If you want to know which version of Minecraft
is the most up-to-date version available,
open the Minecraft launcher.
Click the menu on the bottom left.
Here, you will see an option
that displays the latest version of Minecraft.
You can select this option,
then click the green play button
to launch the latest version of the game.
Snapshots are versions of Minecraft
that are in a testing phase,
allowing players to try out new features.
If you would like to play
the latest snapshot of the game,
click on "Installations."
Click the snapshots option on the right.
This allows you to play both
the latest-release versions and development versions
by switching profiles on the launcher.
Go back to the main page on the launcher
by clicking "Play,"
and from the menu on the bottom left,
select the latest snapshot.
Then click the green play button
to launch the latest snapshot version of the game.
