DevExtreme and related products: End of support for Internet Explorer 11

After a lot of internal discussions over the past year, we have come to the decision to end support for Internet Explorer 11 (IE 11) with the next major update of DevExtreme and all related or dependent products. This will be version v21.2, which is due October/November 2021.

The following subsets of the DevExpress product line will be affected:

DevExtreme v21.2+, the entire product line:

• DevExtreme for JQuery
• DevExtreme for Angular
• DevExtreme for React
• DevExtreme for Vue

XAF ASP.NET Web Forms UI v21.2+, especially:

• Maps Module
• Dashboards Module
• Office Module
• Reports V2 Module
• ShowViewStrategyBase.ShowMessage (this uses dxToast internally)

ASP.NET components v21.2+, notably:

• All ASP.NET Core components that are based on client-side DevExtreme components
• All ASP.NET MVC components that are based on client-side DevExtreme components

Dashboards v21.2+, pretty much across the board with regard to the web:

• Dashboard for Web Forms
• Dashboard for MVC
• Dashboard for ASP.NET Core
• Dashboard for Angular
• Dashboard for React
• Dashboard for Vue
• Dashboard for JavaScript

Reports v21.2+, primarily:

• Web Document Viewer
• Web Report Designer
• Web Query Builder

I emphasize that the decision to end IE 11 support was not made easily – we know that some of our customers do rely on IE 11 and will be adversely affected by this decision. Unfortunately, we can no longer delay the inevitable.  At present, we are forced to maintain a good deal of IE 11 specific code (be it HTML, CSS, or JavaScript), let alone considering the amount of testing particular to IE 11 we have to do before releasing a new version. By ending this support, we will be better able to focus our energies on the modern web and maximize the long-term potential of our JavaScript product line.

For those of you who cannot abandon IE 11 (and are understandably dismayed by this announcement), please remember that you can continue to use v21.1 as long as necessary.

Before ending, I’d like to point to a couple of interesting facts that helped us make this decision.

Microsoft 365 Apps Say Farewell to Internet Explorer 11: As of August 17, 2021, Microsoft 365 apps will no longer support Internet Explorer 11.

“Customers have been using IE 11 since 2013 when the online environment was much less sophisticated than the landscape today. Since then, open web standards and newer browsers—like the new Microsoft Edge—have enabled better, more innovative online experiences.”

Worldwide Desktop Browser Usage Statistics: At present, IE 11 accounts for less than 3% of desktop market share (which drops to less than 0.2% when mobile browsers are included).

Your Feedback Matters

While we feel that we cannot delay this decision any longer, we do want to hear from those who will be affected by our decision to end IE 11 support. Either post your comments below, or submit a support ticket via the DevExpress Support Center.
