New Dart Editor Release with Dedicated WebGL Library

Eric Clayberg fills us in on the release details:

A new Dart Editor build is available at www.dartlang.org/editor. Changes include:

• New preference to disable auto-activation of code completion.
• Theme preview works with new analysis engine.
• Many performance and memory improvements with new analysis engine.

Breaking Change List:

• Existing base64 encoder method CryptoUtils.bytesToBase64(List<int> bytes, [int lineLength]) is changed to CryptoUtils.bytesToBase64(List<int> bytes, {bool urlSafe : false, bool addLineSeparator : false})
• Remove the (long deprecated) List.addLast method.
• Stream subscriptions are now more lenient about calling methods after canceling and resuming when not paused - it's no longer an error, it just doesn't do anything.
• WebGL types have been moved out of dart:html and into dart:web_gl. All WebGL prefixes have been removed (WebGLRenderingContext is now RenderingContext).
• dart:html’s WheelEvent.deltaX and deltaY values have been inverted on all browsers except Firefox for consistency and spec conformance.
• StrinkSink.writeAll now takes an optional separator argument.
• Iterable.reduce has been renamed to Iterable.fold. Same for Stream.
