********************************************

	[+] - stands for new features.		
	[-] - stands for known bugs.
	[*] - stands for fixed bugs.
	
********************************************
Version 3.05
Sunday, October 31, 2004

[+] Shareware Nag Screen updated...
    To let you think about registration
    benefits a little bit more.
    Thanks to Bill from USA :)    

[+] Error report is reverted, to make it
    easier to compile your code and find
    possible syntax errors.

[*] DIV instruction error:

	 MOV DX, 0FFFEh
	 MOV AX, 00001h   
	 MOV BX, 0FFFFh
	 DIV BX

    Is totaly fixed.
    Thanks to Mehrdad University of 
    Amir Kabir (Poly Technic) of Tehran - Iran :)

 [*] The External Memory Viewer window caused
     a very long "Reload"... Now you have to
     press "Refresh" button, because otherwise
     it works very slow even on Pentium 10GHz.
     Thanks to Y.W. Lee from Hong Kong :)
     This problem fixed is also fixed.
     
********************************************
Version 3.04

[*] Editor highlight for SCASB and SCASW 
    instructions works from now on.    
    Thanks to Marco from Spain :)

[*] Declaring STACK segment before DATA
    segment for EXE file, caused memory
    access problems. Bug fixed.
    Thanks to Y.W. Lee from Hong Kong, 
       and Egman from China :)

********************************************
Version 2.09
Friday, December 27, 2002

 [+] External add-on devices can be attached
     to Emu8086! See "simple_io.asm" in
     samples. Other programmers can write
     their own devices in Visual Basic or
     any other language (VC++), check

 [+] When double clicking over the value
     in STACK window "Extended Value Viewer"
     is opened.

     minimized when emulator is shown.

 [*] INT 15h / 86h works correctly!
     Thanks to Teerapon Jungwiwattanapor!

 [+] Interface of Emu8086 can be translated
     to any other language (German, French,
     Italian, Spanish, etc...). For more
     information check inside "Translate"
     folder.

 [+] More samples added:
 
      matrix.asm - matrix transpose sample.
      
      palindrome.asm - checks if string
                       is a palindrome.
                       
      ToBin.asm - prints out binary
                  equivalent of a decimal
                  number.

 [*] Disposition for Flags window is
     restored more precisely when it is
     at the right edge of the screen.     

 [*] Regression found and fixed:
     compiler wasn't adding variable
     offset when calculating effective
     address:
             MOV a[bx][si], 7
             a DB 1,2,3,4,5

********************************************
Version 2.06
Thursday, November 21, 2002

 [*] DAA and DAS instructions correctly
     adjust the result (in all situations)
     and required flags are set.
     Thanks to Jacob Feindt!

     memory. Accessible from "View" menu
     of the emulator as "External Memory
     Viewer".

 [+] When a register or variable changes
     (while single-stepping), it is
     highlighted. It may help the user
     notice that something has changed.

 [+] User can set custom output directory.
     Accessible from "Compile" menu.

 [+] Decimal immediate values may have "d"
     suffix, for example: MOV CX, 10000d

********************************************
Version 2.04
Saturday, August 24, 2002

 [+] New sample added:
        "print_hex_digit.asm"

 [*] Options to set default colors for
     User Screen are improved.

 [*] "Debug Log" is unloaded correctly
     when Emulator window is closed.

 [*] Compiler supports:
       MOV AX, [BP]
     (even without displacement).

 [*] Tab indexes corrected for controls on
     emulator window.

********************************************
Version 2.02
Thursday, August 08, 2002

 [+] Documentation updated.

 [+] For COM file CX register is set
     to file size in bytes.
     For EXE file CX register is set
     to file size without EXE header (200h).

 [+] Made possible to Drag & Drop files
     from Windows Explorer into the main
     window (area below the "About" button),
     and into the emulator window (area 
     between "Memory" and "Disassemble"
     buttons).

********************************************
Version 2.01
Monday, August 05, 2002

 [+] Documentation updated.
      "MASM / TASM compatibility" section
      added to "Emu8086 reference".

 [+] Cancel button added to "Choose

 [+] Message Box is automatically hidden
     on reload when it has one of the
     following messages:
        "System halted!"
        "PROGRAM TERMINATED!"

 [*] This code gives more reasonable
     error messages:
	MOV AX, 0
	MOV CX, 5
	m1: INC AX
	LOOP m1        ; not a real error!
	MOV AL, 0FFFFh ; real error is here.
     (see also "Compiling Assembly Code"

********************************************
Version 2.00
Saturday, August 03, 2002

     automatically hidden when emulator
     window is closed.

 [*] "Lexical Flag Analyzer" supports
      standard emulator hot keys:
       F8           - single step.
       Shift + F8   - step over.
       Ctrl + F8    - run until cursor.
       F9           - run.
       F7           - current instruction.

********************************************
Version 1.32
Friday, August 02, 2002

 [*] It is no longer required to un-install
     previous version of Emu8086 before
     installing new version.
     Thanks to Darrell Collins.

 [*] Un-install of previous version does not
     reset options for current version of
     Emu8086.

 [*] Hexadecimal and Octal values are
     treated as unsigned, huge decimal
     numbers are not converted to singed
     values. Compiler reports expected
     overflow error messages for:
      MOV BL, 0FFFFh
      MOV BL, 177777o
      MOV BL, 65523

 [*] Emulator does not reset its options to
     default after it is closed and then
     re-opened.

 [*] Backup ".~asm" files are saved with
     original extension of an executable
     file, to prevent conflicts.

 [*] "MyBuild" folder is automatically
     re-created even if manually deleted on
     runtime. Required for "Compile and
     Emulate" button to work properly.     

 [*] LOOP instruction is disassembled
     correctly. Previously it was decoded
     as LOOPNE.

********************************************
Version 1.31
Tuesday, July 30, 2002

 [+] "Lexical Flag Analyzer" added to
      "View" menu of the emulator.
      (see "4_sample.asm" in Samples).

 [+] Default "step delay" is set to 200 ms.

 [*] Documentation flaws corrected.

 [*] Assembler recognizes data types better,
     and generates correct machine code
     (even without 'b.' or 'w.').

 [*] Regression found and fixed:
     SHL BX, CL
     and other shift-rotate commands
     were not assembled when second operand
     is CL.

 [*] Undefined data was set to AX by the
     following code:
     		MOV CL, 0
     		MOV AX, 5
		SHL AX, CL
      (AX should be unchanged). Fixed!
 
 [*] Bizarre resize of Editor Window
     (to the minimum) caused GPF under
     Windows XP. Fixed!

 [*] This code caused overflow:
      MOV AL, 251
      MOV BL, 254
      MUL BL
                   Fixed!

 [*] Incorrect result was calculated by:
      MOV AX, -12
      MOV BL, -2
      IDIV BL
                   Fixed!

 [+] "Debug Log" shows next instruction
     that is going to be executed when
     it is opened.

********************************************
Version 1.30
Sunday, July 28, 2002

 [*] Version number added to default install
     path, to avoid conflicts with previous
     installations. Thanks to Starman!

 [+] Variable View improved, it is possible
     to view arrays and strings while
     your program is executing.
     See "Variables" in Tutorials.

 [+] Full path to source file is included
     in editor's caption.

 [+] Support for BIN files improved.

 [+] Stack window is less flickering.

 [+] Separate "View" menu added to emulator,
     it allows to see Stack, Variables,
     Flags, User Screen, ALU and etc...

********************************************
Version 1.29
Wednesday, July 24, 2002

 [+] New sample that prints out the result
     with floating point added to Samples
     folder: "float.asm".

 [*] Disassembler updated! Some relative
     jumps were not decoded correctly.

 [+] Option to browse "MyBuild" folder or
     load in emulator after compilation.

 [+] Shortcut to Emu8086 is added to
     "SendTo" folder automatically, this
     allows to load any ASM or Executable
     files directly without changing your
     current Windows settings.

 [*] Regression found and fixed:
     MOV AL, [SI] + 00102h
     was not compiled properly!
     Thanks to Donald?!

 [*] Segment prefixes are not treated as
     labels on pre-compile.

 [+] "CALL immediate" is supported.
