Roo Code 3.48.1 Release Notes (2026-02-18)

This release fixes the Bedrock Claude Sonnet 4.6 model ID, resolves MCP tools being unavailable on the first task turn, and patches IPC queue handling.

Bug Fixes

  • MCP Tools Unavailable on First Turn: Fixes an issue where MCP tools were missing from the system prompt on the very first API call when a task was started via IPC. The MCP server manager now awaits all server connections before returning the hub, so tools appear correctly from the start. (#11518)
  • IPC Queue Message Deletion: Fixes an issue where messages deleted from the Roo Code Cloud queue were still being processed by the extension internally. The IPC protocol now supports a true DeleteQueuedMessage command so deleted messages are fully dropped rather than silently re-processed on dequeue. (#11464)
  • Package Metadata Version Regression: Fixes an internal package metadata version that was incorrectly rolled back by a prior revert, which would have caused the next @roo-code/types npm publish to fail. (#11588)

Provider Updates

  • Bedrock Claude Sonnet 4.6 Model ID: Fixes an incorrect model ID for Claude Sonnet 4.6 on Amazon Bedrock (anthropic.claude-sonnet-4-6-20260114-v1:0 → anthropic.claude-sonnet-4-6), including the 1M context and global inference variants that were also affected. (thanks PeterDaveHello!) (#11569)
