What changed
Cloud sessions run in hosted sandboxes, keep going after you close the editor, and show up in Recent and History with notifications. The same release switched the default Cline-provider model to Gemini 4 Argon; version 4.1.26 on October 26 switched it back to Claude Sonnet 5.5.
Who it affects
Cline extension users.
What to do
Turn on cloud sessions in Settings, and pin a model if you rely on the provider default.
