 ## Supported versions
   * Rails: >= 4.2.10
-  * Ruby: MRI >= 2.0
+  * Ruby: MRI >= 2.3.8
 
 ## Usage
 The gem defines ``human_attribute_value`` as instance and class method on ``ActiveRecord::Base`` and ``ActiveModel::Model``.
 To translate a value it uses the I18n API. The translations are looked up from the current locale file under the key ``'activerecord.values.model_name.attribute_name.value'`` respectively ``'activemodel.values.model_name.attribute_name.value'`` by default.

+### Strings
+Starting with version 1.2.0, dots in strings are also replaced by an underscore for the lookup (before this was only done for numbers).

 ### Child classes
 For models with single table inheritance (STI), the lookup will start with the translations for the class and go up through the class hierarchy and use the translation for the closest parent if there is any.
