Chart sheets (a sheet that holds one chart; Move Chart > New sheet, F11) were
skipped on open, and their chart sheet, drawing, chart, style and colour parts
were dropped with them because the pass-through treats those kinds as content
GridCraft rewrites. Saving a workbook lost every chart sheet.
They are now kept as they were: the <sheet> entry (name, visibility and its
place among the worksheets), the chartsheet part and everything behind it,
byte for byte, written back in place. The workbook's other sheet positions
(active tab, print areas, scoped names) are computed with the chart sheets
counted. A chart sheet is left out on save when the chart is no longer
valid for the workbook: a sheet it plots was deleted or renamed, or a
worksheet took its name.
write_csv visited every position of the used range and appended to one growing
String with no limit, so two cells far apart (A1 and XFD1048576) asked for
about 16 GiB of commas. The output is now capped at 512 MiB: a lower bound
(delimiters and line ends of every row) is checked before anything is
allocated, and the text written so far is checked after each row. Over the
cap, write_csv returns IoError::TooLarge naming the rows, columns and limit,
and Save As / Export CSV and TSV report it without writing a file. Accepted
exports are unchanged. write_csv now returns a Result.
The Show group stacked Ruler, Formula Bar, Gridlines and Headings in
one column, but the ribbon body fits only three rows, so Headings was
cut off at the bottom and could not be reached. The four checkboxes now
sit in two columns of two (Ruler/Gridlines, Formula Bar/Headings), as in
Excel's Show group. Checked in English and German, which has the
longest labels.

Excel stores the path of a linked workbook relative to the file that uses it, and rewrites it when the file is saved into another folder. The path was kept as text, so after Save As it named a file next to the new copy: a missing link, or another workbook with the same name. Relative externalLinkPath targets are now resolved against the folder the workbook was read from and written relative to the folder it is saved into (absolute when there is no relative path, on another drive).
Cell format 0 always mapped to the model's built-in Calibri 11 default, so the file's Normal font was replaced on save and every default-formatted cell changed size. The Normal style now takes the font of cell format 0, and a Normal font in the theme's body face is written with scheme="minor" again.
Excel uses the cached cell values of a saved file only when workbook.xml has both <fileVersion> and the calcFeatures extension; without them it recalculates everything on open, and lookups into closed workbooks come back as #CALC!. Both are now read into the workbook's kept content and written back in schema order: fileVersion first, the calcFeatures ext in <extLst> last. A workbook that had neither gets neither.
A page that frames GridCraft on the same origin can now open workbooks
in it and store what it saves, through postMessage, instead of Save and
Export becoming browser downloads. Built for a Nextcloud integration,
but nothing in it is host-specific.
Only the web shell changes:
- gridcraft:open from the parent goes through the inbox, like a picked
or dropped file
- Services::download sends the bytes to the parent (gridcraft:save); an
.xlsx workbook handed over counts as saved under that name
- gridcraft:dirty reports unsaved changes; gridcraft:ready and
gridcraft:failed report start-up
- in host mode no sample opens, and ?author= names the user for notes
and comments
Enabled only by ?host=parent inside a frame; only the parent window on
the page's own origin is heard or answered. Without it nothing changes.

text_width sums in u64; an all-zero or non-finite dash array is written as
solid ([] 0 d); stroke widths are clamped to >= 0 (NaN -> 0); drawing calls
with non-finite or non-positive geometry return before storing anything.

Info strings were WinAnsi; PDF text strings are PDFDocEncoding or UTF-16BE.
Printable ASCII stays a literal string; anything else is a <FEFF...> hex
string. Info strings are capped at 1024 characters.

home.rowHeight, home.autofitRowHeight and data.ungroup change row hidden
state without marking the edit structural, so SUBTOTAL(101-111) kept a stale
value. Found by the command-sequence fuzz (seed 3).

With values on rows and no column field, the header cell above the data
column reads "Total", as Excel saves it (tabular checked against a real
file).
Σ Values in Columns always comes after the last column field: the column
layout doesn't place it anywhere else, so `pivot.moveField` no longer
stores a position there, the reader ignores where `-2` sits in colFields
and the writer puts it last.
`pivot.changeSource` removes dropped row and column fields one by one so
Σ Values keeps its place ahead of the field it preceded.

The Format Cells dialog drew English literals in every language. Its
tabs, labels, options and protection note now go through Language::tr,
as do dialog titles and the shared OK/Cancel buttons. The Fill tab is
keyed Format Cells|Fill because the Alignment tab's Fill is a different
word in some languages. d.tab keeps the English name.

Excel rejects a text criterion longer than 255 characters in COUNTIF(S),
SUMIF(S), AVERAGEIF(S), MAXIFS and MINIFS with #VALUE!; GridCraft matched
it anyway. Found by the calc oracle on an Excel-saved report where a
268-character concatenated criterion caches #VALUE!.

The exponent sign goes right before the exponent digits, after any literal that follows
the E; ? pads exponent digits with spaces; % and commas never scale a scientific section;
zero shows 0 in every integer placeholder. Checked against the 248 TEXT() rows of Apache
POI's NumberFormatApproxTests.xlsx, copied as data into a test.
home.deleteRows/deleteColumns used only the last selected area. They now
take every area (or a comma list like "3:3,7:8"), merge them and delete
from the last to the first inside one edit, so it is one undo step.
