"//bits.wikimedia.org/skins/{monobook/main.css}" is setup to
always point to the latest version so that should be alright, but
someone else will need to confirm.
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.
