We're excited to announce the release candidate for Pytanis v0.9.0! This is the first version fully compatible with the new Pretalx versioned API v1, introduced in June 2025.

  • Seamless backward compatibility for existing code

2. Storage & Communication Abstraction

pip install pytanis[helpdesk]   # For HelpDesk

3. Performance Improvements

Migration Guide

For Existing Users

Your code will continue to work without changes. To take advantage of new features:

  1. Update to use optional dependencies: 

    # Instead of installing everything
pip install pytanis

# Install only what you need
pip install pytanis[google,mailgun]

  2. Use the new abstraction layer (optional): 

    # Old way (still works)
from pytanis import GSheetsClient
client = GSheetsClient()

# New way (recommended)
from pytanis import get_storage_client
storage = get_storage_client()

For New Users

Start with the minimal installation and add components as needed: 

pip install pytanis  # Core functionality
pip install pytanis[all]  # Everything

Bug Fixes

  • Fixed 401 Unauthorized errors when fetching individual answers
  • Fixed redirect issues with missing trailing slashes
  • Fixed circular import issues in Google storage adapter
