrides. ([#1284](https://github.com/iTwin/viewer-components-react/pull/1284))
- Fixed `ModelsTree` and `CategoriesTree` not applying custom hierarchy level size limit. ([#1292](https://github.com/iTwin/viewer-components-react/pull/1292))

## 3.6.0

Fri, 21 Mar 2025 11:37:20 GMT

### Minor changes

- Add ability to remove root Subject node from Models and iModel content trees by setting `hideRootSubject: true` in the `hierarchyConfig` prop. ([#1251](https://github.com/iTwin/viewer-components-react/pull/1251))

### Patches

- Fixed Models tree showing that modeled elements have children, when their sub model is private or when sub model does not have any elements. Now it shows that modeled element has children only when it's sub model has children and is not private. ([#1253](https://github.com/iTwin/viewer-components-react/pull/1253))
- Fixed Categories tree showing definition containers that contain categories without elements. Now it displays definition containers only when they have categories that contain elements. ([#1248](https://github.com/iTwin/viewer-components-react/pull/1248))

## 3.5.1

Thu, 06 Mar 2025 12:37:44 GMT

### Patches

- Update import to use `@itwin/core-bentley` for types that are reexported by `@itwin/core-common` ([#1232](https://github.com/iTwin/viewer-components-react/pull/1232))

## 3.5.0

Wed, 19 Feb 2025 21:08:10 GMT

### Minor changes

- `CategoriesTree` component rendered `Categories` as a flat list, where each `Category` had zero or more child `SubCategories`. Some iTwin.js applications started to group `Categories` under `DefinitionContainers` and wanted to see them displayed in `CategoriesTree` component. Added `DefinitionContainers` to `CategoriesTree` component. This change doesn't affect applications that don't have `DefinitionContainers`. ([#1172](https://github.com/iTwin/viewer-components-react/pull/1172))

## 3.4.2

Fri, 14 Feb 2025 15:54:49 GMT

### Patches

- Adjusted modeled element / sub-model visibility controls. Now, if visibility of modeled element is changed, visibility of sub-model is adjusted accordingly and vice versa. ([#1183](https://github.com/iTwin/viewer-components-react/pull/1183))

## 3.4.1

Thu, 06 Feb 2025 13:36:20 GMT

### Patches

- Removed horizontal scroll from trees. ([#1180](https://github.com/iTwin/viewer-components-react/pull/1180))

## 3.4.0

Tue, 04 Feb 2025 15:29:52 GMT

### Minor changes

- Expose `FocusedInstancesContextProvider` and `useFocusedInstancesContext` to allow using `ModelsTreeComponent.ToggleInstancesFocusButton` from outside of `ModelsTreeComponent` and accesing the context from other React components. ([#1175](https://github.com/iTwin/viewer-components-react/pull/1175))
- Add `filterButtonsVisibility` prop to `TreeRenderer`. The prop allows to control visibility of hierarchy level filtering buttons in the tree: `show-on-hover` (default) shows them on hover or focus, `hide` only shows them when a node is filtered. ([#1178](https://github.com/iTwin/viewer-components-react/pull/1178))

## 3.3.0

Mon, 27 Jan 2025 18:30:40 GMT

### Minor changes

- Define `type` and `exports` attributes in `package.json`. The `exports attribute prohibits access to APIs that are not intended to be used by external consumers. The `type: "module"` attribute addition moves this package a step closer towards dropping CommonJS support - it's now transpiled from ESM to CommonJS instead of the opposite. ([#1147](https://github.com/iTwin/viewer-components-react/pull/1147))
- Add support for AppUI 5.x ([#1147](https://github.com/iTwin/viewer-components-react/pull/1147))

### Patches

- Fix visibility button with no content rendering empty tooltip. ([#1145](https://github.com/iTwin/viewer-components-react/pull/1145))

## 3.2.4

Tue, 14 Jan 2025 02:51:04 GMT

### Patches

- Fixed a bug in `CategoriesTreeDefinition.createInstanceKeyPaths`, where sometimes incorrect key paths would be created. Because of this, `CategoriesTree` would show incorrect categories with applied label filter. ([#1139](https://github.com/iTwin/viewer-components-react/pull/1139))

## 3.2.3

Wed, 08 Jan 2025 13:28:10 GMT

### Patches

- Changed `onHierarchyLoad` to log errors to console ([#1135](https://github.com/iTwin/viewer-components-react/pull/1135))

## 3.2.2

Tue, 07 Jan 2025 16:30:55 GMT

### Patches

- Propagate `enableVirtualization` flag down to the underlying `Tree` component from `iTwinUI` ([#1133](https://github.com/iTwin/viewer-components-react/pull/1133))

## 3.2.1

Tue, 07 Jan 2025 12:53:32 GMT

### Patches

- Increase performance consistency when creating filtering paths from target items. ([#1130](https://github.com/iTwin/viewer-components-react/pull/1130))
- Reduced main thread blockage ~3 times when creating filtering paths from target items. ([#1123](https://github.com/iTwin/viewer-components-react/pull/1123))

## 3.2.0

Wed, 18 Dec 2024 12:42:56 GMT

### Minor changes

- Added an optional `selectionPredicate` function prop to `ModelsTreeComponent`, `ModelsTree`, `useModelsTree` and `Tree` components. When provided, it allows consumers to conditionally enable/disable selection of tree nodes. ([#1124](https://github.com/iTwin/viewer-components-react/pull/1124))

### Patches

- Bump dependencies ([#1122](https://github.com/iTwin/viewer-components-react/pull/1122))

## 3.1.0

Fri, 29 Nov 2024 10:43:06 GMT

### Minor changes

- Replaced `ModelsTreeVisibilityHandlerOverrides.changeElementState` with `ModelsTreeVisibilityHandlerOverrides.changeElementsState`. The method is provided with a list of elements instead of single element to allow changing visibility of multiple elements in single batch istead of one by one. ([#1098](https://github.com/iTwin/viewer-components-react/pull/1098))

### Patches

- Bump dependencies ([#1103](https://github.com/iTwin/viewer-components-react/pull/1103))
- Add missing tooltips ([#1092](https://github.com/iTwin/viewer-components-react/pull/1092))
- Reduce the number of queries being executed when always/never drawn sets change. ([#1102](https://github.com/iTwin/viewer-components-react/pull/1102))
- Improve performance of visibility status calculation and visibility changes. Also reduce main thread blocking to avoid UI freezing. ([#1098](https://github.com/iTwin/viewer-components-react/pull/1098))

## 3.0.3

Fri, 15 Nov 2024 15:03:19 GMT

### Patches

- Reduce UI blocking when checking visibility status ([#1094](https://github.com/iTwin/viewer-components-react/pull/1094))

## 3.0.2

Tue, 12 Nov 2024 12:57:13 GMT

### Patches

- Update ECSQL queries to always use `.Id` suffix when querying navigation properties - that substantially improves query performance. ([#1085](https://github.com/iTwin/viewer-components-react/pull/1085))
- Models tree: Improved performance of creating instance key paths for large numbers of target instances by up to 200x. ([#1084](https://github.com/iTwin/viewer-components-react/pull/1084))
- Updated `TreeNodeRenderer` to pass `ref` to the underlying `TreeNodeRenderer` from `@itwin/presentation-hierarchies-react`. ([#1078](https://github.com/iTwin/viewer-components-react/pull/1078))

## 3.0.1

Tue, 15 Oct 2024 20:19:11 GMT

### Patches

- Bump `presentation` package dependencies for bug fixes and orders of magnitude hierarchy filtering performance improvement. ([#1067](https://github.com/iTwin/viewer-components-react/pull/1067))

## 3.0.0

Fri, 04 Oct 2024 15:06:44 GMT

### Major changes

- The `3.0` release affects nearly all components in this package, usually in a breaking way. As a result, we suggest treating this version as a completely new package rather than an incremental upgrade - please have a look at the [README](./README.md) for a list of new features and examples on how to consume the new version ([#966](https://github.com/iTwin/viewer-components-react/pull/966))

## 2.3.2

- Widget: Reworked the way trees are provided to the widget. Instead of having separate configuration properties for hiding default trees and adding additional trees now there is only one property for supplying a list of trees to show.
- Refactored `IModelContentTreeProps` to not inherit `HTMLDivElement` props.
- `IVisibilityHandler`: Methods `getVisibilityStatus` and `changeVisibility` don't take `NodeKey` argument anymore.
- Models tree: `ModelsTreeProps.enableElementsClassGrouping` has been moved to `ModelsTreeProps.hierarchyConfig.enableElementsClassGrouping`.

### Minor changes

- Models tree: Removed expansion toggle for root node.
- Widget: Added ability to conditionally show trees.
- Trees: Decrease whitespace size between the node label and eye checkbox.
- Added base tree props interface for props shared between trees.
- External sources tree: Add `ExternalSourcesTreeComponent` (currently `@alpha`).
- Models tree: Added an option to specialize the class of geometric elements loaded into the hierarchy (see `ModelsTreeHierarchyConfiguration.elementClassSpecification`).
- Trees: Use search box from the `@itwin/itwinui-react` library.

### Patches

- Trees: Keep child nodes state the same after parent node re-expands.
- Categories tree: Fixed behavior of the Invert button. Previously, only categories were affected, now sub-categories are affected as well.
- Handle errors thrown from tree components.
- Persist tree scroll position when switching between widgets.
- `Tree Header`: Fixed dropdown buttons menu not theming correctly.
- `ModelsTree`: Refactor ruleset to not use deprecated `ImageIdOverride` rule.
