When you run ./release.sh, it'll attempt to push the security branch uncondtionally.
However, when producing a 'weekly' for that week (usually thursday before the weekend packaging), we only update the version.php on the supported branches. (Thats what ./prerelease.sh does by default)
If you then later run release.sh, it'll push the security release without version increment.
a) Stop release.sh pushing the security release without version increemnt
b) Decide on the 'week of point release' process and document it better (it's always confusing to me if we produce the weekly, and for what branches, etc)
