maxscale-2.5.11 tarball: dir var is missing

Hi,
according to installation guide using a tarball there's a step to modify directory var:

$ sudo groupadd maxscale

$ sudo useradd -g maxscale maxscale

$ cd /usr/local

$ sudo tar -xzvf maxscale-x.y.z.OS.tar.gz

$ sudo ln -s maxscale-x.y.z.OS maxscale

$ cd maxscale

$ sudo chown -R maxscale var

However there's no directory var in the tarball.

This means I have downloaded a wrong tarball.

Can you please advise where to download tarball maxscale-2.5.11.OS.tar.gz?
