Cline v4.1.21: a new default model for 19 providers

In Cline 4.1.21, nineteen providers that don't pin a model now resolve to a different default. If you use one of them without choosing a model, your next task runs on a new one.

These local servers stop generating once the context window is full, whatever output budget you set. On a long session, that limit used to end the task in the middle of an answer.

CHANGELOG.md · 4.1.21

Now, when a local model hits that output limit, Cline compacts the conversation to free up room and retries the reply once, so the task keeps running.

When there's nothing left to compact, the existing recovery takes over and asks the model to answer more concisely. Either way, you keep the partial answer it already wrote.

When a model sends back an empty response, Cline waits and then retries. Cancelling during that wait now stops the request right away, instead of after the backoff finishes.
