For many, that's all they need to know. For others, there are some more points worth discussing. Read on, if that may interest you.

For instance, what's the version of Solr? (It's considerably upgraded over what was in CF11 and 10). What about Java, Tomcat, Hibernate, ehCache, 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 (2016 Release). I also explain how I found these version numbers, which isn't always obvious, in case that may help others. But I also offer some commentary on why this is an important issue to some, and I offer 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. :-)

And while that Adobe blog post mentions a few of the main new features, as is nearly always the case it leaves out many other new features which may interest folks. It also doesn't point to resources to learn more. I do those things here in this post.

Has this happened to you? You wanted to update the JVM which CF uses to use a new version...

• so you found some resource on the web showing how to update, and it seemed simple enough
• and then you tried restarting CF and wham, it won't start, or the admin won't open, or code starts failing
• and maybe it's that things didn't fail immediately, but within hours or days folks report things breaking since you made the change
• and now you're stuck wondering, "what happened? and how am I supposed to fix this?"

It's a tough position to be in, and tragic of course if CF won't start. But no, you do NOT need to reinstall CF!

Often it's just one thing you did by mistake, though there are indeed several possible reasons why your attempt to update CF's JVM can fail or lead to unexpected problems. And as you google about, you may find all kinds of helpful but often misinformed or spartan suggestions that may or may not help much.

So I offer here over a dozen of things you can and should consider/look at, some of which you may quickly recover from or be able to undo (depends on what you did). And all this applies to Lucee, Railo, and BlueDragon as well, though folder locations will differ.

If you're facing this bind right now, you can skip over the following to the the section, "Seeing better error info, when the CF service won't start", and then the section after that "So what went wrong?", where I present each likely problem and solution.
