Data-HashMap-Shared-0.18

Changes for version 0.18 - 2026-09-01

  • Fix three crash windows that could corrupt a map when a writer was killed mid-operation: a removed entry's key, the entry count that resize() trusts, and a string's offset/length pair.
  • A cursor whose map was explicitly destroyed now croaks instead of reading freed memory.
  • List-returning keywords no longer force list context, so one used in scalar context stops adding values to the enclosing call.
  • reserve() rejects an out-of-range target instead of truncating it or reporting success.
  • Correct the crash-safety, iteration and upgrade notes; report NA instead of failing to build on a big-endian architecture.
