This update is all about making the command-line tool more reliable when talking to its server. If you use this tool to generate long responses or if you deal with a flaky internet connection, this update means the app will fix itself instead of just freezing up and making you restart.
What's new
- Automatic recovery from network hiccups: If the server slows down or drops your connection, the tool will now automatically wait a bit and try again (this is called "backoff") instead of just crashing.
- Idle warnings and timeouts: The app now has a built-in timer (a "watchdog"). If the server goes totally quiet for 60 seconds, it will warn you. If it stays quiet for 5 minutes (300 seconds), it cancels the request so your screen doesn't freeze forever.
- Support for really long answers: By default, the tool will now wait up to 60 minutes for a response. Before, if an answer took too long to generate, it might get cut off. Now, long answers have plenty of time to finish. You can adjust these timers yourself using the settings mentioned in the notes.
Improvements
- The tool is much better at handling "5xx errors" (which are server-side crashes). Instead of failing right away, it automatically retries the request.
Fixes
- Fixed an issue where the tool would hang forever if a response stream (the data flowing from the server to your screen) stalled out.
