The longread editor moved to a block model
What changed on June 4: the longread editor moved to a block document model with preview and document controls.
Why it matters
On June 4, the longread editor moved to a document made of separate blocks. It gained a document controller, block editing, insertion, preview, and a route to final details.
Follow-up changes removed the permanent inline toolbar and limited formatting actions to text blocks so media blocks do not expose unsuitable controls.
Document state, preview, return behavior, and reduced motion have focused widget coverage. This June entry does not provide a separate rendered physical-device check.
