Summary

LibreSpeed 6.2.0 adds a dedicated connection-stability test and installable PWA support, improves multi-server selection behavior, and makes the Docker images reliably accept the default 20 MiB upload chunks.

Highlights

  • Added stability.html, a standalone connection-stability test with live latency metrics and charting, packet-loss tracking, optional alerts, and CSV export.
  • Added PWA metadata, manifest, and application icons so LibreSpeed can be installed from supported browsers.
  • Improved multiple-point server-list sorting and handling of duplicate or qualified city names.
  • Docker images now set PHP post_max_size = 32M, preventing the default 20 MiB upload chunks from being rejected.
  • Updated the Alpine Docker image base to Alpine 3.24.

Fixes

  • Fixed stability-test server selection, timeouts, and failed-request reporting.
  • Fixed a race when starting a selected server test.
  • Included PWA assets in the npm package.
  • Improved Docker PHP configuration discovery and startup behavior.

Breaking Changes

None.

Migration Notes

No action is required for Docker users. Non-Docker PHP deployments must continue to allow POST request bodies of at least 20 MiB; post_max_size = 32M is recommended. Reverse proxies must permit the same request size.

Maintenance

  • Updated GitHub Actions dependencies.
  • Refreshed documentation and minor code comments.
