This release is a maintenance update for people using Cline's SDK bundle (a software package that lets developers build apps on top of Cline). It focuses entirely on fixing bugs to make sure custom AI models, server connections, and tracking tools work smoothly.
Fixes
- Custom AI models can use tools again: Some developers use custom, OpenAI-compatible AI models. Cline was accidentally reading a shortcut setting (
supportsReasoning) as a strict "no" and stripping away the AI's ability to use tools. This update fixes that glitch so the AI can use its tools properly again. - Sessions survive server restarts: If you were using a "Hub-backed session" (a workspace hosted on a central server) and that server restarted or updated, you used to risk losing your place or seeing duplicate messages. Now, when the server comes back online, the software safely replays anything you missed without repeating messages.
- Better tracking logs: Developers use tools like Langfuse to track and debug what the AI is doing. Previously, when tracking Hub-backed sessions or delegated-agent runs (tasks handed off to other AI helpers), the logs were missing important context. They now correctly show exactly which session they belong to and what software version was used.
