Microsoft and others use the term "release to manufacturing" (RTM) to refer
to this version (for commercial products, like Windows XP, as in, "Build 2600 is
the Windows XP RTM release"), and "release to Web" (RTW) for freely downloadable
products. Typically, RTM is weeks or months before General Availability (GA)
because the RTM version must be stamped to disc and boxed etc.
Box copy
A box copy is the final product, printed on a disc that is included in
the actual release, complete with disc graphic art. This term is used mostly by
reviewers to differentiate from gold master discs. A box copy does not
necessarily come enclosed in the actual boxed product - it refers to the disc
itself.
