PROTEUS 5.10 README FILE 04/12/00 (SERVICE PACK 1)
==================================================

PROTEUS RELEASE IDENTIFICATION SCHEME
-------------------------------------
Since PROTEUS consists of many separate programs plus a large number
of additional files (e.g. libraries and models), we have decided
to identify different issues of PROTEUS in terms of a version
number and a service pack number. 

The service pack number is indicated at the top of this file. 


SUPPORT VIA THE INTERNET
------------------------
A copy of this file is also available from our web site at:

so that you can see whether you are up to date.

Correspondence related to technical problems should be addressed to

Email is an ideal way to get technical support because you can
attach any related design files to your query.

CHANGES IN 04/12/00 RELEASE (SP1)
---------------------------------

ISIS 5.10.03    Fixed bug in animated simulations where warnings caused simulation to fail.

ARES 5.10.01	Increased component value and other text label limits to match ISIS.

	 	Fixed UAE in about box / statistics.

LICENCE.DLL     Corrected problem with legacy (.REG) key files under Windows NT

SIGGEN.DLL      Added VSM Signal Generator model - check out Lissajous figures sample.


CHANGES IN INITIAL 5.1 RELEASE
------------------------------

ISIS 5.10.01     Added context sensitive help for library parts.

		 When a component is made a into a module parent the child circuit 
		 name is now taken from the device name, rather than the part value. 
		 This allows you to change the value without losing the link to the 
		 child sheet. 

		 A new field on the Make Device dialogue allows you to specify an 
		 external module file to be attached to a component when it is placed. 
  		
                 Added a MODULE marker for defining a hotspot for zooming 
		 into child sheets.

                 Coded for +/- keys to rotate components during place/drag
                 as per ARES.

                 Changed filing code to create a 'last-loaded' file at
                 the start of each editing session.

                 Fixed stack allocation error - cause of some intermittent
                 crashes under Windows 95/98.

                 Fixed bug with 'orphan' child sheets and global device/symbol
                 replacement - a potential cause of corrupt design files.

		 Fixed bug with Read/Write attribute button in the Library Manager,
		 and other bugs related to manipulating library files outside of ISIS
		 whilst it is running.

		 Fixed UAE if copy to clipboard invoked without tag box.


ARES 5.10.00     Zoom/Pan commands and menu layout brought into line with ISIS.

                 Added full context sensitive help.

                 Changed filing code to create a 'last-loaded' file at
                 the start of each editing session.

		 Added TAB key shortcut to Icon Panel. This toggles between
		 the current mode and the previous mode.

                 Fixed stack allocation error - cause of some intermittent
                 crashes under Windows 95/98.

                 Fixed some internal-exception bugs in auto-router.

		 Fixed divide by zero with very large work area sizes.

		
PROSPICE 5.10.02 Added Transient Tab to SPICE options, for explicit
  		 control for max timestep, mixed mode timing accuracy, etc.

		 Added support for pin and callback handler functions to VSM API.

		 Fixed bugs in DSWITCH primitive when operating in mixed mode.

                 Fixed bug in DC Sweeps with negative sweep parameter.

		 Fixed bug in DC operating point analysis / multimeter mode.


MCS8051 Model    Added debug monitor support for Keil UV2.

                 Added online documentation.

		 Fixed UAE if used in graph based simulations.


PIC1684 Model    Added online documentation.

		 Added support for obsolete instructions.

                 Fixed missing ITFMOD properties in library parts so that
                 model now works correctly in mixed mode circuits.
	
		 Fixed UAE if used in graph based simulations.
		
 	         Fixed bug with interrupt wake up from sleep mode.




CHANGES IN RELEASE 5.03
-----------------------

ARES 4.85.01	Fixes intermittent problems with printing and CADCAM output.
