We're working on an update to Internet Explorer and that update is currently in our testing process and could come out as early as April. However there's no firm date.
Currently that update is in the testing phase and could be released as early as April. But of course, that isn't final.
This is why it takes so long, but that's not to say that if there's an exploit, we won't accelerate testing and get it out there as fast as we can. But if we find problems in the testing phase, it could trigger a restart and cause even more delays.
