56 <h1>Linux stable releases</h1>
59 Linus releases a stable 3.<var>x</var> every 2-3 months after
60 a series of release candidates
63 Greg K-H maintains a <dfn>stable branch</dfn> for each Linus
64 release, with <dfn>stable update</dfn> releases numbered
65 3.<var>x</var>.<var>y</var>
68 Branch includes cherry-picked or backported changes to fix
69 serious bugs and add support for new devices
72 Updates released roughly every 1-2 weeks, at least until
73 3.<var>x</var>+1 is available
76 A <dfn>longterm</dfn> stable branch may be maintained by Greg or
77 another developer beyond this period
83 <h1>The stable update process (1)</h1>
86 All changes go to mailing
87 list <a href="mailto:stable@vger.kernel.org">stable@vger.kernel.org</a>
90 A commit with a <tt>Cc:</tt> pseudo-header for this address will
91 be picked up by stable maintainers once Linus pulls the commit
94 If it doesn't apply to a stable branch, the author is usually
95 notified and may provide a backported version
98 Any commit in Linus's tree, or a fix for a stable-only
99 regression, can be nominated by mail to this list, if it
100 meets the criteria - see
101 <a href="http://www.kernel.org/doc/Documentation/stable_kernel_rules.txt"><tt>Documentation/stable_kernel_rules.txt</tt></a>
