Changelog

What we shipped.

A running log of improvements, fixes, and new features. We ship frequently, document everything, and believe you should know exactly what's changed.

v1.4NewFebruary 10, 2026

LLM Readiness scoring and llms.txt validation

Cassian now scores your store's readiness for AI search engines. We check for llms.txt presence and validity, structured data completeness for AI consumption, FAQ schema coverage, and content extractability. This is the fifth layer of the Cassian Score™, weighted at 10% of your overall score.

v1.3ImprovedJanuary 28, 2026

Weekly digest email redesign and Slack notification beta

The weekly digest has been completely redesigned. Clearer score breakdowns, prioritised findings with direct links, and a new "What changed this week" section. Plus, Slack notifications are now in beta — get scan results and weekly summaries directly in your Slack workspace.

v1.2.1FixedJanuary 14, 2026

Fixed scan timeout on stores with 1,000+ products

Stores with large product catalogues (1,000+ products) were occasionally experiencing scan timeouts during the platform consistency layer. We've optimised the GraphQL query batching and increased the timeout threshold. Scans for large stores now complete reliably within 90 seconds.

v1.2NewDecember 20, 2025

Multi-site dashboard and additional site billing

You can now manage multiple Shopify stores from a single Cassian dashboard. Each additional site is $15/month regardless of your tier. Switch between stores instantly, compare scores side by side, and get a unified weekly digest covering all your properties.

v1.1.1ImprovedDecember 8, 2025

Improved translation quality detection accuracy

We've refined the Cassian AI™ translation analysis engine to reduce false positives by 35%. The system now better distinguishes between intentional localisation choices and genuine translation errors, particularly for idiomatic expressions and brand-specific terminology.

v1.1NewNovember 25, 2025

Cassian Sentinel™ uptime monitoring for Protector and above

Protector, Guardian, and Prime tier customers get Cassian Sentinel™ uptime monitoring with HTTP health checks every 5 minutes, SSL certificate expiry tracking, domain registration monitoring via RDAP, and confirm-before-alert to eliminate false alarms. Prime tier gets 1-minute intervals.

v1.0.2FixedNovember 12, 2025

Fixed false positives in broken link detection

Our link checker was flagging some URLs as broken when they were actually behind rate limiters or Cloudflare challenges. We've added retry logic with exponential backoff and improved our handling of 403/429 responses. False positive rate for broken links is now below 0.5%.

v1.0.1ImprovedOctober 28, 2025

Performance improvements — scan time reduced by 40%

Major optimisation to the scan pipeline. We now parallelise page rendering and API calls more aggressively, reducing the average full scan from 35 seconds to 21 seconds. For stores with fewer than 100 products, most scans complete in under 15 seconds.

v1.0NewOctober 15, 2025

Cassian launches — the Shopify store health platform

The initial public launch of Cassian™. Five scoring layers (technical health, content quality, translation accuracy, platform consistency, LLM readiness), the Cassian Score™, weekly digest emails, five pricing tiers from free to $999/month, and a dashboard that shows you exactly what needs attention. This is day one.
