 Follow the guide that matches your upgrade, one minor at a time:
 
+- **[v1.2 to v1.3](./v1.2-to-v1.3.mdx)** — no backward-incompatible changes yet; follow the standard process.

 - **[v1.0 to v1.1](./v1.0-to-v1.1.mdx)** — no backward-incompatible changes; the standard process plus observability-module version bumps.
