Changelog

Convention: a major entry is a new tax year, a new calculator, or a content overhaul. A feature entry is a new module or upgrade to an existing tool. An update entry is a refinement, correction, or non-breaking improvement.

New tools: tax code decoder, HMRC letter decoder, tax-year transition checker, Self Assessment readiness checklist, side-hustle tax wizard.
New pages: Independence statement, Open methodology, Changelog (this page).
Content: per-calculator methodology pages framework introduced; first five calculators get dedicated formula explainers.
Cross-linking: every technical term on calculators and guides now auto-links to the matching glossary entry on first occurrence.
UX: reading time / completion time badge added to every page with substantial content; branded print-summary on every calculator.
Distribution: RSS feed at /rss.xml; build pipeline auto-generates feed on every deploy.

Visible breadcrumbs derived from existing BreadcrumbList JSON-LD on 143 content pages — so users see the same hierarchy Google does.
Related calculators 3-card footer module on every calculator (41 pages), with category-aware and hand-tuned cross-links.
Sources & references panel on the 7 calculators that lacked topic-specific HMRC / FCA / MoneyHelper citations.
Trust block added below every calculator: visible "Last reviewed" date, editorial-team byline (E-E-A-T signal), and explicit disclaimer.
Two new policy pages: Terms of Use and Content Disclaimer.

Kids lesson packs print rewritten — popup-window approach replaces the brittle window.print() + @media print stage. Both lesson packs and worksheets/certificates now print correctly in any browser context.
Build pipeline hardened: search index, JSON-LD schemas, breadcrumbs, related-calc footers, sources, and trust blocks all rebuild on every Netlify deploy. Manual-step drift is no longer possible.
Dev/QA artifacts removed from the deployable tree (browser profile, screenshots, internal audit JSON, working-notes MD).

Schema upgrade: 43 calculator pages got SoftwareApplication JSON-LD; 10 FAQ pages got single-question FAQPage blocks; the FAQ hub got a 10-question multi-entry FAQPage.
Skip-to-content links rendered on 102 pages where the CSS already existed but no anchor was present.
Render-blocking JS fixed on 8 kids pages by adding defer to tdx-kids-progress.js.

Security headers tightened: full Content Security Policy, 2-year HSTS with preload, COOP, X-Frame-Options, FLoC opt-out.
Pretty URLs: 144 auto-generated /foo → /foo.html redirects covering every content page.
Sitemap regenerated from disk with real lastmod dates per page; previously drifted by ~10 entries.
Netlify scenario-sync function hardened with per-IP rate limiting (5 req/60s) and 256 KB body-size guard.
Organization JSON-LD on the homepage extended with logo, description, knowsAbout, areaServed.
About page title rewritten to capture "who runs it, how it's funded, editorial stance".

2026/27 tax year goes live. All calculators updated to the 2026/27 rates and thresholds: Income Tax bands, NI rates, dividend allowance (£500), CGT rates and AEA, ISA allowances, pension annual allowance, SDLT bands, Child Benefit HICBC threshold (£60,000), and the residential CGT 60-day reporting rule.
