This is a hotfix built in May 2014. It contains a few important fixes, and maybe some minor ones which I cannot recall. I did not consider it ready enough for official release at that time, but as I believe it has not made DISE any worse (only better), I am releasing this fix officially right now.
I was made aware that DISE shows malicious content in the news area, and I have verified it for myself. For example, I saw a fake Norwegian news site; someone else saw a fake virus threat and a popup message telling the user to call some phone number.
It's a bit early to say anything conclusive about whether there will actually be a save editor, game trainer, or even other modding tools; however, I would like to take this opportunity to ask you to spare a little time to tell me where your interest lies.
If you haven't heard of Techland's new game Dying Light, you should probably check it out!
