4.21.1
(chore): Bump bundled @fern-api/generator-cli to 0.10.1. Auto-versioned MAJOR/MINOR bumps no longer
produce a version-only changelog.md block when the AI analysis returns an empty changelog
entry; the PR description, version bump reason, or commit message body is used instead.
4.21.0
(feat): Generated root clients (sync and async) now implement AutoCloseable. close() shuts down
the underlying OkHttpClient’s dispatcher executor and evicts its connection pool, but only
when the SDK created that OkHttpClient itself — a client supplied via Builder.httpClient(...)
is left running, since the caller owns its lifecycle. This lets short-lived applications (e.g.
CLIs, or code that finishes after using WebSockets) release the client’s background threads
instead of relying on JVM shutdown.
