what are the basic differences between webMethods 9.0 and 9.5 version?
-TLS 1.1 & 1.2 supported for SSLV3
-EDI version is updated to 9.0
-Support for subversion 1.8
-Cloud stream support
and lot more features, I suggest to go through SAG webnairs frequently
I would recommend you to go through the readme and the release notes. You will come to know what is newly being added/updated/deprecated.
