This page represents a comparison between Legacy Stack (aka "4.x" stack) vs Platform Stack (previously referred to as "Symfony" or "6.x" stack); it will be updated as new stack matures. Note: Features mentioned on the black list are still available in 5.x, but via legacy kernel so you will need to use "pure legacy" or a mixed setup using "legacy fallbacks". 

For a list of Symfony features supported out of the box, see here.

For additional related topics see Legacy code and features and Intro for eZ Publish 4.x/3.x developers.

Known existing integration (white list):

5.x Feature4.x FeatureNote/Limitation
Content Model
5.x aimed at not adding any features in the content/data model that would lead to backwards compatibility breaks, new features will instead be introduced when we reach "eZ Platform 1.0" and beyond.
Content*(Content) Object


(Content) Relation(Object) Relation 
Field(Object) AttributeMissing FieldTypes will cause eZ Publish to return exception, this can be avoided by implementing<TODO:Add link when article on this> the FieldType or configuring it as "NullType"
FieldTypeDataTypeSee FieldTypes reference for list of supported types, known unsupported FieldTypes are mentioned in Known issues




ContentType(Content) Class 
FieldDefinition(Content) Class Attribute 
FieldGroups(Content) Class Attribute Grouping 
UserGroup Can by design (and intention) only have one location in 5.x when using Public API UserService
RoleAssignment Currently not possible to delete specific assignment by id, can be deleted by Role and User.
Public APIn/aLegacy/4.x does not have a official public API, almost all internal functions are exposes publicly
REST API 5.1 and higher includes a working read/write REST v2 API, 4.x had a readonly REST v1 API as of 4.5
Development environmentDevelopment modeIn 5.x this is provided by Symfony, and web debugger is extended by eZ Publish.
Web stack 5.x web stack is Symfony with several eZ features on top
(Twig) Template system(eZ) Template system 
ViewProviderOverride systemRestricted to viewLocation in 5.0, viewContent added in 5.1, for changing presentation logic.
Controller overriden/a5.2 added feature for being able to also use override system of View Provider to also be able to override content controller under your own conditions to be able to modify behavior.
Theme systemDesign systemPlanned to use LiipThemeBundle, however as there is lack of caching and support for assets currently which is blocking us from using it easily.
HTTP CacheView- / Static- CacheFor anonymous users with content aware caching since 5.0, also for logged in users with context aware caching since 5.2
SiteAccessSite accessCustom Url, host, port and combination matching to a specific set of settings
SiteAccessGroupn/aNew in 5.x, grouping of related SiteAccesses and common settings for them, typically used to denote a "Site"
CSRFeZ FormTokenProvided by Symfony
Render + Query / API usefetch functionsCombining the render functionality of Symfony with Override system and API you are able to create reusable views of your content similarly to how you would use fetch functions in the past, but getting cache and view / logic separation handled in a native way.
Persistence cacheCluster- / Class- / ClassAttribute- / var- / "Global"- cacheIntroduced in 5.1, multi repository (aka multi-db) setups support added in 5.2.
IOCluster (-ing of files)Currently uses 4.x cluster system, new and simpler file clustering is planned for "eZ Platform 1.0" however this is abstracted away by the API and will only affect how cluster setups are configured.
Multi repositoryMulti-dbSupported, however see note on "Persistence cache", as of 5.3 with own "repository" configuration.

\* When referring a specific instance of any of the content model entries, either "object" or "item" is normal to append depending on context. In our BDD specifications the domain names have "object" appended to them forming "Content object(s)", "Location object(s)" and so on. 

Known missing in Symfony stack (black/grey list):

Note: Missing integration doesn't mean the system can not use the feature in a new installation relying on the new stack, but if it needs, it shall rely on a fallback to the legacy stack. For instance: a website with a shop system could be done in twig and rely on legacy only for the fallback for shop parts.

RatingUser Rating not currently supported by API (the service to deal with ratings, rating field type already exists), planned to be implemented later when some convention for FieldType provided API's are established.
ShopNo shop or field(/data) types related to shop currently supported by API, see Known issues. This is planned for "eZ Platform 1.x" or a release shortly thereafter, it will most likely use parts of Sylus for this functionality.
eZCommentezcomments was replaced in 5.2 with a CommentsBundle that will provide an agnostic system to integrate 3rd party comment services. Out of the box supporting Disqus and Facebook integration but can via custom integration also work with other 3rd party systems (example: service, content model based comments or even ezcomments)
Content EditingContent editing module is not implemented yet, but custom needs can for instance be solved with Public API+Symfony controllers or use of javascript REST client + REST API.
Module PermissionsController / Bundle Permissions is not fully integrated with eZ Publish Repository permission system yet, currently standard Symfony firewall rules need to be used. Public API however has full support for permissions and limitations, and is as of 5.2 known to support legacy most edge cases.
UrlAlias RoutingUrlAlias has the same model as before and hence does not support routing directly to a bundle:controller:action
WorkflowPlanned for future version, see Shop. Simple workflows already possible by using Symfony evens and Public API "Signals".
Information CollectorPlanned as a Form builder UI basically using Symfony Forms + swiftmailer for mail transport, might reuse content types similarly to how Information Collector did it.
Package systemPlanned to return as a import/export system which uses either API or SPI directly to replicate some or full amount of content from one repository to another, preferred format: XML using XML reader/writer.
Menu managementMenu system in Platform will use KnpMenu bundle, a light version is scheduled for 5.3 while a more deep integration is planned for 5.4.
PDF ExportNot currently planned, could be re-implemented outside of Core
RSS feedsCurrently no API for managing RSS feeds, REST view can be used as basis of feeds.
Frontend Editing

See "Content Editing".

Be aware that eZ Flow timeline feature is not available in the legacy admin (only in front end editing), hence not usable on the new stack.

PreviewComes with 5.3, versions before that uses legacy for preview.
SearchSearch API exists, but front end is currently using legacy fallback (ezfind & ezsearch) and 5.x Search API uses SQL for now while Solr implementation will be added in 2014.
User moduleUser login, login handlers and SSO handlers uses Symfony authentication system as of 5.3, change-password, forgot-password, register, profile and editing currently uses legacy fallback.
oAuth 2.0oAuth 1.0 supported in REST v1 in legacy, planned for new stack and REST v2 for future 5.x version.
Fetch aliasPlanned for future version as a way to specify a query with support for dynamic variables given to it. Currently also possible by means of OOP extending existing query functionality.
Extensions(aka Bundles)
eZ TagsPlanned for future 5.x version, still community supported in legacy stack on 5.x.
eZ SIeZ SI is purely legacy, not required in Symfony as it support ESI natively. ez SI is still supported in legacy stack on 5.x.
eZ Content stagingNo equivalent yet on the new stack, still supported in legacy stack on 5.x.
eZ Style editorNo equivalent on the new stack, still supported in legacy stack on 5.x up until 5.1.
eZ SurveyNo equivalent yet on the new stack, still supported in legacy stack on 5.x.
