Every news org seems to be running with "Earth-like" (as opposed to "Earth-sized" or its ilk) in their headlines, which implies something really important that we really don't know yet.
It's in the Goldilocks zone... it has Earth-like temperature. And with how abundant water has turned out to be, probably oceans of liquid water.
No, it has the potential for Earth-like temperatures. Nothing more is known than that. Venus and Mars are in the habitable zone but aren't hospitable to life and don't have Earth-like temperatures. There's also a strong chance it's tidally locked, which would not allow for Earth-like temperatures for the vast majority of the planet.
