Google put out its monthly list of algorithm changes today. There were 50 changes in all, though technically not every single one of them is related to the Google algorithm.
There was an interesting changes listed related to users' passwords. Google says:

Last month, Google expanded encrypted search as the default mode for signed in users on a worldwide basis.
