AI Summary

Introduces async text extraction for Node.js and significantly optimizes underline/strikeout detection performance.

Key Highlights

  • Linux binary compatibility restored for Amazon Linux 2023.

New Features

  • Async text extraction API.
  • Performance optimization for underline detection.
  • Binary compatibility fixes.

Full Release Notes

Changes since 1.24.0:

- Node: `extractTextWithPositionsAsync`, the async variant of `extractTextWithPositions`: the same arguments and items, run on the libuv thread pool so a slow page no longer blocks the caller's event loop (#592).
- Underline and strikeout detection no longer takes quadratic time on pages drawn from many thin filled rects or short strokes: a page of about 200,000 thin rects went from about 40 s to under 0.5 s, with the same marks (#592).
- The `linux-x64-gnu` Node binary is cross-built for a GLIBC_2.17 floor again, so it loads on Amazon Linux 2023 (the managed AWS Lambda Node runtimes), RHEL 9 and Debian 11 (#586).

API: Node `extractTextWithPositionsAsync`.

Release preparation: #593.
