Upgrade Guide

Important

If upgrading from 0.x or 1.x, you must run the following migration to transform existing datasource credentials. This step is required to ensure compatibility with the new version:

uv run flask transform-datasource-credentials

Docker Compose Deployments

1. Back up your customized docker-compose YAML file (optional)

cd docker
cp docker-compose.yaml docker-compose.yaml.$(date +%s).bak

2. Get the latest code from the main branch

git checkout 2.0.0-beta.2
git pull origin 2.0.0-beta.2

3. Stop the service. Please execute in the docker directory

docker compose down

4. Back up data

tar -cvf volumes-$(date +%s).tgz volumes

5. Upgrade services

docker compose up -d

6. Migrate data after the container starts

docker exec -it docker-api-1 uv run flask transform-datasource-credentials

Source Code Deployments

1. Stop the API server, Worker, and Web frontend Server.

2. Get the latest code from the release branch:

git checkout 2.0.0-beta.2

3. Update Python dependencies:

cd api
uv sync

4. Then, let's run the migration script:

uv run flask db upgrade
uv run flask transform-datasource-credentials

5. Finally, run the API server, Worker, and Web frontend Server again.

[RoyCoya]

is the branch in Upgrade Guide wrong?
2.0.0-beta.1 shall be 2.0.0-beta.2

[laipz8200]

We also need to update the plugin container version.
The new version is "langgenius/dify-plugin-daemon:0.3.1-local".(2025/10/9)

Hi,
I’d like to ask whether the Flexible Execution Start Points feature is available in 2.0.0-beta2.
I upgraded from 1.8.1, but I wasn’t able to find how to access or use this functionality.
If it’s already supported, could you point me to the right way to try it out?
Thanks so much!

[laipz8200]

This is a feature of our new workflow engine, but not built with any functions for now.
