From the InfoQ article yesterday: "Although posted on April 1, the switch is not an April fool." (http://www.infoq.com/news/2014/04/svn-migrates-to-git)

The whole thing was clever, but I'm not sure it counts as as being "fooled" when the gag specifically denies being a gag. I'm not sure I like this precedent (and I love April Fools jokes in general).

But maybe the article from yesterday was a third-party source who had fallen for it? If that's the case, then well-played. :)
