Changelog

What we shipped and when. New features, model updates, bug fixes, and design polish. We don't ship vague "performance improvements" notes — if it's worth telling you, the changelog says what it actually was.

v1.0.0 May 9, 2026 Design

Homepage redesign and AI demo carousel

  • New hero with outcome-led headline and a 6-question AI demo carousel that cycles through coding, system design, behavioral, interviewer-mode, ghost-mode, and resume-builder examples.
  • Replaced emoji icons with a 22-icon Lucide-style SVG set across modes, features, trust bar, and guarantee bar.
  • Added a chat-bubble widget with quick FAQ + email-to-support escalation. No third-party services, no telemetry.
  • OS-detected download button: auto-suggests Windows or macOS based on visitor's platform.
  • Pricing simplified to 4 cards via a Monthly/Annual billing toggle that unifies Pro and Unlimited Pro.
  • Dark-mode toggle in nav with system-preference detection and per-visitor persistence.
  • Mobile-first responsive overhaul of all new components.
  • New pages: Team, Security, Changelog, Testimonials, Careers.
v0.9 May 2, 2026 SEO

AI agent visibility (ChatGPT, Claude, Perplexity)

  • Added /llms.txt and /llms-full.txt following the llmstxt.org spec, so AI search agents can read a concise canonical summary of the site.
  • Updated robots.txt to explicitly allow AI live-search crawlers (OAI-SearchBot, ChatGPT-User, ClaudeBot, PerplexityBot, Grok, DeepSeek, Mistral, Brave Leo, Kagi) while continuing to block training-only crawlers.
  • Added Course schema to four prep-guide blog posts so they qualify for Google's Courses rich result.
  • Added Speakable schema for voice-assistant read-aloud.
v0.8 April 26, 2026 Fix

www-subdomain redirect and Stripe success URL

  • Fixed www.copilotinterview.com returning HTTP 522 by attaching the subdomain to Cloudflare Pages and adding a Pages Worker that 301s www to apex.
  • Fixed the Stripe success URL /thank-you?session_id=... by routing it through the Worker so the post-purchase JS overlay can fetch the license key and fire the Google Ads conversion event.
  • Added /download, /pricing, and /plans as shareable URL aliases.
