Mintest 0.4.5 was released some time ago, for any one that has had trouble compiling it I found this on the minetest forum and found it to be quite nice when upgrading to the latest development version.
For Ubuntu Users:
copy and past this intire one liner into the terminal, enter the sudo password, it will install the needed packages download the source, compile it, and start the game all in one shot.
then when you want to play just use this command to start it again.
sudo apt-get install git-core build-essential libirrlicht-dev libgettextpo0 libfreetype6-dev cmake libbz2-dev libpng12-dev libjpeg8-dev libxxf86vm-dev libgl1-mesa-dev libsqlite3-dev libogg-dev libvorbis-dev libopenal-dev; git clone git://github.com/minetest/minetest.git;cd minetest/games; git clone git://github.com/minetest/minetest_game.git; git clone git://github.com/minetest/common.git; cd ..; cmake . -DENABLE_GETTEXT=1 -DENABLE_FREETYPE=1; cd src; make -j2; cd ../bin; ./minetest; echo -e "\n\nYou can run Minetest again by double-clicking \"minetest\" in the \"bin\" folder of the \"minetest\" folder in your home folder.\nYou can install mods in ~/.minetest/mods/minetest, too."
if you want to run a server
I have also created a bitcoin mod for the game, no not real bitcoins but a bitcoin like theme to the game. now you are actually mining for bitcoins in the game, again not real Bitcoins, but a bitcoin theme / novelty item
