Sorry. In the old spec(version 0.41), nanboxing is not totally disabled, but "NaN-boxing is limited to |XLEN| bits, not |FLEN| bits". Taking misa.mxl into acount, if misa.mxl is RV32, and maximum is RV64, this should be sign-extended. Is there any other new update for nanboxing  to the spec?

Yes, in 1.0.0-rc, it's all gone.
