How to update tikz-cd (TexLive)?

Question

My tikz-cd is out-of-date.

I have found this version which seems the latest: http://pgf.sourceforge.net/

Then I unzip the package, put the "pgf" from the package to my ~/texmf directory.

But I don't know what to do to get my latex system to use the new version instead of the old version.

Any ideas?

I finally found the solution:

First I need to upgrade to TexLive 2015, using the script that can be downloaded.

Then:

sudo tlmgr install pgf

sudo tlmgr install tikz-cd
