> [!NOTE]
> **Low Risk**
> Version and release-documentation updates only; no code changes in the
PR diff.
> 
> **Overview**
> **Release Please** bumps **LaunchDarkly.ClientSdk** from **5.8.0** to
**5.9.0** across the release manifest, `LaunchDarkly.ClientSdk.csproj`,
`CHANGELOG.md`, and `PROVENANCE.md` verification examples.
> 
> There are **no runtime or SDK source changes** in this diff. The
release notes call out **per-context summary events**
([#288](#288)), which
enables analytics summary events scoped per active context rather than
aggregated differently—already implemented elsewhere on the branch (e.g.
`PerContextSummaries` in event processor configuration).
