What's new in 3.0.5
GreenTunnel v3 is out now.
A ground-up TypeScript rewrite: a new engine with real backpressure and timeouts, RFC 8484 DoH and DoT, a system-proxy layer that snapshots your settings and puts them back — even after a crash — and a rebuilt Electron app with a live log panel.
Runtime dependencies are down to two. yargs, chalk, ora, debug, dns-socket, validator and winreg are all gone, replaced by things Node ships with.
Open-source tools that help people reach the free internet shouldn't die — and with AI-assisted development, they don't have to. We'll keep doing our best to help people access the open internet, one packet at a time.
