VERSION 1.5.1:

  Updates to misc. throw() specification errors that some compilers caught
  Small update to Win32 project files
	
VERSION 1.5.0:

  Simplified templates (Executors, etc) avoids multiple definition error when linking
  Timer error fixed  
  Misc bugs (minor) in Win32 implementation repaired.
  Moved old Mutex to PlainMutex, replace with a Mutex that can be interrupted
  which is more useful in general. For most cases the FastMutexes can be used in
  thier place when the user desires no interruption

  Added a couple contributed header for disabling warning with VC, you
  can use them to disable warnings in general for visual c's 
  handling of stl symbols. (optional - vc specific)
	
	
VERSION 1.4.4:

  Fixed bad throw clauses in the examples that gcc 3.0 choked on.
  Updated templates to include a default template with a specialzation for
  daemon threads, resolves alot of problems with compilers generating the 
  code for those tempalte multiple times.
	
VERSION 1.4.4:

  Fixed bad throw clauses in the examples that gcc 3.0 choked on.
  Fixed typo with #ifndef/#define in Win32_FastRecursiveMutex.h
  Corrected documentation for AutoPtr 
  Improved the GNU autoconf/automake builds (again). 
  - Added '--enable-examples' option to configuration
  - Updated configuration files to with libtool 1.4, the older ltconfig
    cause some problems with some systems.
  - Fixed the 'distcheck' rule. 
	
VERSION 1.4.3:	

  Moved the headers to a more standandard directory, everyone asked me
  for it.
	
  Fixed a timeout oversight the ThreadImpl.
  - Blocking with a timeout was not responding correctly.
  - Added one more thread state, JOINING. Prevents multiple joins,
    while allowing the rest of the logic to function correctly.
	
  Improved the GNU autoconf/automake builds. 
  - Added 'make rpm'
  - Added 'make docs'
  - Fixed 'make dist'; previously, I had intended ppl only to use 
    'make' & and 'make install'
  - You learn more about autoconf every time you have to update this
    stuff. Good tool, big learning curve :)
	
VERSION 1.4.2:
	
  Fixed a typo in the AutoPtr class template
	
VERSION 1.4.1:

  Added a pthread.m4 macro, Updaed other misc build files
  Fixed some errors with the throw clauses on Worker & InheritableThreadLocal
  Fixed the Timer class which has been overlooked since the improvements
  to managing static object were made
	
VERSION 1.4.0:

  Make more distinct the change in kill() and other behavoir in the  
  last few version.
	
VERSION 1.3.5:

  Enchanced the ThreadLocal variables.
  Updated & simplified FastMutexs. 
   
VERSION 1.3.4:

	Revised the implementation classes a bit.
	Revised the Worker class so it can be canceled/killed
	without having effects on executing tasks.
	Added new/better support for killing threads
	Added more comments to the implementation classes
	
VERSION 1.3.3:

	classes
	
VERSION 1.3.1:

	Updated errors in Win32 build files
	Updated the Observable template to be friendly with more compilers
	
VERSION 1.3.0:
	
	Updated compilation bug in Win32 dynamic build. That build will
	compiler correctly again and the dll version will have the same
	behavior as all other builds, making things more predictable.

	Updated executor classes to make room for reusable task objects
	and a little more flexibility

	
VERSION 1.2.4:

	Fixed an oversight in the documentation configuration file and
	the Timer.cxx, I released 1.2.3 just a little too hastily :)
	
VERSION 1.2.3:

	Updated WIN32 & POSIX Thread management
	Bug fix in WIN32 thread wait() routines
	Added daemon thread support for static objects
	
VERSION 1.2.2:

	objects. Much faster, and reduced contention.

	Updated all classes using the Cancalation interface
	
VERSION 1.1.3:

	Spell checked the documents (tedius)

	Bug fix in Barrier.cxx

	Updated Documentation (noticable change)
	Updated ThreadLocal classes
	Updated ThreadImpl classes

	Miscellaneuos updates to make some class definitions for
	formal (addition of needed throw() clauses, etc)

	Had some testing on Tru64 unix that was posative
	
VERSION 1.1.2:
	
	Bug fixes in the Thread class. I had overlooked that reference Thread
 	objects (eg from Thread::current()) were deleting the thread implementations
	mistakenly

	Added a very usful Observable template
	Added timer classes

	There might be several other bug fixes I forgot to document completely, most
	of this work was done because I was using Zthreads in creating another application
	so I just fixed and enhanced the library as was appropriate

	Also, there are now static & shared library builds for all supported platforms

VERSION 1.1.1:

	StaticSingletion template was added

	This is another build update, the library will now install
 	so it is much easier to use way.

	Versioned shared libraries were also added using libtool. You
        can link against the shared library, or your can link against
        the .la file in build directory

	A 'zthread-config' script was also added to help other write 
	configure scripts that look for various versions of the library

 
        Some very useful information for the autoconf tools that helped
        can be found at the following URL

VERSION 1.1.0-2:
	
	This release basically include some packaging fixes. 
	The autoconf scripts generate Makefiles now that link with
	-pthread instead of -lpthread on FreeBSD

VERSION 1.1.0-1:

	Someone used BoundsChecker and caught a small memory leak
	that was fixed. There was an '==' where a '!=' was needed.
	I wish I could include thier name, but when my university
	email account was closed it ate all my old email so I ended up
	losing that corespondance

VERSION 1.1.0:

	This release has many changes.

	For one, I have tightened up the exception classes. This makes
	the exceptions easier to handle, the code in general, easer to
	read. The exceptions can carry useful information now where as
	before they were just objects of different types being thrown

	Some exceptions have been removed because they were reduntant

	Thread priorites have been remove because I don't feel there is
	a good reason to have them. Thread priorities act differently 
	across all machines, and my goal in creating this library was
	to build a usable archtechure for controlled predicatable 
	multithreading. Thread priorites don't fit in.

	Runnable objects return void now. There is no need to a runnable
	object to return a value. I felt this was an uneeded complexity.
	Enough has been provided in this library to have the results of	
	task run by other threads commincated in a number of better ways
	than a return value.

	A ThreadLocal object was added to provided access to local thread
	storage. This is very much like Java' ThreadLocal object.

	All of the basic synchronization objects have been improved. Several
	new ones have been added whose purposes are straitforward.

	The implementation of the this package was revised and refactored.
	There is no longer a need for a SyncFactory, and a whole layer of 
	virtual function calls was also removed. This increased the speed
	and elegance of the code. The ThreadImpl classes were also better
	encapsulated.

	The Thread class is now extendable and you can use pretty much just
	a like a Java Thread.

	The queue classes have all been updated. I think there may even
	be one more than before. 

	I have refined these queue classes as the executor pattern I was
	using improved. I added a 'Cancelable' interface to these objects
	hopefully I will have the time to write a small paper on the pattern
	to fully explain it. Most of the executor pattern I improved in 
	java and I just recently updated zthreads to reflect this. I may
	relese a java supplement to the library shortly. I find that java 
	is very useful when expirementing with different types of patterns.
