# Migrations

Some versions need some changes to the server configuration or the pipeline configuration files.

## 0.15.0

- Default value for custom pipeline path is now empty / un-set which results in following resolution:

  `.woodpecker/*.yml` -> `.woodpecker.yml` -> `.drone.yml`

  Only projects created after updating will have an empty value by default. Existing projects will stick to the current pipeline path which is `.drone.yml` in most cases.

  Read more about it at the [Project Settings](/docs/usage/project-settings#pipeline-path)

- Dropped support for `DRONE_*` environment variables. The according `WOODPECKER_*` variables must be used instead.
  Additionally some alternative namings have been removed to simplify maintenance:
  - `WOODPECKER_AGENT_SECRET` replaces `WOODPECKER_SECRET`, `DRONE_SECRET`, `WOODPECKER_PASSWORD`, `DRONE_PASSWORD` and `DRONE_AGENT_SECRET`.
  - `WOODPECKER_HOST` replaces `DRONE_HOST` and `DRONE_SERVER_HOST`.
  - `WOODPECKER_DATABASE_DRIVER` replaces `DRONE_DATABASE_DRIVER` and `DATABASE_DRIVER`.
  - `WOODPECKER_DATABASE_DATASOURCE` replaces `DRONE_DATABASE_DATASOURCE` and `DATABASE_CONFIG`.

- From version `0.15.0` ongoing there will be three types of docker images: `latest`, `next` and `x.x.x` with an alpine variant for each type like `latest-alpine`.
  If you used `latest` before to try pre-release features you should switch to `next` after this release.

- Prometheus metrics have been changed from `drone_*` to `woodpecker_*`

- Base path has moved from `/var/lib/drone` to `/var/lib/woodpecker`

- Default SQLite database location has changed:
  - `/var/lib/drone/drone.sqlite` -> `/var/lib/woodpecker/woodpecker.sqlite`
  - `drone.sqlite` -> `woodpecker.sqlite`

- ...
