For the details with no paywall:

The article says that the guidelines have been updated. Instead of asking if you’re a man that’s had sex with another man in the past 3 months it asks everyone regardless of gender if they’ve had anal sex with a new partner or if they’ve had anal sex with multiple partners in the past 3 months.

This both opens up blood donation to msm in exclusive relationships or who don’t have anal sex and more accurately identifies hiv risk from people who aren’t msm. This is exactly the sort of guidelines we’ve been fighting for for years. This is a major win for both gay rights and blood donation in the US. Now a bunch of people who couldn’t donate before can donate now.
