The problem is addressed as follows:
a) The next release - PAM 3.3 - scheduled for first half 2019.
b) The current GA release - PAM 3.2.3.
c) The GA - 1 release - PAM 3.1.4 (scheduled for February 2019)
There are no plans to do anything for earlier SPs on the 3.2.x and 3.1.x codelines. - an SP is the latest sustaining patch level, the SP is not a release in itself.
The only non EOL GA version that has not been covered is the 3.0.x release. There are no plans to do another sustaining SP for that GA - 2 codeline.
