A launch is worth your time if it changes the next thing you type. Iroh 1.0 does. If you build on it, delete host:port first [C002]. This is not mainly a faster-pipe story. It is an address story.
If you mostly use ChatGPT/Claude-style tools and are just starting to track new infrastructure, this is the part that matters. The easy mistake is to read Iroh 1.0 [C001] as "better P2P plumbing" and keep scrolling. That wastes time, because the change lands earlier than performance: it changes what your app points at.
Most launch posts sound useful but change nothing. A launch is worth your time if it changes the next thing you type. The June 15, 2026 launch post says "Dial Keys, not IPs." That is the signal. It means: call the device identity first, not a machine address that can change.
The README makes the consequence more concrete: you aim at a device key, and Iroh finds and keeps the fastest working connection. That is why this is bigger than "faster direct links." The app model changes before the speed story does.
The docs push the same point lower down the stack: each node gets a stable EndpointID, basically a durable name, while Iroh handles address discovery, router barriers, and relay fallback underneath. Docs-only boundary: this is based on the June 15 launch post, README, and official docs, not a live speed or network test. Share this with anyone about to hard-code host:port into an Iroh app.
