It still handles them poorly by default. You can do things like edit .gitattributes to say that e.g. a *.binary file should be treated specially, but Git's still not a good system for e.g. archiving HD video.
Some of this can be fixed, but a lot of it is probably not going to change. When you git-add something it has to checksum the old data + new data. That's going to be a pretty expensive operation when you have 50TB of data.
There's no DVCS that I'm aware of that handles large binary files as well as say Perforce or Subversion.
