Release Notes
1.10.3 — Performance. Export-DhDashboard is dramatically faster on large tables: ConvertTo-DhJsonString now short-circuits its nine regex passes with a single IndexOfAny pre-check, since real table data is overwhelmingly plain text that needs no escaping. Measured 1.27 ms -> 0.014 ms per call (90x); a 20,400-cell report exports in 5.2 s instead of 79.7 s (15x), and marginal cost falls from ~2.9 ms to ~0.08 ms per cell (~40x) — a 338,000-cell report drops from ~16 min to ~30 s. Escaping behaviour is unchanged and byte-identical: the nine passes are untouched, only skipped when provably unnecessary. Their ORDER is load-bearing (CR is dropped, not escaped, so '<' CR '/script>' collapses into '</script>' mid-pass and is caught by the '</' rule) — this is now documented and pinned by tests so a future single-regex rewrite cannot reintroduce a script breakout. 392 tests. See CHANGELOG.md for older releases.
1.10.1 — Bug-fix patch (from an internal code review). SECURITY: table cells with CellType='progressbar' now HTML-encode their label value — previously a non-numeric value was injected via innerHTML, an XSS sink that contradicted the "table cells are auto-encoded" guarantee. Also: the duplicate-Id guard now covers Add-DhBarChart / Add-DhCollapsible / Add-DhFilterCard / Add-DhHtmlBlock / Add-DhPieChart (the other 11 block cmdlets already had it); and the table header "select all" checkbox now selects every row of a -Pageable:$false table instead of only the first page. No API changes. 379 tests.
1.10.0 — Opt-in 12-column grid layout. Blocks and tables accept -GridSpan (1-12); as soon as one is set, the report body becomes a 12-column CSS grid and each element spans the requested columns (unspanned elements stay full-width). Put two half-width charts side by side with -GridSpan 6, three-across with -GridSpan 4, etc. Collapses to a single column below 900px. Fully non-breaking: a dashboard with no -GridSpan is byte-identical to 1.9.0 (sequential flow). 372 tests.
1.9.0 — Global filters. New Add-DhGlobalFilter cmdlet adds a page-level control (a facet dropdown, or a from/to date range) to a filter bar above the report body. Changing it re-filters EVERY table that has the named field at once, and charts derived from those tables re-aggregate; tables without the field are unaffected. Multiple global filters combine with AND, and selections persist in the URL hash. Non-breaking — dashboards with no global filter are byte-unchanged. 365 tests.
1.8.0 — Internal refactor, no functional change. The ~3,400-line dashboard runtime JavaScript (previously one here-string in Get-DhJsContent.ps1) is now authored across five cohesive fragment files — Get-DhJsCore / Get-DhJsBlocks / Get-DhJsNav / Get-DhJsTable / Get-DhJsBoot — concatenated by Get-DhJsContent. The assembled output is byte-for-byte identical to 1.7.0 (verified); generated dashboards are unchanged. Purely a maintainability improvement. 355 tests.
1.7.0 — UX & performance. (1) Interactive topology maps: Add-DhTopologyMap now renders in a fixed viewport with drag-to-pan, wheel-zoom, a zoom/reset toolbar, and a +/- toggle on every parent node to collapse its subtree. Default on; pass -Interactive:$false for the pre-1.7.0 static view. (2) Accessibility: honours prefers-reduced-motion, adds aria-sort + keyboard operation to sortable table headers, an aria-live result-count region, and a focus ring on sortable headers. (3) Large tables: -Pageable:$false now renders ALL rows (previously it wrongly showed only the first page) and virtualises the DOM above 150 rows so "show all" stays fast. Also fixes Add-DhTabs throwing on a single tab. Non-breaking. 355 tests.
