          The smaa and hitandrun R packages have been updated:
  - smaa version 0.2: this version introduces a convenience function for computing piece-wise linear partial value functions. It also includes some minor bug fixes.
- hitandrun version 0.2-2: introduces a new method for computing a seed point, since the previous method turned out to be flawed.
