openSSH versions

[Roee Agami]

Hi,

I notice here:
https://www.openssh.com/releasenotes.html

That the versions always have a <number> and a <number>p1.
Does the p1 indicate a patch? So does it mean that <number> and <number>p1 are two different versions?
It doesn’t describe the differences between the two in case they are different versions.

I would appreciate some clarification.

Thanks,
Roee.
