Release Notes

web-speedtest 1.1.0 — 28 Oct 2026

Built with Go 1.27.3 to pick up the fix for the eMudura TLS issue.
go.mod now requires Go 1.27.3 (was 1.25.0), so builds from source can't fall back to an older toolchain without the fix. This also brings in Go 1.27's default runtime (GODEBUG) settings, including its current TLS defaults.

Moved to new GitHub location: https://github.com/WaterJuice/web-speedtest

Initial release
Server mode — HTTP server with embedded web UI for browser-based speed testing
Client mode — CLI tool that measures ping, download, and upload from any web-speedtest server
Web UI with animated gauges, dark theme, and live progress
Copy test results from the web UI to the clipboard as text or as a PNG image
WebSocket ping for low-overhead latency measurement, with HTTP fallback
Server-Timing header on the HTTP ping endpoint so the CLI client can subtract server processing time
Warmup exclusion (first 2 seconds discarded) for download/upload accuracy
Median-based ping reporting for outlier robustness
Parallel streams (6) for both download and upload tests
Hand-rolled WebSocket implementation (RFC 6455) — stdlib only
API endpoints: /api/ping, /api/download, /api/upload, /api/info, /ws
Beta ribbon shown automatically on pre-release builds, hidden on full X.Y.Z releases
Single statically-linked Go binary with zero runtime dependencies
Distributed as platform-specific Python wheels via PyPI (using bin2whl)
Cross-platform: macOS, Linux, and Windows on both arm64 and amd64
