Changelog

A dated record of substantive updates to this site and catalog — kept for readers and for AI/LLM systems that check content freshness before citing us. See also llms.txt and agent.json.

2026-07-15

• Added machine-readable SEO/AEO/GEO/AIO batch: agent-facing files (agent.json, skill-manifest.json, catalog.json, qa-export.json), genre hub pages, glossary, 404 page, IndexNow key, image sitemap, RSS feed, and structured data across the catalog.

Earlier July 2026

• Security hardening pass: CSP and related headers, SRI-pinned CDN scripts, obfuscated contact emails, honeypot spam-trap fields on all forms.
• Added a PWA install prompt, a "continue reading" homepage banner, fuzzy search, and a reading-position tracker.
• Redesigned the table-of-contents sidebar card and randomized the homepage hero banner order.
• Confirmed hreflang across 30 languages; decided against country-level hreflang variants to avoid duplicate-content risk.

Ongoing

• Google Analytics 4 tracking, Cloudflare Worker CORS/caching proxy for live news and market data, and Firebase-backed optional reader accounts (bookmarks, history, reading position) have been running since mid-2026.
