# Upgrading to DefectDojo Version 1.13.x

- See release notes: [https://github.com/DefectDojo/django-DefectDojo/releases/tag/1.13.0](https://github.com/DefectDojo/django-DefectDojo/releases/tag/1.13.0)

- Hashcode settings affecting deduplication have changed, to update existing findings run:

```bash
./manage.py dedupe
```

If you’re using docker:

```
docker-compose exec uwsgi ./manage.py dedupe
```

This can take a while depending on your instance size. It might be possible that new duplicates are detected among existing findings, so make a backup before running!
