Revision history for Data-DisjointSet-Shared

0.07  2026-10-16
    - Fix shared-lock wakeups and interrupted reset publication.
    - Preserve permissions when another process finishes initialization.
    - Link threading dependencies explicitly.

0.06      2026-09-26
          - Recovery re-derives set sizes and num_sets after a writer killed
            mid-union, and reruns an interrupted reset.
          - Segments are reserved, so a full filesystem fails the constructor;
            DATA_DISJOINTSET_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
          - Recover a file left behind by an interrupted create instead of
            leaving the path unopenable.
          - Documentation and test-harness corrections.
          - unlink() reports a removal that failed; one already gone is not an
            error.

0.03      2026-07-22
          - Fix a use-after-free in union_many() when tied or overloaded
            arguments destroy the set; it now croaks.
          - On-disk format change (v1 -> v2): recreate 0.02 files.
          - Validate the element count from one snapshot at attach.

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      2026-06-26
          - Initial release.
