## Upgrading ##

### New user interface for CMS ###

Most aspects of the interface have been redesigned, which necessitated a substantial
redevelopment of the underlying logic and presentation. 
If you have customized the admin interface in any way, please review
the detailed changelog for this release. Many interface components have changed completely,
unfortunately there is no clear upgrade path for every interface detail.
As a starting point, have a look at the new templates in `cms/templates`
and `sapphire/admin/templates`, as well as the new [jQuery.entwine](https://github.com/hafriedlander/jquery.entwine) 
based JavaScript logic. Have a look at the new ["Extending the CMS" guide](../howto/extending-the-cms),
["CSS" guide](../topics/css) and ["JavaScript" guide](../topics/javascript) to get you started.

### New tree library ###

The page tree moved from a bespoke tree library to [JSTree](http://jstree.com),
which required changes to markup of the tree and its JavaScript architecture.
This includes changes to `TreeDropdownField` and `TreeMultiSelectField`.

### Settings-related fields move from `SiteTree->getCMSFields()` to new `SiteTree->getSettingsFields()` ###

The fields and tabs are now split into two separate forms, which required a structural
change to the underlying class logic. In case you have added or removed fields
in the "Behaviour" or "Access" tab, please move these customizations to a new `getSettingsFields()` method.
In case of SiteTree extension through `updateCMSFields()` and a decorator/extension,
please use the new `updateSettingsFields()` instead.

### New `SiteTree::$description` field to describe purpose of a page type ###

Please use this static property to describe the purpose of your page types,
which will help users understand the new "Add page" dialog.
For example, a `TeamPage` type could be described as "Lists all team members, linking to their profiles".
Note: This property is optional (defaults to an empty string), but its usage is highly encouraged.

### Stylesheet preprocessing via SCSS and the "compass" module ###

CSS files in the `cms` and `sapphire/admin` modules are now generated through
the ["compass" SilverStripe module](http://silverstripe.org/compass-module), which uses
the ["Compass" framework](http://compass-style.org/) and the ["SCSS" language](http://sass-lang.com/).
This allows us to build more flexible and expressive stylesheets as a foundation for any
extensions to the CMS interface. 

The "compass" module is only required if core stylesheets are modified,
not when simply using the CMS or developing other CMS functionality.
If you want to extend the CMS stylesheets for your own projects without SCSS,
please create a new CSS file and link it into the CMS via `[api:LeftAndMain::require_css()]`.

### Restructured files and folders ###

In order to make the `sapphire` framework useable without the `cms` module,
we've moved some files around. 

CMS base functionality which is not directly related to content pages (`SiteTree`) 
has been moved from the `cms` module into a new "sub-module" located in `sapphire/admin`. 
This includes generic management interfaces like "Files & Images" (`AssetAdmin`),
"Security" (`SecurityAdmin`) and the `ModelAdmin` class.
On the other hand, `SiteTree` related features were moved from `sapphire` to the `cms` module.

Due to the built-in PHP class autoloader,
this usually won't have any effect on your own code (unless you're including direct file paths).
For any other files (CSS files, templates, images, JavaScript) which might
be referenced by their path, please doublecheck that their path is still valid.

### Moved `Translatable` extension into new 'translatable' module ###

If you are translating your `SiteTree` or `DataObject` classes with the `Translatable`
extension, please install the new module from `http://silverstripe.org/translatable-module`.
The following settings can be removed from your own `_config.php`, as they're automatically
included through `translatable/_config.php`:

	Object::add_extension('SiteTree', 'Translatable');
	Object::add_extension('SiteConfig', 'Translatable');
	
### Removed "auto-merging" of member records from `Member->onBeforeWrite()`

Due to security reasons. Please use `DataObject->merge()` explicitly if this is desired behaviour.

### Unit tests require definition of used `DataObject` and `Extension` classes ###

This change was necessary in order to improve performance of the test framework,
and avoid rebuilding the database where no database access is required.
It also won't build any `DataObject` subclasses implementing the `TestOnly` interface,
unless these are explicitly noted.

 * `SapphireTest->extraDataObjects`: List all `TestOnly` classes relevant to your test class here.
 * `SapphireTest->requiredExtensions`: Maps `DataObject` classes to an array of required extensions.
   Example: `array("MyTreeDataObject" => array("Versioned", "Hierarchy"))`
 * `SapphireTest->illegalExtensions`: Does the reverse of `requiredExtensions`: Removes already applied extensions.

Alternatively, you can enforce database usage by setting `SapphireTest->usesDatabase` to `TRUE` in your test class.

### Renamed Classes ###

 * `DataObjectDecorator`: Use `DataExtension` instead (the class doesn't implement the [GOF "Decorator" pattern](http://en.wikipedia.org/wiki/Decorator_pattern))
 * `MySQLFulltextSearchable`: Use `FulltextSearchable` instead
 * `CMSMainMarkingFilter`: Use `CMSSiteTreeFilter_Search` instead * 

### Removed Classes ###

 * `ConfirmedFormAction`
 * `QueuedEmail`, `QueuedEmailDispatchTask`
 * `RestrictedTextField`, `UniqueTextField`, `UniqueRestrictedTextField`, `AutocompleteTextField`: Use custom fields instead
