The current release is always available from the Download section of our web site.
Private builds are posted on the Forum and Twitter.
When you launch a AIR SinangeStudio and a new version is available, you will be promoted to upgrade.
When launching the WEB Studio, you are always running the latest version.
When it comes the the AIRPlayer, when you enter the "Stations" section of the Studio, you may be prompted to that a new version is available. You can select to update ALL, or cancel out of it.
If you have many players installed, you may want to cancel out, and upgrade each Player individually using the "Check for new version" Icon under "Stations" (with the MediaSignage Logo).
We go to great lengths to make sure each GA (general availability) release is stable.
However it's always a good idea to upgrade the Players one at a time, checking that everything is working well for you.
When you launch the WebPlayer, you are always running the latest release.
Hope this help,

It is normally safe and recommended that you run the latest Studio software.
