> [!NOTE]
> **Low Risk**
> Version and documentation-only release PR with no runtime code changes
in the diff.
> 
> **Overview**
> **Release Please** cut for **9.16.1**: version identifiers move from
`9.16.0` to `9.16.1` in `.release-please-manifest.json`,
`ldclient/version.py`, `pyproject.toml`, and the provenance example in
`PROVENANCE.md`.
> 
> `CHANGELOG.md` gains a **9.16.1** section that records what ships in
this patch (already merged elsewhere): dependency bump for
**python-eventsource** / connection pool teardown, **data source error
reporting** fixes, removal of dead **`__BUILTINS__`**, and **docs**
clarifying `is_initialized()` semantics. The PR diff itself is release
metadata only—no SDK source changes beyond version strings.
