Following concerns with the way the feedback and patches from the Redmine community were being handled[9] a group of Redmine developers created afork of the project in February 2011.[10] The fork was initially named Bluemine, but changed to ChiliProject.[11] After the leader of the fork moved on from ChiliProject in 2012[12] and development and maintenance had been announced to shut down, the project was officially discontinued in February 2015.[13]
Another fork of ChiliProject calledOpenProject is active since 2015.[14]
