A bit more than a year since last release...
More output cache options are available (see https://github.com/moonpyk/mvcdonutcaching/blob/v1.3.0/DevTrends.MvcDonutCaching/OutputCacheOptions.cs for details). This release focuses itself primary on bugfixes that the community provided.
A lot of contributions have been made on the demo project where you can find an out of the box demo of the library capabilities.
Work will continue towards next release.
Development has been sponsored by my employer, AM-Créations (http://www.am-creations.fr), who gave dev and testing time.
