- Parse the top-level RDAP `redacted` array (RFC 9537) into a new `redactions` field on `DomainRecord`; set `privacyEnabled` when any redaction references "registrant"
- Expose `street`, `city`, `state`, `postalCode`, `country`, and `countryCode` on both `RegistrarInfo` and `Contact`; extract ISO 3166-1 alpha-2 from the vCard `cc` parameter (RFC 8605)
- Split `tel` entries by fax type parameter (`"fax"` / `["work","fax"]`) into separate `tel` and `fax` lists; collect multiple email addresses as an array, collapsing singletons to a plain string
- Prefer an exact `registration` event match over `reregistration` when extracting `creationDate` (RFC 9083)
- Merge `redacted` arrays in `mergeRdapDocs`, deduplicating by JSON identity
- Split `adr` street on `\r?\n` only (not commas) to avoid splitting inline comma-separated addresses
- Parse `Retry-After` on RDAP `503` responses (previously only `429`), exposing `retryAfterMs` on the attempt and on the top-level result when `rdapOnly` makes it terminal
- Fix the WHOIS `BLOCK_PATTERNS` regex to use `[\s\S]` instead of `.` so a block notice that spans multiple lines (e.g. `"Your IP address\nhas been blocked"`) is still classified as `blocked`
- Update README to document `retryAfterMs` on `LookupResult`, clarify `rate_limited` / `blocked` / `unparseable` semantics, and note referral-host validation behaviour
- A server that accepts the connection and closes it without sending data now rejects with `errorCode: "no_data"` and `stage: "read"` instead of resolving with an empty string
- OS-level `ETIMEDOUT` errors are mapped to the same `timeout` / `stage` shape as the library's own timer, with `stage` derived from whether the socket had connected yet
- `ECONNRESET` after data arrives is no longer marked `partial: true`; it was a complete reply and the reset just signalled the end of the stream
- `stage` on `LookupAttempt` is now documented as covering all WHOIS failures (not only timeout failures)
- Resolve `LookupResult` with an `attempts` array describing every network operation (phase, server, duration, error) so failures recovered by fallback remain visible
- Add `deadlineMs` option for a hard cap on total lookup time, distinct from per-operation `timeoutMs` (lowered default from 15 s to 10 s)
- Add `errorCode` (machine-readable `LookupErrorCode`), `errorPhase`, and `errorServer` to `LookupResult`; `timeout` covers both per-op and deadline timeouts, `aborted` means the caller's signal fired
- WHOIS timeouts now distinguish `connect` vs `read` stage and resolve with partial text (marked `partial: true`) when data arrived before the socket stalled
- Drop Node 18 support; minimum engine is now 20
Updated the DomainRecord interface to include detailed comments for clarity and added a new privacyEnabled field to indicate if the registrant's information is privacy-redacted. Enhanced normalization functions for both RDAP and WHOIS to derive the privacy flag based on registrant keywords. Updated tests to verify the correct functionality of privacy detection in both normalization processes. Additionally, the README was updated to reflect the inclusion of the privacy flag in the normalized output.
Added support for following registrar WHOIS referrals with configurable hop limits. Introduced new options in LookupOptions for maximum referral hops and RDAP link handling. Updated README to reflect these changes and improved the lookupDomain function to utilize the new referral logic. Added utility functions for merging RDAP documents and extracting related links.
