v1.2.0

[1.2.0] - 2026-02-12

Added

• SharedArrayBuffer support (zero-copy) for all encoding functions
• AllowSharedBufferSource input type across the public API (DataSource, decodeUtf8, bufferSourceToBytes)

Changed

• DataSource type widened from string | BufferSource to string | AllowSharedBufferSource
• bufferSourceToBytes return type simplified from Uint8Array<ArrayBuffer> to Uint8Array

v1.1.0

[1.1.0] - 2026-02-09

Added

• EncodeBase64Options interface (alphabet, omitPadding) for encodeBase64()
• DecodeBase64Options interface (alphabet, lastChunkHandling) for decodeBase64()
• Input validation for decodeByteString and decodeHex
• Native Uint8Array.fromBase64 / Uint8Array.prototype.toBase64 and Uint8Array.fromHex / Uint8Array.prototype.toHex (ES2026) detection with pure JS fallback

Fixed

• decodeBase64Fallback byte length calculation and validation

Changed

• Always prefer native APIs when available, removed all fallback thresholds
• Switched encodeByteString to chunked String.fromCharCode.apply for large inputs
• Replaced runtime hex parsing with pre-computed lookup tables
• UTF-8 encode fallback: replaced dynamic array with pre-allocated Uint8Array
• UTF-8 decode fallback: switched from code-point array to pre-allocated Uint16Array
• UTF-8 decode: skip BOM at byte level instead of post-decode string strip
• Extracted shared typedArrayToString helper and APPLY_CHUNK constant into internal module
• Standardized input validation and error types across all decode functions
• Improved dataSourceToBytes type guard and cleaned up internals
