# v0.1.0-alpha.32 14/04/2026

***

**Description**: Two replicas by default; explicit error when Tansu lacks S3 retention.

### Changes

* Default to 2 data-plane replicas; bump `metrics-exporter` and chart (#2006).
* Surface an explicit error if Tansu is enabled but S3 retention is not provided.
* Remove the dedicated preprod / prod overlays for `metrics-exporter` (now bundled in the chart).
