Crypto Patents and PGP Lib 3.0?

I haven't seen any mention lately of the mythical PGP Lib 3.0. The last I recall hearing was that it was waiting to be release this month when certain patents expired. Does anyone know which patents or algorithms those are? I know that D-H expired back in April, but what about RSA and any other "basic" algorithms? -- Allan Bailey Excite, Inc. (Austin)
