Further reading on the 3.5.1 release note revealed that 3.6 is planned for late June 2018.
With that being said, we may want to wait the 3.6 release since it just a matter of days/weeks before it's official release. "This release allows distribution packagers to update to a new upstream release before the final release of 3.6. The 3.6 release will include further enhancements in core sosreport functionality and is planned for late June 2018." Regards, Eric
