#  2.4.0 (2010-05-05)

##  Overview

 * Support for hierarchical URLs
 * Support for MSSQL server database abstraction (via a separate module)
 * A "SiteConfig" record stores site-wide settings and default permissions and author groups for pages
 * "Permission Roles" are a simple way to combine multiple permission codes and assign them to groups in the Security interface. This makes permissions easier to maintain and less repetitive to set up.
 * The CMS searches for broken internal links to other pages and broken file references, and highlights them in the WYSIWYG editor
 * Dramatically reduced memory usage in CMS tree on larger sites (10,000+)
 * Performance improvements around Object and ViewableData property access.
 * Improved Shortcode API to allow for custom tag parsing in CMS content
 * More fine-grained permission control for translators
 * Improved unit test execution speed, increased number of tests cases by 30%
 * Better XSS security of the autologin token by using HTTPOnly cookies, more secure brute force login restrictions
 * Decreased memory usage in "Files & Images" section
 * Support for SQLite and PostgreSQL databases (via separate module)
 * Partial caching in templates, to allow for faster load times of certain aspects in dynamic pages.
 * Upload controls in the CMS no longer require the Adobe Flash plugin, and work again on Mac OSX.
 * File and page dropdown selections support inline searching, to make handling larger tree structures easier.
 * Fixed password hashing design flaw, which makes SilverStripe databases more portable between different server architectures.
 * Improved reporting API to unify the CMS sidebar reports and full-page reports on their own section. Its easier to add custom filters to reports.
 * Batch action handling handles larger tree structures, provides better visual feedback, and respects permissions on individual pages.
 * Global site configuration is translatable, meaning titles for your website can be in different languages without any switching in your templates.
 * Allow selection of themes through the site configuration interface (in addition to changing the theme via configuration code)
 * More fine-grained translation permissions: A group can be limited to only edit a certain language in the CMS.
 * Added dropdown to choose from existing anchor links when inserting a link from the CMS sidebar.
 * Team members can get permissions to see the draft version of a page in preview mode without requiring CMS access.
 * Pages of type "Virtual Page" have improved stability in regards to their permission control, translation and publication.
 * Improved broken link detection (''talk to Andy for more info'')
 * Removed the jsparty/ toplevel folder, and moved all its dependencies into sapphire/thirdparty and cms/thirdparty
 * More than 350 bugfix and enhancement commits, and 200 minor changes.

## Upgrading

In preparation for the pending release of 2.4.0 the following page contains all the information you need to know about
the changes that have been undertaken.

This page **doesn't include new features of 2.4.0** as such, just functionality that has changed or been removed since
2.3.

Before you start upgrading you should always backup your site directory and the database. Once you have a backup made
remove the `cms/`, `sapphire/` and `jsparty/` folders then copy in the new `cms/` and `sapphire/` folders from
your 2.4 download.


### Removed jsparty

The rather unorganised top level `jsparty/` folder has been removed from the core distribution and files separated to `cms/thirdparty` and `sapphire/thirdparty`. If your custom code referred to files in `jsparty` you will have to
update the links to the new location (either `sapphire/thirdparty/` or `cms/thirdparty/`). 

Thirdparty files which aren't used in any core features have also been removed such as jquery-validate. If you reference
any files at all from `jsparty` you should double check your paths.

### Removed Classes

As part of our effort to tidy the core product we have removed several classes which we believed didn't warrant
inclusion in the official release. They either were out of date functionality or superseded or just didn't justify
inclusion. Where needed we have moved the files to individual modules. Also note several field types which were due for
deprecating have been kept due to use within the CMS (''UniqueTextField'', `UniqueRestrictedTextField`). These however
are going to be removed for the next major release.

 | Class name                               | | Comment  | 
 | ----------                               | | -------  | 
 | `AjaxFormAction`                       | |          |
 | `BankAccountField`                     | | moved to [formfields_nz](http://open.silverstripe.org/browser/modules/formfields_nz) module | 
 | `CalendarDateField`                    | | use `DateField` with ''setConfig('showcalendar', true)'', moved to [legacydatetimefields](http://open.silverstripe.org/browser/modules/legacydatetimefields/trunk) module | 
 | `CompositeDateField`, `DMYDateField` | | use `DateField` with ''setConfig('dmyfields', true)'', moved to [legacydatetimefields](http://open.silverstripe.org/browser/modules/legacydatetimefields/trunk) module    | 
 | `ConfirmedFormAction`                  | |          |
 | `DMYDateField`                         | |          |
 | `DropdownTimeField`                    | | use `TimeField` with ''setConfig('showdropdown', true)'', moved to [legacydatetimefields](http://open.silverstripe.org/browser/modules/legacydatetimefields/trunk) module | 
 | `Email_Template`                       | | use `Email` instead | 
 | `GhostPage`                            | |          |
 | `GSTNumberField`                       | | moved to [formfields_nz](http://open.silverstripe.org/browser/modules/formfields_nz) module | 
 | `HiddenFieldGroup`                     | |          |
 | `PDODatabase`                          | |          |
 | `PermissionDropdownField`              | |          |
 | `PopupDateTimeField`                   | | use `DatetimeField`, moved to [legacydatetimefields](http://open.silverstripe.org/browser/modules/legacydatetimefields/trunk) module | 
 | `ReportField`                          | |          |
 | `TypeDropdown`                         | |          |


Some date/time field implementations were completely refactored, and their old implementations moved to the
[legacydatetimefields](http://open.silverstripe.org/browser/modules/legacydatetimefields/trunk) module:

 | Class name          | | Comment                                                                         | 
 | ----------          | |-------                                                                          | 
 | `LegacyDateField` | | old version of `DateField`, renamed to avoid conflicts with new `DateField` | 
 | `LegacyTimeField` | | old version of `TimeField`, renamed to avoid conflicts with new `TimeField` | 

### Removed SWFUpload

SWFUpload has been removed from the core package due to ongoing issues with supporting it. The CMS Content Editors
upload has been rewritten to use jQuery so no 2.3 functionality has been lost but if your module made use of this
library, then you will need to bundle it within your module. Related files which have been removed as a side effect of
this - `Upload.js`, `TinyMCEImageEnhancements.js`, `SWF_Upload.js` and `CMSMain_Upload.js`.

### Renamed Classes

We undertook some major work to reduce classname conflicts. Some classes have been namespaced with 'SS' to reduce
conflicts with other code. A couple notes - even though the classes have been renamed to `SS_`<ClassName>` the class is
still contained within the `ClassName.php'' file (no `SS_` prefix)


 | Original class name        | | New class name                | 
 | -------------------        | | --------------                | 
 | `Report`                 | | `SS_Report`                 | 
 | `HTTPRequest`            | | `SS_HTTPRequest`            | 
 | `HTTPResponse`           | | `SS_HTTPResponse`           | 
 | `HTTPResponse_Exception` | | `SS_HTTPResponse_Exception` | 
 | `Database`               | | `SS_Database`               | 
 | `Query`                  | | `SS_Query`                  | 
 | `SSDateTime`             | | `SS_Datetime`               | 
 | `Backtrace`              | | `SS_Backtrace`              | 
 | `Cli`                    | | `SS_Cli`                    | 
 | `Log`                    | | `SS_Log`                    | 
 | `LogEmailWriter`         | | `SS_LogEmailWriter`         | 
 | `LogErrorEmailFormatter` | | `SS_LogErrorEmailFormatter` | 
 | `LogErrorFileFormatter`  | | `SS_LogErrorFileFormatter`  | 
 | `LogFileWriter`          | | `SS_LogFileWriter`          | 
 | `ZendLog`                | | `SS_ZendLog`                | 
 | `HTMLValue`              | | `SS_HTMLValue`              | 

### Nested URLs enabled by default

When using our installer, the "nested URLs" feature will be enabled by default by a setting in *mysite/_config.php* (see
[blog
post](http://www.silverstripe.org/preview-of-silverstripe-2-4-hierarchical-urls-a-developer-community-contribution/)).
You can enable it manually for existing websites. Existing URLs will automatically change to the nested format without
republication (your old URLs should redirect automatically).

	:::php
	SiteTree::enable_nested_urls();


### SiteTree->Link() instead of SiteTree->URLSegment

Relating to the "nested URLs" feature, all *SiteTree* URLs should be accessed via *SiteTree->Link()* instead of using
the property *SiteTree->URLSegment* directly.

### Removed SiteTree::$add_action
 `$add_action` on Pages has been removed. If you want to define your own custom title for pages then you use
"`<myclassname>`.TITLE" in the i18n language tables instead or define your add action using `singular_name()`

	:::php
	// using the lang tables
	$lang['en_US']['RedirectorPage']['TITLE'] = "Redirector Page";


	// using singular_name()
	function singular_name() { return "Redirector Page"; }


### Removed dev/reset

Use `dev/tests/startsession` to create a new temporary database, or custom database tools like phpMyAdmin to
completely drop a database.


### Registering reports through SS_Report::register()

Removed `ReportAdmin->getReportClassNames()` in favour of `SS_Report::register()` to add custom reports to the CMS
(see [r98175](http://open.silverstripe.org/changeset/98175), [r98215](http://open.silverstripe.org/changeset/98215))

	:::php
	// in your _config file
	SS_Report::register("SideReport", "SideReport_NameOfReport");

### Fulltext Search and Indexes disabled by default

As of SilverStripe  2.4.0, no search engine is included by default. If you want to use a search engine, you should
enable it with this command in your _config.php:

	:::php
	FulltextSearchable::enable();


This will add a *SearchForm()* and *results()* method in your *Page_Controller*, as well as set up common fields
like SiteTree.Content to be indexed.

Note: Results may vary with database drivers other than *MySQLDatabase*. 

### Object Extension Instances

When working with extension instances directly on the extended object, please use the new *getExtensionInstances()*
getter. You need to manually call *setOwner($this)* before using the instance. 

Base setup:

	:::php
	class MyExtension extends Extension {
	  function myExtensionMethod() { // ... }
	}
	Object::add_extension('MyObject', 'MyExtension');


Wrong:

	:::php
	class MyObject extends DataObject {
	  function myExtensionMethod() {
	    $ext = $this->extension_instances['MyExtension'];
	    return $ext->myExtensionMethod();
	  }
	}


Right:

	:::php
	class MyObject extends DataObject {
	  function myExtensionMethod() {
	    $ext = $this->getExtensionInstance('MyExtension');
	    $ext->setOwner($this);
	    $ext->myExtensionMethod();
	  }
	}

### HTMLEditorField (TinyMCE) stores content as UTF8 instead of HTML Entities

Prior to 2.4.0, the TinyMCE JavaScript library would store a subset of special characters as HTML entities (see [TinyMCE
Configuration](http://wiki.moxiecode.com/index.php/TinyMCE:Configuration/entities)). SilverStripe expects UTF8 for user
input in the CMS, database storage as well as output. We have made this behaviour more consistent by converting the
TinyMCE entities back into UTF8 for database storage. 

### MySQL character set to UTF8 on new installations

The MySQL character set for SilverStripe used to be the database default (often "latin1", sometimes "utf8"). While all
textual database columns created by SilverStripe have been storing their content as "utf8" already in earlier releases,
MySQL fulltext search might not return the desired results with special characters (see
[#3582](http://open.silverstripe.org/ticket/3582)).

For new installations with a MySQL database backend, this will be set automatically to "utf8" by the installer in

*mysite/_config.php*. For existing sites built with SilverStripe 2.3, add the following code to your
*mysite/_config.php*.

	:::php
	MySQLDatabase::set_connection_charset('utf8');


No conversion of existing database schemas or content should be necessary.

### MySQL 5.0+ or newer required

See [server-requirements](/installation/server-requirements).

### BASE_PATH constant

Use `BASE_PATH` and `BASE_URL` instead of data from `$_SERVER` to calculate the base script path.

### Interface Change: "Site Content" tab renamed to "Pages"

The headlines of the left-hand tree panels have been changed accordingly.

### Data Migration: Files and Images

Existing files and images inside the Assets folder may not be displayed when you visit the 'Files & Images' tab in the
CMS.  If you get an error message when clicking through the folders in the site tree, this can be resolved by deleting
the content in the 'File' table in the database, and then clicking the 'Look for new files' button.

### Data Migration: User-defined forms

If you get errors in the User-define forms module, check that there is no column called 'CustomParameter' present in
either of the 'EditableFormField', 'EditableFormField_Live' or 'EditableFormField_versions' tables.

You need to login to your database management system (for example phpmyadmin) and delete the 'CustomParameter' column
from the EditableFormField table.

 * [rev:99360] $timeformat constructor parameter in TimeField needs to be in ISO date notation (not PHP's date())
