-- 2018-12-01: 1.1 Release candidate announced. 
+- 2020-08-20: 1.1 Release candidate 2 released. 
+  - [Extensions](https://jsonapi.org/format/1.1/#extensions) were added and the
+    scope of [profiles](https://jsonapi.org/format/1.1/#profiles) were reduced
+    since their introduction in RC1.
+  - [Links](https://github.com/json-api/json-api/pull/1348) can be represented
+    as [RFC 8288](https://tools.ietf.org/html/rfc8288)-style web links.
+  - A new [`describedby`](https://github.com/json-api/json-api/pull/1447) [links member](https://jsonapi.org/format/1.1/#document-top-level)
+    was added so that implementors can incorporate description documents (e.g.
+    [OpenAPI](https://www.openapis.org/) or [JSON Schema](https://json-schema.org/specification.html))
+    directly into their APIs.
+  - [Local IDs](https://jsonapi.org/format/1.1/#document-resource-object-identification)
+    were [introduced](https://github.com/json-api/json-api/pull/1244) so that a
+    client can create a relationship to a resource yet-to-be created by the
+    same request.
+- 2018-12-01: 1.1 Release candidate 1 released.
   - New features include: [profiles](https://jsonapi.org/format/1.1/#profiles), ["@-Members"](https://jsonapi.org/format/1.1/#document-member-names-at-members), and [error object `type` links](https://jsonapi.org/format/1.1/#error-objects). 
   - There are editorial clarifications around: [query parameters](https://jsonapi.org/format/1.1/#query-parameters) (their parsing/serialization, and reserved parameter names), the appropriate status code for [specific](https://github.com/json-api/json-api/pull/1036) [responses](https://github.com/json-api/json-api/pull/1029), and the [presence of the `included` key](https://github.com/json-api/json-api/pull/1236) even when its value is an empty array.
   - JSON:API switched to [recommending camelCased names](https://jsonapi.org/recommendations/#naming).
