and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).

## Unreleased

### Added
- Added a new `buildOrPatch` function to the `SystemApi` to allow reusing the passed obsoleted dom element.

### Improved
- The `Replacing` and `Reflecting` behaviours will now attempt to reuse existing DOM elements when replacing components. The `reuseDom` config can be used to disable this behaviour for specific components.
- The `GuiSetup` test helper will now keep the elements in the DOM on test failures.

### Changed
- Upgraded to Katamari 9.0, which includes breaking changes to the `Optional` API used in this module.
- Firefox will now use the native `focusin` and `focusout` events instead of capturing the `focus` and `blur` events.
- Horizontal and Vertical slider data is now just a number, instead of objects with single `x` or `y` properties #TINY-8304

### Fixed
- Slider components did not respond to `Representing.setValue` #TINY-8304

### Removed
- Removed support for Microsoft Internet Explorer and legacy Microsoft Edge.

## 9.0.2 - 2021-10-11

### Fixed
- Fixed sketcher behaviours augmenting in the wrong order, which prevented behaviours being revoked.
- Fixed debugging throwing errors.
- `Docking` state could end up incorrect internally, which caused `Docking.refresh()` to not work.

## 9.0.0 - 2021-08-26

### Added
- Added new `focus` property to the `Blocking` behaviour config.
- Added a new `preserve` option to `LayoutInset` which will preserve the previous placement inside the component.
- Added a new `flip` option to `LayoutInset` which will swap the previous placement to the opposite direction inside the component.
- Added the `alwaysFit` layout property which allows for the layout to specify if it should always claim to fit, no matter what.
- `Bubble` can include an optional `inset` class to be added when using an inset layout.
- The `Positioning` behaviour now supports transitioning when changing the position of a component.
- Added a new `reset` API to the `Positioning` behaviour to reset the component back to it's original position.
- The `transitioncancel` event can now be listened to by the alloy event system.

### Improved
- Improved the performance of constructing event handlers and components.
- Improved the performance of split toolbars when there were no groups to render.

### Changed
- All components now expose their `uid`.
- Changed disconnected components to log a warning instead of throwing an error when triggering or broadcasting events.
- Renamed `LayoutInside` to `LayoutInset` to better reflect what it does.
- Changed `LayoutInset` rendering behaviour, as it was inconsistent with other layouts. It will now mirror the `Layout` logic for each direction.
- Renamed the `anchor` property in anchor specs to `type`.
- Changed the `Positioning` behaviour APIs to require a `PlacementSpec` instead of an `AnchorSpec`.
- Changed the `Positioning` behaviour to store the last placement state of each placee component. This is used for determining how a component should transition.
- Upgraded to Katamari 8.0, which includes breaking changes to the `Optional` API used in this module.

### Fixed
- Fixed a number of positioning bugs when using an "inset" layout, especially any that renders at the bottom.
- `LayoutInset` bubble classes were applied incorrectly, causing the bubble arrows to show on the opposite side.
- `MakeshiftAnchorSpec` did not extend `HasLayoutAnchorSpec` which meant layouts couldn't be used for makeshift anchors.
- `TieredMenu` child menus were incorrectly opened when the parent menu item was disabled.
- Fixed selection box creation in `SelectionAnchor` to avoid context menu covering text when multiple lines are selected.

## 8.2.0 - 2021-05-06

### Added
- Added a new `setValue` method to the `SliderUi`. This allows the slider value to be modified without firing a change event.

- Exposed the `AriaVoice` voice module in the API.

### Changed
- The `AriaOwner` module, `Boxes` module, `Pinching` behaviour and `SnapConfig`/`SnapOutput` specs no longer use thunked functions and instead use the variable directly.
- All uses of `Struct.immutableBag` and `Struct.immutable` have been replaced with readonly interfaces.
