Extension is not compatible with old gem "protected_attributes" on Rails 4

[xeagle2]

In order to use release_logs on Rails 4, it's required to upgrade protected_attributes gem to the latest one at least to 1.1.3, however there is no version dependency specified inside of extension.

So, it works with "protected_attributes" 1.1.3, doesn't work with 1.1.0 (and unsure about interim versions)
