We are considering using API Gateway in a implementation but saw in documentation it is not supported in RH 6.8.
In documentation for API 9.1 we have 6.0-6.7 or even 7.2.
As we are using 6.8, would like to verify if the fact it only lists 6.7 because 6.8 was not available yet by the time the doc were published.
It does not seem that we 'officially' support RHEL 6.8. The documentation site (CA Technologies Documentation ) is intended to be a living document with any new certifications being added as they are tested. The compatibility matrix was updated as of September 2016 while RHEL 6.8 was released around May 2016 so it seems to have been intentionally left off.
While I am not aware of any particular problem we have not officially tested this.
