IE11 Support Is Ending!!!

As you know, Microsoft has officially announced the end of support for IE11, they have introduced Edge as a replacement browser which is based on Google Chrome.  In line with this change, Hornbill are looking to drop support from our development workflows for IE11 also.  

There is an ever growing list of improvements, enhancements and even defect fixes that are currently sitting in our backlog classified as "Can'd Do This Because of IE11", and just like previous Microsoft browsers our ability to maintain compatibility is both diminishing and becoming a very material progress constraint. 

Currently we have a friendly and dismissible warning in the UI that is reminding for users on IE11 that support is being dropped in line with Microsoft which is around the June 2022 timeframe.  However, over the coming weeks we are going to be making that message more prominent and imposing. Statistically, less than 1% of our total network traffic is originating from IE11, coming from around 11 customer organisations, so the use is actually very small, none the less despite the warnings so far, that usage has not really changed.  

So starting with the release of the new Admin UI, future developments are very likely to simply not work in IE11 as we are not consoling the IE11 edge cases, or adding a bunch of polyfill's just to plug the gaps in IE, we are taking advantage of the better security and more modern functionality that the newer, more modern browsers bring to the table. 

Right now this only apply to the User app (live.hornbill.com) but will very soon also apply to the other portals too, but please be aware that this will all change during the course of H1/22 as our codebase transitions out of supporting the now ancient IE11 technology. 

If you have IE11 users accessing Hornbill, please do what you can to move them to a more modern alternative. 

Thanks,

Gerry

In the next Hornbill update, there will be a more prominent and un-dismiss-able notice presented in the user application on the top navigation bar, this will be seen by any user that is still using IE11 to serve as a reminder that we are ending support for IE11.  These is also a link in this notice that explains more about the change.  I am told by our engineering team that in order to start to implement some of our backlog we need use some of the more modern browser features that are not supported in IE11 at all. So while we will not set out intentionally to stop IE11 working, its very likely that parts of Hornbill will become broken if you are using IE11, and when that does occur, we will have no possible way of fixing those problems as the breakages will be caused by using browser features which simply do not exist in IE11 

Maintaining compatibility with IE11 has been one of the major contributing factors to our inability to effect change, we currently have quite a lot of "workarounds, polyfills and legacy code" just to keep IE11 working, by dropping support for IE11 we can immediately set to work in modernising these code areas and paving the way to make significant UI/UX improvements.  We are doing our best to warn you in advance but this change is coming fast...
