UPGRADING FROM RT 4.2.0 and greater

The 4.4 release is a major upgrade and as such there are more changes than in a minor bugfix release (e.g., 4.2.2 to 4.2.3) and some of these changes are backward-incompatible. The following lists some of the notable changes, especially those that might require you to change a configuration option or other setting due to a change in RT. Read this section carefully before you upgrade and look for changes to features you currently use.

See devel/docs/UPGRADING-4.4 for internals changes relevant to extension writers.
