Ropendal 0.0.1.9000

• Development version after 0.0.1.
• Documentation: expanded README examples for batched I/O, async Aio handles, serializers/codecs, Arrow IPC streams via nanoarrow, lower-level iterators, S3-compatible MinIO benchmarking, and native C API scheduling.
• Documentation: aligned design notes, roxygen docs, and vignettes with the current async, credential, serializer, and native C API behavior.
• Documentation: documented R-universe Linux binary repository setup.
• Build: added a webR/wasm package-load fallback and local rwasm build helper.
• Reads: fs_read() / fs_read_bytes() now support multiple ranges from one path and list-of-ranges shapes across multiple paths, while preserving ordered flat or nested results. byte_ranges() adds a request-object form for index-heavy readers, opendal_bytes_slice() derives subrange OpendalBytes handles without first materializing full R raw vectors, and as.raw.OpendalBytes() now returns a raw ALTREP facade that supports element and region access before R-owned raw-vector materialization.
• Byte stores: byte_store() and store_*() helpers provide a small store-relative key-to-bytes adapter for Zarr-like chunk layouts. store_read() is now bytes-first for OpendalBytes/ALTREP-compatible flows, async store_*_aio() wrappers are available, store_cache() adds an explicit local full-object cache for chunk-key stores, and store_block_cache() adds an explicit local fixed-size cache for scalar result = "auto" complete/range store reads. New vignettes and tests show pure-R chunked-array and indexed range-reader patterns on top of the byte substrate.
• API: R-side batch_concurrency = 0 is now rejected; use NULL for the default. Capability rows now include range/concurrency/recursive semantics.
• C API: write tuning options are wired through, unsupported write header options reject explicitly, ropendal_aio_wait() honors its timeout, callbacks now receive the completed Aio pointer, and prefix-scoped byte stores now expose async read/write/read-into/list/delete plus explicit full-object and fixed-size block cache adapters for downstream native code. The C ABI version is now 4.

Ropendal 0.0.1

• Initial public release.
• Added byte-first filesystem primitives backed by Apache OpenDAL, including read, write/create, replace, append, stat, listing, copy, rename, delete, and directory creation where supported by the backend.
• Added Aio-based async operations and controls, including fs_*_aio(), call_aio(), collect_aio(), unresolved sentinels, condition variables, and monitor helpers.
• Added explicit serializer/deserializer and codec layers for materializing R objects and transforming raw bytes.
• Added an async-first native C API in inst/include/ropendal.h for downstream native packages that need direct byte I/O into caller-owned buffers.
• Added local filesystem, HTTP(S), S3-compatible, and Google Drive examples and test coverage.
