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:
22 * Patches that fix severe issues, like fixes for CVEs
24 * Patches that fix regressions
26 If you think the patch would be important for users of the current release
27 (or for a distribution picking fixes), it is usually a good candidate
31 How to get a patch into QEMU stable
32 -----------------------------------
34 There are various ways to get a patch into stable:
36 * Preferred: Make sure that the stable maintainers are on copy when you send
41 Cc: qemu-stable@nongnu.org
43 to the patch description. By default, this will send a copy of the patch
44 to ``qemu-stable@nongnu.org`` if you use git send-email, which is where
45 patches that are stable candidates are tracked by the maintainers.
47 * You can also reply to a patch and put ``qemu-stable@nongnu.org`` on copy
48 directly in your mail client if you think a previously submitted patch
49 should be considered for a stable release.
51 * If a maintainer judges the patch appropriate for stable later on (or you
52 notify them), they will add the same line to the patch, meaning that
53 the stable maintainers will be on copy on the maintainer's pull request.
55 * If you judge an already merged patch suitable for stable, send a mail
56 (preferably as a reply to the most recent patch submission) to
57 ``qemu-stable@nongnu.org`` along with ``qemu-devel@nongnu.org`` and
58 appropriate other people (like the patch author or the relevant maintainer)
61 Stable release process
62 ----------------------
64 When the stable maintainers prepare a new stable release, they will prepare
65 a git branch with a release candidate and send the patches out to
66 ``qemu-devel@nongnu.org`` for review. If any of your patches are included,
67 please verify that they look fine, especially if the maintainer had to tweak
68 the patch as part of back-porting things across branches. You may also
69 nominate other patches that you think are suitable for inclusion. After
70 review is complete (may involve more release candidates), a new stable release
