93 // - Cflow specializers
94 // - Restructuring of the MethodCut, SetCut, ExceptionCut, and GetCut (they are much smaller)
95 // - Transactional capabilities
96 // - Total refactoring of Specializer evaluation, which permits fine-grained distinction
97 // between static and dynamic specializers.
98 // - Functionality pulled up in abstract classes
99 // - Uniformization of advice methods patterns and names

105 // Important refactorization step (march):
106 // - removal of 'JoinPointEvents'; JoinPoints now have the same function as events
107 // - reimplementation of the JVMAIDebuggerAspectInterface (better performance, coding conventions, removal of ProseVM
108 // structures
