This release focuses entirely on fixing connection bugs related to MCP (Model Context Protocol, a way for AI to connect to outside tools). If you use Devin to connect to tools like Figma through a secure network proxy or gateway, these fixes make sure the sign-in process actually works.
Fixes
- Custom headers during sign-in: Previously, if a server needed special security codes (called HTTP headers) to let you in, those codes were getting lost during the sign-in step. Now, they are passed along correctly so you can log in successfully.
- Proxy confusion with built-in logins: Devin has built-in shortcuts to log into tools like Figma. Before, it got confused if you connected through a proxy (a middleman server) and looked for the wrong login details. Now it looks for the correct "issuer" (the actual company handling the login) instead of just the middleman's name, so it finds the right login method.
