 Versioning:
 ===========
 
-U-Boot uses a 3 level version number containing a version, a
-sub-version, and a patchlevel: "U-Boot-2.34.5" means version "2",
-sub-version "34", and patchlevel "4".
-
-The patchlevel is used to indicate certain stages of development
-between released versions, i. e. officially released versions of
-U-Boot will always have a patchlevel of "0".
+Starting with the release in October 2008, the names of the releases
+were changed from numerical release numbers without deeper meaning
+into a time stamp based numbering. Regular releases are identified by
+names consisting of the calendar year and month of the release date.
+Additional fields (if present) indicate release candidates or bug fix
+releases in "stable" maintenance trees.
+
+Examples:
+       U-Boot v2009.11     - Release November 2009
+       U-Boot v2009.11.1   - Release 1 in version November 2009 stable tree
+       U-Boot v2010.09-rc1 - Release candiate 1 for September 2010 release
