- It is a bad idea to run different versions of Isis with each other. This
- applies to all the Isis servers (protos, isis, rexec, etc.) and the
- application libraries (libisis1.a libisis2.a libisism.a). That's the safest
- piece of advice.
-
- We actually have compatibility checking code in the message library that,
- whenever a message is received from any other Isis process (server of
- applcation process), checks that the sending process has a compatible version
- of Isis. Recently we discovered that this checking code isn't restrictive
- enough. (It compares only the major and minor version numbers, not the dot
- and patch versions, and we made an incompatible change to some internal
- protoco between V3.0.5 and V3.0.6). We are fixing this code for future
- releases, but the best advice is not to run different processes compiled
- against different versions of Isis.
