Revision history for Data-SpatialHash-Shared

0.06      2026-09-26
          - A writer killed mid insert or remove is repaired from the live
            entries.
          - Segments are reserved, so a full filesystem fails the constructor;
            DATA_SPATIALHASH_SHARED_SPARSE=1 skips the reservation.
          - A failed create no longer leaves a full-size file behind.

0.05      2026-09-15
          - Recover a lock left ownerless by a corrupt file instead of hanging.
          - Fix a writer stall on ARM64 after readers release.

0.04      2026-08-12
          - A file left by an interrupted create is recovered, not refused.
          - freeze()/new_readonly(): sealed read-only mode, lock-free.
          - Hardening against tied and overloaded arguments.
          - unlink() reports a failed removal; a missing file is no error.

0.03      2026-07-17
          - On-disk format change (v1 -> v2): an existing 0.02 file is
            refused; recreate it.
          - Security and robustness hardening.

0.02      2026-07-03
          - Security and robustness hardening; backing files now created mode
            0600 (pass a file-mode argument to new() for cross-user sharing).

0.01      2026-06-22
          - Initial release.
