Most up to date Roav Bolt Firmware version?

I was wondering what the most up to date firmware version for the Bolt was.

According to my Google Assistant app (Android), it’s 0.5.30#0.5.30.;

Is this the most up to date version? If not, how can I update my device? I didn’t see/couldn’t find a manual way to update the Bolt’s firmware through the Google Assistant app on my Moto X4.

Thanking the forum in advance.
