07/15/95 Release 2.2
~~~~~~~~~~~~~~~~~~~~	

This is the last release with Tk 3.6. Next release will integrate Tk 4.0

	- Bug corrections 
	- Changing Makefiles and configure files for better dynamic loading
	  integration. 
	- Adding support for BLT-1.7. This library can be loaded dynamically
	  on system which support it
	- New option which permit to change the initial amount of cells
	- Uses really LESS memory.
	- New GC. Now  we have a set of heaps and a new heap is allocated as
	  soon as the global space is "nearly" filled.
	- SLIB support (just type (require "slib") and after that process as
	  indicated in SLIB documentation
	- Integration of the Suresh Srinivas STk-wtour demo.
	- Adding support for Text in STklos: Definition of the <Text> class
	  (and companion <Text-tag> class).
	- call/cc is now tail recursive. (Alas, methods and dynamic-wind are
	  not yet tail recursive).
	- Better support for autoloading files
	- Adding support for an exec function a` la Tcl (i.e. execute of a 
	  unix process and keep its output in a Scheme string)
	- General run-process for running Unix process were std{in,out,err} 
	  can be redirected in files or in pipes.
	- Some code has been rewritten to ease STk porting
	- Adding support for regular expression pattern matching and
	  replacement 
	- There is now a light interpreter, called snow (for Scheme
	  NO Window); this is in fact the STk interpreter without Tk support. 
	  This interpreter is an independant executable. It can be called 
	  with the `snow' shell-script or by unsetting the DISPLAY variable.
	- New organisation of intalled file to permit co-existence of
	  several version of STk or multi-architecture file sharing
	- Dynamic loading support for NetBSD-1.0 
	- Dynamic loading support for HP
	- Dynamic loading and dump support for FreeBsd.
	- Dynamic loading for Linux (using ELF format or the DLD package)
	- A mini interface builder (very simplistic, but usable)
	- New contributions: A true Tetris game, a 8 queens simulation and 
	  a demo of composite widgets.
	- Every exported identifier now starts with the string "STk_" to
	  avoid name clashes when embedding the interpreter in an application.
	- BSD sockets support 	
	- Better integration with Emacs
	- AMIB (A Mini Interface Builder) 
	- A lot of improvement in STklos
	- .....

==============================================================================
??/??/?? Release 2.1
~~~~~~~~~~~~~~~~~~~~	

This is a major release version. 
    
	- STklos (the object layer) is now written in C. It is more than 150
	  times faster than before and it uses less memory (~ 1/100)!!!!
	- Improvement of STklos 
	- STklos classes have been written for all the Tk library widgets
	- Composites widgets can be easily defined in STklos. Access to those
	  widgets is identical to C written one.
	- bindings can be now true lambda expression with their own
	  environment (rather than list which are evaluated in the global 
	  environment).
	- Hash tables have been added.	
	- Small constants are coded on a pointer rather than a cell
    	- Support for dynamic loading on SunOs (4 and 5). Dynamic loading
      	  uses shared objects (it should work also on OSF1)
	- Dump creates now smaller images.
	- Modification of configure and Makefiles to correct of a lot 
	  of installation problems.
	- Runs on Solaris 2.3
	- Bugs corrections 
	- Some modification to the error notifier
	- Support of dynamic loading of shared objects on Solaris 1 & 2 (it
	  should work also on OSF1).
	- ...

94/01/03 Release 2.0
~~~~~~~~~~~~~~~~~~~~

    STk 2.0 contains a completly rewritten Scheme interpreter. This new
    interpreter is
            - R4RS
            - faster than previous release (~ 3 or 4 times)
            - less bugged (I hope :-) )
            - implements integers (32 bits and bignum) and floats
            - cleaner with macros 
    
    This version contains also a prototype of a graphical inspector which
    permits to see/modify a variable value. For widgets variables it permits
    to modify interactively their behaviour. However, it doesn't yet contain
    a C rewritting of the object layer as it was planned. This will be done
    in a (probably the) next release.
