* Added `Timeline` class for interacting with Observatory's timeline feature.
* Added `ServiceExtensionHandler`, `ServiceExtensionResponse`, and `registerExtension` which enable developers to provide their own VM service protocol extensions.
* `dart:html`, `dart:indexed_db`, `dart:svg`, `dart:web_audio`, `dart:web_gl`, `dart:web_sql`
* The return type of some APIs changed from `double` to `num`. Dartium is now
using
JS interop for most operations. JS does not distinguish between numeric
types, and will return a number as an int if it fits in an int. This will
mostly cause an error if you assign to something typed `double` in
checked mode. You may
need to insert a `toDouble()` call or accept `num`. Examples of APIs that
are affected include `Element.getBoundingClientRect` and
`TextMetrics.width`.
* `dart:io`
* **Breaking:** Secure networking has changed, replacing the NSS library
with the BoringSSL library. `SecureSocket`, `SecureServerSocket`,

of a number of issues uncovered by the first few non-observatory
clients. This is a potentially breaking change for clients.
* Dartium has been substantially changed. Rather than using C++ calls into
Chromium internals for DOM operations it now uses JS interop.
The DOM objects in `dart:html` and related libraries now wrap
a JavaScript object and delegate operations to it. This should be
mostly transparent to users. However, performance and memory characteristics
may be different from previous versions. There may be some changes in which
DOM objects are wrapped as Dart objects. For example, if you get a reference
to a Window object, even through JS interop, you will always see it as a
Dart Window, even when used cross-frame. We expect the change to using
JS interop will make it much simpler to update to new Chrome versions.
