U-Boot Release Cycle

Like with many other things, U-Boot development follows the Linux model of a release cycle. That means:

ALERT! Note: even though we follow Linux ways in may respects, there are differences in the actual procedures, which are documented in section "Development Process".

Version Numbers:

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 now identified by names consisting of the calender year and month of the release date. Additional fields (if present) indicate release candidates or bug fix releases in "stable" maintenance trees.


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
