+### 2.5.5
+
+- Support observing an array object index directly (e.g. `ModelBinding.new(array, '[0]')` as opposed to `ModelBinding.new(self, 'array[0]')`)
+- Extract Shine data-binding expression from Glimmer DSL for SWT to Glimmer as a reusable class: `Glimmer::DSL::ShineDataBindingExpression`
+- Avoid compacting model with property in `ModelBinding` yet only compact property/args and keep model as is get a better error message in the case of a `nil` model
+- Document data-binding options like on_read, after_read, etc...
+
 ### 2.5.4
 
 - `Glimmer::DataBinding::ObservableModel` support for observing model attributes with specified `:attribute_writer_type` option (default: `:attribute=`), which can be a single symbol or an array (e.g. `attribute_writer_type: [:attribute=, :set_attribute]`). Glimmer automatches attribute name and automatically generates observer notification attribute writer methods.
