A new OTA is rolling out now/imminently with build number 16664.
It's meant to bring the usual bugs and stability fixes (not sure what the deal is with that, chromecast is the stablest device I own), DNS improvements, improved IPV6 support and it will now retain volume levels across sessions.
Basically, if your TV is at full volume, you won't deafen yourself when you start casting something to your TV (provided chromecast wasn't at full volume previously).
