I haven't seen it mentioned, so I'll just highlight that in the quickplay rules it mentions that free actions can now occur ANYTIME, even when its not your turn!!
It doesn't really make a big difference with 3e.
In 3e we get as many free actions as we want on our round, plus a bunch of other actions (unnamed in 3.0, "immediate" in 3.5) which could be done on someone else's round.
In 4e we get one group only, uniformed to immediate actions. However some of former free actions will turn into minor actions.
3.5 swift actions are basically just bundled to 4e minor actions.
Summary:
(3e)
actions you can do once in your turn
actions you can do as many times in your turn
actions you can do as many times anytime
(4e)
actions you can do once in your turn
actions you can do as many times in your turn
actions you can do as many times anytime
But then the difference is not that big IMHO, perhaps most of those "type 2" actions weren't usually worth taking more than once per round.
Really depends on which actions go under each type. For instance, if you could stand up from prone as a free action (by some special ability) in 3e, this will necessarily go under Minor actions in 4e. If someone can drop you more than once during YOUR turn, you won't be able to get up a second time.
I hope that only a few actions will be 4e free actions. Occasionally interrupting someone else's turn makes for an interesting battle, BUT too many possible interruptions will certainly turn it into a nightmare.
