# Roo Code 3.35.4 Release Notes (2025-12-02)
12

+
This release fixes a tool call handling regression, simplifies the write_to_file tool, and corrects z.ai provider UI.
14
+
15
+
## QOL Improvements
16
+
17
+
***Simplified write_to_file Tool**: The `line_count` parameter has been removed from the write_to_file tool, making tool calls cleaner and reducing potential errors from incorrect line counts ([#9667](https://github.com/RooCodeInc/Roo-Code/pull/9667))
18
+

+
## Bug Fixes
20
+
21
+
***Malformed Tool Call Fix**: Fixed a regression where malformed native tool calls would cause Roo Code to hang indefinitely. Tool calls now proceed to validation which catches and reports the missing parameters properly ([#9758](https://github.com/RooCodeInc/Roo-Code/pull/9758))
22

+
## Provider Updates
24
+
25
+
***z.ai GLM Model Fix**: Removed misleading reasoning toggle UI for GLM-4.5 and GLM-4.6 models on z.ai provider, as these models don't support think/reasoning data for coding agents ([#9752](https://github.com/RooCodeInc/Roo-Code/pull/9752))
