 0.4.1:
 - full port for Max@OSX
-- completely redesigned message and attribute handling: now hashed and a much more efficient
+- completely redesigned message and attribute handling: now hashed and much more efficient
+- added some prerequisites for usage of flext as a shared library
+- completed Max/MSPs inlet/outlet assist description functionality
+- Max/MSP signal objects: fixed bug of reporting wrong number of inlets
+- put overloaded new/delete into flext support class
 - introduced "Finalize" virtual method, called after all "Init" methods
 - fixed crash issue in flext_dsp when there are NO signal inlets or outlets defined
 	(this is possibly only a problem for the signal2 tutorial example)
@@ -124,6 +128,7 @@ Version history:
 - implemented threading support with the MacOS MP thread library
 - stripped the ThrMutex and ThrCond classes of non-portable (and irrelevant) functionality
 - simplified "ToQueue*" and threaded "ToOut*" message queue mechanism for Max/MSP 
+- deprecated FLEXT_ADDMETHOD_V and FLEXT_ADDMETHOD_A definitions which only lead to confusion
 
 0.4.0:
 - the use of the const keyword is enforced (e.g. the preferred type for symbols is now "const t_symbol *")
@@ -289,6 +294,7 @@ general:
 - add log messages for debugging version
 - feed assist function with in/outlet description
 - MaxMSP: how to call separate help files for objects in a library?
+- use PD's t_float type for floating point values (and what about t_int?)
 
 bugs:
 - PD: problems with timed buffer redrawing (takes a lot of cpu time)
@@ -300,7 +306,9 @@ tests:
 - PD: figure out what "pointer" messages do and where they occur
 - some more mutexes needed for thread safety?
 - buffer resize: flext_base::buffer::Frames(): should we use buffer or system sample rate?
+
 - what about FLEXT_ADDMETHOD_V (for var arg lists) and FLEXT_ADDMETHOD_A (anythings)... nonsense?
+	-> yes, these definitions obscure the meaning of _ as an indication for usage of a message tag
 
 features:
 - abstraction for clock functions

+
+This is a port of Iohannes Zmölnigs "counter" example to the flext paradigm.
+Find the original at http://iem.kug.ac.at/pd/externals-HOWTO/node5.html
+
+The functionality is exactly the same, with one exception:
+flext doesn't support default arguments, hence a message "bound 1" will translate into
+"bound 1 0" in the original example, but won't be recognized with flext.
+This can be easily circumvented by using a method digesting a variable argument list, but
+was omitted for the sake of clearness.
+
+Apart from that you'll notice several differences:
+- with flext, callbacks have to be declared for all registered methods
+- Flext allows the full usage of integer types 
+- there are no real "passive" methods with flext. 
+	These can be emulated by methods, or more flexibly, attributes (see example "attr3")
+- Help symbols can't be defined that freely. This is because in Max/MSP help files always
+	have the name of the object with a suffix .help appended.
+	However with flext, a path to the respective help file may be specified
