Revision history for Data-HyperLogLog-Shared

0.06      2026-09-26
          - A create that fails at mmap no longer leaves a full-size file
            behind.
          - Checking a file left by an interrupted create no longer allocates
            its pages on tmpfs.
          - Error messages no longer lose their reason to a long path.

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
          - On-disk format change (v1 -> v2): recreate 0.02 files.
          - Fix a use-after-free in merge() when a tied peer destroys the
            object; it 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).

          - Initial release.
