[Qemu-devel] [qemu-web PATCH] download: document version numbering scheme

[Daniel P . Berrangé]

The new version numbering scheme was mentioned in the blog post
announcing 3.0 previously, but this will fall out of view over
time. It is thus preferrable to mention this on the download page
too.

+<h2>Version numbering</h2>
+<div>
+  <p>
+  In 2018, for the QEMU 3.0 release, a time based version numbering scheme was
+  adopted:
+  </p>
+<ul>
+<dt>major</dt>
+<dd>incremented by 1 for the first release of the year</dd>
+<dt>minor</dt>
+<dd>reset to 0 with every major increment, otherwise incremented by 1 for each 
release from git master</dd>
+<dt>micro</dt>
+<dd>always 0 for releases from git master, incremented by 1 for each stable 
branch release</dd>
+</ul>
+  <p>
+    The implication of this is that changes in major version number
+    <strong>do not</strong> have any bearing on the scope of changes
+    included in the release. Non-backward compatible changes may be made
+    in any master branch release, provided they have followed the
+    <a 
href="https://qemu.weilnetz.de/doc/qemu-doc.html#Deprecated-features";>deprecation
 policy</a>
+    which calls for warnings to be emitted for a minimum of two releases
+    prior to the change.
+  </p>
+</div>
