What changed, when, and why it matters.

August 23, 2026 — RFC 9535 JSONPath queries

• Added standards-based JSONPath queries for child selectors, wildcards, array slices, descendants, and filters.
• Added original-document and working-record targets, normalized match paths, bounded previews, JSON-array copy, and an undoable Use matches as dataset action.
• Kept query evaluation inside the browser worker with 1,000-character, 10,000-match, and 5 MB output limits.

August 23, 2026 — Name formatting

• Added a Name option to the Format tab with the same preview-first, undoable workflow as other column formats.
• Added surrounding-whitespace trimming and name-aware title case for apostrophes, hyphenated names, Unicode letters, and Mc prefixes.
• Added conservative missing-apostrophe restoration so compact forms such as osullivan, ohenry, and oconnor become O'Sullivan, O'Henry, and O'Connor without changing names such as Oscar, Oliver, or Owen.

August 23, 2026 — Compare and Join

• Added a dedicated two-source workspace for CSV, TSV, JSON, and JSONL files up to 10 MB each.
• Added one- or two-column key mapping, optional case-sensitive matching, and explicit added, removed, changed, unchanged, missing-key, and duplicate-key results.
• Added left, inner, and full joins with controlled collision suffixes plus spreadsheet-safe CSV and JSON exports.
• Kept parsing, comparison, conflict detection, join preparation, and export inside a dedicated browser worker with bounded previews.
• Added desktop, mobile, accessibility, security, and deterministic comparison regression coverage.

August 22, 2026 — Natural Voice

• Added Natural Voice as an additional writing tool without replacing the local data workbench.
• Added four editing tones, optional writing-sample guidance, an editable result, change summaries, and verbatim checks for structured details.
• Added a deterministic cadence audit and an independent line-edit pass for substantial or visibly formulaic drafts; a revision is accepted only when protected details remain and the audit does not regress.
• Added a same-origin Workers AI endpoint with streamed body limits, strict request validation, per-inference rate limiting, fail-closed limiter handling, randomized detail locks, and a route-specific Content Security Policy with Trusted Types.
• Hardened local JSON and JSON Schema complexity limits, prototype-like field handling, and spreadsheet formula escaping for invisible Unicode prefixes.
• Documented the AI processing boundary and the lack of detector, score, or watermark-removal guarantees.

August 22, 2026 — Search, answers, and trust

• Added route-specific entity, breadcrumb, application, article, and FAQ structured data.
• Added answer-first page summaries, accurate sitemap modification dates, AI crawler rules, an AI-readable site guide, and IndexNow release notifications.
• Published About, Privacy Policy and GDPR information, Security, Methodology, and Changelog references.
• Added canonical privacy-policy and GDPR aliases plus private privacy and security email routes.

August 22, 2026 — Expanded local workbench

• Added preview-first date, phone-number, number, text, email, and boolean formatting with invalid-value policies and undo.
• Added CSV filtering, stable sorting, column selection, renaming, missing-value filling, and multi-column deduplication.
• Added JSON repair, duplicate-key diagnostics, RFC 6901 path browsing, Draft 2020-12 schema validation, and TSV export.
• Versioned browser assets so each page and parser worker belong to the same release.

August 22, 2026 — Privacy and interface refresh

• Rebuilt the landing page around the functional data workspace.
• Clarified the server-to-browser processing boundary and improved its dark-mode contrast.
• Added mobile layout regression coverage.

August 21, 2026 — Initial public tools

• Added exact-row duplicate removal and the initial structured-data sampling work.
• Hardened response headers and prevented injected browser analytics from changing the no-network boundary.
