There have been some changes to the canon, yes, but Oracle is still around - I read about her in Birds of Prey.
There's also Rene' Montoya, who was outted in the Gotham Central story 'Half a Life.' A few other GLBT characters I'm a bit tired to put a name to - Alan Scott's son, Kate Spencer's co-worker, Maggie Sawyer, Mikal Tomas, John Constantine (dunno if he really counts, since he's sort of in his own corner) and Wonder Woman (dunno if she counts 'cause I might be reading a bit much into a few comments.)
Not a lot, but better than none. Right?
