This 0.1.0 release contains a bunch of improvements related to the handling of idle resources on the cluster. Previously map/reduce slots would be launched via TaskTrackers when new jobs are submitted, and over time on a busy cluster the ratio of map/reduce slots could get slightly skewed and be less than ideal, often resulting in idle map/reduce slots. More details of related issues can be seen in #32 and #33.
