5.1 Release Notes
eZ Publish 5.1 is our most Scalable, most Stable and most Feature Rich eZ Publish 5.x version & eZ Publish version to date. Either if you intend to start using the 5.x API & Symfony stack or if you plan to use legacy and pure 4.x functionality, this is our recommend LTS release.
Architecture overview as of 5.1
Just like 5.0, 5.1 consists of a “Dual-kernel”. On the left side you’ll see the legacy stack, an enhanced and stabilized version of the 4.x kernel. On the right side is the 5.x stack, with the arrows indicating some highlighted improvements made since 5.0.
Highlighted 5.1 features in 5.x stack
IO Clustering support for use with legacy DFS
Persistence DB cache using Stash
This feature enhances performance and clustering scalability by sitting between the API and the database storage engine and in default setup cache everything but search queries lowering load of backend considerably. [ PR, Doc ]

One of the steps done in this release that makes it possible to use 5.x stack fully for content rendering with standard fieldtypes without having to use legacy fallback as was the case in 5.0. [ PR, Doc ]
