It's always a thrill returning to these annual events. Following is the topic description and more.
Now that CF2025 has come out, supporting Java 21--and as ColdFusion and Java versions continue to evolve--you may wonder which version(s) of Java you can use with your current (or a given) version of ColdFusion.
You can't just use "any" jvm version with CF: it depends on first on what version of CF you are using, and then may even depend on what CF update has been applied to that CF version. (You also can't use Java from any vendor: Adobe supports only use of Oracle Java, and they license it for our use, as I discuss later.) And to be clear, currently ONLY CF2025 supports Java 21. (And though Java 25 came out in Sep 2025 as the latest LTS or "long-term support" Java releases, note that NO CF version currently supports that--as of an updated check in May 2026.)
So in this post, I offer a table that clarifies things, listing the various recent CF versions (even those no longer supported) and what (LTS) Java versions they supported, including if some CF update of a version changes the Java version supported.
First, for more on the many features and changes, I share many Adobe resources--about which I also offer some additional comment. I also discuss changes regarding OS and DB support as well as the fact that CF2025 now runs on Java 21-- and that the traditional server deployment of CF comes installed atop Tomcat 10.1. I then share still more info on other matters and resources related to the new version.
I then focus on the major change in licensing, for CF2025 and forward, to being subscription only--which I'll note has no effect on those currently running CF2023 or earlier. I share pricing info and also help in assessing differences in the EULA, and more.
Finally I discuss some migration considerations--including important REMOVAL of some older features from CF2025, as CF continues to be made more secure and modernized. I also identify tools and resources to help aid you in that migration, when you're ready to begin attempting it.
For all that and more, read on.
TLDR; Now through Feb 28, 2025 those running CF9, 10, 11, 2016 or 2018 can upgrade to CF2023 for 25% off its full price. (Those running CF2021 can already/always could upgrade at 50% off the full price.)
This is a deal offered only by Intergral, makers of FusionReactor, who are also resellers of CF. Adobe doesn't even offer this deal themselves. For more, see their blog post at https://fusion-reactor.com/blog/news/save-25-on-adobe-cf2023-upgrades/.
Act now, it could save you hundreds or even thousands of $$s on a single license! For more, read on.
What about more recent releases, if you may wonder? CF 2023 (the current latest release) will get updates into 2028 (5 years after it was release). And there's the coming CF 2025 release, currently in pre-release (as I have recently blogged about), which is of course a great sign for the continued vitality of CF.
But this looming deadline for CF2021 is a reminder that as the years roll on, we not only get new versions but we must say good-bye to old ones.
Wondering what you can do? or when CF2023 or CF2025 support will end also? And what's the difference between "core" support and the available "extended" support which Adobe sells? (The extended support plan does NOT provide updates beyond this coming November.) For more on these, including official Adobe documentation that discusses such things, as well as my thoughts on migration, costs, various options to consider, and more, do read on.
If you've not yet heard, Adobe has opened the prerelease program for the next CF version, aka ColdFusion 2025--though referred to by them for now as Project CFNext. Adobe announced the opening of the beta a few weeks ago in a post on the CF Portal as well as in various social media. And you can request to join the prerelease program at Adobe prerelease site section for CFNext.
We're currently in the "beta 1" phase, but Adobe has announced that there is a "beta 2" due out early this month.
No news has been shared to indicate when the final version would be released. And while Adobe doesn't ever share info about pricing or editions before the release, but note that they did announce at CF Summit in Vegas (in Oct) that CF2025 would be sold only via subscription model (more below).
They've also shared (publicly) the details of what features will be deprecated or removed in CF2025 (and it's a list with some fairly significant changes). Again, for more see the resource list below.
