 == How Schema Registry contexts work
+When you enable contexts, Schema Registry changes how it assigns schema IDs, resolves configuration, and interprets subject names.
 
 === Schema ID isolation
 
-Before contexts, the Schema Registry maintained a single global ID counter. All schemas shared one ID space, and a given schema ID pointed to exactly one schema across the entire registry.
+Prior to v26.1, the Schema Registry maintained a single global ID counter. All schemas shared one ID space, and a given schema ID pointed to exactly one schema across the entire registry.
 
-After enabling contexts, each context has its own independent ID counter. This means schema ID `1` in `.staging` and schema ID `1` in `.production` are different schemas. As a result (and by default), `GET /schemas/ids/{id}` searches the _default context only_. To retrieve a schema by ID from a non-default context, you must pass the `subject` query parameter to scope the lookup:
