The first bit of news is that Microsoft is now planning an Internet Explorer 7 for Windows XP users. Details are scarce, but it looks like they're targeting a June or July beta and a final release around Christmas. (But they say they'll keep doing betas until they get it right, so expect the final release date to slip.)
The second is that SHA-1 has been broken. Cryptogeeks out there are probably already swearing like sailors just from that sentence, and everybody else probably would keep those blank expressions on your face no matter how much explanation I typed, so I won't bother explaining further.
