The latest stable release of Apache Traffic Server is 3.2.0 (released on 2012-06-19). 
Following the [Apache HTTPD](http://httpd.apache.org/) model, stable Apache 
Traffic Server releases will be numbered with an even first decimal (e.g. 2.0, 
3.12, etc), while unstable, developer focused releases will be numbered with 
an odd first number (e.g. 2.1, 3.21, etc). The second decimal will be used 
for releases containing bug fixes.

When downloading from a mirror, please be sure to verify the checksums and OpenPGP
compatible signature. You can also
