 - Cache the result of `cider--running-nrepl-paths` (used by `cider-locate-running-nrepl-ports`) for `cider-running-nrepl-paths-cache-ttl` seconds (default 5). Repeated `cider-connect` completions no longer re-spawn a fresh round of `ps`/`lsof` subprocesses each time. `cider-clear-running-nrepl-paths-cache` discards the cache on demand.
 - New `nrepl-make-eval-handler` with a keyword-arg API (`:on-value`, `:on-stdout`, `:on-stderr`, `:on-done`, `:on-eval-error`, `:on-content-type`, `:on-truncated`). Sub-handlers no longer take a buffer argument -- they close over whatever they need. `nrepl-make-response-handler`, the legacy 7-positional-arg form, is preserved as an obsolete shim that adapts the old (buffer x) lambdas to the new (x) lambdas, so existing extensions keep working.
 - New `cider-repl-history-doctor` command: walks `cider-repl-input-history` looking for entries whose parens don't balance under Clojure syntax, shows each in a side buffer, and asks whether to delete it.  When done, rewrites `cider-repl-history-file` if one is configured.  Useful for cleaning up history after a typo got committed that breaks `cider-repl-history` rendering (see [#3915](https://github.com/clojure-emacs/cider/issues/3915)).
+- Recognize [let-go](https://github.com/nooga/let-go) (a Clojure dialect implemented in Go) as a known nREPL runtime.  `cider-runtime` returns `let-go` for these connections and the connection info line shows the runtime version, e.g. `CLJ project@localhost:2137 (let-go 1.0)`.
 - Decouple the nREPL transport layer from CIDER's UI layer (closes [#1099](https://github.com/clojure-emacs/cider/issues/1099)). `nrepl-make-eval-handler` is now CIDER-agnostic: it no longer references `nrepl-namespace-handler-function`, `nrepl-err-handler-function`, `nrepl-need-input-handler-function`, or any hardcoded UI strings. New `:on-ns` and `:on-status` keyword slots let any consumer wire up their own namespace tracking and status handling. The editor-level `cider-make-eval-handler` wraps it with CIDER's UI behavior (ns tracking, default error handler, need-input prompt, "Evaluation interrupted." / "Namespace not found." messages); in-tree callers all use it.
