As far as I am aware, the following patches submitted before July 1st are still "open":
http://spring.clan-sy.com/mantis/view.php?id=525 (shouldn't be committed at all, in current state)
http://spring.clan-sy.com/mantis/view.php?id=528 (only the second patch)
http://spring.clan-sy.com/mantis/view.php?id=553 (I'm looking at this one)
None of them are release blocking if they are not committed.
Other patches that add features will have to wait till after the release. Of course patches that fix bugs can be applied no matter what

Also it should be obvious that I'd also like it if you didn't commit code that has a high chance to cause regressions next few days. Things that are still open and bugfixes are all fine; I trust anyone with commit access to know what they are doing

EDIT: updated patch list
