Google has published the new and official Android 8.1.0 firmware version with build date set for February 2018.
Check the info in this post if you wish to complete the new update process manually before the official OTA files are rolled out in your region.

This guide has to be used only for the Unlocked International Google Pixel 2 XL devices.
Do not attempt to update other different Pixel models with the files found in this post.

If you've modified the installed ROM in any way, then you should know that the update cannot be applied over custom or modified ROMs.
You need to enable USB Debugging and OEM Unlock from Developer Options.
If you can't find Developer Options you need to enable these first: go to Settings> About Phone and tap seven times on the Firmware Build Number text. Return to Settings, find Developer Options and enable both USB Debugging and OEM Unlock.
