QGIS Visual Changelog makes learning about new features a breeze!

Many open source GIS programs have a roadmap, 'wiki', or version log. These exhaustive sources of information can give you the heads-up on when an update will be released and what features the new version may contain.  They also contain lists of bugs, potential fixes, and the progress toward the fix.

Lastly, updates for paid software are also important and sometimes may require you to update your license agreement, depending on when you purchased the software. Additional fees may apply.
