#Release Notes#

##SmartStore.NET 2.1#

###New Features###
* (Developer) *Overhauled plugin architecture*:
	- Plugins are regular MVC areas now
	- No embedded views anymore. Views get copied to the deployment folder
	- No cumbersome return View("Very.Long.View.Identifier") anymore
	- Views in plugin source folders can be edited during debug. The changes are reflected without plugin recompilation.
* (Developer) *Theme inheritance*: create derived child themes with minimum effort by overriding only small parts (static files and even variables).
* *Preview Mode*: virtually test themes and stores more easily
* New payment plugin *Pay with Amazon*
* Support for *hierarchical SEO slugs*, e.g.: samsung/galaxy/s5/16gb/white
* (Developer) Model binding for plugin tab views: models from plugin tabs get automatically materialized and bound to TabbableModel.CustomProperties[MyKey]. Extended the SmartModelBinder for this.
* (Developer) New event _ModelBoundEvent_. Consume this in plugins to persist plugin specific models.
* (Admin) Added _GMC_ tab to product edit view. This is more a coding example for the above stuff rather than a new feature.
* (Developer) Implemented _AdminThemedAttribute_: instructs the view engine to additionally search in the admin area for views. Very useful in larger plugin projects.
* (Developer) Enhanced _IMenuProvider_: menu items can now be injected to the public catalog menu
* (Developer) Implemented _IWidgetProvider_. Allows request scoped registration of action routes to be injectable into widget zones. Perfect for custom action filters.

* (Developer) New IoC method ContainerManager.InjectProperties()
* Implemented support for EU VAT regulation for digital goods (2008/8/EG directive)

	- jQuery UI to 1.11

	- Shows last error

* (Developer) Implemented _RunSync_ extension methods for _Func<Task>_ and _Func<Task<T>>_. A reliable way to execute async operations synchronously.
* (Developer) Refactored model creation for category navigation: it now incorporates _TreeNode<MenuItem>_, which enables plugin developers to alter the main menu with the event hook _NavigationModelBuilt_.
* (Developer) Added _user.less_ to Alpha theme for user defined css overrides and tweaks
* (Developer) Moved _PublicControllerBase_ to SmartStore.Web.Framework
* (Developer) Moved 'AdminControllerBase' to SmartStore.Web.Framework

	- Html.Add[Script|CssFile]Parts() now can handle already bundled resources correctly (no attempt is made to bundle them, the bundle's virtual url is returned instead)
