This page represent a comparison between Legacy Stack vs 5.x New Stack (aka Symfony Stack, aka 6.x Stack).
This means that features mentioned on the black list are still available in 5.x, but only via legacy kernel so you will need to use only legacy or a mix of both. 


Known existing integration (white list):

Feature4.x nameNotes
Content Model 5.x aimed at not adding any features in the content/data model to make sure no breaks happened in 4.x, new features will instead be introduced as we approach 6.x with new storage engines that can support them

Multi RepositoryMulti-dbSome features, notably Persistence cache got support for this in 5.2

Known missing


in Symfony stack (black list):

noteNote: 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 and the legacy kernel. For instance: a website with a shop system could be done in twig and rely on legacy only for the fallback.
