Sourced from oneio's releases.

v0.22.0

Breaking changes

• Migrated S3 implementation from rust-s3 to rusty-s3 (sans-IO signing + reqwest HTTP)
  • s3_bucket() now returns S3Bucket instead of rust_s3::Bucket
  • s3_stats() now returns S3ObjectMetadata instead of rust_s3::serde_types::HeadObjectResult
  • Removed re-export of rust-s3 types; all S3 types are now owned by oneio
• s3_list() keeps returning Vec<String> for backward compatibility

Changed

• S3 operations now use the same reqwest HTTP client as HTTP operations (no duplicate HTTP stack)
• Single PUT uploads for files smaller than the multipart threshold (default: 5MB)
• Multipart uploads use 8MB chunks with auto-calculated part sizing for very large files
• S3Config is now a public type with endpoint/region fields
• Added ONEIO_S3_MULTIPART_THRESHOLD environment variable to configure when to use multipart upload (default: 5MB, the S3 minimum part size)

Bug fixes

• Fixed s3_copy() to use AWS Signature V4 Authorization header for S3-compatible services like R2
• Fixed digest command to work with remote URLs (HTTP, HTTPS, FTP, S3)
• Fixed s3_list() to decode URL-encoded keys returned by ListObjectsV2
• Fixed oneio s3 list CLI flag parsing by removing the -d short-flag collision

v0.21.0 -- 2026-03-27

Breaking changes

• OneIoError is now #[non_exhaustive]; match expressions without a wildcard _ arm will fail to compile
• OneIoBuilder::header() now accepts typed HeaderName/HeaderValue (infallible) instead of (K, V) -> Result<Self>
• OneIoBuilder::user_agent() now accepts a typed HeaderValue (infallible) instead of V -> Result<Self>
• oneio::download() no longer accepts an Option<reqwest::blocking::Client> parameter
• oneio::remote module is now pub(crate); create_client_with_headers is deprecated (use OneIo::builder().header_str())
• ProgressReader and ProgressCallback are no longer part of the public API

Changed

• Flattened module layout: src/oneio/ sub-directory removed; all modules are now at src/ level
• OneIo and OneIoBuilder are now the primary API surface; free-standing functions delegate to a shared default client
• Compression detection strips URL query parameters and fragments before reading the file extension
• download_with_retry() uses exponential backoff between retry attempts (100ms × 2^attempt, capped at 6400ms)
• Stream cache writes to disk via std::io::copy instead of buffering the full payload in memory
• download_async() now preserves raw bytes, matching download()
• Default blocking HTTP clients are reused across reads and content-length probes
• Stateless read and download helpers now delegate to a reusable OneIo client internally
• S3 status failures now use structured errors instead of string parsing
• S3 readers now stream data through a bounded channel instead of materializing the full object in memory

Added

• OneIoBuilder::header_str(name, value) — string convenience for adding headers (panics on invalid input, matching reqwest convention)
• OneIoBuilder::configure_http(f) — escape hatch for setting any reqwest::blocking::ClientBuilder option
• OneIoBuilder::timeout(), connect_timeout() — request and connect timeouts
• OneIoBuilder::proxy(), no_proxy() — proxy configuration
• OneIoBuilder::redirect() — redirect policy
