PHP 5.3.3 is Coming

PHP 5.3.2 was released back in March 2010, so it was about four months ago and right now, the current development for the next PHP 5.3.3 has come to RC2. I believe that the final version should be released at worst next month if there aren't too much problem with the current development tree.

I wonder what big changes will they introduce in the next 5.3.3 release?
