Google has announced a new Preview Program for Chromecast devices. They are also quick to point out that this is not a beta program. This opt-in program updates your Chromecast to the latest firmware prior to the wide release, but these updates are said to be of the same quality as production updates. Members of the program can expect their updates to arrive shortly before the full push of the official production firmwares. In essence, joining the program gives you a word in the last say before the latest update hits all Chromecast devices, as Google is looking for feedback. Feedback can be submitted from iOS, Android, or your computer. Steps for each are listed at Share feedback about Chromecast - Chromecast Help All Chromecast devices (1st and 2nd gen, Audio) are eligible for the program. If you're interested, visit this link for FAQs and more info: Chromecast Preview Program overview - Chromecast Help or follow the steps below to jump right in (from the FAQ page).
