Google's Matt Cutts provides an update to a "deliberate" algorithmic change in Google search that influences long-tail searches more than others. Cutts says it focuses on "quality." It has nothing to do with Caffeine, though the process of speeding up the Web did influence the decision to tweak the algorithm.

The permanent change influences Google's algorithms that assess the sites that best match long-tail queries. Some of the posts around the Web refer to the change as "Mayday." Cutts says Google makes more than 400 quality algorithm changes to search per year.
