This update is for anyone who uses the Devin Command Line tool to connect to external helper programs. If you updated recently and lost your connection, this release fixes that problem so you can get back to work.
Fixes
- Fixed a bug introduced in the previous version that broke connections to MCP servers using Streamable HTTP. "MCP servers" are external helper programs that add extra skills to the tool, and "Streamable HTTP" is a method for sending data back and forth over the web. A recent update accidentally broke this communication link, and this patch repairs it so they connect smoothly again.
