Extension

Changelog

v2.0.0

Latest May 2026
New Features
  • Redesigned from the Ground Up: New interface rebuilt from scratch and aligned with the site, so the extension and the web app now share one consistent look and feel.
  • Drop Badge on Lifecycle Domains: When a domain is in grace, redemption, or pending-delete phase, the popup now shows a "Drops in ~X days" badge so you know when to backorder before the public release.
  • Marketplace Listing Badge: If a domain is listed on Afternic, Sedo, Spaceship, Atom, Dynadot, or another aftermarket platform, the popup surfaces the marketplace and asking price next to the domain name.
Improvements
  • Instant Search Results: The first response now comes from a cached availability check (50 to 200 ms) and refreshes with live registrar data when it lands.
  • Faster Detail Panel: Marketplace enrichment data (price, listing, history) now loads when you click into a result.
  • Wider TLD Coverage: .me, .edu, .jp, .ru, .it, .ie, .dk, and .se now route through their official RDAP servers and return full registration data instead of blanks.
  • RDAP TLD List Synced with Backend: Extension and api-manager now share one source of truth for RDAP server URLs, so newly-supported registries reach both at the same time without manual sync.
  • Iceland and Kenya Expiry Dates: Registries that report the expiration date under non-standard field names (ISNIC, KeNIC) now parse correctly and show the expiry where it should.
Bug Fixes
  • Error-page popup no longer claims a domain is "available" just because the current page failed to load. It runs a real WHOIS lookup first.
  • "View full details" button now opens the correct WHOIS detail page on the site instead of a 404.
  • Marketplace badge fetch hardened against transient enrichment errors so the popup never shows a stale or wrong listing.
  • Favorites list rendering hardened against unusual domain names.
  • Removed legacy code paths that were unused by the new UI.
