Version 3.18.0

2026-07-21

• Fix: Use wide character APIs to better support of non-UTF-8 filesystems on Windows.
• Fix: Don't crash in AssetFileSystem.exists() when the underlying storage throws a FileNotFoundException.
• Fix: Load WASI paths relative to their preopen. The platform behavior recently changed in NodeJS, causing our WasiFileSystem to be unable to access files!
• New: Optionally ignore whitespace when decoding hexadecimal.
• New: Optionally omit padding when encoding Base64.
• New: BufferedSource.readUInt(), BufferedSink.writeUInt(), and similar functions for UByte, UShort and ULong. Also add support for unsigned and little-endian.
• New: BufferedSink.utf8Appendable(). Use this to adapt an Okio sink to an Appendable.
• New: Source.limit() returns a wrapped source with a strict limit on how many bytes are returned.
• New: ByteString.equals(other, constantTime) for subtle defense against timing attacks.
