Where can I find which FOS Versions are compatible with each othere within a fabric?
I have an old switch with FOS 6.4.3b and want to know when I add a new swtich into the fabric, which is the latest FOS Version I can use.

The release note of the highest FOS will provide you the compatibility guidance around that.

Which means I have to read sequentially through all the Release Notes until I find one that isn't compatible?
Wouldn't it be helpful if this information was held in a central table somewhere? It would only then need to be extended by each release.

In the release notes, there is a high level of details about all the product types and FOS versions supported.
The section where you have to look at is: Fabric OS Compatibility
If you want to add a new swicth in an existing fabric, check what is the minimum and maximum level of FOS required for both old and new switch and check if you can find a commun FOS release or by default a compatible one between old and new switch.
What is the product type of your old switch?
What is the product type of your new switch?

So, 5100 is 8G capable with a mawimum of FOS 7.X, 6505 is 16G capable with a minimum of FOS 7.x.
Latest Target Path for FOS 7 is FOS 7.4.2a.
7.4.2a release note (check page 25)

Sorry, I'm not really sure if this answered my question, since I don't want to update the FOS of the 5100 (at least not disruptively).
Does this mean I can operate the 5100 with FOS 6.4.3b with a 6505 with 7.4.2a.within the same fabric (even if for only a short time while migrating the ports from the 5100 to the 6505 ) ?

Yes you can run 5100 in 6.4.3b with 6505 at 7.4.2a.
See release note of 7.4.2a page 29.
