Oracle changes Solaris 11.4 SRU delivery

In the past Oracle provided Solaris SRUs (Support Repository Updates)
each month. This does change now. The types of SRUs are reduced
from 3 types to 2 types. Instead of 12 SRUs per year we will see 8 SRUs
per year.

a) Feature SRU (NEW)

This will be available early in the months 
March, June, September, December
Around 6 weeks after the CPUs.

This SRU includes new features, tools, packages, version updates
and removal of old, outdated/insecure software.

I would recommend to install this SRU on test systems to verify
application compatibility and identify required configuration changes.


b) CPU (Critical Patch Updates)

No changes here. 

Available January, April, July, October
The release dates are predefined and are published on
https://www.oracle.com/security-alerts/#CriticalPatchUpdates

This SRU includes critical fixes and security updates.
Most of our enterprise customers update to this SRU.


For critical issues Oracle will release individual 
IDRs (Interim Diagnostic or Relief).
