Revision history for Data-RadixTree-Shared

0.06      2026-09-26
          - A writer killed mid insert, delete or clear no longer publishes a
            stale value or links reused nodes.
          - DATA_RADIXTREE_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      2026-07-23
          - On-disk format change (v1 -> v2): recreate 0.02 files.
          - clear() no longer hands a node out twice and loses keys.
          - Edge splits are crash-safe and recycle nodes; an exhausted pool
            fails the insert instead of dropping the key.

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).

0.01      2026-06-26
          - Initial release.
