An unconfirmed Google update has said to be missed. It occurred on June 27th/28th, with one also having taken place on 5th July.
Two different threads on Web master World discuss about both updates, which consists of the updates that took place on the following dates (above).
Not much gossip is going around about these updates, but the discussions seem to include it all. This may be related to the manual actions, even though many say there are no manual actions in Google Webmaster Tools.
Due to the fact there was not much chatter, shows the algorithm change was not so big.
