   1 Release Cycle
   2 =============
   3
   4 The U-Boot projects attempts to maintain a fixed, predictable Release
   5 Cycle as follows:
   6
   7 * We will have U-Boot releases at a fixed release interval of (approximately)
   8   every 3 months.
   9
  10 * Under normal conditions the release date will be the first Monday of the month.
  11
  12 * Immediately following each release, there will be a "merge window" of
  13   normally 21 days, i. e. if the release was on a Monday, then the merge window
  14   will close on the Monday in the 3rd week after the release.
  15
  16   While this merge window is open, new features can be added to the U-Boot
  17   source tree. This is further expanded on in the :doc:`process`.
  18
  19 * After the merge window closes, no new features may be added to allow for a
  20   release candidate phase which is intended to fix bugs and regressions.
  21
  22 *Note:* While we try to adhere to the release schedule, we will
  23 not hesitate and take the liberty to delay a release if there are
  24 good reasons, for example if there are known bugs or other technical
  25 reasons.  The code will be released when it is considered ready
  26 without caring too much about the announced deadline.
  27
  28 *Note 2:* Even though we follow Linux ways in many respects, there are
  29 differences in the actual procedures, which are documented in the
  30 :doc:`process`.

  32 Version Numbers
  33 ---------------
  34
  35 Starting with the release in October 2008, the names of the releases were
  36 changed from numerical release numbers without deeper meaning into a time stamp
  37 based numbering.  Regular releases are now identified by names consisting of
  38 the calendar year and month of the release date.  Additional fields are
  39 frequently used to denote the release candidates.  They are also used on rare
  40 occasions to note a bug fix release on top of the previous stable release.
  41
  42 Examples::
  43
  44   U-Boot v2009.11       - Release November 2009
  45   U-Boot v2009.11.1     - Bug fix release 1 on top of the November 2009 release
  46   U-Boot v2010.09-rc1   - Release candidate 1 for September 2010 release
