FOSS gamedev and creative worlds

please may someone share me the link of 4.4 cause i cannot find it thank you.

It's not officially released yet; you have to either compile, or, if you're on windows, you can use one of Sfan5's windows builds. You need 7zip to extract Sfan5's builds.

Direct link to Sfan5's build of 0.4.4: http://sfan.sf.funpic.de/minetest-builds/c55/minetest-0.4.4-655bb52-win32.7z

This one is the current git master (at least as I see it here this evening):
