Site infrastructure pass: language switcher, hreflang, sitemap and audit fixes

Coordinated infrastructure release covering navigation, internationalization signals, crawl health and security headers. Triggered by a full Screaming Frog audit and a user report of the language switcher returning to the homepage on internal pages.

  • Language switcher rewritten to keep users on the same page across languages (was redirecting to language homepage)
  • Cache-busted to v=82 across all pages so browsers fetch the updated bundle
  • HTML sitemap rebuilt with all 446 canonical pages organized into 15 sections (was 72 links covering only 16% of the site)
  • llms.txt and llms-full.txt linked in footer across 830 pages
  • 59 distinct broken internal links repaired (274 substitutions sitewide)
  • 9 missing hreflang stubs created so language alternates resolve cleanly
  • 280 over-length meta, og and twitter descriptions trimmed to within snippet limits
  • Content-Security-Policy header added to _headers and .htaccess
  • 6 explicit Content-Type rules added for special files (webmanifest, llms.txt, ai.txt, humans.txt, security.txt, llms-full.txt)
  • 3 bare-slug 301 redirects added for guides that were 404ing from external referrers

Spanish (LatAm) localization opens with first translated comparison pages

First wave of LatAm Spanish translation goes live across the comparison library. The localization includes full hreflang signaling, language-specific stub fallback for untranslated pages, and a path-correct asset pipeline that resolves regardless of page depth.

  • Two flagship comparison pages translated end-to-end including 142 preserved B² superscript references on the Bitcoin L2 page
  • Compare hub localized at /es/compare/ with the existing 95 prior translations now path-corrected
  • Asset path migration converted 287 ES pages from depth-relative to root-absolute URLs to eliminate CSS and JS 404s at deeper paths
  • Hreflang declared on every page covering en, es, pt-br, vi, tr, ko plus x-default

// Changelog FAQ

Common questions

Six questions covering update cadence, versioning, archival policy and the roadmap.

How often does Crawlux ship updates?

Methodology updates ship quarterly with minor revisions and annually with major reviews. Tool updates ship roughly bi-weekly. API and documentation updates ship as features land. Every change is logged here with a date and category. Subscribe via the changelog RSS feed (planned) or check this page periodically for updates.

What does each category mean?

Methodology updates affect how audits score (analyzer weighting, threshold changes, calibration source updates). Tool updates affect the audit dashboard and PDF generation. API updates affect the JSON output structure and webhook payloads. Documentation updates affect the resource guides, methodology page and developer docs. Fixes are bug fixes and minor corrections.

How is methodology versioning handled?

Methodology versions follow semantic versioning. v3.0 is the current major version. Minor revisions (v3.1, v3.2) adjust weights and thresholds. Major reviews (v3.0 to v4.0) reconsider the analyzer set. Audits store the methodology version they ran against, so historical comparisons remain reproducible across version updates.

Will old methodology versions stay accessible?

Yes. Every methodology version gets archived for audit reproducibility. Sites audited in earlier versions can be re-scored in the current version on request. Score changes between versions get flagged with the version delta so users understand what changed and why. The current version is always documented on the methodology page.

Can I subscribe to changelog updates?

Three options. First, follow this page periodically. Second, subscribe to the changelog RSS feed (planned for Q3 2026). Third, run a free audit and reply to any of the email follow-ups confirming changelog interest. Major changes are also announced via the press releases on the press page and via the email follow-up sequence.

Is there a roadmap for upcoming features?

The current roadmap covers three major items. First, the public REST API ships Q4 2026 (documented on the docs page). Second, methodology v4 with expanded on-chain signals planned for Q1 2027. Third, native integrations with major SEO platforms planned for Q2 2027. Roadmap subject to refinement based on customer feedback during beta.
