# Change Log
All notable changes to this project will be documented in this file.
This project adheres to [Semantic Versioning](http://semver.org/).
## **NOT RELEASED V8**
This is going to be a very large release.
**BREAKING:**
- `Konva.Collection` is removed. `container.children` is a simple array now. `container.find()` will returns an array instead of `Konva.Collection()` instance.
`Konva.Collection` was confusing for many users. Also it was slow and worked with a bit of magic. So I decided to get rif of it. Now we are going to use good old arrays.
```js
// old code:
group.find('Shape').visible(false);
// new code:
group.find('Shape').forEach((shape) => shape.visible(false));
```
- argument `selector` is removed from `node.getIntersection(pos)` API. I don't think you knew about it.
- `Konva.Util.extend` is removed.
**New features:**
- All updates on canvas will do automatic redraw with `layer.batchDraw()`. This features is configurable with `Konva.autoDrawEnbaled` property.
- New method `layer.getNativeCanvasElement()`
- new `flipEnabled` property for `Konva.Transformer`
- new `node.isClientRectOnScreen()` method
- Added `Konva.Util.degToRad` and `Konva.Util.radToDeg`
- Added `node.getRelativePointerPosition()`
**Changes and fixes:**
- Full migration to ES modules package (!), commonjs code is removed.
- Full event system rewrite. Much better `pointer` evens support.
- `konva-node` is merged into `konva` npm package. One package works for both environments.
- Fix `TextPath` recalculations on `fontSize` change
- Better typescript support. Now every module has its own `*.d.ts` file.
- Removed `Konva.UA`, `Konva._parseUA` (it was used for old browser detection)
- Fixed Arrow head position when an arrow has tension
- `textPath.getKerning()` is removed
- Fix `a` command parsing for `Konva.Path`
- Fix fill pattern for `Konva.Text` when the pattern has an offset or rotation

## 7.1.0
- Multi row support for `ellipsis` config for `Konva.Text`
- Better `Konva.Transfomer` behavior when single attached node is programmatically rotated.
## 7.0.7

## 7.0.0 - 2020-06-23
- **BREAKING** `inherit` option is removed from `visible` and `listening`. They now just have boolean values `true` or `false`. If you do `group.listening(false);` then whole group and all its children will be removed from the hitGraph (and they will not listen to events). Probably 99% `Konva` applications will be not affected by this _breaking change_.
- **Many performance fixes and code size optimizations. Up to 70% performance boost for many moving nodes.**
- `layer.hitGraphEnabled()` is deprecated. Just use `layer.listening(false)` instead
- Better support for font families with spaces inside (like `Font Awesome 5`).
- Fix wrong `dblclick` and `dbltap` triggers
- Deprecate `Konva.FastLayer`. Use `new Konva.Layer({ listening: false });` instead.

- `dragmove` triggers only after ALL positions of dragging nodes are changed
## 6.0.0 - 2020-05-08

Otherwise you should be fine. `Konva` has major upgrade about touch events system and drag&drop flow. The API is exactly the same. But the internal refactoring is huge so I decided to make a major version. Please upgrade carefully. Report about any issues you have.

## Breaking
Customs builds are temporary removed from npm package. You can not use `import Konva from 'konva/src/Core';`.
This feature will be added back later.
### Possibly breaking
That changes are private and internal specific. They should not break most of `Konva` apps.
- `Konva.Util.addMethods` is removed
- `Konva.Util._removeLastLetter` is removed
- `Konva.Util._getImage` is removed
- `Konv.Util._getRGBAString` is removed
- `Konv.Util._merge` is removed
- Removed polyfill for `requestAnimationFrame`.

- Correct `clone()` for custom nodes
- `FastLayer` can now have transforms
- `stage.toDataURL()` method now works synchronously. So `callback` argument is not required.

### Added
- new `Konva.Image.fromURL` method
### Deprecated
- `fillRed`, `fillGreen`, `fillBlue`, `fillAlpha` are deprecated. Use `fill` instead.

- `Tween` now supports color properties (`fill`, `stroke`, `shadowColor`)
### Added
- new methods for working with node's name: `addName`, `removeName`, `hasName`.

## Rebranding release 2015-01-28
Differences from last official `KineticJS` release
- Bug Fixes
- `strokeScaleEnabled = false` is disabled for text as I can not find a way to implement this
- `strokeScaleEnabled = false` for Line now creates a correct hit graph
- working "this-example" as name for nodes
- Konva.Text() with no config will not throw exception
- Konva.Line() with no config will not throw exception
- Correct stage resizing with `FastLayer`
- `batchDraw` method for `FastLayer`
- Correct mouseover/mouseout/mouseenter/mouseleave events for groups
- cache node before adding to layer
- `intersects` function now works for shapes with shadow

- while dragging you can redraw layer that is not under drag. hit graph will be updated in this case
- now you can move object that is dragging into another layer.
- new `frameOffsets` attribute for `Konva.Sprite`
- much better dragging performance
- `browserify` support
- applying opacity to cached node
- remove all events with `node.off()`
- mouse dragging only with left button
- opacity now affects cached shapes
- Label corner radius
- smart changing `width`, `height`, `radius` attrs for circle, start, ellipse, ring.
- `mousewheel` support. Thanks [@vmichnowicz](https://github.com/vmichnowicz)
