Tiki10
Tiki10 is planned for October 2012.Since it's just after Tiki9 LTS, it's expected to be a big release. See Roadmap and Tiki10
Since PHP 5.2 started in November 2006 and PHP 5.2.x reached end of life in December 2010, which is nearly two years before Tiki10 will be released, the requirements will be PHP 5.3.x
If you require pre-5.3 support, you can use Tiki9 which is a Long Term Support version.

Kaltura support has been revamped to be much easier to setup.PHPIDS - Intrusion Detection System
"PHPIDS (PHP-Intrusion Detection System) is a simple to use, well structured, fast and state-of-the-art security layer for your PHP based web application. The IDS neither strips, sanitizes nor filters any malicious input, it simply recognizes when an attacker tries to break your site and reacts in exactly the way you want it to. Based on a set of approved and heavily tested filter rules any attack is given a numerical impact rating which makes it easy to decide what kind of action should follow the hacking attempt. This could range from simple logging to sending out an emergency mail to the development team, displaying a warning message for the attacker or even ending the user’s session.PHPIDS enables you to see who’s attacking your site and how and all without the tedious trawling of logfiles or searching hacker forums for your domain. Last but not least it’s licensed under the LGPL!"
