boto 2.38.0

Released: 9-Apr-2015

Boto 3

Boto3, the next version of Boto, is now stable and recommended for general use. It can be used side-by-side with Boto in the same project, so it is easy to start using Boto3 in your existing projects as well as new projects. Going forward, API updates and all new feature work will be focused on Boto3.

To assist users who still depend on Boto and cannot immediately switch over, we will be triaging and addressing critical issues and PRs in Boto in the short term. As more users make the switch to Boto3, we expect to reduce our maintenance involvement over time. If we decide on a cutoff date or any significant changes to our maintenance plan, we will make pre-announcements well ahead of schedule to allow ample time for our users to adapt/migrate.


Boto is a Python package that provides interfaces to Amazon Web Services. Currently, all features work with Python 2.6 and 2.7. Work is under way to support Python 3.3+ in the same codebase. Modules are being ported one at a time with the help of the open source community, so please check below for compatibility with Python 3.3+.

To port a module to Python 3.3+, please view our Contributing Guidelines and the Porting Guide. If you would like, you can open an issue to let others know about your work in progress. Tests must pass on Python 2.6, 2.7, 3.3, and 3.4 for pull requests to be accepted.

The goal of boto is to support the full breadth and depth of Amazon Web Services. In addition, boto provides support for other public services such as Google Storage in addition to private cloud systems like Eucalyptus, OpenStack and Open Nebula.

Boto is developed mainly using Python 2.6.6 and Python 2.7.3 on Mac OSX and Ubuntu Maverick. It is known to work on other Linux distributions and on Windows. Most of Boto requires no additional libraries or packages other than those that are distributed with Python. Efforts are made to keep boto compatible with Python 2.5.x but no guarantees are made.
