+
+## Bug Fixes

 * **Apply Diff Accuracy**: Fixed start line parameter not working correctly when applying multiple file diffs (thanks samhvw8!) ([#5019](https://github.com/RooCodeInc/Roo-Code/pull/5019))
 * **Ollama Compatibility**: Resolved validation errors that prevented Ollama from working with certain models (thanks daniel-lxs, MartinHarding1998!) ([#5014](https://github.com/RooCodeInc/Roo-Code/pull/5014))
 *   **Ollama & LM Studio Context Length**: The context length for models served by Ollama and LM Studio is now automatically detected and displayed correctly, so you no longer need to configure it manually (thanks thecolorblue, Fade78!) ([#4314](https://github.com/RooCodeInc/Roo-Code/pull/4314)).
