1 QEMU and the stable process
2 ===========================
7 QEMU stable releases are based upon the last released QEMU version
8 and marked by an additional version number, e.g. 2.10.1. Occasionally,
9 a four-number version is released, if a single urgent fix needs to go
12 Usually, stable releases are only provided for the last major QEMU
13 release. For example, when QEMU 2.11.0 is released, 2.11.x or 2.11.x.y
14 stable releases are produced only until QEMU 2.12.0 is released, at
15 which point the stable process moves to producing 2.12.x/2.12.x.y releases.
17 What should go into a stable release?
18 -------------------------------------
20 Generally, the following patches are considered stable material:
21 - Patches that fix severe issues, like fixes for CVEs
22 - Patches that fix regressions
24 If you think the patch would be important for users of the current release
25 (or for a distribution picking fixes), it is usually a good candidate
29 How to get a patch into QEMU stable
30 -----------------------------------
32 There are various ways to get a patch into stable:
34 * Preferred: Make sure that the stable maintainers are on copy when you send
39 Cc: qemu-stable@nongnu.org
41 to the patch description. By default, this will send a copy of the patch
42 to ``qemu-stable@nongnu.org`` if you use git send-email, which is where
43 patches that are stable candidates are tracked by the maintainers.
45 * You can also reply to a patch and put ``qemu-stable@nongnu.org`` on copy
46 directly in your mail client if you think a previously submitted patch
47 should be considered for a stable release.
49 * If a maintainer judges the patch appropriate for stable later on (or you
50 notify them), they will add the same line to the patch, meaning that
51 the stable maintainers will be on copy on the maintainer's pull request.
53 * If you judge an already merged patch suitable for stable, send a mail
54 (preferably as a reply to the most recent patch submission) to
55 ``qemu-stable@nongnu.org`` along with ``qemu-devel@nongnu.org`` and
56 appropriate other people (like the patch author or the relevant maintainer)
59 Stable release process
60 ----------------------
62 When the stable maintainers prepare a new stable release, they will prepare
63 a git branch with a release candidate and send the patches out to
64 ``qemu-devel@nongnu.org`` for review. If any of your patches are included,
65 please verify that they look fine, especially if the maintainer had to tweak
66 the patch as part of back-porting things across branches. You may also
67 nominate other patches that you think are suitable for inclusion. After
68 review is complete (may involve more release candidates), a new stable release
