Revision history for Data-NDArray-Shared

0.07  2026-10-16
    - Distinguish copied files from aliases during arithmetic.
    - Keep PDL aliases alive and reject incompatible or frozen backing files.
    - Load required PDL operations automatically and improve bulk fills.

0.06      2026-09-26
          - A reshape killed part-way is repaired to the 1-D view instead of
            leaving the file unopenable.
          - Segments are reserved, so a full filesystem fails the constructor;
            DATA_NDARRAY_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.
          - unlink() reports a failed removal; a missing file is no error.

0.03      2026-07-22
          - Fix a use-after-free in add(), subtract() and multiply() when a
            tied peer destroys the object; it now croaks.
          - On-disk format change (v1 -> v2): recreate 0.02 files.
          - 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      2026-06-26
          - Initial release.
