Just got the 8.1 OTA, why is the build number different?

[Android Central Question]

Hey guys, using a Pixel 2 from TELUS here in Canada. Just received the 8.1 OTA tonight but can't figure out why the build number is different.

Currently showing as OPM2.171019.012

Any guesses? And more importantly, will this fix my LTE reboot issues?

I just received that version today, after I had initially sideloaded the original 8.1 release last week. The original version broke cellular data on my Pixel 2...the latest seems to have fixed it.
