FreeBSD is under constant development between releases. Some people prefer to use the officially released versions, while others prefer to keep in sync with the latest developments. However, even official releases are often updated with security and other critical fixes. Regardless of the version used, FreeBSD provides all necessary tools to keep your system updated, and also allows for easy upgrades between versions. This chapter will help you decide if you want to track the development system, or stick with one of the released versions. The basic tools for keeping your system up to date are also presented.
