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.
