oracle 6.0.34 vs 6.0.37

Can anyone tell me of any significant changes from 6.0.34 to 6.0.37 We are getting ready to bring up 7.? under SCO but still need a version 6 setup. All of our other databases are running 6.0.34 so we would probably make the last one 6.0.34 also unless there is a good reason to use 6.0.37 (are forms and reports compatible across the two versions?) Is it any easier to migrate to version 7 from 6.0.37?

Thanks for any help,
