As usual, there are a number of things you should consider before (or after) doing the update, with some discussed in Adobe's resources on the update (there are more than one), and some info that I share below based on my experience helping people apply this and past updates.
In this post, I share the details about the update (from Adobe and from others). I can report I have installed the update for each release on multiple machines and operating systems without any major incidents. As for challenges (common to recent releases) and lessons learned (about this update), read on.
I'll be presenting a talk on this topic, online today, at noon US Eastern, on the CFMeetup Youtube livestream (which will be recorded). Folks who are members of the Online ColdFusion Meetup will have already gotten email notification about this, including the meeting URL, but for those who are not members here are the details:
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.
In this post, I share the details about the update (from Adobe and from others, including pointing to some discussions I've already started online about the update). Note also that while you may read that the update is related to the CF PMT feature, beware presuming it therefore "doesn't apply to you" because you "don't use it". See the next section for more.
Of course, this is terrible timing for an update, but it is what it is. I can report I have installed both updates on multiple machines and operating systems without incident. And I may do a follow-up post on the update as I/we all learn more.
For more details, read on.
Also, if you may be skipping to this update from prior to CF2023 update 7 or earlier, or CF2021 update 13 or earlier, please don't apply the update before reading below my discussion about possible breaking changes introduced in those updates from March and June of this year.

And there's still more to consider. Note that if somehow "it's all too much" for you, I can help directly and likely VERY quickly. See my discussion at the bottom here. Otherwise, for the details, read on.
In this post, I discuss this issue, those options for adding them back, and I also share how I'd found the underlying root cause of the problem: the update has a mistaken internal indication that these packages were updated in this update, when they were not. I'm hoping that Adobe may soon be fixing the problem by creating a new update file, to at least benefit those doing this update going forward. I'll share also the bug report for that (and another on a related matter, about installing multiple packages via cfpm).
As another case where Adobe is opting to sacrifice compatibility for security, the update changes from using the very old default of CFMX_COMPAT (as the default) to using either of a couple different alternatives, depending on the function. And if you're not careful/paying attention, you could break some critical part of your app by applying this update.
TLDR; In this post, I want to share a bit more to help you understand the impact of this update (which I blogged about in June), whether you're a developer or an administrator--and whether you've applied or not yet applied the update. Even if you HAVE done it and "all seems well" (in test or even in prod), do beware there may be nasty problems waiting to bite you that could take time to crop up. I'll explain the issues, and help you find the code using these functions, then help you determine if that code is or IS NOT affected by this change. I'll also discuss some real-world scenarios and challenges, with solutions.
Finally, I'll explain an available JVM arg (-Dcoldfusion.encryption.useCFMX_COMPATAsDefault=TRUE) that can be used to revert this behavior, for those who may feel they need to sacrifice security for compatibility, so as to get to this June update and take their time to address this change in the encryption default. I also explain how the CFMX_COMPAT algorithm DOES still remain available as an option, despite what some have asserted, which may be an acceptable option to use. Then I wrap up with some thoughts on how it may not be so bad that I'm only getting this post out a few weeks after the June update.
For more, read on.
TLDR; (more on each of these points, in the rest of this post)
