AsteriskNOW 1.5.0, which launched as a beta in October 2008, is now available for download at http://www.asterisknow.org/downloads. Of course, existing AsteriskNOW users can simply run "yum update" to update to the latest release. I love 'yum' for Linux systems - it's like Windows Update on steroids, but without the Internet Explorer GUI requirement. 
According to AsteriskNOW, here are the notable changes since beta2:
* Updated several packages to latest versions (Asterisk, DAHDI, etc)
* Fixed more permissions issues between Asterisk and httpd/FreePBX.
* Updated to CentOS 5.3 (http://lists.centos.org/pipermail/centos-announce/2009-April/015711.html)
