 | Name | Type | Description |
 | ---- | ---- | ----------- |
-| Multiple `Warehouse`s | feature | Improve UI support for multiple Freightlines rooted in different `Warehouse`s. |
-| Manual `Freight` Creation | feature | Add CLI and UI support for manual `Freight` creation. This will give users the flexibility to create novel combinations of artifacts that `Warehouse`s will not -- for instance, pairing the most recent version of a container image with an _older_ version of application manifests. |
-| ECR/GitHub Auth | feature | Native authentication support for ECR registries and using GitHub applications | 
-| [Patch Promotions](https://github.com/akuity/kargo/issues/1250) | poc | Support a generalized option to promote arbitrary configuration (e.g. strings, files, and directories) to other paths of a GitOps repository. |

+| Auth via [GitHub Apps](https://docs.github.com/en/apps) | feature | Support GitHub Apps as an authentication option for GitHub and ghcr.io repositories. |
+| Multiple `Freight` per `Stage` | feature | The overarching theme of the release: Permit `Stage`s to host multiple pieces of `Freight` from different `Warehouse`s. This will permit different artifacts, or sets of artifacts, to be promoted through a pipeline with different/independent cadence. |
