What is SwOS 2.13p?

[bp0]

On CRS305 with SwOS, the upgrade tab shows that it is running 2.13p which is one second newer than 2.13, the “latest available version”. Also, it says a new version is available for upgrade and has a button to “Download & Upgrade”. How is 2.13p different from 2.13? Will clicking the button install 2.13?

Here is a screenshot:

It is SwOS’s primary version, or you can also call it a backup SwOS version. The primary version feature set is identical to the non-primary version, but we recommend using the non-primary one.
