What's New in DomainDig
5.5.3
October 29, 2026
This update brings everything since 5.0.3. FIXED • A domain typed with a space in it closed the app. • Availability could never report a name as free, which is also why alternative name suggestions never appeared. • Redirect tracing could not follow plain http — the http-to-https hop being the one the check exists to show. • SMTP integration credentials were sent unencrypted on the "Plain" security mode. They are now refused without TLS. • Turning on iCloud sync erased every tracked domain's tags. • Sync conflicts were decided by device clocks, so a skewed or long-offline device could win or lose arbitrarily. They now use iCloud's own record dates. CHANGED Pro+ promised five capabilities and four of them could not produce data in a shipping build. Pricing and reputation have been removed. Ownership history and DNS history are now free for everyone, since they are derived from your own snapshots. Extended subdomain discovery has moved to Pro. Pro+ is now shared portfolios, unlimited audit sessions and the full intelligence breakdown. NEW • A lookup can run a Quick profile instead of every check. • Third-party enrichment can be declined. With it off, DomainDig contacts rdap.org, crt.sh and ipapi.co for nothing — ownership, subdomain discovery and IP location become unavailable, and registration is decided from DNS alone. • A finished run can upload its report to your own S3-compatible bucket: S3, R2, B2, MinIO, Wasabi or Spaces. JSON always, PDF and CSV if you want them. Pro+. • A new icon, built from the domain name system itself — a tree read from the root down. It follows your accent if you pick Graphite, Forest or Plum. Pro+. • Pasting a list of domains tells you which entries it skipped, instead of dropping them silently. • The watchlist is reached from the Dashboard now, and Workflows from the Inspect tab. • History keeps 50 snapshots on Free, 250 on Pro and 2000 on Pro+. ACCESSIBILITY • Every picker shows its value in full at large text sizes instead of cutting it to an ellipsis. • The Privacy Policy link opens the policy rather than a missing page. • Recent searches have a full-size Clear button and read correctly in VoiceOver.
