Revision history for Data-HyperLogLog-Shared

0.03      2026-07-22
          - On-disk format change (v1 -> v2): an existing 0.02 file is
            refused; recreate it.
          - Fix a use-after-free in merge(): 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.
          - Resolve argument magic before capturing the path string.

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      2026-06-25
          - Initial release.
