MS IE 11 support had been added in JExplorer 2.7 right after MS IE 11 release (April–May 2014). Several months later a few of our customers informed us that they have issues such as native crashes, freezing and Fail Fast exceptions in Java and JExplorer32 processes with MS IE 8-11 with the latest updates.
We figured out that these issues are reproducible only with the latest MS IE 8-11 updates starting from 11.0.10 (Summer 2014). We analyzed crash dump files and function call stacks and figured out that problems were caused by regression issues in MS IE 8-11 updates. Microsoft confirmed that their latest updates are causing similar issues and they started working on fixing these problems. Microsoft engineers do not give exact estimates on the expected fix time, but we anticipate that it may take months before a new update of IE 11 goes public.
While working with Microsoft on the issues, we figured out that it can be avoided by re-designing and re-implementing the way JExplorer integrates with IE. We created a prototype with the new design and got a confirmation that all issues introduced in the latest MS IE 11 updates can be worked around on our end.
So, right now we are working on the next JExplorer version that would be compatible with the latest MS IE 8-11 updates. It will be a major rework with a much more reliable implementation of our library, which will include several necessary changes in the public API. We will do our best to make the new API compatible with JExplorer 2.7 version as much as possible, but we cannot make it 100% compatible.
Update:
It's compatible with all latest MS IE 8-11 updates.
