ColdBox has always provided nice, automatic error handling for your code.  Errors in your application are caught for you, and you can respond to them via convention-based methods, event handlers, or even interception points as you see fit.  (Read more on ColdBox error handling here)

If you do nothing, ColdBox will render a nicely formatted page with all the original exception information plus extra details about the ColdBox request which can be handy for debugging.  Due to our focus on security-by-default in ColdBox 4, we found that a large  number of people never change the default error template and their production servers give out way too much information!  Even though having a 'detailed' template by default was convenient, it wasn't secure.  

The new modular approach of ColdBox 4.0 means much of its built-in functionality has been moved to separate, installable modules. One of the many new modules introduced with ColdBox 4.0 is the Validation Module. To install, simply fire up CommandBox.

In ColdBox 4 we have expanded the runEvent() method to allow you to add caching parameters so ColdBox can take care of caching output from events.  This is a great way to accelerate the execution of widgets or viewlets within an application as it will execute them and cache them as needed.  Here is the new signature for the runEvent() method.

ColdBox 4.0 is the most significant change in the framework since it was first introduced. Go ahead - let that soak in a bit.

Now, what do I mean by that? Lots. Too much for a single blog post to do justice without becoming tl;dr. That's just how big these changes are.

ColdBox 4.0 has been built for speed.  We really wanted to improve performance out of the box.  We spent a lot of time making sure, as we always do, that we can squeeze everything out of the framework as possible.  

One of the major changes you should be aware of in terms of performance is that ColdBox handlers are now singletons out of the box. Most applications should be using their handlers as singletons because controllers generally shouldn't have state in an even...
