v0.2.0

Added

• Bounded retry with exponential backoff for transient GitHub API failures (404, 5xx, 429, and 403 when the error message indicates rate limit or abuse), configurable via MAX_ATTEMPTS and CommitOptions (maxAttempts, logger, optional baseDelayMs / maxDelayMs); new retry module helpers isTransientError, classifyError, calculateDelay, and withRetry (issue #20).
• Efficient multi-file commits via GitHub createTree inline content for text files (blobs created server-side), createBlob only for binary files (NUL detected in the first 8 KiB), and chained createTree requests in chunks of TREE_ENTRY_CHUNK_SIZE (100) entries for very large change sets and payload limits (issue #19).

Changed

• README Action example uses a tagged release (@v0.1.5) instead of @main for reproducibility; unreleased behavior remains documented in the same section.
• Exported helpers for library use: isBinaryFile, getFileMode, and TREE_ENTRY_CHUNK_SIZE from commit.ts.
• Binary blob creation is now sequential instead of concurrent to avoid secondary rate-limit bursts.

Fixed

• withRetry could surface undefined when maxAttempts was non-positive or non-finite; values are now normalized to at least one attempt.
• HTTP-like error detection for retries now requires status to be a number (avoids misclassifying odd error shapes).
• Non-UTF-8 text fallback in createTree delegates to createBlob() so blob behavior stays consistent.
• isBinaryFile false positives when readSync returns fewer bytes than requested (zero-filled buffer tail).
• Silent data corruption for non-UTF-8 text files by validating with TextDecoder({ fatal: true }) and falling back to createBlob.
