# Roo Code 3.48.0: browser use and built-in skills removed, Sonnet 4.6 support added

> A large release that both adds and deletes surface area. Claude Sonnet 4.6 is supported across Anthropic, Bedrock, Vertex, OpenRouter and Vercel AI Gateway, and GLM-5 lands on the Z.ai provider. On the removal side, browser use, the built-in skills mechanism, file-based system prompt override (footgun prompting) and nine low-usage providers are gone, and the `search_and_replace` tool is renamed to `edit`. Anyone relying on those features or on scripted tool names must change their setup.
