Revision history for Data-CuckooFilter-Shared

0.02      2026-07-09
          - Security and robustness hardening; backing files now created mode
            0600 (pass a file-mode argument to new() for cross-user sharing).
          - New count_of($item) method: occurrence count 0..8 (times added minus
            removed), saturating at 2*slots_per_bucket. Lets the filter double as
            a small counting set without a counting Bloom filter's overhead.
