In the Magical World of Continuous Deployments, it'll usually point to
the second-to-most-recent version -- not the version currently being
deployed but the last version that was completely rolled out
(technical detail: it indirectly uses the /home/wikipedia/php symlink,
which currently points to php-1.19). So right now that's 1.19, even
though some wikis are already on 1.20wmf1. Version-specific skin URLs
such as skins-1.18 and skins-1.19 WILL BREAK once the version in
question is no longer live on any wiki and we're getting ready to
deploy the next one. So skins-1.18 is gone now, and once we start the
1.20wmf2 roll-out, skins-1.19 will be removed and skins/ will be
updated to point to 1.20wmf1. There are always at most two versions on
the cluster at any given time; we can't have more due to APC cache
size issues.
