+### r8

+* Transport.seconds returns the progress in seconds. 
+* Buffer.from/toArray, Float32Array <-> Buffer conversions
+* Buffer.slice(start, end) slices and returns a subsection of the Buffer
+* Source.sync now syncs all subsequent calls to `start` and `stop` to the TransportTime instead of the AudioContext time. 
+	* e.g. source.sync().start(0).stop(0.8); //plays source between 0 and 0.8 of the Transport
+* Transport.on("start" / "stop") callbacks are invoked just before the event.
+* Param can accept an LFO description in the constructor or .value
+	* e.g. param.value = {min : 10, max : 20, frequency : 0.4}
+* Time.TimeBase has clone/copy methods.
+* Tone.Buffer.prototype.load returns Promise
+* Using Tone.Delay and Tone.Gain everywhere
+* Patch for Chrome 53+ issue of not correctly scheduling AudioParams with setValueAtTime
+* Panner3D and Tone.Listener wrap native PannerNode and AudioListener to give 3D panning ability.
