## Rewrite in TypeScript with backward compatibility

_v2.0.0 · 2026-08-05_

TypeScript rewrite with Node 24 fixes, optimized compression, and bounded concurrency limits.

### What changed

Complete TypeScript rewrite of the codebase. All v1 commands remain functional and deprecated (not removed), ensuring existing scripts continue to work without breaking changes.

Resolved critical defects discovered during security audit, including crashes that occurred within minutes of running v1 on Node 24.

Corrected video encoding logic that was producing wrong output formats.

Implement concurrency controls to prevent unbounded resource usage during bulk compression operations.

Refactored image compression logic in src/image.js for improved efficiency and output quality.

Enhanced video compression output and logging in src/video.js.

Restructured cli.js, src/index.js, and utils/fns.js for better maintainability and clarity.

Documentation improvements across multiple PRs.
