 - `nrepl-client-sentinel` now tears down the SSH tunnel buffer/process when the client connection closes. Previously only the orderly `cider-quit` path killed the tunnel, so an abnormal disconnect (server crash, network drop) left the `ssh` subprocess as a zombie until Emacs exited.
 - Bound `nrepl-completed-requests` with a FIFO cap (`nrepl-completed-requests-max-size`, default 1000). The completed-request handler table previously grew unbounded for the lifetime of a connection; long-running sessions accumulated thousands of stale handler closures.
 - [#3909](https://github.com/clojure-emacs/cider/issues/3909): `cider--sesman-friendly-session-p` is more robust at attaching buffers to existing sessions. The classpath and namespace caches are now populated eagerly at connection time instead of lazily on first sesman call (previously a nil/empty result was indistinguishable from "not cached" and was re-fetched on every check). The matcher is now a pure path comparison and never blocks on the REPL. Beyond the caching fix, it also falls back to the connection's `nrepl-project-dir` when classpath matching fails, uses `file-in-directory-p` for classpath-root boundary checks (avoiding spurious prefix matches like `/foo/bar` against `/foo/barber/...`), and short-circuits to the chosen session when `cider-default-session` is set.
+- `nrepl-bencode` no longer crashes when handed a non-string scalar (symbol, float, etc.). The documented fallback ("everything else is encoded as string") used `string-bytes` directly, which errors on non-string input; values are now coerced via `format' before measuring byte length.
