macro-op fusion of LUI/JALR and AUIPC/JALR pairs.

\item Corrected the description of the FNMADD.{\em fmt} and FNMSUB.{\em fmt}
instructions, which had suggested the incorrect sign of a zero result.

\item Specified behavior of narrower ($<$FLEN) floating-point values held in
wider {\tt f} registers using NaN-boxing model.
\item Defined the exception behavior of FMA($\infty$, 0, qNaN).
-\item A draft proposal of the V vector instruction set extension.
-\item An expanded pseudoinstruction listing.
-\item A new table of control and status register (CSR) mappings.
\item Added note indicating that the P extension might be reworked
into an integer packed-SIMD proposal for fixed-point operations
using the integer registers.
+\item A draft proposal of the V vector instruction set extension.
+\item An early draft proposal of the N user-level traps extension.
+\item An expanded pseudoinstruction listing.
\item Removal of the calling convention chapter, which has been superseded by
the RISC-V ELF psABI Specification~\cite{riscv-elf-psabi}.
