<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> **Medium Risk**
> Ships opt-in FDv2 flag delivery and connection-mode behavior; default
FDv1 paths are unchanged, but adopters of `dataSystem` hit an Early
Access API and new networking semantics.
>
> **Overview**
> Release Please version cut that publishes **FDv2 / data saving mode
Early Access** across the client SDK family by bumping
`@launchdarkly/js-client-sdk-common` to **1.29.0** and cascading
dependency updates.
>
> **`@launchdarkly/js-client-sdk` 4.9.0** and
**`@launchdarkly/react-native-client-sdk` 10.19.0** document opt-in via
`dataSystem: {}` (FDv2); apps without `dataSystem` keep FDv1.
Browser/React Web use streaming with polling fallback and manual
`automaticModeSwitching` only; React Native defaults to foreground
streaming / background polling with lifecycle-based mode switching
unless disabled.
>
> **`@launchdarkly/react-sdk` 4.1.2** picks up the browser SDK and
documents the same opt-in through `ldOptions.dataSystem`. Wrapper
packages (`@launchdarkly/browser`, `node-client-sdk`,
`client-testing-plugin`, `@launchdarkly/jest`) and examples only update
pinned versions and changelogs; there is no new runtime code in this
diff beyond release stamps (e.g. `BrowserInfo`, `PlatformInfo`,
`LDReactClient` wrapper version).
