The latest version of the LSP protocol introduces a number of changes. It is now possible to indicate partial results and progress. request.ts had to construct some new types (at the end of tsclient.go and tsserver,go) to avoid using a struct for a formal parameter type. Also, instead of using the same type for many RPCs, most RPCs now have their own types.
