Version numbers of libraries underlying ColdFusion 2021

Are you wondering what updates have been made (in terms of version numbers) to the libraries underlying CF2021?

For instance, what's the version of ehcache? What about Java, Tomcat, Hibernate, Quartz, jQuery, and so on?

In this post, I offer a rundown of what seem the most significant libraries and their versions, as deployed in the first release of ColdFusion (2021 Release). This is something I have been doing in my "hidden gems" talks for the past several releases. I also explain here how I find these version numbers, which isn't always obvious, in case that may help anyone (and also because some libraries may change with future updates to CF2021). I also offer some commentary on why this matter of library versions is important to some, as well as some counterpoints to the demands some have that every library should always be the absolute latest version (and why that's just not practicable).

If you just want the version numbers without the "waffle", look for the bulleted list of them below. :-)

Be aware that updates to ColdFusion 2016 will end Feb 2021

Are you still running ColdFusion 2016? Did you know that its "core" support (meaning, public updates from Adobe) will end in just a couple of months, Feb 21 2021? Same for CFBuilder 2016.

The recent release of CF2021 is a great sign for the continued vitality of CF, but this looming deadline is a reminder that as the years roll on, we not only get new versions but we say good-bye to old ones.

Wondering what you can do? or when CF2018 or CF2021 support ends? And what's the difference between "core" and paid Adobe support plans? For more on these, as well as official Adobe documentation that discusses such things, read on.

How and why your sites may break, and what to do, after applying March 2020 update to CF2018 or 2016

This is a critical warning to anyone who may apply the recent CF2018 Update 8 or CF2016 Update 14, released Tuesday of this week. To be clear, I do not mean with this warning to suggest that you should NOT apply the update! It implements an important security fix.

Instead, it's that after applying it, your CF web sites served via IIS or Apache WILL likely break initially, until you take one at least and perhaps two extra steps. The good news is that these steps are both easy and documented by Adobe in the update technotes, but they do require that someone do them, if needed. Let me explain.

[Update: I did an abbreviated version of this post on the Adobe CF portal: Three reasons your sites may break, and how to fix them, after applying March 2020 update to CF2018 or 2016. Note I also titled it differently. Just trying many ways to get people's attention. That post may interest some, either to read first (but my TLDR below also tries to abbreviate things also), or especially if you may prefer to give others a link to a post on this matter that is not as "dense" as this one. :-) I do point to this post from there, of course, for the many additional details that some may appreciate.]

Sadly, because many people don't bother to read the CF update technotes (linked to below), and they just apply the CF updates, they are not noticing this issue until they or their users start screaming because their sites are down. There's also a fair bit of "screaming" in the CF community, and folks responding may not know the info that I (or Adobe) have shared, to get things "working again", so I hope this helps bring some calm, and most important the clear solution/s needed.

ColdFusion 2018 update 7 released today...do you "need" it?

Adobe released update 7 for CF2018 today, and as it includes a security fix, some might think I'd say everyone should apply it.

But note first that the security aspect applies only to those running CF on Windows (and even then not ALL users of CF on Windows, as I will explain).

Then again, the update also includes a bug fix to a CF Admin, for a UI issue (related to updates, in fact), and if you need that, then you do want the fix (regardless of your OS).

So who needs it? If you need a little more guidance, I offer some clarification, as well as links from Adobe for more.

When and how to upgrade CF web server connector, easier since CF2016

Did you know that when you update ColdFusion, there is often a need to also update the web server connector (for IIS and/or Apache)? In this post, I discuss how you can know when to do it (Adobe makes that easier since CF2016), as well as how to do it (also easier since CF2016), and why it's important.

Preview available for new ColdFusion updates for CF2016 and 2018

Update (Nov 20, 2019): Adobe announced today that they'd come out with the "final" versions of this pair of "preview" updates. If you already applied either one, you don't need to do the update, as they are unchanged from the preview. But do note that if you changed your CF Admin update "settings" feature to point to the new "preview" feed url, you should use the button there to revert back to the default update feed url.

Adobe has announced today (Nov 13, 2019) new preview updates for ColdFusion 2016 (preview update 13) and 2018 (preview update 6).

https://coldfusion.adobe.com/2019/11/preview-builds-coldfusion-2018-release-update-6-and-coldfusion-2016-release-update-13-released

These updates address issues reported with the Sept 2019 updates (which I was tracking and warned about when the update was released). If you experienced any of those or other issues discussed in Adobe's post, you should try out the new updates while they are in this preview mode (to share with Adobe any remaining concerns) over the next couple of weeks.

Notice also my initial comment in that Adobe post, with a couple of potentially important reminders regarding the preview, as well as a reminder of my plea for a new approach to updates that would allow one to select to get only the latest security updates of a new update (deferring any bug fixes or new features to the next update), which could have helped many in the case of the Sept updates, that had so many issues seemingly caused by new features and bug fixes.

Adobe should consider a different model for handling CF security fixes

I would like to publicly propose a new model that Adobe should consider following for handling CF updates, specifically allowing for one to implement security fixes as soon as possible, without being ill-effected by possible problems introduced by other bug fixes/new features.

There is precedent for the proposal I am making, in the way Oracle has in the past handled this problem with Java updates. Let me explain.

Folks may want to hold off on the Sep 24 2019 CF updates

Update (Nov 20, 2019): Adobe announced today that they'd come out with a new set of updates to fix the problems in the Sep 24 updates. Today's updates address the various issues reported below about the Sept update. It's important to proceed with performing the updates, for the benefit of the security updates as I discussed below back in Sept.

I shared here Tuesday the news that Adobe had announced there were new updates for CF2018 and 2016, released that day.

But as has happened every few releases, a lot of folks are reporting various problems, enough for me to say that folks may want to hold off on applying these updates, which I realize is a risky proposition since the update includes security fixes. More on that below.

Update Nov 13: Adobe has released a preview of new updates, meant to address the issues in these Sep 2019 updates. For more, see my post: https://www.carehart.org/blog/client/index.cfm/2019/11/13/preview_available_for_new_coldfusion_updates//

Update Sep 27: Adobe has commented below (Sep 27) saying that there are now fixes available for the bugs reported (but that you must request each directly from them, and that an update refresh is not planned). See Vamsee's comment below, and my reply to that (asking for a bit more detail). For now, I have added any links I've seen to fixes for any of these.
--

Of course, if you need something in the update and want to try it, just be sure to do ample testing, and check out some of the problems people are reporting below. And beware that some issues may only happen under load, so you may not find them in your own testing.

Otherwise, let's see if Adobe may either "refresh" the update or may well "pull" it, as they did with the Feb 2019 updates for CF 2016 and 11, when they replaced those with another a week later (see the "Note" about it at the top of that page).

For more, read on.

Sep 2019 updates released for CF2018 and CF2016, with a strange twist

Adobe has announced today Sep 24 2019 that there are new updates for CF2018 (update 5) and CF2016 (update 12).

As an update to this post, I have offered a new post, pointing out that many people are having problems with this set of updates here. So I would recommend folks hold off on applying it for now. I will update this (and that) if we hear new info from Adobe.

Beyond adding important security and bug fixes as seems typical, this update offers several new or changed features, as well as updated support for things (such as Java 12), as is also often the case.

Uniquely, though, this update is the first ever to require that you must first have updated to the PREVIOUS update before applying this new one. So those on CF2018 must first be on update 4 before going to this new update 5, while those on CF2016 must be first on update 11 before going to this new update 12.

As always, I share a bit more here, for my readers.

Updates released today for CF2018, CF2016, and CF11

While word has been shared elsewhere about this today already, I wanted to share here also that there were updates released today for CF2018, CF2016, and CF11.

And I share a bit more here, for my readers.
