No. You can play an outdated version of the game for free at minecraft's website, but to play the full version, you (or someone else) must have had paid for it.
Simply go into 'edit profile' on the launcher and select which version you want to play in. This should solve the 'outdated client' issue.
Client outdated means that the client (the software used to connect to the server) is out of date. You need to update your version of Minecraft.
It usually means the server version is older then your game version. Every time Minecraft updates they usually update the server also.
Minecraft Classic is an outdated but free version of Minecraft. you have no health. unlimited blocks. Alpha terrain.
Update your minecraft.
you cant encounter him in any version in the game
It means the server is using an old version, older than the version you are using.
You can play the demo version or Minecraft Classic on the Minecraft website.
An outdated server is a server that is not up-to-date with the version you're playing on. For example, if you are on 1.8 and the server is on 1.7.9, it is considered outdated
Same as they are now. Except you push different buttons to take screenshots
Minecraft on the website are genuine. I play on a cracked version of Minecraft so i have it as an .exe
