I have just upgraded myself to new version and started development in 9.0.1 Revision 20131022.0932 ( release 9.0.1). I have couple of small queries.
1) Am I using the right version for development or need to upgrade by implementing patches etc?. This is stable for development?
2) Previously I was developing applications on 8.5.2 but my clients were on 8.5.x and 9.x.
This migration is safe for existing applications? no crashes? no code mismatch? Is their any guideline for developer? Co-Existence of clients is possible?
Please guide me and thanks in advance
Best Regards, Qaiser
