Terracotta and Concrete blocks update?

Hi all~
Just been having a look at mc related stuffage and noticed a 1.12 update that adds some really interesting and wacky blocks - terracotta and concrete. Any chance these cpuld be updated to the server at all? Just wondering.

1.12 isn’t fully out yet. When it’s properly released we’ll need to wait for Spigot and plugins to update, which could take a couple of months.

Yea, I think 1.12 is still in testing?
