v4.0.0

🚨 Breaking changes

Helm chart / deployment config

• Secret schema refactor (values + templates): secrets for basic auth, Langfuse, S3, STACKIT, and RAGAS are now split into individual fields (e.g., username/password or API key) and can be sourced via secretKeyRef in values.yaml. Helm templates were updated accordingly (including ingress/basic-auth handling). You’ll need to adapt existing values.yaml + secrets to the new structure. ([GitHub]1)
• New secret-resolution helpers: templates now prefer secretKeyRef.name when provided and otherwise fall back to default names. This can change which secret names your deployments expect. ([GitHub]1)
• New local Langfuse init workflow: local dev can generate a stable Langfuse init secret from a .env.langfuse via Kustomize/Tilt; docs and Tiltfile were updated. ([GitHub]1)

Frontend service configuration

• Frontend auth env vars removed: VITE_AUTH_USERNAME / VITE_AUTH_PASSWORD were removed from .env.template. The frontend auth prompt now reuses BASIC_AUTH_USER / BASIC_AUTH_PASSWORD. If your frontend deployment relied on VITE_AUTH_*, you must migrate. ([GitHub]2)

Local dev / build workflow

• Dockerfiles split into prod and dev variants: services now use Dockerfile (prod) and Dockerfile.dev (dev). Tilt supports switching to dev Dockerfiles for live iteration—any custom build references may need updating. ([GitHub]3)

---

✨ Added

• Sitemap uploads: “continue on failure” option end-to-end:

  • Backend parses and normalizes continue_on_failure and defaults it to True if not provided (more resilient crawling by default).
  • Admin frontend adds a checkbox (default checked) and passes the value through the API payload. ([GitHub]4)

---

🔧 Changed

Release automation (GitHub Actions)

• Release pipeline split into modular workflows (instead of one monolith): prepare-release, create-release, publish libs, build images, publish chart, etc., with label-gating (prepare-release, refresh-locks, chart-bump) to control progression and avoid unnecessary CI runs. ([GitHub]5)
• Docker images built on published releases for all services including frontend and admin-frontend, and image digests are collected as artifacts. ([GitHub]5)
• Release creation behavior: create-release.yml creates a Git tag + GitHub release when a PR with the refresh-locks label is merged (version is extracted from PR title). ([GitHub]5)
• Manual chart version bump workflow added (bump-chart-version.yml). ([GitHub]5)

Frontend

• Major dependency updates were applied to the frontends (repo-wide refresh). ([GitHub]6)

---

🧭 Migration notes

If you deploy the frontend

• Replace any usage of:

  • VITE_AUTH_USERNAME → BASIC_AUTH_USER
  • VITE_AUTH_PASSWORD → BASIC_AUTH_PASSWORD ([GitHub]2)

If you deploy via Helm

• Review and update your values.yaml and referenced Kubernetes secrets to match the new secret field structure and (optionally) use secretKeyRef for integration with external secret managers. ([GitHub]1)

If you run locally via Tilt

• If you had custom Docker build configuration, ensure you’re pointing dev workflows at Dockerfile.dev where appropriate. ([GitHub]3)
