[quote author="Dam1an" date="1251827958"]Derek has conveniently written a post about getting the latest version from the SVN which should guide you through the process and saves me basically repeating him

If you get stuck with that, just post back here[/quote]

Hello. That post is very old ..5 years old. I can't update codeigniter directory using this link : “http://dev.ellislab.com/svn/CodeIgniter/trunk”

Which link I need to use these days?

Any helpful information is highly appreciated!
