Django 1.4.9 版本发行说明

Readdressed denial-of-service via password hashers

Django 1.4.8 imposes a 4096-byte limit on passwords in order to mitigate a denial-of-service attack through submission of bogus but extremely large passwords. In Django 1.4.9, we've reverted this change and instead improved the speed of our PBKDF2 algorithm by not rehashing the key on every iteration.
