Overview

Current version and semver

Site version 0.0.5 · last updated 21 May 2026.

Version numbers follow semantic versioning for the site as a whole, not individual guides. A patch bump may fix typos or add pages; a minor bump adds sections or notable content; a major bump signals breaking changes to URLs, structure, or policy.

Releases below are newest first. Each section documents what shipped in that version — for machine-readable discovery, see llms.txt and the AI statement.

v0.0.5 · 21 May 2026

Guide consolidation

Merged overlapping architecture, accessibility, and performance guides so each topic earns its URL — fewer duplicate essays, clearer indexes, and updated cross-links across the site.

  • Architecture: platform-first content unified under progressive enhancement strategy; CSS naming and documentation folded into css-architecture and frontend-governance; component ownership into design-system-governance; CSS performance under css-performance-architecture
  • Accessibility: dynamic announcements and live regions merged; testing guides unified as accessibility testing strategy; landmarks in semantic HTML; focus traps in focus management; accessibility-is-product-quality lives on principles only
  • Performance: rendering strategy on static vs SSR vs CSR; lazy loading images in lazy loading strategy; third-party governance in third-party scripts; monitoring in frontend observability; hydration, islands, and progressive hydration in hydration and client interactivity; weight essay folded into JavaScript cost
  • Removed legacy redirect stubs — merged slugs no longer published (147 URLs in sitemap)
  • Updated standards link lists, llms.txt flagship guides, and guide FAQs for consolidated slugs
