With the 1.6 update just being released a lot of the players don't know how too downgrade too 1.6.4.
You should start with a screen like this.

Then go down too where it has this little part, and click edit profile.

You should then get this pop up.

Click onto the part where it says version, simply click it and scroll down until you find, 1.6.4.
It should look like this.

Then when the server has been updated simply just click version of 1.7.2
And then your done.

 

Oh I was on 1.7.2 I was wondering were to get to 1.6.4 this really helped.

 

Thx Kron :P

You're making people read all that when they can just read this:

Open client > Edit Profile > Use version: 'release 1.6.4' > Save profile.
