Connecting a 10.1C client to 10.1A database

I've just tried connecting a 10.1C client to a 10.1A database and it appears to work fine.
However I was hoping I could find some definite info about backwards compatibility and if Progress will support it. Is this information available? I'm also curious about using a 10.2A client on a 10.1A database.
 
Clients can connect up to 1 major release backwards. So a version 10 (any point release) client can connect backwards to any version 9 database.

At this point clients cannot connect forward major releases. Connecting forward within a major release (i.e. 10.0a client, 10.1c server) generally works but you won't be able to leverage new features that the client doesn't know about. A 10.0 client, for instance, knows nothing about 64 bit integers. This might cause a problem in a mixed environment if a more advanced client does something to the data that an older client will barf on.

App servers can also be used connect any client to any db server. Obviously the warning about using new features applies.
