v1.4.2

Fixed

• Idle agent sessions are less likely to be dropped by a reverse proxy. The MCP SDK was updated
  to 1.30.0, whose Streamable HTTP server transport now emits SSE keep-alive comment frames (and
  fixes the keep-alive timer's lifecycle) — an agent that sits idle between tool calls no longer
  looks like a dead connection to an intermediary that times out silent streams, which showed up as
  a session vanishing mid-conversation. The same bump tightens Content-Type validation to parse
  the media type instead of substring-matching it, and bounds the read buffer for stdio servers that
  emit very large responses.
