Yesterday I upgraded from 1.7.0 to the latest 1.7.1. The build I downloaded was labeled 20110520 in my EE download account. I followed the upgrade instructions to the letter (and I was starting with 1.7.0, as I said).
I just noticed that the back-end pages of the site are displaying this in the footer:
ExpressionEngine 1.7.1 - © Copyright 2003 - 2011 - EllisLab, Inc.
Script executed in 1.1813 seconds 28 SQL queries used
Build: 20101018
Is that incorrect build number merely a cosmetic oversight, or did something go wrong with my upgrade? (I have never downloaded any other build of 1.7.1 except the one labeled 20110520.)
