Changes in version 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. Changes in version 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.
