I saw the following depreciated features in Oracle APEX 20.1 release notes:

6.1.4 Support for Internet Explorer 11 Deprecated
Support for Internet Explorer (IE) 11 is deprecated.

Starting with release 20.2, only the current and prior major release of Microsoft Edge along with Google Chrome, Mozilla Firefox, Apple Safari will be supported.

Does it mean that Oracle APEX 20.2 will not work correctly in Microsoft IE 11? Does this statement apply only to the APEX builder?...or does it also apply to all applications in workspace? We have a lot of PC's that are still running IE 11.


and we said...

Deprecated means you can still use it, but it is your notification that support will ultimately be removed for it.
Desupported means you can still use it, but we cannot *guarantee* that it will work correctly and if you have a problem, it is extremely unlikely we'd patch it.

There is so much Javascript nowadays that IE 11 does *not* support, I would suspect APEX is just the tip of the iceberg of things that generally just wont work well as time goes on.

Internet Explorer 11

Whether or not upgrading Internet Explorer 11 to Microsoft Edge sometimes may not happen due to the company's IT policies because of existing legacy software that do not support beyond IE 11. For example, I know some companies that have new PC's that run Windows 10 OS but with IE 11 installed - even though Microsoft Edge comes with Windows 10. Also, users cannot install other browsers like Firefox and Chrome.

In the above situation, it means that the Oracle APEX upgrade will end at the 20.1 release and users will lose the opportunity to see all the upcoming exiting features and components of Oracle APEX 20.2 or later. As mentioned above, sometimes it is not up to users to have Microsoft Edge due to IT policies...even though we all know that IE 11 may not compatible with the new Web technologies.

I hope that the Oracle APEX team will, at least, reconsider to include some Modernizr scripts and CSS (for IE 11) in release 20.2 or later so that the upcoming Oracle APEX version will run in IE 11 without any major issue. For example, for Oracle APEX 20.1, all pages and components run fine in IE 11 even though some look may be degraded. For the search item in faceted search, I wrote a custom CSS file so that the magnifier icon and Go button would appear correctly - they overlapped each other when running without my custom CSS in IE 11. This is just some minor work for us in order to show users the exciting new features in each releases.

/* Media Query for Internet Explorer 11 */
@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
.a-FS-filter span.apex-item-icon {
left: 0px;
.a-FS-search span.apex-item-icon {
left: 0px;
padding-left: 12px;

I really hope that all features in Oracle APEX 20.2 will at least work correctly in IE 11 without any major issue.

Thank you!
