GitLab 10.8.0-ce.0 Update Query

I am attempting to update a standard Omnibus version of GitLab 10.8.0, installed on Ubuntu 18.04.
#sudo apt-get update
#sudo apt-get install gitlab-ce

The output is
Reading package lists… Done
Building dependency tree
Reading state information… Done
gitlab-ce is already the newest version (10.8.0-ce.0).
The following packages were automatically installed and are no longer required:
libgnutls-openssl27 liblockfile-bin liblockfile1
Use ‘sudo apt autoremove’ to remove them.
0 to upgrade, 0 to newly install, 0 to remove and 2 not to upgrade.

This page would suggest that 10.8.0 is not the latest version
