-1.9.0  2025-12-04
-       * PR #246: Make ldns_calc_keytag() available for CDNSKEY RR
-         Thanks tgreenx and pnax
-       * PR #247: Make ldns_key_rr2ds() available for CDNSKEY RR
-         Thanks tgreenx
-       * PR #248: Make ldns_rr_compare_{ds,ds_dnskey}() available for
-         CDS and CDNSKEY RRs. Thanks tgreenx
-       * PR #245: Make drill trace use IPv6 when used with -6
-         Thanks Paul Radford 
-       * Fix #254: Unquoted "value" rdata for CAA records fail to validate.
-         Follows the long string unquoted syntax from RFC8659, section 4.1.1.
-       * Fix #266: ldns-read-zone -u fails if a type is the only type in a
-         window and the type modulo 256 is equal to zero.
-       * Fix #271: Intermittent build failure with multi-job
-         builds (make -j).
-       * Add ldns-verify-zone -s option. It checks all signature results,
-         instead of passing by when one RRSIG validates. That prints output
-         for spurious RRSIGs, the failures for them.
-       * Fix RR types NSAP-PTR, GPOS and RESINFO to print unquoted strings.
-       * Fix memory leak when trying to read zones that have equal RRs.
-         the ldns_dnssec_*_add_rr() functions now return LDNS_STATUS_EQUAL_RR
-         when an already existing RR is tried to be added. This is a API
-         change, hence this also bumps the version to 1.9.0
-       * PR #282: ensure returning pkt with LDNS_STATUS_OK. Thanks grobian.
-       * PR #286: Fix RR Type AMTRELAY type nogateway, to print relay '.',
-         and memory leaks in parsing it.
-       * DSYNC is no longer a draft RR type and compiled by default
-       * RFC 9824 support: Compact Denial of Existence in DNSSEC
-       * The HHIT and BRID draft RR types
-       * PR #249: If RNG is already seeded, return early.
-         Thanks crrodriguez
-       * PR #221: Improve error messages. Thanks jschauma
-       * PR #256: Use SWIG_AppendOutput to support swig 4.3
-         Thanks pemensik
-       * PR #188: Homogenize paths for source files during compilation
-         Thanks duthils
-       * Fix #283: ldns-walk fails after update from 1.8.3 to 1.8.4
-         Thanks jschauma
-       * PR #200: Allow compiled tests to link to ldns statically via
-         environment variable. Thanks FGasper and pemensik
-       * PR #220: Optionally exclude ZONEMD RRs in ldns-compare-zone
-         Thanks gjherbiet
-       * Fix #285: A WALLET RR breaks TXT signing. Thanks bortzmeyer
-       * Fix #287: ldns-verify-zone hangs with missing NSEC3 RRs.
-         Thanks Roy Arends
-
 1.8.4  2024-07-19
        * Fix building documentation in build directory.
          Thanks Michael Tokarev

-DEVELOPMENT VISION
-
-Note: ldns has been in maintenance mode since 2020, with no plans for major
-features. We welcome PRs from contributors who want to add new functionality. 
-We also actively fix bugs, so users can continue to rely on ldns if its 
-current features meet their needs.
-
-We will continue to make occasional use of ldns in an experimental
-setting, such as during an IETF Hackathon to build a proof of concept for an
-Internet Draft.
-
-The natural successor to the ldns library is the domain library for Rust:
-https://github.com/NLnetLabs/domain
-
-We offer drop-in replacements for commonly used ldns example tools in dnst:
-https://github.com/NLnetLabs/dnst
