EMERGENCY FIX: ADD FEATURE dialog of Agent application that incorrectly used the Text Generator App dialog content.

Introducing Dify Workflow! 🎉

The much-anticipated workflow feature is here: In a nutshell, workflow provides a visual canvas for defining complex tasks as smaller, manageable steps (nodes). This reduces reliance on prompt engineering and LLM agent capabilities, taking the stability and reproducibility of your LLM applications to the next level by letting you be in control.

There are two Workflow application types with this update:

  • Workflow App
    Targeting Automation and Batch Processing: This is ideal for translation, data analysis, content generation, email automation, and more.
    image

  • Chatflow App (A Sub-Type of Chatbot)
    For Conversational Applications: Suitable for customer service, semantic search, and more conversational apps requiring multi-step logic in crafting the response.
    Compared to the regular Workflow app type, Chatflow adds chat-specific features such as conversation history support (Memory), tagged replies, an Answer node type for streaming responses, and support for rich text and images.

For more information, please visit: https://docs.dify.ai/features/workflow/introduce

Other Enhancements:

  • Optimized UI flow for app creation.

  • Conversion support from various basic application types to Workflow-based applications.

    • Basic / Expert mode Chatbot apps → Chatflow

    • Text Generator → Workflow

      image

  • Dify's official app templates are now available in self-hosted mode.

  • Support for adding descriptions to applications.

  • Support for porting applications in and out of Dify with DSL.

  • Under the hood, we also refactored the underlying execution logic of all app types for cleaner architecture and a tidier repo.

Update Guide

If you need to upgrade from 0.6.0-preview-workflow.1, you will need to connect to PostgreSQL and execute the following SQL (migration inserted in the main branch) to ensure data integrity.

ALTER TABLE dataset_keyword_tables ADD COLUMN data_source_type VARCHAR(255) NOT NULL DEFAULT 'database';
ALTER TABLE embeddings ADD COLUMN provider_name VARCHAR(40) NOT NULL DEFAULT '';
ALTER TABLE embeddings DROP CONSTRAINT embedding_hash_idx;
ALTER TABLE embeddings ADD CONSTRAINT embedding_hash_idx UNIQUE (model_name, hash, provider_name);

Docker compose deployments:

  1. Get the latest code from the main branch:

    git checkout main
git pull origin main

  2. Go to the next step and update to the latest image:

    cd docker
docker compose up -d

  3. We also moved the agent data within the database, Execute the below script to complete the migrate: (NEW)

    docker compose exec api flask convert-to-agent-apps

Source Code deployments:

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

  2. Get the latest code from the main branch:

    git checkout main
git pull origin main

  3. Update Python dependencies:

    cd api
pip install -r requirements.txt

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

    flask db upgrade

  5. We also moved the agent data within the database, Execute the below script to complete the migrate: (NEW)

    flask convert-to-agent-apps

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

Pre-release

Important Notice

This version is a preview release intended for feature workflow internal testing only. It is not a formal release. Please proceed with caution before upgrading. Please do not use it in a production environment.

What's Changed

  • Refactored the variable reference logic for LLM, Answer, Tool, and Http Request nodes. Now you can simply input "/" in the text box to directly select variables without having to declare variable relationships and import them separately.

    Due to changes in the data structure, the previous workflow configurations will no longer be available. Please create a new App to experience it and avoid running into any error issues caused by inconsistent data structures.

    image

  • Optimized the user experience of app creation.

  • A lot of details to optimize for user experience.

  • Fixed few issues.

Vector Database Migrate Tool

When you want to switch to another vector database, you can deactivate or delete the original vector database after switching.

How to use

Step:

  1. If you are starting from local source code, modify the environment variable in the .env file to the vector database you want to migrate to.
    For example:
VECTOR_STORE=qdrant
  1. If you are starting from docker compose, modify the environment variable in the docker-compose.yaml file to the vector database you want to migrate to, both api and worker are all needed.

For example:

# The type of vector store to use. Supported values are `weaviate`, `qdrant`, `milvus`.
VECTOR_STORE: qdrant
  1. run the below command in your terminal or docker container
flask vdb-migrarte

Update Guide

Deploying with Docker Compose:

  1. Get the latest code from the main branch:

    git checkout main
git pull origin main

  2. Go to the next step and update to the latest image:

    cd docker
docker-compose up -d

Deploying from Source Code:

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