CHANGELOG

@@ -8,15 +8,20 @@ Features
 
 - added constraint handler that checks and enforces bounds on original variables which have been fixed or aggregated in the transformed problem
 - allow for implicit integer variables in xor constraints
-- implemented symmetry detection callbacks for cons_pseudoboolean
+- implemented symmetry detection callbacks for pseudoboolean constraints
 - added option to consider enforcement of nonlinear constraints (including spatial branching) before integrality has been enforced
 
-Performance improvements
-------------------------

 Fixed bugs
 ----------
 
+- make sure that, in dual proof analysis, upgraded constraints can report their number of variables
+- check knapsack constraints as linear constraints to avoid violations based on implicit integrality
+- make sure that symmetry detection callbacks report success
+- make arithmetics in cuts.c more robust to avoid invalid scg cuts due to numerical rounding sensitivity
+- allow to copy pseudoboolean constraints even if no AND constraints are present in order to avoid a warning
+- set value for variable that is introduced to reformulate nonlinear objective function when reading .nl files with initial solution
+- fixed that multi-aggregations from PaPILO were accepted without ensuring that their bounds hold
+
