FreeBSD: The Power to Serve
FreeBSD Release Model
FreeBSD releases maintained using CVS branches
Head of the tree (-current) will become FreeBSD 5.0
Last major release (4.0) was branched (-stable)
Subsequent minor releases (4.1, 4.2, etc) consist of bug fixes
backported from -current, and new features in -current that
have been extensively tested
Everyone has complete access to the source code at all times,
so incremental releases are not a "Flag day"
