 # Change History / Release Notes
 
+## Version 1.1.2
+
+* pull #118 (thanks @ahmozkya): remove the deprecated `.live` function, and use `.on` instead.
+  Note: at least jquery 1.7 is required now!
+
+## Version 1.1.1
+
+* added the to be added/deleted element to the event, this allows to add animations/actions onto them
+* added extra option :wrap_object, allowing to use Decorators instead of the association object
+* added an option :force_non_association_create, that will allow to use `link_to_add_association` inside the fields-partial
 
 ## Version 1.1.0

 There is an example project on github implementing it called [cocoon_formtastic_demo](https://github.com/nathanvda/cocoon_formtastic_demo).
 
+Or, you can use the Formtastic `cocoon` field type to wrap up much of the boilerplate of the wrapper and
+add association button:
+
+``` haml
+= f.inputs do

+  = f.actions do

+
+#### Sortable forms
+
+Say you have a set of nested models that are ordered arbitrarily:
+
+``` ruby
+class Task < ActiveRecord::Base
+  belongs_to :project
+
+  default_scope :order => 'order ASC'
+end
+```
+
+You want users to be able to sort those
+models via the UI. You can do this by including `cocoon/ordered` and specifying the sort field in the Formtastic
+input call:
+
+``` haml
+= f.input :tasks, :as => :cocoon, :ordered_by => :order
+```
+
+Add the order field as a hidden field in the nested form:

+``` haml

+    = f.input :done, :as => :boolean
+    = f.input :order, :as => :hidden

 ```
 
+#### :force_non_association_create
+
+In normal cases we create a new nested object using the association relation itself. This is the cleanest way to create
+a new nested object. But this has a side-effect: for each call of `link_to_add_association` a new element is added to the association.
+
+In most cases this is not a problem, but if you want to render a `link_to_add_association` for each nested element this will result
+in an infinite loop.
+
+To resolve this, specify that `:force_non_association_create` should be `true`, as follows:
+
+```
+link_to_add_association('add something', @form_obj, :comments, :force_non_association_create => true)
+```
+
+By default `:force_non_association_create` is `false`.

 > A cleaner option would be to call a function that performs this initialisation and returns `self` at the end.
