This is a table of major Darwin releases with their dates of release and their corresponding Mac OS X releases. Note that the corresponding Mac OS X release may have been released on a different date; refer to the Mac OS X pages for those dates.

The jump in version numbers from Darwin 1.4.1 to 5.1 with the release of Mac OS X v10.1.1 was designed to tie Darwin to the Mac OS X version and build numbering system. In the build numbering system of Mac OS X, every version has a unique beginning build number, which identifies what whole version of Mac OS X it is part of. Mac OS X v10.0 had build numbers starting with 4, 10.1 had build numbers starting with 5, and so forth (earlier build numbers represented developer releases). The point release number in the Darwin version is always the same as the second point number in the Mac OS X version. In the case of Mac OS X v10.1.1 (the version where the jump in version numbers was made), this was build 5M28 and the 10.1.1 release, from which a version number of 5.1 was derived.
The command uname -r in Terminal will show the Darwin version number, and the command uname -v will show the XNU build version string, which includes the Darwin version number.

Famous quotes containing the words release and/or history:
“Come, thou long-expected Jesus,
born to set thy people free;
from our fears and sins release us,
let us find our rest in thee.”
—Charles Wesley (1707–1788)
“A poet’s object is not to tell what actually happened but what could or would happen either probably or inevitably.... For this reason poetry is something more scientific and serious than history, because poetry tends to give general truths while history gives particular facts.”
—Aristotle (384–323 B.C.)
