Upgrade information for newer versions are available in the changelog or upgrade guides found on marionettejs.com.
A lot of changes were made between v2 and v3. Please see the upgrade guide on the website for the full list of changes and how to migrate to Marionette 3.

If you are overriding appendHTML in your collectionView or compositeView make sure to update your method to match the buffering implementation. If you do not you may observe the show event not being called per itemViews

v1.1.0 adds a few new features, but should not break any existing API or behavior. It should, therefore, be a drop-in replacement for v1.0.x.
Please see the changelog for the complete list of what was added and fixed in this release.
In addition to the following notes, please see previous upgrade guide entries and the changelog.
Marionette v1.0 is built and tested with Backbone v1.0 and Underscore v1.4.4. You should be able to use Backbone v0.9.9 or v0.9.10 with Marionette 1.0, but there is no guarantee that everything will work as expected. Older versions of Backbone are not supported at all.
As of Backbone v1.0, calling fetch() on a collection will not trigger the reset event
by default. This will cause Marionette's CollectionView and CompositeView to not function
as expected. Be sure to pass the reset: true option when calling fetch().
This update renames the addHandler methods to setHandler to help
set the expectation that there is a single handler for any given
command or request/response handler. When updating to Wreqr v0.2.0,
you will need to change all calls to addHandler to setHandler. For
more information on other changes in Wreqr, see the
Wreqr changelog.
Grunt v0.4 has a significantly different architecture than previous versions. If you are building Marionette and/or running the specs from your local computer, you will need to update to the latest version of Grunt v0.4 to do so.
See the getting started guide for Grunt.
Once you have done that, you should be able to run Grunt to get things rolling.
This method has been removed. It was never used by Marionette directly, and you should replace its use with a proper polyfill such as Modernizr.
RC4 is mostly bug fixes and zombie killing. There are a few things that you need to pay attention to, though. Check the changelog for a more complete list.
The method Marionette.addEventBinder has been removed
entirely. If you were using this method call in your code,
you will need to delete that line of code.
The replacement for this is simply Backbone.Events, which
has the necessary .listenTo and .stopListening methods,
as noted in previous upgrade guide entries.
The addEventBinder had provided a 4th context parameter
to the .listenTo and .stopListening methods, in anticipation
of Backbone adding these in a future release. After further
discussion and research, though, I realized that this parameter
is not needed. Further, Backbone is not going to be adding this
parameter any time soon. There has not been a clear need for
it.
The Marionette.EventAggregator object did nothing more than
import Backbone.Wreqr.EventAggregator in to the Marionette
namespace. This has been removed as it added no value. Replace
all uses of Marionette.EventAggregator with
Backbone.Wreqr.EventAggregator.
This is a simple update:
- Update Backbone to v0.9.10
- Update jQuery to v1.9.0
Note that there are no changes in Marionette for this minor.
You should not have to change any Marionette specific code
to update your app. You may have to change code that core
Backbone runs, or that jQuery runs, though. This includes
any core Backbone features that are included in Marionette,
such as the use of the view.make function which is no
longer included in Backbone.View.
For more information on what you may need to change, see the change logs for Backbone v0.9.10 and the upgrade guide for jQuery v1.9.0
There are several breaking changes that occurred between v1.0.0-rc2 and v1.0.0-rc3 that need special attention. Please use this upgrade guide as a list of things that you need to account for when updating.
In general, you need to grab the latest version of Backbone, Underscore, and Backbone.Wreqr.
First and foremost, with the release of Backbone v0.9.9, we are no longer supporting Backbone v0.9.2. There are several additions to v0.9.9 that have made code previously found in Marionette's pre-requisites obsolete. This has caused a ripple effect of API changes for naming consistency in Marionette.
In order to use Marionette v1.0.0-rc3, you must upgrade to Backbone v0.9.9 and Underscore v1.4.3 or higher (as necessary, with Backbone versions).
With Backbone v0.9.9, the Backbone.EventBinder pre-requisite is now obsolete. It will be kept around for backward compatibility with older versions of Marionette and Backbone, but it is no longer used by Marionette directly. Unless you have a significant investment in its use, you should discontinue its use when ugprading to Marionette v1.0.0-rc3.
To replace the use of Backbone.EventBinder in your Marionette applications, you have two choices:
- Mix Backbone.Events in to your objects directly
- Use Backbone.Wreqr.EventAggregator
With the introduction of .listenTo and .stopListening to Backbone.Events,
the need for Backbone.EventBinder is no longer there. You can either
use _.extend(myObject, Backbone.Events) to mix in Backbone.Events
directly, or you can use an instance of Backbone.Wreqr.EventAggregator
to replace your Backbone.EventBinder instances, directly.
Along with this dependency being obsolete now, you should make the following changes:
- Replace
bindTowithlistenTo - Replace
unbindAllwithstopListening - Remove calls to
unbindFromas this has no equivalent
The Marionette.Async library was a mistake from the start. It advocated bad practices by making the View layer responsible for the knowledge of application workflow. I'm happy to say that it has been removed from Marionette and is no longer supported.
If your app currently relies on Marionette.Async, I suggest re-thinking the architecture before upgrading to Marionette v1.0.0-rc3 or later. Specifically, move any logic that deals with asynchronous calls, and workflow / process logic out of your views and in to a Marionette.Controller or other object that can properly coordinate the efforts.
For example, loading a model before displaying it:
Marionette.Controller.extend({
showById: function(id){
var model = new MyModel({
id: id
});
var promise = model.fetch();
$.when(promise).then(_.bind(this.showIt, this));
},
showIt: function(model){
var view = new MyView({
model: model
});
MyApp.myRegion.show(view);
}
});
