# Panfactum Changelog — edge.24-08-12

> Moves repository variables to panfactum.yaml for improved CI/CD integration, introduces Workflow Engine and Event Bus addons, and upgrades Argo-related modules to Beta status.

## Highlights

- Repository variables moved from `devenv.nix` to `panfactum.yaml` at repo root — breaking change
- New [Workflow Engine addon](https://panfactum.com/docs/edge/guides/addons/workflow-engine/installing) (Argo Workflows) and [Event Bus addon](https://panfactum.com/docs/edge/guides/addons/event-bus/installing) (Argo Events)
- Multiple Argo-related modules graduated to Beta status

## Breaking Changes

- [Repository variables](https://panfactum.com/docs/edge/reference/configuration/repo-variables) must now be defined in a `panfactum.yaml` file at the root of your repository instead of in `devenv.nix`.
  - Impacts: configuration `panfactum.yaml` — Repository variables migrated from devenv.nix to panfactum.yaml

## Additions

- New addons: a [Workflow Engine](https://panfactum.com/docs/edge/guides/addons/workflow-engine/installing) (Argo Workflows) and an [Event Bus](https://panfactum.com/docs/edge/guides/addons/event-bus/installing) (Argo Events).
  - Impacts: iac-module `kube_argo` — New Workflow Engine addon added
  - Impacts: iac-module `kube_argo_event_bus` — New Event Bus addon added
- New [guide and best practices](https://panfactum.com/docs/edge/guides/cicd/getting-started) for setting up CI/CD in the Panfactum Stack.
- The following infrastructure modules upgraded to Beta status: `kube_argo`, `kube_argo_event_bus`, `kube_argo_event_source`, `kube_argo_sensor`, `wf_spec`, `wf_tf_deploy`, `wf_dockerfile_build`.
  - Impacts: iac-module `kube_argo` — Upgraded to Beta status
  - Impacts: iac-module `kube_argo_event_bus` — Upgraded to Beta status
  - Impacts: iac-module `kube_argo_event_source` — Upgraded to Beta status
  - Impacts: iac-module `kube_argo_sensor` — Upgraded to Beta status
  - Impacts: iac-module `wf_spec` — Upgraded to Beta status
  - Impacts: iac-module `wf_tf_deploy` — Upgraded to Beta status
  - Impacts: iac-module `wf_dockerfile_build` — Upgraded to Beta status
- Adds `pf-get-repo-variables` which prints a JSON payload of all repository configuration variables with defaults.
  - Impacts: devshell `pf` — New pf-get-repo-variables command added

## Upgrade Instructions

## Migrate Repository Variables to `panfactum.yaml`

[Repository variables](https://panfactum.com/docs/edge/reference/configuration/repo-variables) must now be defined in a `panfactum.yaml` file
at the root of your repository instead of in your `devenv.nix`.

Variable names are no longer prefixed with `PF_` and are now lowercase.

**Example migration:**

Before (in `devenv.nix`):

```nix
env.PF_REPO_NAME = "my-repo";
env.PF_REPO_URL = "https://github.com/my-org/my-repo";
```

After (in `panfactum.yaml` at repo root):

```yaml
repo_name: my-repo
repo_url: https://github.com/my-org/my-repo
```

This change makes it easier to reference these values outside of local development contexts such as CI pipelines where
`devenv.nix` isn't loaded.
