Roo Code v3.36.15 Release

Vertex AI: 1M context window for Claude Sonnet 4.5​

When you use Claude Sonnet 4.5 on Vertex AI, you can now enable a 1M context window option for supported models (#10209).

Chat error troubleshooting improvements​

Chat error states now make it easier to understand what went wrong and to share the right details when filing a bug report:

  • Clearer error visibility: Error rows more consistently surface full error details (including status codes) via a more obvious View details affordance (#10204)
  • Downloadable diagnostics: You can generate a local diagnostics file from a chat error (including error metadata and the API conversation history) so you can review/redact and share it with an issue report (#10188)

Bug Fixes​

  • Native tool calling support for LM Studio and Qwen-Code: Fixes an issue where these providers were missing OpenAI-style native tool call support, which could make tool use unreliable compared to other providers (#10208)
  • More reliable tool defaults for OpenAI Compatible providers: Fixes cases where tool calling could be inconsistent unless you manually adjusted custom model info, by applying native tool defaults unless you’ve explicitly overridden them (#10213)
  • Requesty native tool calls enabled: Fixes native tool calling defaults for the Requesty provider (and aligns behavior for Unbound) so tool use is more consistent, especially when model metadata is cached (#10211)
  • Strict JSON Schema compatibility: Fixes an issue where some MCP tool schemas could fail strict validation due to missing additionalProperties: false on object schemas (#10210)
  • Refresh models cache reliability: Fixes an issue where Refresh models could fail to fully flush/refresh cached model lists for some providers, and improves correctness of initial model selection when starting a new task (#9870)
