As of this writing, the current production version of Perl is 5.8.8 (which is Perl version 5 point 8, patch level 8).
You can download the code from http://www.perl.com and build it yourself from source. You will occasionally find updated versions in APT format for Ubuntu, which can be installed by updating your system. See Chapter 7, "Managing Software," to see how to quickly get a list of available updates for Ubuntu.
You can determine what version of Perl you installed by typing perl -v at a shell prompt. If you are installing the latest Ubuntu distribution, you should have the latest version of Perl.
