This file lists the major changes and improvements made to AspectC++ 
and the PUMA framework. 

Version 0.6pre2 (2002-07-08)
	* First Win32 release (using cygwin cross compiler 2.95.3 for mingw target)
	* Fixed examples for Solaris platform
	* Added support for -e switch to specify extension(s) for C++ files 
	* Added support for pointcut of type class as argument for call and execution
	* Some minor code generator changes 
	* Many parser extensions to handle non standard header files (GNUC, BCC, VC)
	
Version 0.6pre1 (2002-05-10)
	* Now compiles with gcc3.1
	* Fixed many small bugs 
	* Improved code generation (inline declarations, casts, type
	information, forward declarations, ...) 
	* Added basic exception support in PUMA
	* Changed all examples to use stdio instead of iostream
	
Version 0.5 (2002-04-05)
	* Added support for nested around advice
	* Added support for operator functions (as join points)
	* Added support for dynamic Action objects
	* Changed ThisJoinPoint-API:
	  - type of source (that()) and target (target()) object now available
	    via JoinPoint::That/::Target typedef
	  - that() and target() now use actual pointer type if possible
	  - changed toString(), args(), argtype(int), signature(), id(), 
	    resulttype(), jptype() into static member functions of JoinPoint -
	    now accessible via thisJoinPoint-><method> (deprecated) or JoinPoint::<method>
	* Improved code generation
	  - handling of aspect attribute access in advice
	  - handling of user defined aspectOf functions
	  - merged per advice ThisJoinPoint structs into single per join point struct
	  - on demand generation of action objects and wrapper functions
	
	
Version 0.4 (2002-03-05)
	* New language features: introduction of base classes; user defined aspectOf functions
	* Support for Actions, proceed() in around advice (thisjoinPoint->action().trigger()); 
	  (limited to one around advice per call or execution join point)
	* Improved code generation (ThisJoinPoint now as struct not class) -> smaller memory footprint
	* New examples:
	  o Action: demonstrates around advice for execution and call join point with thisjoinPoint->action().trigger()
	  o Cache: very simple Action cache
	  o ID: illustrates usage of thisJoinPoint->id() 
	  o IconCache: implementation of an application specific cache 
	
Version 0.4-pre3 (2002-02-12)
	* Added Support for "within" pointcut function
	* Fixed some bugs in the code generator
	
Version 0.4-pre2 (2002-02-06)
	* Added rudimentary support for templates in PUMA
	
Version 0.4-pre (2002-01-29)
	* Minor changes to compile on Solaris
	
Version 0.3-fix1 (2002-01-24)
	* Changed code generation for call join points
	* Fixed a little strange bug in PUMA that prevented a correct code generation in
	  some special cases
	
Version 0.3 (2002-01-17)

	* Added support for call join points (functions, methods, _no_ operators)
	* New methods for the thisJoinPoint pseudo object
	  - void* that(): gives the pointer of the callers object (if known, otherwise 0)
	  - void* target(): gives the pointer of the target object (if known, otherwise 0)
	  - int jptype(): gives the numerical type of a join point
	  - void* result(): gives pointer to memory holding the result of a call (or 0 if unknown)
	  - char* resulttype(): gives mangled type of result
	* Changed thisJoinPoint->typeinfo(int) into ->argtype(int)
	* Added support for virtual pointcuts
	* Added support for wrapping functions with default arguments
	* Fixed generated code for around advices, wrapper code for static functions
	* Fixed bug in PUMA project managment (path handling)
	* Minor improvements to the PUMA parser
	* More C++ ABI v3 name mangling support
	
Version 0.2 (2001-12-03)

	* New methods for the thisJoinPoint pseudo object
	  - unsigned id(): gives a unique identifier of the join point
	  - const char* signature(): gives the signature of a method join point (C++ ABI v3 name mangling)
	  - const char* typeinfo(int): gives the mangled type of a method argument
	* Extended Trace example: uses the new thisJoinPoint methods for an universal trace aspect
	* Replaced last Flex scanner with Orange equivalent 
	* Fixed some internal PUMA bugs
	* Removed some minor memory leaks from PUMA
	* Added basic C++ ABI v3 name mangling support to PUMA
	
Version 0.1 (2001-11-06)

	* Added automatic dependency mechanism
	* Removed some serious memory leaks from PUMA
	* Fixed some internal PUMA bugs
