[1.5.x] Added 1.5.5 and 1.4.9 release notes

==========================

Django 1.4.9 release notes

==========================

*October 22, 2013*

Django 1.4.9 fixes a security-related bug in the 1.4 series and one other

data corruption bug.

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 1.5.5, we've reverted this change and instead improved

the speed of our PBKDF2 algorithm by not rehashing the key on every iteration.

Bugfixes

========

* Fixed a data corruption bug with ``datetime_safe.datetime.combine`` (#21256).

Django 1.5.5 release notes

==========================

*October 22, 2013*

Django 1.5.5 fixes a couple security-related bugs and several other bugs in the

1.5 series.

Readdressed denial-of-service via password hashers

--------------------------------------------------

Django 1.5.4 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 1.5.5, we've reverted this change and instead improved

the speed of our PBKDF2 algorithm by not rehashing the key on every iteration.

Properly rotate CSRF token on login

-----------------------------------

This behavior introduced as a security hardening measure in Django 1.5.2 did

not work properly and is now fixed.
