<details>
<summary>av1155/houndarr (av1155/houndarr)</summary>

### [`v1.5.0`](https://github.com/av1155/houndarr/releases/tag/v1.5.0)

[Compare Source](https://github.com/av1155/houndarr/compare/v1.4.0...v1.5.0)

##### Added

- Non-root container startup is now supported via pod `securityContext` for clusters enforcing Pod Security Standards, as an alternative to the default `PUID`/`PGID` remapping mode ([#&#8203;258](https://github.com/av1155/houndarr/issues/258)).
- Proxy authentication mode (`HOUNDARR_AUTH_MODE=proxy`) delegates login to an upstream identity-aware proxy via a configurable request header ([#&#8203;259](https://github.com/av1155/houndarr/issues/259)).
- Official Helm chart published to `oci://ghcr.io/av1155/charts/houndarr`; Flux users can deploy with an `OCIRepository` + `HelmRelease` instead of raw manifests ([#&#8203;261](https://github.com/av1155/houndarr/issues/261)).
