 ## Unreleased
 
-- Added an `outbound-http-proxy` example, which routes outbound traffic from frontend and worker through an HTTP proxy with `HTTP_PROXY`, `HTTPS_PROXY`, and `NO_PROXY`
+- Added an `outbound-http-proxy` example, which routes outbound traffic from frontend, worker, and migrator through an HTTP proxy with `HTTP_PROXY`, `HTTPS_PROXY`, and `NO_PROXY`
 - Fixed the `codeintel-db` PersistentVolumeClaim being renamed by `codeIntelDB.name`, which left the StatefulSet pointing at a `codeintel-db` claim that no longer existed and stuck the pod in `Pending`. The PVC is now always named `codeintel-db`, matching the other components and the documented behaviour of `*.name`. If you worked around this by creating a `codeintel-db` PVC by hand, label it `app.kubernetes.io/managed-by: Helm` and annotate it with `meta.helm.sh/release-name` and `meta.helm.sh/release-namespace` before upgrading so Helm can adopt it. [#612](https://github.com/sourcegraph/deploy-sourcegraph-helm/issues/612)
 - Added opt-in Redis config management through `redisCache.config.enabled` and `redisStore.config.enabled` (both default to `false`). Default deployments retain their image configs, custom mounts, authentication, and memory settings. When enabled, the chart mounts `/etc/redis/redis.conf` and supports `existingConfig`, `maxmemory`, `maxmemoryRatio`, `maxmemoryPolicy`, and `additionalConfig`. See [Enabling Redis config management](README.md#enabling-redis-config-management) before opting in, especially when using custom images or Secret-mounted configs.
 - With Redis config management enabled, the chart sizes `maxmemory` at 75% of `resources.limits.memory` to leave room for overhead; this reduces, but does not eliminate, OOM risk. Ratios must be greater than 0 and less than 1. Auto-sizing is skipped in local development mode or when the limit is absent or unrecognised. At the default 7Gi limit, opting in lowers the effective cap from 6GiB to 5.25GiB: `redis-cache` evicts earlier, but `redis-store` uses `noeviction`, so its write-error ceiling drops too. Set `redisStore.config.maxmemory: 6gb` to keep the old ceiling if the pod has sufficient memory.
