We are going to drop support for Internet Explorer 9

We have been one of the last jazzy Web apps out there that was still running on Internet Explorer 9, but that’s going to change: with our next release, due in a month or so, we will be asking Internet Explorer users to upgrade to IE10 or later.

The main reason for this change is that all “modern” browsers — and IE9 qualifies as “modern” only when it stands next to IE8 — do a lot of work within the browser itself that Kerika currently does: stuff like managing and manipulating the DOM structure of the Kerika application.

This means that the Kerika client-application — the bit that you actually see and use in a browser — is unnecessarily complicated, and somewhat slower, than it needs to be, because we are doing some work that IE10+, Chrome, Firefox and Safari all do within the browser itself.

Dropping support for IE9 will enable us to provide a faster user experience, with less complexity in the code.
