Version Description Document
What it actually means
The document that accompanies a software release stating exactly what it is: version identifiers of every component, changes since the last release, resolved and open problem reports, and installation notes. It's the configuration management record that makes a software delivery auditable rather than a mystery zip file.
Where you'll meet it
Software releases on programs with formal CM, per MIL-STD-498 lineage.
