SDK version 1.2.1 released

We've released version 1.2.1 of the SDK for the Python runtime. Here are some highlights from the release notes:

  • Stable, unique IDs for User objects. The Users service now provides a unique user_id for each user that stays the same even if a user changes her email address.
  • The Images API now supports compositing images and calculating a color histogram for an image.
  • New allowed mail attachment types: ics, vcf
  • Urlfetch requests can now set the User-Agent header.
  • An App Engine-specific version of the Python PyCrypto cryptography library is now available. Learn more at
  • The bulk loader configuration format has changed to allow non-CSV input. This change is not backwards compatible, so if you've written code for the bulk loader, it will need to be updated.
  • An early release of the bulk downloader is also now available in Learn more about these changes at:
