-### Refs in Rule Heads
+This release contains a mix of bugfixes, optimizations, and new features.
+
+### New language feature: refs in rule heads
 
 With this version of OPA, we can use a shorthand for defining deeply-nested structures
 in Rego:
@@ -109,13 +111,158 @@ This rule defines the same structure, but with multiple values instead of a key:
     "repos": {
       "get": {
         "endpoint": ["/v1/data"]
-        }
       }
     }
   }
 }
 ```
 
+To ensure that it's safe to build OPA policies for older OPA versions, a new
+capabilities field was introduced: "features". It's a free-form string array:
+
+```json
+{
+  "features": [
+    "rule_head_ref_string_prefixes"
+  ]
+}
+```
+
+If this key is not present, the compiler will reject ref-heads. This could be
+case when building bundles for older OPA version using their capabilities.
+
+
+### Entrypoint annotations in rule metadata
+
+It is now possible to annotate a rule with `entrypoint: true`, and it will
+automatically be picked up by the tooling that expected `--entrypoint` (`-e`)
+parameters before.
+
+For example, to build this rego policy into a wasm module, you had to pass
+an entrypoint:
+
+```rego
+package test
+allow {
+    input.x
+}
+```
+- `opa build --target wasm --entrypoint test/allow policy.rego`
+
+With the annotation:
+```rego
+package test
+
+# METADATA
+# entrypoint: true
+allow {
+    input.x
+}
+```
+- `opa build --target wasm policy.rego`
+
+The places where entrypoints are taken from metadata are:
+
+1. Building optimized bundles
+2. Building Wasm bundles
+3. Building Plan bundles
+4. Using optimization with `opa eval`
+
+Knowing a module's entrypoints can also help in different analysis tasks.
+
+### New Built-in Functon: `graphql.schema_is_valid`
+
+The new built-in allows checking schemas:
+
+```rego
+schema := `
+  extend type User {
+      id: ID!
+  }
+  extend type Product {
+      upc: String!
+  }
+  union _Entity = Product | User
+  extend type Query {
+    entity: _Entity
+  }
+`
+valid_schema_example {
+    graphql.schema_is_valid(schema)
+}
+```
+
+Requested by @olegroom.
+
+### New Built-in Functon: `net.cidr_is_valid`
+
+The new built-in function allows checking if a string is a valid CIDR.
+
+```rego
+valid_cidr_example {
+	net.cidr_is_valid("192.168.0.0/24")
+}
+```
