Revision history for Data::Deque::Shared

0.05  2026-06-01
    - Str pop paths: free temp buffer via SAVEFREEPV (leak on OOM-croak)

0.04  2026-05-26
    - drain: bounded recovery (~2s) for slots stuck after a crashed pusher
      (covers both WRITING and pre-claim_write EMPTY@gen windows)
    - slot publish is now CAS-only — prevents a stalled pusher from
      clobbering a slot drain force-recovered to EMPTY
    - new stats->{recoveries} counter for drain-time force-skips
    - header validation rejects files with elem_size invalid for the
      variant (Int = 8, Str ≥ 5)
