[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.

I'd maybe drop the "2018" here, and use a three digit version number
(since you describe the three digits below) ... maybe rather write it
like this:

 Since version 3.0.0, QEMU uses a time based version numbering scheme:
