## 9.3.3 / 2017-11-15

## 9.3.2 / 2017-11-14

* Don't put escaped class names into classes hash

## 9.3.1 / 2017-11-13

* Never use window object directly

## 9.3.0 / 2017-11-13

* Add CSS class name escaping for dev mode also we support emoji now! (#624)
* Added CSP over webpack (#559)

## 9.2.0 / 2017-11-06

* Allow empty rules when option {link: true} is used.
* Simplify internal logic for function values.
* Introduce function rules - similar to function values, now function can return the entire style object.

## 9.1.0 / 2017-10-31

* Added Observable rules. Now not only values can be an observable, but also the entire style object.

## 9.0.0 / 2017-09-30

* Added `SheetsManager.size` getter to get amount of items in `SheetsManager`.
* Refactored `StyleRule.selector` for better performance. Breaking change - it doesn't reregister rule in the classes map any more. It was used mainly in jss-isolate (#419).
* Method `jss.setup()` can now be called multiple times and will merge properly the options. Also it will avoid applying same plugins more than once by comparing the reference (#576).
* Fixed linker, which didn't work if selectors were escaped (#557).
* In production `createGenerateClassName()` option will now produce short selectors and warn about memory leaks. (#546)
* Update flow to v0.54.1.
* Support observable values (#442).
* Warn when dynamic properties update but link: true option is not set (#581)

## 8.1.0 / 2017-07-12

* Added webpackbin examples
* Added size-limit tool
* Added SheetsManager

## 8.0.0 / 2017-06-20

* Option `insertionPoint` can now accept a DOM node
* DOM node provided in `insertionPoint` can be inside of an iframe.
* Warn when an `insertionPoint` was specified but not found in the DOM.

### Breaking changes for users

* Option `generateClassName` which was used in Jss constructor and `Jss.setup` has been removed. A new option is called `createGenerateClassName` which is a factory that returns the old `generateClassName`. We need this to reset counters on SSR for each request.
* Removed default `insertionPoint` value ("jss") in order to have warnings when insertionPoint is not found in the DOM. With the default one we simply don't know when to warn.

### Potentially breaking changes for plugins

* KeyframeRule has been renamed to KeyframesRule.
* KeyframeRule.type === 'keyframe' => KeyFrames.type === 'keyframes'.
* RegularRule has been renamed to StyleRule
* RegularRule.type === 'regular' => StyleRule.type === 'style'.
* RegularRule.name => RegularRule.key
* ConditionalRule.selector => ConditionalRule.key
* FontFaceRule.selector => FontFaceRule.key
* SimpleRule.name => SimpleRule.key
* ViewportRule.name => ViewportRule.key
* RulesContainer => RuleList

### Breaking changes

* Option "named" has been removed from JSS core and replaced by a jss-global plugin. From now on global styles are only possible using that plugin.
* Sheets are not added to the sheets registry automatically server-side any more. In order to prevent leaking styles between requests, you now need to create your own SheetsRegistry instance and add sheets to it manually. Make sure to create a new instance for each request. On the client, sheets are still automatically added to the registry.
