# Derby change history

Racer provides the model and data synchronization for Derby. It's versions are updated along with Derby versions. See change history for Racer as well:
https://github.com/codeparty/racer/blob/master/History.md

## 0.3.12
The API for creating stores and sessions has changed in support of adding auth. Generating a new starter server via `derby new` is recommended

- There is no longer an app.createStore() method, and the derby.createStore() method must be used in combination with the store.modelMiddleware(). There is now a req.getModel() method added by the modelMiddleware. 
- Bugs in bracketed path interpolation in templates have been fixed, and the syntax has been updated to work more like javascript property accessors. The syntax is now `<h1>{users[_userId].name}</h1>`
- The component type is now passed as a second argument to init and create events instead of being available as a property of the component. Within the same library, the namespaces is now correctly sent as 'lib:'
- Add `log` and `path` view helper functions for debugging
- Support binding the same event to multiple space-separated function names in `x-bind`
- Set the value of component macro attributes to true when no value is specified for more easy HTML boolean style flags
- Fix a bug where using multiple apps would cause the page to reload continuously
- Default project now requires Express beta 4, since beta 6 breaks Gzippo
- Fix lots of other bugs

## 0.3.11
- Emit 'render', 'render:{ns}', 'replace', and 'replace:{ns}' events on an app when the page is rendered client-side
- Call x-bind functions with `this` set to the app or component object
- Support prototype-like definition of component methods for more efficient creation of component instances
- More careful delaying of component creation method calls instead of using setTimeout
- Fix bug in lookup of templates from an inherited namespace
- Fix bug when binding to a view helper function inside of an each and later updating array indicies
- Fix bugs in component path binding lookup
