According to internal documents obtained by 9to5Google, Google is set to finally release a new Chromecast later this month. The new device will reportedly have improved wifi, which could mean 802.11ac, and new features. One of those new features is something being called “Fast Play” which will make it quicker and easier to connect to the new Chromecast. Another feature called Chromecast Audio will allow the device to connect to speakers through an auxiliary cable and sync the audio from multiple Chromecasts. The new device will reportedly be announced at Google’s event on September 29th, where they’re expected to also reveal their two new Nexus phones.
