Version 4.0 

-	ActiveX has been digitally signed by certificate from Thawte.
-	Image processing functions (deskew, rotation) have been added.
-	ActiveX now allows to create a custom progress indicator of image scan.
-	New properties (deviceOnline, showIndicators, jobControl) have been added.
-	The noiseLevelInBlankImage property has been deleted.
-	Bug in the httpResponseString property has been fixed.
-	Examples have been updated.

Version 3.7.1 

-	Image uploading process has been modified for compatibility with IIS 6 and 7 servers.

Version 3.7 

-	This version of ActiveX is fully compatible with Windows Vista.
-	From this version the fileName property can be used only at runtime.

Version 3.6.5 

-	Ability to set a cookie in image uploading session has been added. This can be useful if you must authenticate with the Lotus Domino server.

Version 3.6 

-	Now it's possible to use File transfer mode for acquiring images. This transfer mode can greatly increase speed of scanning if high-speed scanner is used because scanned images will be saved directly to a disk.
-	Minimal and maximal values for brightness and contrast was determined not correctly for some models of Canon scanners. Now this bug is fixed.

Version 3.5 

-	Export table of ActiveX Control has been changed. In most cases it's necessary to recompile programs which are using the ActiveX Control.
-	Algorithm of scan process has been optimized for compatibility with Xerox and Visioneer scanners.
-	Algorithms of noise removal, border detection and detection of blank page have been optimized.
-	Examples for VB.NET, C#, VB, VC++, Delphi, C++ Builder have been modified.

Version 3.3 

-	Algorithm of FTP transfer has been modified for compatibility with Pure-FTP and IIS 6.0 FTP servers.

Version 3.2 

-	Noise removal (despeckle) algorithm was optimized. Removing noise from images now is possible for all types of images.
-	Border detection of image now is possible for all types of images.
-	Format of TIFF images with bit depth more than 8 bit (16 bit gray images and 48 bit color images) has been changed. New images now can be opened in Adobe Photoshop.
-	GetImageAsHDIB method has been added. This method allows to get image as device-independent bitmap (DIB).
-	DeleteImage method has been added. This method allows to remove selected image from internal images buffer.
-	Algorithm of IsBlankImage method has been updated.

Version 3.1 

-	The ability to detect borders for color images has been deleted. This algorithm will be revised and added in next version of ActiveX.
-	The bug in work of the AcquireModal method has been corrected.
-	The bug in work of ActiveX with Canon's digital cameras has been corrected.
-	Example for JavaScript has been created, which illustrates how to work with automatic documents feeder.

Version 3.0 

-	The AcquireModal method has been added. This allows to acquire images without usage of the PostScan event.
-	Ability to acquire images by the Memory Transfer mode has been added. This allows to acquire 16-bit gray images and 48-bit color images and save them to a TIFF files.
-	The border detection algorithm has been added.
-	The despeckle algorithm has been added.
-	Ability to rotate images has been added.
-	The httpResponseCode property has been added. This property allows to get response code from HTTP server.
-	Example for C# has been created, which illustrates how to save acquired image to table of MS SQL server.
-	Example for IBM Object Rexx has been modified.
