PUZZLE is a maximum likelihood program for analysis of
molecular sequence data.

After 15 months of stable sources the first bug-fix update
PUZZLE 4.0.1 is now available.  No new features have
been added in comparison to version 4.0 but a number of
smaller (and also one severe) problems have been resolved.

Generally, an update seems to be absolutely necessary if
you are using PUZZLE in conjunction with the mtREV-24 matrix.


What=B4s new in PUZZLE 4.0.1:=20

- correction of mtREV matrix:
      wrong likelihood values for this model

- fix of the "intree bug":
      prevents PUZZLE 4.0 from reading some input trees

- stringent runtime-compatibility check removed:
      prevents PUZZLE 4.0 from running on alpha
=09 =20
- more accurate gamma distribution:
      16 instead of 8 categories, better alpha > 1.0

- update of documentation:
      mainly address changes

- more Unix-like file layout, and

- change of licence to GPL
