Upgrade vs. Update - Which do you choose?

ExtendSim 9The difference between a software upgrade and a software update can be confusing.

A software upgrade is a newer, more fully-featured version of your current software. Upgrades are offered at a reduced price or are included with Maintenance Plans. Upgrades are denoted by a change in release number; e.g. ExtendSim 9 is an upgrade to ExtendSim 8.

A software update improves the quality and stability of a release through software enhancements and bug fixes. Updates are made available by free download. An update will append a release number with ".x.x".
