Changes in version 0.2.1.9000                      

                 Changes in version 0.2.1 (2026-06-09)                  

  - New prune_shared() removes shared memory regions orphaned by a
    process that was killed before it could clean up (#25).
  - When share() fails to create a shared memory region it now reports
    the requested size and, where applicable, an actionable hint (e.g.
    raising a container's /dev/shm limit) instead of a generic message
    (#29).

                 Changes in version 0.2.0 (2026-05-09)                  

  - Wire-format change (breaking): The serialization format and the
    shared memory region naming scheme have both changed.
  - shared_name() and map_shared() now round-trip for sub-lists and
    extracted elements, not just whole shared objects. Sub-object
    identifiers carry a bracketed index path (e.g. /mori_abc_1[2,3]).
  - shared_name() now returns NULL for non-shared inputs (previously the
    empty string ""); shared_name(x) %||% "" retains the previous
    behaviour.
  - share() on Linux fails with a clean R error when /dev/shm is too
    small (typical in containers, where the limit can be raised at
    start) instead of SIGBUS-ing mid-serialize (#14).
  - map_shared() on Linux no longer prefaults the whole region,
    restoring lazy first-touch access to match macOS.

                 Changes in version 0.1.0 (2026-04-21)                  

  - Initial CRAN release.
