In this post, I point out how one can participate in the prerelease (including seeing its substantial docs and obtaining the prerelease update adding the new features). I can't share news of what's IN the new version, per the info available in those prerelease docs. But in a follow-on post I will offer links to the recordings of several recent Adobe webinars, from mid-April 2026, where Adobe CF team members shared several hours of presentations about what's coming (again on more than just the new AI features).

Here are the topics I cover in this post.

• Accessing the prerelease"
• Available prerelease docs: hundreds of pages
• Available prerelease forums
• Implementing the prerelease: via an update or via a new CF2025 installer
• What the new installers offer, if used
• What about CF2023?
• What about CF2026? Seems it will be a CF2027
• When is this CF2025 update coming out? That's NOT been announced. Where to watch

TLDR: The new updates are 26.0.1, 25.0.3, 21.0.11, 17.0.19, 11.0.31, and 1.8.0_491 (aka 8u491) respectively. The update seems a pretty modest one, without seeming breaking changes (though my opinion is based solely on my read of the update release notes, in this first day).

More on the updates below, including links to more info on each of them including what changed, bug fixes, and the security fixes each version contains. (I also offer a quick assessment of the changes listed for the updates.)

Also, openjdk updates are usually released at the same time or soon after, so this info may help users of such alternative JDK implementations.

For some folks, the above is all they need to hear. For others, whether this your first time updating Java or your fiftieth, there are some things that you may or may not know, as I cover here.

(This is the second update since CF2021 has reached its end of life as I blogged previously, which is something folks running that should beware. You are now QUITE exposed to things fixed in these two updates, for which there is no fix for you.)

In this post, I share the details about the update (from Adobe and from others). I also share additional info you may want to consider before (or after) doing the update.

For more, read on.
