What's Changed

SemVer Minor

SemVer Patch

  • Make query cancellation per-query to avoid deadlock and cross-query cancellation by @iko1 in #86

ares_status_t migration

c-ares 1.20+ moved the status constants from int #defines into a real ares_status_t enum (a distinct Swift type). Bridged via an ares_status_t(_ status: Int32) initializer so the readable case ARES_SUCCESS: labels stay intact; behavior unchanged.
