@@ -13,6 +13,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - Add an optional `required` field to `MethodSchema` (mirroring `required` on object `JsonSchema`) naming which arguments are required, and a `{ required }` option on `methodArgsToStruct` that validates unlisted arguments as optional, so a method's argument schema can faithfully represent the optional trailing arguments its guard already allows ([#958](https://github.com/MetaMask/ocap-kernel/pull/958))
 - Add `getLibp2pRelayHome()` to the `./nodejs` exports, returning the libp2p relay's bookkeeping directory (default `~/.libp2p-relay`, overridable via `$LIBP2P_RELAY_HOME`) — kept separate from `$OCAP_HOME` so one relay can serve daemons with different OCAP_HOMEs ([#952](https://github.com/MetaMask/ocap-kernel/pull/952))
 - `startRelay()` accepts an optional `publicIp` that is fed to libp2p's `appendAnnounce`, so a relay running on a NAT-backed host can announce its publicly-reachable IPv4 alongside its bound NIC addresses ([#952](https://github.com/MetaMask/ocap-kernel/pull/952))
+- Add `replaceNodeEnvPlugin` to the `./vite-plugins` exports, a Rolldown transform plugin that inlines `process.env.NODE_ENV` as the literal `"production"` in any module referencing it — used by `bundleVat` in place of a build-config `define`, so vats that pull in libraries like immer resolve the reference at bundle time ([#967](https://github.com/MetaMask/ocap-kernel/pull/967))
