Revision history for Data-CuckooFilter-Shared

0.03      2026-07-23
          - On-disk format change (v1 -> v2): an existing 0.02 file is
            refused; recreate it.
          - Resolve argument magic before capturing the path string.
          - Re-read the class name at the point of use in the constructors, so
            a later argument's magic cannot dangle the INPUT-captured PV.
          - Document that a crash mid-eviction can drop a fingerprint.

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.

0.01      2026-06-25
