What's up with browser history entries?

Has there been some development going on recently with what gets saved in the browser history? I use Safari 7.0.4 on Mavericks and until quite recently every single post I looked at left an entry in Safari’s history file. It seems that now only certain posts get entered and I haven’t figured out yet what is going on.

Don’t get me wrong. I think it’s great that history is no longer needlessly filling up with a lot of stuff that lessens it’s usability.

I’m just trying to find out if I’m noticing something that was changed in discourse or if something mysterious is going on. If it is a deliberate change, can someone state the criteria for deciding if a history entry is made?

No change on our end. Would have to be a change in the browser.
