Conversation
## Motivation and Context `lib/mcp/transports/stdio.rb` was a deprecated shim that redirected users from `MCP::Transports::StdioTransport` to `MCP::Server::Transports::StdioTransport`. It has been 10 months since the migration path was introduced, providing sufficient time for users to update their code. ## How Has This Been Tested? All tests pass (`rake test`), and no code in the repository references `MCP::Transports` or `mcp/transports/stdio`. ## Breaking Changes `require "mcp/transports/stdio"` and `MCP::Transports::StdioTransport` are removed. Use `require "mcp/server/transports/stdio_transport"` and `MCP::Server::Transports::StdioTransport` instead.
