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

Note: This blog post is from 2019. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
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 in recent CF releases

Did you know that when you update ColdFusion, there is often a need to also update ("upgrade") the web server connector (for IIS and/or Apache)? Did you know that's gotten easier to do since CF2016 came out?

In this post (updated in Oct 2023, for reasons discussed below), I discuss:

Preview available for new ColdFusion updates for CF2016 and 2018

Note: This blog post is from 2019. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
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.

Come speak on the CFMeetup (online CFUG). A FAQ for prospective speakers

Do you have a presentation you've given or would like to offer to a CF/CFML audience?

There is a waiting audience of a couple thousand members of the Online ColdFusion Meetup, the online CF user group which I host, who would love to see your talk and/or its recording that we'd make. This post is a FAQ for such prospective speakers.

TLDR: We'd love to have you present. Anyone can. You don't need to have a webcam: it's just your presentation and/or demos, via screenshare. We can meet about any week. Let me know if you're interested. See the first bullet below.

Adobe should consider a different model for handling ColdFusion security fixes

Note: This blog post is from 2019. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
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

Note: This blog post is from 2019. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
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.

For more, read on.

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

Note: This blog post is from 2019. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
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.

Configuring FusionReactor to show "real ip address" when behind a load balancer or other proxy

If your server is behind a load balancer or other sort of proxy, you may have noticed that when you view information about requests in FusionReactor, they all have the same (or nearly the same) IP address. This can be easily fixed, and I show you how in this post.

Speaking at CFCamp 2019, for the 10th talk/7th year!

Note: This blog post is from 2019. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
Following on my recent announcement about speaking at CF Summit 2019, I am delighted to announce also that I've been selected to speak at CFCamp 2019, in Munich this October.

This will be my sixth year in a row presenting at this wonderful event, and my seventh year total. It will also be my 10th presentation there. (You can see all my past presentations, including when and where offered, at carehart.org/presentations.)

FWIW, half of those talks have been "sponsor" presentations on behalf of Intergral, the makers of FusionReactor, while the rest were not. And despite the title of my talk this year, "Comparing Monitoring Solutions for CF and Lucee", it is NOT an FR-sponsored talk. See the description below, for more.

CF2020 to offer still-better deployment on Docker, cloud

Note: This blog post is from 2019. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
There's great news coming regarding Adobe ColdFusion 2020, with regard to deployment of CF via Docker images and/or in the cloud.

Adobe's Director of Engineering for CF, Ashish Garg, recently held a wide-ranging interview with Michaela Light (on the CF Alive podcast) about the CF2020 roadmap. Ashish shared news of some substantial changes planned in the next release regarding modularity in the engine, the size of installers/containers, and their startup time, as well as matters like licensing of containers, logging within them, monitoring of them, and more.
