| title: Immutant 2 (The Deuce) Beta2 Released | ||
| author: The Immutant Team | ||
| version: 2.0.0-beta2 | ||
| layout: release | ||
| tags: [ releases ] | ||
| --- | ||
|
|
||
| We're [just bananas](https://www.youtube.com/watch?v=nTqn72B2Ajk) to | ||
| announce *The Deuce's* second beta: Immutant **2.0.0-beta2**. At this | ||
| point, we feel pretty good about the stability of the API, the | ||
| performance, and the compatibility with both WildFly 8 and the | ||
| forthcoming WildFly 9. | ||
|
|
||
| We expect a final release shortly after WF 9 is official. We would | ||
| appreciate all interested parties to try out this release and submit | ||
| whatever issues you find. And again, big thanks to all our early | ||
| adopters who provided invaluable feedback on the alpha and incremental | ||
| releases. | ||
|
|
||
| ## What is Immutant? | ||
|
|
||
| Immutant is an integrated suite of [Clojure](http://clojure.org) | ||
| libraries backed by [Undertow] for web, [HornetQ] for messaging, | ||
| [Infinispan] for caching, [Quartz] for scheduling, and [Narayana] for | ||
| transactions. Applications built with Immutant can optionally be | ||
| deployed to a [WildFly] cluster for enhanced features. Its fundamental | ||
| goal is to reduce the inherent | ||
| [incidental complexity](http://en.wikipedia.org/wiki/Accidental_complexity) | ||
| in real world applications. | ||
|
|
||
| ## What's changed in this release? | ||
|
|
||
| The biggest change in this release is a [new API] for communicating | ||
| with web clients asynchronously, either via an [HTTP stream], over a | ||
| [WebSocket], or using [Server-Sent Events]. As part of this change, | ||
| the `immutant.web.websocket` namespace has been removed, but | ||
| `wrap-websocket` still exists, and has been moved to | ||
| [immutant.web.middleware]. For more details, see the [Web Guide]. | ||
|
|
||
| In conjunction with this new API, we've submitted changes to [Sente] | ||
| that will allow you to use its next release with Immutant. | ||
|
|
||
| For a full list of changes, see the issue list below. | ||
|
|
||
| ## How to try it | ||
|
|
||
| If you're already familiar with Immutant 1.x, you should take a look | ||
| at our [migration guide]. It's our attempt at keeping track of what we | ||
| changed in the Clojure namespaces. | ||
|
|
||
| The guides are another good source of information, along with the | ||
| rest of the [apidoc]. | ||
|
|
||
| For a working example, check out our [Feature Demo] application! | ||
|
|
||
| ## Get It | ||
|
|
||
| There is no longer any "installation" step as there was in 1.x. Simply | ||
| add the relevant dependency to your project as shown on [Clojars]. | ||
|
|
||
| ## What's next? | ||
|
|
||
| We expect to have a fairly short beta cycle, with a final release once | ||
| we ensure that everything works well with the upcoming WildFly 9 | ||
| release. | ||
|
|
||
