What's New in Dify 2026

Major features and improvements shipped in 2026. For the full release notes, see the official GitHub releases.

MCP (Model Context Protocol) Support

New in 2026

Dify now supports MCP as a client, letting your agents connect to any MCP server — filesystems, GitHub, Slack, databases, web browsers. Add MCP tools in Settings → Tool Providers → MCP.

# Example: Add filesystem MCP server
npx @modelcontextprotocol/server-filesystem /allowed/path

Multi-Agent Orchestration

Major Update

Improved Agent loop with better tool-call retry logic, parallel tool execution, and a new Supervisor agent mode that coordinates multiple sub-agents for complex multi-step tasks.

Enhanced RAG Pipelines

Improved

Hybrid search (dense + sparse vector), improved chunk reranking, parent-document retrieval, and support for larger documents. New Q&A extraction mode for building FAQ knowledge bases automatically.

New LLM Provider Support

Expanded

Added native support for Gemini 2.0 Flash/Pro, Claude 3.5 Sonnet/Haiku, GPT-4o mini, DeepSeek V3/R1, Mistral Large, and local models via Ollama and LM Studio. Over 100+ model configurations supported.

Built-in Evaluation Framework

New

Test your AI apps directly in Dify using annotated datasets. Run bulk evaluations against golden datasets, track accuracy over time, and compare model outputs side by side — no external tooling needed.

How to Update Self-Hosted Dify

Update to the latest version in under 2 minutes. All your data, apps, and API keys are preserved.

1

Back up your database (recommended)

# Backup Postgres data
docker exec dify-db pg_dump -U postgres dify > dify_backup_$(date +%Y%m%d).sql
2

Pull the latest code

# Navigate to your Dify directory
cd /opt/dify/docker
# Pull latest changes from GitHub
git pull origin main
3

Pull new Docker images

docker compose pull
4

Restart containers

docker compose up -d
# Verify all containers are running
docker compose ps
✓

Done — visit your Dify dashboard

Database migrations run automatically on startup. Open your Dify URL and verify the version in Settings → About.

Complete update in one command (when already in the docker directory):

git pull origin main && docker compose pull && docker compose up -d

Common Update Issues & Fixes

Container won't start after update

Usually a migration issue. Check logs and wait 30 seconds — the api container runs migrations on startup.

docker compose logs api --tail=50

Old containers still running after pull

Force recreate all containers to ensure new images are used:

docker compose up -d --force-recreate

Disk full after updates

Old Docker images accumulate. Clean them up:

docker image prune -f
