Compiling is not a big deal, it's just a few buttons to hit.
What takes most of the time is updating the website, increasing the version number everywhere it appears, making sure that every tutorial is up-to-date, synchronizing with external contributors for ports and bindings, uploading the 200 Mb of archives, making annoucements, ... This kind of stuff can hardly be automated
But don't worry, in the future there will be more releases. Starting with SFML 2.0, the API will have a stable interface, and I'll be able to release minor versions (bug fixes) that don't require all the steps of a major release.
Laurent, a suggestion for building software packages with ease is using some kind of automated build environment, like BuildBot, or a set of cross compilers.
From what I've seen, BuildBot is a tool for automating compiling and unit tests, not for creating distributable packages.
Btw, do you need someone building SFML for Linux 64 Bit?
Absolutely
