FeatureIDE v2.6.3 (September 2012)

• Support for arbitrary feature names in feature diagram and constraint dialog
  (features containing whitespace must be placed within quotation marks in the
  constraint dialog; works only when no generator is selected for this project)
• Enhanced removal of features that occur in cross-tree constraints (feature
  references in constraints are replaced by other features if possible)
• Warnings for indeterminate hidden features (a hidden feature H is
  indeterminate if there is no constraint A <=> H, where A is a conjunction of
  non-hidden features and there is no logically equivalent non-hidden feature
  that can be used to determine the selection of H)
• Enhanced collaboration diagram with support for printing, showing
  methods/fields
• Support for colors in Antenna and Munge projects as known from
  FeatureCommander
• Detection of contradictions and tautologies in preprocessor directives for
  Antenna and Munge
• Efficiency of feature diagram drawing improved
