In the case of MeshCentral v0.4.6-d, it was there for a few hours and I had to pull it because it had a bad issue. Once you put a version online, NPM does not allow you to reuse that version number so, it gets skipped. This said, I probably accidentally double bumped up the version number a few times in the past, causing a skip 
In real news, I updated the public server, https://meshcentral.com last night to the very latest version. A lot of people use that server and it's sometimes months behind as I want to keep it stable. MeshCentral.com now requires that the privacy bar show up on the remote system when you do a remote desktop session, this is only hard coded for this specific server. You can still do remote desktop without the privacy bar when setting up your own server.
