I, for one, am glad Ember is still going strong. And, as a heavy emberjs user, most of these changes feel like a step in the right direction. But after reading through the change log blog, I have several questions (not complaints) for the core team (in case Dale / Katz and cronies are reading this):<p>1. What happened to the server fast-boot thing? I was under the impression you guys wanted to ship it with 2.0; has that feature been scrapped / moved into a separate project altogether?<p>2. There was no mention of the deprecating changes to the initializer API (i.e. the splitting into instanceInitializer and vanilla initializer). Have we gone back to the old initializer API in 2.0?<p>3. With the removal of action bubbling, do we now have to manually bubble up actions that start in some nested controller but gets handled in application route? For example, say you have an AdminUserController and it has an action that generates an ephemeral flash message, but you handle flash rendering in your application route. Do you now have to laboriously put an actions: { handleFlash { ... } } on every route along the way?
I am excited about this release. Once things have settled down I think Ember 2.x will have a much shallower learning curve than 1.x.<p>However it is a shame that routable components haven't made it in yet. I'm about to start a new, medium-sized Emberjs project, but I'm unsure whether to wait another 6 (or maybe 12) weeks for this feature. Any suggestions?
Oh dear:<p><pre><code> EMBER 2.0 BETA
Model-View-Controller is replaced by Model-Route-Component-Service.
Two-way bindings are replaced by data down, actions up (DDAU).
</code></pre>
I haven't delved into the details, but it looks like things are starting to move in the direction of React. I'm not entirely surprised. We recently built a full scale app with Ember and Ember Data. Now looking back, React with Backbone feels it could have been an equally good (if not better) choice.
I don't use ember, but random observation: out of the big frameworks, ember seems to be the one people most often use because they chose it, and because of the community. Well done Ember folks.
Here is an interesting story about the flarum forum dev and their switch from ember to mithril due to extensibility problems and performance. Hopefully the auhor will blog some more about his experiences.<p>Mind the bloat if you do not want to sink the boat.
