Saltation

Saltation is the exercise of updating a project's dependencies to the current published versions. New versions of dependencies typically offer new features, deprecate and remove old features, fix bugs and change functionality. Saltation is jerky and allows a period of time between code being changed and the effects of the change being noticed. Saltation is the antithesis of Continuous Integration within which current snapshot builds of all dependencies are used.
