0.6.0

Screen-reader pairings tested: none yet — the VoiceOver pass is prepared and not yet run
(issue #5). Browsers: Chromium, the whole
e2e suite. WebKit (Playwright's, not Safari): the whole suite; its one failure, the plain-DOM
stand-in counting a second table, is fixed in this release (#93). Firefox: not run:
Playwright's Firefox does not start on the release machine.

What breaks (details in the entries below):

• the pivot's header part moved from its <thead> to each column header cell (#29);
• in the Rust crates, the opengrid types no longer implement serde — read and write them
  with opengrid_json (#41). The npm package's JavaScript API is unchanged apart from
  additions.

Module sizes (brotli, just measure-modules): the elements 215.8 → 204.1 KiB, the engine
124.9 → 115.2 KiB — serde left both modules (#41), and the engine now answers pivots (#28).

Added

• Data without JavaScript (#84). A page
  can write its data as a plain <table> inside an element. Without script, that's what
  readers and crawlers see; once the element has rendered, its shadow root replaces it, so
  nothing is read twice. When the module can't load, the plain-DOM stand-in now shows the
  page's table (through a <slot>) instead of hiding it behind an empty skeleton. The
  skeleton only shows when there is no table of its own.
• The pivot in the browser (#28).
  createLocalProvider and createWorkerProvider answer <opengrid-pivot>: the engine runs
  the pivot's grouping sets over the data the page loaded, with the server's limits
  (Engine.pivot, Engine.pivot_columns, a pivot message in the worker). The element calls
  a provider's new optional pivot(json) and falls back to execute, so providers of a page's
  own keep working; createPivotProvider has pivot too. examples/pivot-demo/browser.html
  shows it without a server.
• XLSX export on the server (#72).
  POST /export/{source}?format=xlsx writes an Excel workbook, and exportRows(rest, query, { format: "xlsx" }) asks for it through createRestProvider — with any other provider it is
  a TypeError. Values are Excel types where Excel holds them exactly (numbers, dates,
  date-times in UTC, booleans) and text where it cannot (integers past 2⁵³, decimals past 15
  digits, sub-millisecond timestamps), so no value changes; Excel's row and cell limits are
  errors, never a shortened file. New server-side dependency: rust_xlsxwriter, behind the
  feature xlsx of opengrid-export, so the browser modules do not carry it.
• <opengrid-table> and <opengrid-pivot> can be styled, and the table takes formats
  (#29). Both render into a shadow root, so
  no page rule reached their cells. They now carry parts named like the grid's — table,
  caption, header, row, cell, the table's sort-button, the pivot's row-header and
  total-row — and examples/pivot-demo and examples/table-demo style them through
  ::part. The table shows its values as the grid does: formats apply to its cells, and
  presentation (set_columns) gives a column its title, align, mono, emphasis and
  muted; the grid's width, aggregate and facet are refused for a table with an alert
  rather than ignored. A number is right-aligned by its type, as in the grid.
  What breaks: the pivot's header part was on its <thead>; it is now on each column
  header cell, like the grid's.

Changed

• One JSON codec for browser and server, and no serde in the browser
  (#41). opengrid-json reads and writes
  every JSON form — query, schema, view, texts, errors, the JSON result — on both sides,
  so the two cannot read the same bytes two ways. serde and serde_json are gone from
  both browser modules. Against 0.5.0, with everything else in this release (just measure-modules, brotli): the elements 215.8 → 204.1 KiB, the engine 124.9 → 115.2 KiB,
  although the engine now answers pivots too. What is read and refused is what serde_json read
  and refused (checked against it as an oracle); what is written is what it wrote, keys
  aside — an object now keeps the order it is written in instead of sorting its keys —
  and one rare case: where a float has two shortest spellings, the one closer to the
  value is written. Both read back to the same number.

  What breaks (Rust crates only; the npm package and its JavaScript API are
  unchanged): the opengrid types no longer implement serde::Serialize/Deserialize.
  Read and write them with opengrid_json (from_str, to_string, FromJson, ToJson);
  Value::deserialize_typed is Value::from_json_typed, and a filter literal is an
  opengrid_json::Json.

Fixed

• <opengrid-table> says it is loading (#86).
  Until its first answer it was a table with a caption and no rows, which a screen reader
  couldn't tell from an empty one. The waiting table now carries aria-busy="true", and
  the table with its answer doesn't.
