October 13, 2025 Doug Bidwell

I don’t know about you, but we figured there were Technology Refreshes coming, especially with IBM’s TechExchange 2025 developer conference going on last week. However, unlike in past years, we didn’t get any advanced warning. So check out the initial coverage of the new TRs for IBM i 7.5 and IBM i 7.6 and keep an eye out for the coming weeks of detailed drill-downs.

There is also a pretty serious set of vulnerabilities in the IBM i platform that you need to deal with. Check out Security Bulletin: IBM i is affected by Remote Code Execution, Deserialization of Untrusted …

It’s another quiet week in Lake Security Vulnerabilities Be Gone, with the drought on the Eastern seaboard meeting a cold snap that is bringing autumn colors to the leaves a bit earlier than many had expected or liked. It is better than rain, mind you, except when it starts fires.

The good news is that there were no security vulnerabilities this week. So all secure there if you are up to date.

Here is the rundown of PTF Groups by IBM i release level since we last published:

PTF Groups 7.6:

We are determined to get back in synch with the publication schedule of The Four Hundred and the IBM i PTF Guide, so this week you get three issues of the latter inside of one issue of the former, a necessity because PTFs never rest even if publications do take a breather every once in a while.

PTF Groups 7.6:
- HIPERs – High Impact Pervasive
