As you may already know, Minecraft 1.8 is scheduled to be released tomorrow. You can review the changes and new features in the update here.
We expect to update the network within a day after 1.8 is released, but we would recommend editing your profile to change your Minecraft version to 1.7.10 instead of the latest version to ensure that you have no problems connecting to CSG before it's updated.
We tested the builds compatible with the 1.8 client on our test server. Everything seems to be working fine except for the plugin for pets - so the pets may be missing for a few days after the update. Don't worry, the DB is not going anywhere, and your pets will join you as soon as the plugin gets updated.
