<H3>Release 3e (2018 January)</H3>
<UL>
<LI>
Changed the default numeric code for optional rounding mode <CODE>odd</CODE>
(round to odd, also known as <EM>jamming</EM>) from 5 to 6.
<LI>
Modified the behavior of rounding mode <CODE>odd</CODE> when rounding to an
integer value (either conversion to an integer format or a
&lsquo;<CODE>roundToInt</CODE>&rsquo; function).
Previously, for those cases only, rounding mode <CODE>odd</CODE> acted the same
as rounding to minimum magnitude.
Now all operations are rounded consistently.
<LI>
Fixed some errors in the specialization code modeling Intel x86 floating-point,
specifically the integers returned on invalid operations and the propagation of
NaN payloads in a few rare cases.
<LI>
Added specialization code modeling ARM floating-point, conforming to VFPv2 or
later.

Fixed a minor bug whereby function <CODE>f16_to_ui64</CODE> might return a
different integer than expected in the case that the floating-point operand is
negative.
