As per https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-tds/60f56408-0188-4cd5-8b90-25c6f2423868 there seems to be no constraint on the TDS-Version.
As I understand the documentation, the parameter is used for the client to communicate its thread-id for debugging-purposes. If sent by the server, it should be empty in any case.

I'm not sure about the code-style. I did not want to copy the whole readTypeInfo func for v7.1 compatibility as the version-info is needed in readVarLen

There still seems to be a problem with the transactions. |
