Revision history for Data-Histogram-Shared

0.06      2026-09-26
          - A writer killed mid record, merge or reset no longer leaves a
            total the buckets cannot reach.
          - DATA_HISTOGRAM_SHARED_SPARSE=0 reserves segments up front, so a
            full filesystem fails the constructor, not a later write.
          - A failed create no longer leaves a full-size file behind.

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
          - Fix a use-after-free in merge() and record_many() when tied or
            overloaded arguments destroy the histogram; it now croaks.
          - On-disk format change (v1 -> v2): recreate 0.02 files.
          - Fetch get-magic on optional arguments before testing them.

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).
          - record() now croaks on a value above highest_trackable_value
            (previously such a value was silently bucketed to the top).

0.01      2026-06-25
          - Initial release.
