I also discuss changes in OS support (saving you having to compare the docs discussing that), as well as the change to CF2023 running on Java 17 (which you could miss, as it's not highlighted by Adobe in any of the announcement resources.) I also discuss changes in the licensing document/EULA (again, to save you having to do that comparison), as well as an observation about pricing (it has not changed since CF2021).

I also discuss some migration considerations and close by pointing out the Hidden Gems in CF2023 talk that I did, based on the prerelease. I plan to update that in time based on this final release.

For some, that news is all they need to hear. For others, read on for more details (including why the delay in my announcing this).

(While I said "thrilled" about my previous two conference announcements, saying "delighted" here is not a downgrade. Just a desire not to sound repetitive!)

My talk will be...

Until this weekend...and it may not be noticeable to all, but I suspect some things will stand out to regular readers, starting with....

I also noticed that it marks my 17th year of blogging here, almost to the day with my first entry posted this same week back then, Apr 15 2006. That's "pretty darn interesting", as Ray Camden might say.

FWIW, I'd also blogged elsewhere--yes, on CF--prior to starting this one. And the first of those posts were in early 1998--so technically it's my 25th anniversary of blogging about CF. :-)

But about that dated site layout...

TLDR: The new updates are 1.8.0_371 (aka 8u371), 11.0.19, 17.0.7, and 20.0.1 respectively). For more on each of them, including what changed and the security fixes they each contain (including their CVE scores regarding urgency of concerns), see the Oracle resources I list below. Oracle calls them "critical patch updates" (yep, CPU), but they are in fact scheduled quarterly updates, so that "critical" nomenclature may sometimes be a bit overstated. And as is generally the case with these Java updates, most of them have the same changes and fixes across the versions as each other, though not always.

Note: If you use the JDK installer and may be coming to this update of Java 11 or 17 having skipped the last update, 11.0.18 or 17.0.6 respectively, please note there is an important change to the installer (for all OSs) which you should consider before proceeding. For more, see my discussion below.

For some folks, that's all they need to hear. For others, read on for topics like:

• Finding more info on these Jan 2023 Java updates
• What about other JVM distributions besides Oracle?
• News for my CF audience (getting the Java updates from Adobe or Oracle, how to update, why you should NOT for now use Java 17 with CF, etc)
• Should you apply the update? how soon?
• Beware a change in the January 2023 JVM update regarding the JDK installer
• Beware a change in the October 2022 JVM update regarding Java no longer trusting jars signed with SHA-1
• Beware a change in the April 2021 JVM update, if you may be skipping over it
• Wrapping up, getting more help

TLDR; For some folks, the above may be all you need to hear: you may be dropping your coffee and donuts now to get the update applied. Still others will see this "huge post" and think, "crap, I don't have time for this". For you, skip to the bottom and its "concluding key points". You can then decide what you think you do or don't "need to know" and pick and choose from the sections as you like.

Finally, for those who prefer because of the importance of all this to be led more carefully through understanding things (in a way that's worked for the many people I have helped so far this week, and is far more than either Adobe or Hackernews has shared), please do read on.
