File talk:Usage share of web browsers that pass Acid2.png

I think it would be informative to include some kind of indication of points in time on this graph both of official release dates of browsers that pass Acid2, and dates that upgrades were made available to users from older versions that do not pass. The former are available in the article itself, and the latter should be in the specific articles for each browser. Mardeg (talk) 10:42, 30 April 2009 (UTC)
