Cline v4.1.17 Changelog

What's new

• ClinePass is everywhere now: You'll see new cards, hints, and banners explaining your ClinePass subscription throughout the app. If you dismiss a banner, it stays dismissed.
• More ways to use global rules: If you use Windows Subsystem for Linux (WSL) or run the app without a screen, the app now correctly reads your custom rules from the ~/Cline/Rules folder.

Improvements

• Smoother rejection messages: When you tell the AI not to use a specific tool, the system now tells the AI that you actively chose to block it, instead of making it look like a random computer error.
• Live model catalog: The app now reads the list of AI models live from the internet. This means when the creators add new AI models, you'll see them right away without needing a separate app update.
• Massive model list refresh: The app added ten new AI providers (like Bothub, Volcengine Ark, and TokenRouter). Because of this, if you use a provider without specifically choosing a model, the default AI has changed for 57 providers. Most notably, the default for Anthropic is now Claude Fable 5.1 instead of Claude Opus 5. If you don't want it to change, make sure you specifically pick a model.
• Faster startup with remote servers: If you use remote MCP servers (external tools that talk to your app over the internet), they no longer freeze the app for a long time when starting up. The app now gives up trying to connect after 10 seconds.

Fixes

• Fixed a massive memory leak: During long tasks, the app's background process was sending the entire conversation history to every connected window every time there was an update. This could make the app eat tens of gigabytes of memory and crash. It now only sends the current state, saving tons of memory.
• Stopped hook script crashes: If a custom background script failed to start, it used to crash the entire app and ruin your running task. Now, the app stays alive.
• Fixed chat crashes: The chat window no longer crashes if it gets bad data about an API request.
• Fixed hidden costs: Cost estimates no longer show up in your history if you are using a subscription plan (like ClinePass or ChatGPT via Codex), so it matches the task header.
• Fixed sneaky API key errors: Sometimes copying a password adds invisible characters (like extra spaces or hidden lines) that the text box hides. This made it look like you typed a wrong password. The app now cleans these invisible characters and gives a clear error if the key is the problem.
• Better OpenAI Codex sign-in: When signing into ChatGPT/Codex, if the required network port (1455) is already being used, you now get a clear error instead of a blank browser tab. Other sign-in errors now show the real reason instead of a generic "missing code" message.
• No more random logouts: A tiny network hiccup while refreshing your login token no longer signs you out. You only get logged out if your token is genuinely rejected.
• Restored tool use for some AI models: Some AI models (like Dify, SAP AI Core, opencode, and Codex CLI) had their abilities to use tools turned off by mistake because an empty list was read as a strict "no." Tools now work for them.
• Images no longer dropped: The app no longer drops images when reading files on models that lack a specific capability list.
• Safer file restores: If you try to go back to an old save point (a checkpoint) after making new saves, the app stops you instead of quietly deleting your new work.
• Line ending fix: The file-patching tool now keeps Windows-style line endings (CRLF) instead of changing them.
• Aborting tasks cancels helpers: Hitting "stop" on a task now actually stops the background helper agents too, rather than leaving them running.
• Fixed tracking tools: Telemetry (data tracking) for background tasks and Langfuse tracing now actually work in the official downloaded app. A code-shortening process had broken them before.
