My Tichome arrived well, and I'm enjoying it so far

What's Mobvoi's policy about Cast Firmware updates?
How fast and until when will updates be pushed to our Tichomes?
The current cast version on the Tichome is v1.25, while Google Home devices have v1. 28 (preventing us to use that new Assistant Broadcast function, for example). Is there a guy working on bridging that gap on your side?
Thanks in advance!
