How to get the new release of ComponentSpace SAML V2 when we already bought it

Hi,
We paid ComponentSpace SAML V2 assembly.
I get the version 2.6.0.13 of the assembly after I bought it.

Now I want to upgrade our assembly and also know all releases notes since 2.6.0.13 and the last available version.

How it can be done ?

Thanks
