EOMONTH, EDATE, WORKDAY(.INTL), NETWORKDAYS(.INTL), YEARFRAC, WEEKNUM, the
coupon, bond and T-bill functions, DISC, BIN2DEC, IM* and the other Analysis
ToolPak functions give #VALUE! in Excel 365 for a reference to more than one
cell in a value argument, in dynamic-array and legacy formulas alike, where
GridCraft lifted the range and spilled. Array constants and computed arrays
still lift, and range arguments (holidays, cash flows, schedules) and the
.INTL weekend still take ranges.
FnSpec gains a value_args mask, filled at registration from one table in
lift.rs; call_lifted turns a multi-cell reference at a value position into a
scalar #VALUE! before lifting, so EOMONTH(A1:A3,{1;2}) is a 2x1 array of
#VALUE! as in Excel.

Excel 365 reads a dollar sign before accounting parentheses ($(1,234),
$ (5)) and a percent sign after them ((5)%) as negative numbers when the
text is typed, coerced by arithmetic or passed to VALUE. GridCraft gave
#VALUE! for these.
The parentheses branch no longer recurses: Excel reads only an unsigned
plain number or fraction inside, so (-5), ((5)), ($-5), and dates or
times in parentheses are now #VALUE! as in Excel (they used to give 5
or a negative serial). $5% is #VALUE! too: Excel never combines the
currency and percent signs.

MATCH, XMATCH, VLOOKUP, HLOOKUP, XLOOKUP and LOOKUP compared numbers at
15 significant digits (through compare / compare_numbers), so a computed
key such as =0.1+0.2 (0.30000000000000004) found 0.3. Excel 365 compares
lookup keys exactly in exact, approximate and binary search modes, while
=, SWITCH and the criteria functions (COUNTIF(S), SUMIF(S), AVERAGEIF,
MAXIFS) keep the 15-digit comparison. Observed in Excel via COM with
synthetic values.
lookup_equal now compares numbers with ==, and the lookup searches order
values with lookup_order (exact for numbers, compare otherwise).
compare_numbers and the criteria path are unchanged.

A reference over 16,384 cells was cut to the sheet's used range when it was
read into an array. Next to a full-size operand the two no longer lined up:
SUMPRODUCT(D3:AZ400*B3:B400,(A3:A400=1)*(D1:AZ1=2)) gave #VALUE!,
D3:AZ400*B3:B400 filled with #N/A, and ROWS, COUNTBLANK and --(r="") lost
the blanks past the data. Excel keeps the reference's size.
Bounded references now keep their full shape up to one column's worth of
cells (1,048,576). References that run to the edge of the sheet (A:A,
A2:A1048576, several whole rows) and larger blocks still stop at the used
range, so whole-column formulas stay fast.

Checked against Excel-cached TEXT() results in number- and text-format test workbooks: 226 of 352 TEXT cells mismatched before, 0 after.

AAA exponential smoothing (Hyndman et al. 2008, ETS(A,A,A)) over an evenly
spaced timeline: documented seasonality, data completion and aggregation
arguments, calendar-month date timelines, autocorrelation seasonality
detection, state-space prediction intervals, statistic types 1-8.
Smoothing parameters minimise the in-sample SSE (grid + clamped
Nelder-Mead). XLSX export treats the family's range arguments as
array-taking (no spurious dynamic-array metadata), FORECAST/FORECAST.LINEAR
included.
