Is there a solution I have missed? I would prefer a open source tool, not just a 1-5-developer free plan (so not BaseCamp, Mingle, Jira/Greenhopper). And it has to run on both windows and linux (so no ScrumDesk or TargetProcess). It has to support agile development process - user stories, iterations, point estimates, tasks etc.
What i really would love to have is a mylyn connector for agilefant. But agilefant has no public API, so it is not even possible to do anything about it AFAIK.
I have read this post and this post about free bug tracking tools with mylyn integration, but what i am looking for is different as i would like a project management/ALM tool
