Hello all,

Is there any documentation available discussing backwards compatibility of 2.5.0p2? I am testing a new amanda backup server. The old server had 2.4.5p1 and the new server has 2.5.0p2. I have various versions of the client on my backup targets. Some of these are rather hard to upgrade at this point because of legacy OSes. I have the following clients: 2.4.3, 2.4.4p1, 2.4.4p2, 2.4.4p4, 2.4.5, 2.4.5p1, 2.5.0p2, 2.5.2. All of these clients worked reliably with the 2.4.5p1 server. Under the test 2.5.0p2 server, with the same config as the older server, I get the following errors:

2.4.3 fails the client check with a timeout waiting for ACK
2.4.4p1 and 2.4.4p2 fail with "hmm, disk was stranded on waitq"

One 2.5.0p2 client and the only 2.5.2 client both had estimate timeouts (may be unrelated)

On the other hand, 2.4.4p4, 2.4.5, 2.4.5p1, and the other 2.5.0p2 clients all worked.

I'm just curious if these are known incompatibilities or something specific to my setup I need to look into further.
