To top January up, boto 2.2.0 has been released, bringing in, amongstother things, DynamoDB support. See the full release notes for the nitty-gritty. Feedback is actively being sought for the DynamoDB module, so please do open an issue on the tracker if you run into issues or have suggestions.
Also, we’re making a ton of progress on the documentation front. If you’d like to help, check out the documentation issues in the tracker, and/or hop in #boto in FreeNode. We’re in need of people familiar with various boto sub-modules to step up and contribute their knowledge, or give their respective module’s tutorials/api references some love.
