 Change Log
 ==========
 
+## Version 1.11.0
+
+_2020-10-04_
+
+ * New: Kotlin extension functions and properties. Use of these extensions is only possible from
+   Kotlin, and requires the Kotlin stdlib dependency. This release does not have any Kotlin
+   requirement and can be used Kotlin-free from Java.
+
+    ```kotlin
+    /** Extension alternative to [Types.nextAnnotations()]. */
+    fun <reified T : Annotation> Set<Annotation>.nextAnnotations(): Set<Annotation>?
+ 
+    /** Extension alternative to [Types.getRawType()]. */
+    val Type.rawType: Class<*>
+ 
+    /** Extension alternative to [Types.arrayOf()]. */
+    fun KClass<*>.asArrayType(): GenericArrayType
+ 
+    /** Extension alternative to [Types.arrayOf()]. */
+    fun Type.asArrayType(): GenericArrayType
+    ```
+ 
+ * New: Experimental Kotlin extensions. These depend on unreleased APIs and may break in a future 
+   release of Kotlin. If you are comfortable with this, add `@ExperimentalStdlibApi` at the callsite
+   or add this argument to your Kotlin compiler: `"-Xopt-in=kotlin.ExperimentalStdlibApi"`.
+     
+    ```kotlin
+    /** Returns the adapter for [T]. */
+    inline fun <reified T> Moshi.adapter(): JsonAdapter<T>
+
+    /** Returns the adapter for [ktype]. */
+    fun <T> Moshi.adapter(ktype: KType): JsonAdapter<T>
+
+    /** Adds an adapter for [T]. */
+    inline fun <reified T> Moshi.Builder.addAdapter(adapter: JsonAdapter<T>): Moshi.Builder
+
+    /** Extension alternative to [Types.arrayOf()]. */
+    fun KType.asArrayType(): GenericArrayType
+
+    /** Extension alternative to [Types.subtypeOf()]. */
+    inline fun <reified T> subtypeOf(): WildcardType
+
+    /** Extension alternative to [Types.supertypeOf()]. */
+    inline fun <reified T> supertypeOf(): WildcardType
+    ```
+   
+ * New: `JsonReader.nextSource()`. This returns an Okio `BufferedSource` that streams the UTF-8
+   bytes of a JSON value. Use this to accept JSON values without decoding them, to delegate to
+   another JSON processor, or for streaming access to very large embedded values.
+ * New: `Moshi.Builder.addLast()`. Use this when installing widely-applicable adapter factories like
+   `KotlinJsonAdapterFactory`. Adapters registered with `add()` are preferred (in the order they
+   were added), followed by all adapters registered with `addLast()` (also in the order they were
+   added). This precedence is retained when `Moshi.newBuilder()` is used.
+ * New: `setTag()`, `tag()` methods on `JsonReader` and `JsonWriter`. Use these as a side-channel
+   between adapters and their uses. For example, a tag may be used to track use of unexpected
+   data in a custom adapter.
+ * Fix: Don't crash with a `StackOverflowError` decoding backward-referencing type variables in
+   Kotlin. This caused problems for parameterized types like `MyInterface<E : Enum<E>>`.
+ * Upgrade: [Okio 1.17.5][okio_1_7_5].
+ * Upgrade: [Kotlin 1.4.10][kotlin_1_4_10].
+
