Changes Introduced != "release notes"

Please note, this document is intended to "go beyond" the basic release notes and give more details where needed. Such as Release notes may say "new feature - added single page view to WDV"  where the Changes Introduced will tell you more useful information such as "to enable this feature you need to set the singlepage config option to true here..."

NEW Features

.NET Core

In 11.4 we have begun shipping DLLs marked as "5.0" ( C:\Program Files (x86)\Atalasoft\DotImage 11.4\bin\5.0 )

These are DLLs for targeting .NET 5 / .NET 6 (Also known as .NET core) NOTE that we do not support .NET Core 3.1 or older with these dlls)

There will be more to come here, please check back in this space soon for links to articles and/or sample apps.


These are important changes but ones that don't directly require code changes or other large rewrites

Documentation / Help Files

In previous versions, the ApiReference.chm and DevelopersGuide.pdf were installed to a folder named help to:

C:\Program Files (x86)\Atalasoft\DotImage 11.x\Help\

These are larger changes that may require code changes/ rewrites or where features/support was dropped or removed

DLL Restructuring

In 11.4 you may notice some DLLs are "missing" versus previous versions. This is by design.

We distribute our SDK in sets based on Framework
our dlls for targeting .NET Framework 3.5 are in
C:\Program Files (x86)\Atalasoft\DotImage 11.4\bin\3.5

Our DLLs for targeting .NET Framework 4.5.2 through 4.8.x are in
C:\Program Files (x86)\Atalasoft\DotImage 11.4\bin\4.5.2

Our DLLs for .NET 5 and .NET 6 are in
C:\Program Files (x86)\Atalasoft\DotImage 11.4\bin\5.0

for the 5.0 distributions of DLLs, we've removed

These components may also be removed for the .NET Framework versions in future releases (support for Ink annotations and MVC legacy web controls are deprecated as are the Legacy web controls - new application development for web based projects should exclusively use our WebDocumentViewer (modern HTML5) web controls.

Dropped Support

MS Internet Explorer (11 and older), and non-chromium versions of MS Edge

We can no longer officially support MS IE 11 or older, and we can not support MS Edge if you're using a non-Chromium based version.

Your legacy apps MAY continue to work with these outdated browsers and if so that's OK but if you report a bug/issue with our web controls if must be replicible in Current versions of Google Chrome, MS Edge (Chromium based), and/or FireFox; or in the current Safari release for MACOS machines.

MACOS Mojave and older dropped

This applies to the Web Capture client-side component. The installable MACOS package that clients using pages with WebCapture need to install. The package no longer supports MACOS Mojave and older

INK Annotation Support Removed

MS Ink annotation support is being removed. Its not part of the new .NET 5 dlls and may be removed from 3.5 and4.5.2 dlls in future. This was a seldom used feature as our Freehand annotations work very well to handle what they provided without needing a whole separate MS infrastructure
