Why did god's value system change between the Old and New Testaments?

In the Old Testament, god was more than willing to intervene in the affairs of man. Despite giving us free will, the Bible clearly shows how god would step in and set things straight. Then, apparently, something happened and god decided a hands-off approach would be better.

Now, most people would look at behavior like this and say "god changed his mind", or "learned from his mistakes", but that would imply that god wasn't perfect. Others would say mankind matured to the point where god didn't find it necessary to intervene directly anymore. He just does things subtly now (tsunamis, cancer remission, bleeding statues) and leaves us to interpret the "divineness" of these events.

Nevertheless, the starkness of god's personality shift is plainly apparent to anyone who reads the Bible, and it begs the question, WHY would god ever change how he does things at all if he is eternal, all-knowing, and perfect?
