0.4.2

Bug Fixes

• Detaching a vertex correctly removes it from the list of successors of its
  predecessors.
  Samuel Giddins
• Vertices orphaned after swapping dependencies are properly cleaned up from the
  graph of activated specs.

0.4.1

Enhancements

• Ensure every API is 100% documented.

  #22

0.4.0

API Breaking Changes

• The DependencyGraph no longer treats root vertices specially, nor does it
  maintain a direct reference to edges. Additionally, Vertex no longer
  has a reference to its parent graph.

Enhancements

• Resolution has been sped up by 25x in some pathological cases, and in general
  recursive operations on a DependencyGraph or Vertex are now O(n).
  Samuel Giddins
  Bundler#3803
• Re-sorting of dependencies is skipped when the unresolved dependency list has
  not changed, speeding up resolution of fully locked graphs.

0.3.1

Enhancements

• Add Conflict#activated_by_name to allow even richer version conflict
  messages.
  Samuel Giddins

Bug Fixes

• Ensure Conflict#requirement_trees is exhaustive.
  Samuel Giddins
  Bundler#3860

0.3.0

Enhancements

• Add the ability to optionally skip dependencies that have no possibilities.

Release 0.2.2

0.2.1

• Allow resolving some pathological cases where the backjumping algorithm would
  skip over a valid possibility.

0.2.0

Release 0.2.0

0.1.2

Enhancements

• Improve performance in highly conflicting situations by backtracking more than
  one state at a time.
  Samuel Giddins

Bug Fixes

• Ensure that recursive invocations of detach_vertex_named don't lead to
  messaging nil.
