-## 2.1.1-dev.3.2
+## 2.1.1 - 2019-02-18
 
-* Cherry-pick 9d25cc93e850d4717cdc9e1c4bd3623e09c16d47 to dev
+This is a minor version release. Again, the team's focus was mostly on improving
+performance and stability after the large changes in Dart 2.0.0. In particular,
+dart2js now always uses the "fast startup" emitter and the old emitter has been
+removed.
 
-## 2.1.1-dev.3.1
+There are a couple of very minor **breaking changes:**
 
-* Cherry-pick 46080dd886a622c5520895d49c97506ecedb1df8 to dev
-* Cherry-pick fc62cf037343248c5ace87629d8eb1063f9f2428 to dev

-* Cherry-pick 957e194735bda4fcf06cdcc68fa80f3290b17d79 to dev
+*   In `dart:io`, adding to a closed `IOSink` now throws a `StateError`.
 
-## 2.1.1-dev.3.0
+*   On the Dart VM, a soundness hole when using `dart:mirrors` to reflectively
+    invoke a method in an incorrect way that violates its static types has
+    been fixed (Issue [35611][]).
 
-* Cherry-pick 3cb16d20e7810a2a378bb897d939f67c0b380d88 to dev

+#### `dart:html`
 
-#### Analyzer
+*   Added methods `Element.removeAttribute`, `Element.removeAttributeNS`,
+    `Element.hasAttribute` and `Element.hasAttributeNS`. (Issue [35655][]).
+*   Improved dart2js compilation of `element.attributes.remove(name)` to
+    generate `element.removeAttribute(name)`, so that there is no performance
+    reason to migrate to the above methods.
+*   Fixed a number of `dart:html` bugs:
 
-*   New hints added:
+    *   Fixed HTML API's with callback typedef to correctly convert Dart
+        functions to JS functions (Issue [35484]).
+    *   HttpStatus constants exposed in `dart:html` (Issue [34318]).
+    *   Expose DomName `ondblclick` and `dblclickEvent` for Angular analyzer.
+    *   Fixed `removeAll` on `classes`; `elements` parameter should be
+        `Iterable<Object>` to match Set's `removeAll` not `Iterable<E>` (Issue
+        [30278]).
+    *   Fixed a number of methods on DataTransferItem, Entry, FileEntry and
+        DirectoryEntry which previously returned NativeJavaScriptObject.  This
+        fixes handling drag/drop of files/directories (Issue [35510]).
+    *   Added ability to allow local file access from Chrome browser in ddb.
 
-    *   `NON_CONST_CALL_TO_LITERAL_CONSTRUCTOR` and
-        `NON_CONST_CALL_TO_LITERAL_CONSTRUCTOR_USING_NEW` when a `@literal`
-        const constructor is called in a non-const context (or with `new`).

-* `--fast-startup` is forced on.  The flag is silently ignored and will be

+*   **Breaking Change:** Adding to a closed `IOSink` now throws a `StateError`.
+*   Added ability to get and set low level socket options.
 
-  The alternative 'full emitter' is no longer available. The generated code for
-  `--fast-startup` is optimized to load faster, even though it can be slightly

-### Tool Changes
+### Dart for the Web
+
+#### dart2js
+
+*   The old "full emitter" back-end is removed and dart2js always uses the "fast
+    startup" back-end. The generated fast startup code is optimized to load
+    faster, even though it can be slightly larger. The `--fast-startup` and
+    `--no-fast-startup` are allowed but ignored. They will be removed in a
+    future version.
+
+*   We fixed a bug in how deferred constructor calls were incorrectly not marked
+    as deferred. The old behavior didn't cause breakages, but was imprecise and
+    pushed more code to the main output unit.
+
+*   A new deferred split algorithm implementation was added.
+
+    This implementation fixes a soundness bug and addresses performance issues
+    of the previous implementation, because of that it can have a visible impact
+    on apps. In particular:
+
+    *   We fixed a performance issue which was introduced when we migrated to
+        the common front-end. On large apps, the fix can cut 2/3 of the time
+        spent on this task.
+
+    *   We fixed a bug in how inferred types were categorized (Issue [35311][]).
+        The old behavior was unsound and could produce broken programs. The fix
+        may cause more code to be pulled into the main output unit.
+
+        This shows up frequently when returning deferred values from closures
+        since the closure's inferred return type is the deferred type. For
+        example, if you have:
+
+        ```dart
+        () async {
+          await deferred_prefix.loadLibrary();
+          return new deferred_prefix.Foo();
+        }
+        ```
+
+        The closure's return type is `Future<Foo>`. The old implementation
+        defers `Foo`, and incorrectly makes the return type `Future<dynamic>`.
+        This may break in places where the correct type is expected.
+
+        The new implementation will not defer `Foo`, and will place it in the
+        main output unit. If your intent is to defer it, then you need to ensure
+        the return type is not inferred to be `Foo`. For example, you can do so
+        by changing the code to a named closure with a declared type, or by
+        ensuring that the return expression has the type you want, like:
+
+        ```dart
+        () async {
+          await deferred_prefix.loadLibrary();
+          return new deferred_prefix.Foo() as dynamic;
+        }
+        ```
+
+        Because the new implementation might require you to inspect and fix your
+        app, we exposed two temporary flags:
+
+    *   The `--report-invalid-deferred-types` causes dart2js to run both the
+        old and new algorithms and report any cases where an invalid type was
+        detected.
+
+    *   The `--new-deferred-split` flag enables this new algorithm.
+
+*   The `--categories=*` flag is being replaced. `--categories=all` was only
+    used for testing and it is no longer supported. `--categories=Server`
+    continues to work at this time but it is deprecated, please use
+    `--server-mode` instead.
+
+*   The `--library-root` flag was replaced by `--libraries-spec`. This flag is
+    rarely used by developers invoking dart2js directly. It's important for
+    integrating dart2js with build systems. See `--help` for more details on the
+    new flag.
