+Intro
+=====
+
+Drools solver isn't backwards compatible at the time.
+This file describes how can you upgrade from earlier versions to the latest.
+
+From m2 to next
+===============
+
+TODO commit the refactor below
+
+New interface score (replace score as a double) and new class ScoreHolder (replaces ScoreCalculator)
+----------------------------------------------------------------------------------------------------
+
+The score isn't a double any more, now it's an implementation of the interface Score.
+The *ScoreCalculator classes have been replaced by a ScoreHolder.
+
+If you're using a HardAndSoftConstraintScoreCalculator:
+
+    Old code:
+        import org.drools.solver.core.score.calculator.HardAndSoftConstraintScoreCalculator;
+        ...
+        global HardAndSoftConstraintScoreCalculator scoreCalculator;
+
+    New code:
+        import org.drools.solver.core.score.holder.ScoreHolder;
+        import org.drools.solver.core.score.DefaultHardAndSoftScore;
+        ...
+        global ScoreHolder scoreHolder;
+
+Or if you're using a SimpleScoreCalculator:
+
+    Old code:
+        import org.drools.solver.core.score.calculator.SimpleScoreCalculator;
+        ...
+        global SimpleScoreCalculator scoreCalculator;
+
+    New code:
+        import org.drools.solver.core.score.holder.ScoreHolder;
+        import org.drools.solver.core.score.DefaultSimpleScore;
+        ...
+        global ScoreHolder scoreHolder;
+
