## What’s Changed

- **Bump the Bitrise Build Cache CLI to v3.9.0.** Both halves of a React Native build now report per-blob cache transfer stats — latency, blob size and throughput as histograms, plus exact throughput percentiles. Android gets it through the Gradle plugins (`gradle-analytics 3.3.0`, `remote-cache 2.2.0`), iOS through the xcelerate proxy, and the C++/ccache side through the ccache storage helper.

- **`--cache-push` now defaults to on.** React Native activation previously defaulted the local cache to pull-only, so nothing was stored and early builds showed zero uploads and no hits. Pull-only is still available with `--cache-push=false`.
