Changes in version 0.2.1 (2026-10-06)                  

  - Reject shared file IDs containing path separators or colons before
    cache files are inspected, replaced or downloaded.
  - Corrected DuckDB reader cleanup in examples and tests: partial SQL
    queries must not close a reader while Arrow may still be reading
    ahead.
  - Remove private synthetic logs when log writing or native stream
    creation fails, without removing cached data files or replacing the
    original error. Successful logs retain their session lifetime for
    lazy readers.
  - Indexed staged file paths so rewriting large manifests no longer
    repeatedly scans the full list of downloaded assets.
  - Retain verified completed downloads when another asset fails, so
    retrying a read reuses those files. Failed responses and incomplete
    files are discarded.
  - Reject invalid batch sizes and invalid or duplicate projection names
    before read requests. Zero-row snapshots resolve their schema
    without downloading data files, even when the server returns files
    despite the zero limit hint.
  - Declared minimum versions for the cli, httr2, purrr, rlang, and
    testthat APIs already used by the package and its tests.
  - Fixed partition-only and metadata-only CDF projections for inferred
    insert and delete changes, including tables whose first columns are
    partitions.
  - Eager Arrow materialization now closes its imported reader on
    success or error instead of waiting for garbage collection. Returned
    table buffers remain valid after reader cleanup.
  - BIGINT columns automatically use bit64::integer64 in to_tibble() and
    to_data_frame(), including empty and nested results. Arrow is a
    required dependency. Valid -9223372036854775808 values raise a clear
    error instead of becoming missing; Arrow materializers retain that
    value.

                        Changes in version 0.2.0                        

This release is a clean redesign of delta.sharing; it does not provide
compatibility aliases or migration shims for earlier package versions.

  - Added an R6 client, table, snapshot, and change data feed interface
    for discovery, metadata inspection, and reads.
  - Added Delta Kernel-backed snapshot and change data feed reads with
    projection, limits, predicate hints, version bounds, and timestamp
    bounds.
  - Added direct Arrow stream, Arrow reader, Arrow table, tibble, and
    data-frame materializers, including DuckDB interoperability.
  - Added support for bearer, basic, OAuth client-credentials, and
    private-key JWT profiles.
  - Added deletion-vector, column-mapping, partitioned, nested, and
    logical-type read support through Delta Kernel.
  - Added bounded parallel staging with interactive download progress
    and a table-scoped cache under R's session temporary directory.
