| Release Cycle |
| ============= |
| |
| The U-Boot projects attempts to maintain a fixed, predictable Release |
| Cycle as follows: |
| |
| * We will have U-Boot releases at a fixed release interval of (approximately) |
| every 3 months. |
| |
| * Under normal conditions the release date will be the first Monday of the month. |
| |
| * Immediately following each release, there will be a "merge window" of |
| normally 21 days, i. e. if the release was on a Monday, then the merge window |
| will close on the Monday in the 3rd week after the release. |
| |
| While this merge window is open, new features can be added to the U-Boot |
| source tree. This is further expanded on in the :doc:`process`. |
| |
| * After the merge window closes, no new features may be added to allow for a |
| release candidate phase which is intended to fix bugs and regressions. |
| |
| *Note:* While we try to adhere to the release schedule, we will |
| not hesitate and take the liberty to delay a release if there are |
| good reasons, for example if there are known bugs or other technical |
| reasons. The code will be released when it is considered ready |
| without caring too much about the announced deadline. |
| |
| *Note 2:* Even though we follow Linux ways in many respects, there are |
| differences in the actual procedures, which are documented in the |
| :doc:`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 calendar year and month of the release date. Additional fields are |
| frequently used to denote the release candidates. They are also used on rare |
| occasions to note a bug fix release on top of the previous stable release. |
| |
| Examples:: |
| |
| U-Boot v2009.11 - Release November 2009 |
| U-Boot v2009.11.1 - Bug fix release 1 on top of the November 2009 release |
| U-Boot v2010.09-rc1 - Release candidate 1 for September 2010 release |
| |
