Runtime changelog, 10 November 2026

What shipped in Runtime Cloud on 10 November 2026: new accounts add credit before their first sandbox; and the Go, Python, Ruby and Java SDKs try a hostname's next address when a connection attempt fails or stalls.

New accounts add credit before their first sandbox

A new account now runs sandboxes once it holds credit, from $10. Credit added within 30 days of signing up is still matched, up to $1,000 in total, so a first $10 becomes $20. Once an account has paid, it still gets 100 free hours of a 1 GB machine every calendar month. Accounts given free hours or free usage before 10 November 2026 keep what is left of them. A first sign-in with Google now passes the same human check as an email sign-up before it creates a company; people who already have an account are not asked. See included usage and welcome match.

The Go, Python, Ruby and Java SDKs try a hostname's next address when a connection attempt fails or stalls

Previously each SDK connected to the first address DNS returned for the API and returned an error if that address did not answer. Now, when a connection attempt fails, or has not completed after 250 ms, the SDK starts an attempt to the hostname's next address and uses whichever connects first. This applies to API requests, WebSocket connections and proxied connections. Behavior is unchanged when the hostname resolves to a single address. Available in the next patch release of each of these SDKs; no code change is required.
