libco 0.2.3
	BEWARE: this version depends on python2.2 headers & libs -- this
	dependency will be factored out, but this will take place after copp
	refactoring

	BEWARE (2): The API changed quite a lot from last version...
	
	- very basic python support - with specially-crafted objects it already
	  works - but argument types are limited to int and return value is
	  ignored - for now
	- vastly improved co_exception (cox_*) subsystem: now it supports
	  arbitrary number of cleanup stacks -- and also it underwent preliminary
	  preparations for thread-safedness
	- introduced the concept of object flavours
	- implemented until-now-forced message apparatus as "small" flavour (the
	  destroy flag and method array)
	- implemented the event handling as "default" flavour, operating on top of
	  "small" one
	- re-did the object layout - now we have data pointer instead of embedding
	  header into custom struct's (objects used to be implemented this way in
	  ancient times in then-forming libcwe IIRC)
	- new constructor style - the <objtype>_new function is generated by copp:
	  it will call the flavour's object instantiation and then send "init"
	  message to the object; "bless" is reserved for user initialisation of
	  object (and can take arguments, like the old constructors could)
	- semi-automatic clone support -- you can get cloning by providing
	  "copy_data_from" and "copy_data_deep_from" methods for your object --
	  everything else is taken care of by libco
	- object destruction underwent some re-work -- now there is "delete"
	  message that should be safe to send in any situation; the "destroy2" and
	  "destroy" methods are layered below "delete", where "destroy2" is
	  reserved for flavour implementation and "destroy" is for object
	  implementators disposal (and shalt be called from inside destroy2);
	- co_super now accepts "exit" message (which replaces "destroy" as
	  introduced in 0.2.2)
	- co_super is returned by new co_init function (do NOT use co_super_new --
	  it is broken badly)
	- most important: added more entries to the THANKS file :)

libco 0.2.2
	- improved plugin system, added module loading testcase
	- renamed various __mod_init functions, so their purpose is clearer from
	  the name
	- improved and cleaned up documentation
	- began porting to win32-cygwin
	- destroying co_super cleanly shuts the program down
	- cleanups

libco 0.2.1
	- table-driven default message handler
	- basic adding of methods at runtime
	- simple reflection mechanizm (query for method existence)
	- CO_ATTR ridded of first (redundant) argument

libco 0.2.0
	- now officially standalone project
	- new code preprocessor: copp
		- new ID model
		- new method definition style
		- new message handler
	- improved co_m_v performance - no more COX_TRY block there
	- improved packaging
		- removed intl/
		- upgraded to gettext 0.11.5
		- fixed libltdl problems - ltdl.[hc] is now included in libco if
		  needed
	- prepared to import into platon cvs

libco 0.1.8
	- each error (exception) code can associate error description string
libco 0.1.7
	- separate package (was part of tucniak release)
	- minimal gettext support

---- old versions ----
these come from time, when libco was part of tucniak release; parts unrelated
to libco were deliberately stripped (you can find them in old tucniak-0.1.6
release)

tucniak 0.1.5
	- testsuite works again
	- one more overhaul of libco
	- improved stability
	- throws out-of-memory exceptions on rand () basis :-) (for testing)
tucniak 0.1.4
	- implemented CSEH in libco
	- new object in libco: co_vector (it is barely tested and still unused)
	- internal rearrangings in libco
	- many important bugfixes (in libco and elsewhere)
	- started big reformatting of code
	- disabled testsuite for this release (it is partly out of date)
tucniak 0.1.3
	- regression test suite
	- improved ISO C99 (standard ISO C from year 1999) compatibility
	- libco has new type/action/event id handling
tucniak 0.1.2
	- new library - libco - with new object engine
