NewTon DC Tournament Manager v4.2.10 — March 18, 2026
Download v4.2.10NewTon DC Tournament Manager Version 4.2.10 adds five standalone documentation pages served directly from the application, a comprehensive user guide, sitemap improvements for search engine visibility, and a small UX fix to the Setup Actions panel.
This release contains one change to tournament functionality (Double Elimination moved to top of Setup Actions) and is otherwise a drop-in replacement for v4.2.9.
A full user guide is now available at userguide.html. It covers the entire tournament workflow in seven sections:
Four standalone HTML pages are now served directly from the application, styled consistently with the landing page:
New page linked from the landing page's Get Started section. Covers the design philosophy and internals behind NewTon's crash-proof design: Single Source of Truth (MATCH_PROGRESSION lookup tables), Transaction History & Undo (event sourcing, surgical undo, auto-recovery), Data Separation (tournament data, transaction history, and global config kept strictly isolated), Offline-First Persistence, Strengths, and Known Limitations. Cross-linked to the Developer Console section in userguide.html, Privacy page, and REST API page.
Replaces the link to the GitHub markdown file in the landing page's "Get Started" section. Covers the full self-hosting workflow: Quick Start (3 steps), a complete annotated docker-compose.yml, persistent storage, environment variables, reverse proxy setup (including an Nginx Proxy Manager example), security headers, logo/QR customisation, and troubleshooting.
Replaces the GitHub link in the landing page footer. Covers the full privacy architecture: localStorage model, technical storage details, what NewTon doesn't do (no analytics, no telemetry, no external dependencies, no cookies, no accounts), storage key structure, export privacy, demo site model, self-hosting with the REST API, offline operation, FAQ, and summary.
New page linked from both docker-quickstart.html and privacy.html. Covers the complete REST API reference: overview, server requirements, directory structure, all three endpoints (List/Upload/Delete) with request/response examples and error tables, CORS headers, client-side feature detection, data format, security practices, and troubleshooting.
css/landing.css)New CSS classes shared across all documentation pages:
.docs-back-link — Fixed top-left navigation link in Insignia font.docs-content — Centered 760px column with doc-appropriate spacing.docs-toc — Warm cream table of contents box.terminal-wrap / .terminal-bar — macOS-style terminal blocks with traffic light dots (red/amber/green), dark background, soft green monospace text.docs-footer — Footer width constrained to match the 760px column.docs-quickstart — Styled numbered step list with CSS counter circles (used in userguide.html)Two cards have been added to the Get Started section. The User Guide card spans the full width of the section (below Local Use and Self-Hosted), with description text on the left and the "Read the Guide" button on the right. Below it, an Architecture & Reliability card links to architecture.html. Both cards use .get-started-card--wide. Applied to both landing.html and landing-page.php.
sitemap.xml updated with all doc pages indexed and priorities rebalanced by search value:
| URL | Priority |
|---|---|
/ | 1.0 |
/userguide.html | 0.8 |
/docker-quickstart.html | 0.8 |
/architecture.html | 0.7 |
/rest-api.html | 0.7 |
/privacy.html | 0.7 |
/chalker | 0.6 |
/?launch | 0.4 |
The noindex meta tag has been removed from all doc pages — they contain substantive content worth indexing.
Double Elimination Cup now appears above Single Elimination Cup in the Setup Actions panel. DE is the primary tournament format for most club use; the previous order (SE first) led to accidental SE bracket generation.
The <meta name="msvalidate.01"> verification tag has been added to both landing.html and landing-page.php to enable Bing Webmaster Tools indexing and analytics.
<meta name="description"> tags have been added to all five pages that were missing them — userguide.html, docker-quickstart.html, privacy.html, rest-api.html, and chalker/index.html. Each description summarises the page content for search engine result snippets.
