Revision history for Data-NDArray-Shared

0.04      2026-08-12
          - Recover a file left behind by an interrupted create instead of
            leaving the path unopenable.
          - Frozen read-only mode: freeze() seals a file-backed structure;
            new_readonly() maps it O_RDONLY and queries it lock-free.
          - 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 add(), subtract() and multiply():
            sv_isobject on the peer argument runs get-magic, so a tied
            argument can destroy this object before its handle is used
            again. Such a call now croaks.
          - 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      2026-06-26
          - Initial release.
