## Revision as of 23:58, 6 July 2012

## 1.1.0

- Trees can be multifurcating with -allow_multi option
- Much faster SPR distance calculations
- Many new options including collapsing unsupported bipartitions, fast consideration of unrooted trees with -simple_unrooted option, starting from a specified tree with -initial_tree option, limiting the radius of considered SPR permutations with -r option (-r 1 uses NNI permutations)

## 1.0.0

- initial program version.
- Computes rooted supertrees that minimize the rooted SPR distance using exact calculations or varying levels of approximation.
- Optionally computes rooted supertrees that minimize the SPR distance to any rooting of a list of unrooted input trees.
- Version used in
*"Subtree Prune-and-Regraft Supertrees."*
