18.104.22.168 release notes
Post date: Mar 26, 2018 2:27:39 PM
Issue 938 - Made the metadata container name (more) unique by including not just the connection name but also the username and hostname. If you've seen deployments fail while in a QUEUED state when working in a shared org, this should likely resolve the issue for you
Fixed an issue that could cause custom Apex classes to be omitted from the OST in orgs with large numbers of custom classes. If you've experienced this issue, please regenerate your OST after taking this build.
