0.15.0

BREAKING CHANGES

• The unique key generated values have changed. Previously, Slate generated unique keys that looked like '9dk3'. But they were not very conflict-resistant. Now the keys are simple string of auto-incrementing numbers, like '0', '1', '2'. This makes more clear that keys are simply a convenient way to uniquely reference nodes in the short-term lifespan of a single in-memory instance of Slate. They are not designed to be used for long-term uniqueness. A new setKeyGenerator function has been exported that allows you to pass in your own key generating mechanism if you want to ensure uniqueness.
• The Raw serializer doesn't preserve keys by default. Previously, the Raw serializer would omit keys when passed the terse: true option, but preserve them without it. Now it will always omit keys, unless you pass the new preserveKeys: true option. This better reflects that keys are temporary, in-memory IDs.
• Operations on the document now update the selection when needed. This won't affect you unless you were doing some very specific things with transforms and updating selections. Overall, this makes it much easier to write transforms, since in most cases, the underlying operations will update the selection as you would expect without you doing anything.

DEPRECATION CHANGES

• Node accessor methods no longer accept being passed another node! Previously, node accessor methods like node.getParent could be passed either a key string or a node object. For performance reasons, passing in a node object is being deprecated. So if you have any calls that look like: node.getParent(descendant), they will now need to be written as node.getParent(descendant.key). They will throw a warning for now, and will throw an error in a later version of Slate.

0.14.0

BREAKING CHANGES

• The undo and redo transforms need to be applied! Previously, undo and redo were special cased such that they did not require an .apply() call, and instead would return a new State directly. Now this is no longer the case, and they are just like every other transform.
• Transforms are no longer exposed on State or Node. The transforms API has been completely refactored to be built up of "operations" for collaborative editing support. As part of this refactor, the transforms are now only available via the state.transform() API, and aren't exposed on the State or Node objects as they were before.
• Transform objects are now mutable. Previously Transform was an Immutable.js Record, but now it is a simple constructor. This is because transforms are inherently mutating their representation of a state, but this decision is up for discussion.
• The selection can now be "unset". Previously, a selection could never be in an "unset" state where the anchorKey or focusKey was null. This is no longer technically true, although this shouldn't really affect anyone in practice.

0.13.0

BREAKING CHANGES

• The renderNode and renderMark properties are gone! Previously, rendering nodes and marks happened via these two properties of the <Editor>, but this has been replaced by the new schema property. Check out the updated examples to see how to define a schema! There's a good chance this eliminates extra code for most use cases! 😄
• The renderDecorations property is gone! Decoration rendering has also been replaced by the new schema property of the <Editor>.

0.12.0

BREAKING CHANGES

• The data.files property is now an Array. Previously it was a native FileList object, but needed to be changed to add full support for pasting an dropping files in all browsers. This shouldn't affect you unless you were specifically depending on it being array-like instead of a true Array.

0.11.0

BREAKING CHANGES

• Void nodes are renderered implicitly again! Previously Slate had required that you wrap void node renderers yourself with the exposed <Void> wrapping component. This was to allow for selection styling, but a change was made to make selection styling able to handled in Javascript. Now the <Void> wrapper will be implicitly rendered by Slate, so you do not need to worry about it, and "voidness" only needs to toggled in one place, the isVoid: true property of a node.

0.10.0

BREAKING CHANGES

• Marks are now renderable as components. Previously the only supported way to render marks was by returning a style object. Now you can return a style object, a class name string, or a full React component. Because of this, the DOM will be renderered slightly differently than before, resulting in an extra <span> when rendering non-component marks. This won't affect you unless you were depending on the DOM output by Slate for some reason.

0.9.0

BREAKING CHANGES

• The wrap and unwrap method signatures have changed! Previously, you would pass type and data as separate parameters, for example: wrapBlock('code', { src: true }). This was inconsistent with other transforms, and has been updated such that a single argument of properties is passed instead. So that example could now be: wrapBlock({ type: 'code', { data: { src: true }}). You can still pass a type string as shorthand, which will be the most frequent use case, for example: wrapBlock('code').

0.8.0

BREAKING CHANGES

• The onKeyDown and onBeforeInput handlers signatures have changed! Previously, some Slate handlers had a signature of (e, state, editor) and others had a signature of (e, data, state, editor). Now all handlers will be passed a data object—which contains Slate-specific data related to the event—even if it is empty. This is helpful for future compatibility where we might need to add data to a handler that previously didn't have any, and is nicer for consistency. The onKeyDown handler's new data object contains the key name, code and a series of is* properties to make working with hotkeys easier. The onBeforeInput handler's new data object is empty.
• The Utils export has been removed. Previously, a Key utility and the findDOMNode utility were exposed under the Utils object. The Key has been removed in favor of the data object passed to onKeyDown. And then findDOMNode utility has been upgraded to a top-level named export, so you'll now need to access it via import { findDOMNode } from 'slate'.
• Void nodes now permanently have " " as content. Previously, they contained an empty string, but this isn't technically correct, since they have content and shouldn't be considered "empty". Now they will have a single space of content. This shouldn't really affect anyone, unless you happened to be accessing that string for serialization.
• Empty inline nodes are now impossible. This is to stay consistent with native contenteditable behavior, where although technically the elements can exist, they have odd behavior and can never be selected.

0.7.0

BREAKING CHANGES

• The Raw serializer is no longer terse by default! Previously, the Raw serializer would return a "terse" representation of the document, omitting information that wasn't strictly necessary to deserialize later, like the key of nodes. By default this no longer happens. You have to opt-in to the behavior by passing { terse: true } as the second options argument of the deserialize and serialize methods.

0.6.0

BREAKING CHANGES

• Void components are no longer rendered implicity! Previously, Slate would automatically wrap any node with isVoid: true in a <Void> component. But doing this prevented you from customizing the wrapper, like adding a className or style property. So you must now render the wrapper yourself, and it has been exported as Slate.Void. This, combined with a small change to the <Void> component's structure allows the "selected" state of void nodes to be rendered purely with CSS based on the :focus property of a <Void> element, which previously had to be handled in Javascript. This allows us to streamline selection-handling logic, improving performance and reducing complexity.
• data-offset-key is now <key>-<index> instead of <key>:<start>-<end>. This shouldn't actually affect anyone, unless you were specifically relying on that attribute in the DOM. This change greatly reduces the number of re-renders needed, since previously any additional characters would cause a cascading change in the <start> and <end> offsets of latter text ranges.
