Notes

• on lion (and snow leopard i suppose), make sure you are using a 64 bit install of ghc. Also, unless you are suggesting an edit to these directions, please go ask people on the relevant mailing list or wiki for help :)
• Tested on ghc 7.2.2, assumes you have standard developer things installed on mac, like x11 and stuff
• Also tested on GHC 7.0.4 (Haskell Platform) with XCode 4.3.
• These notes were originally brought to you by Carter Schonwald; the “I” probably refers to him. Eric Kow will refer to himself in the third person).

GHC 7.4.x

• gtk2hs 0.12.2 won't build with ghc 7.4.1, but the current darcs repo for gtk2hs does build

Recently, we've been working on extracting Ember conventions from applications we're working on into the framework. Our goal is to make it clearer how the parts of an Ember application work together, and how to organize and bootstrap your objects.

Routing

Routing is an important part of web applications. It allows your users to share the URL they see in their browser, and have the same things appear when their friends click on the link.

The Ember.js ecosystem has several great solutions for routing. But, since it is such an important part of most web applications, we've decided to build it right into the framework.

If you have already modeled your application state using Ember.StateManager, there are a few changes you'll need to make to enable routing. Once you've made those changes, you'll notice the browser's address bar spring to life as you start using your app—just by moving between states, Ember.js will update the URL automatically.

# ActiveRecord::Base#dup and ActiveRecord::Base#clone semantics have changed to closer match normal Ruby dup and clone semantics.

# Calling ActiveRecord::Base#clone will result in a shallow copy of the record, including copying the frozen state. No callbacks will be called.

# Calling ActiveRecord::Base#dup will duplicate the record, including calling after initialize hooks. Frozen state will not be copied, and all associations will be cleared. A duped record will return true for new_record?, have a nil id field, and is saveable.
