boto v2.9.3
===========

:date: 2013/05/15

This release adds ELB support to Opsworks, optimized EBS support in EC2
AutoScale, Parallel Scan support to DynamoDB v2, a higher-level interface to
DynamoDB v2 and API updates to DataPipeline.


Features
--------

* ELB support in Opsworks - You can now attach & describe the Elastic Load
  Balancers within the Opsworks client. (:sha:`ecda87`)
* Optimized EBS support in EC2 AutoScale - You can now specify whether an
  AutoScale instance should be optimized for EBS I/O. (:sha:`f8acaa`)
* Parallel Scan support in DynamoDB v2 - If you have extra read capacity &
  a large amount of data, you can scan over the records in parallel by
  telling DynamoDB to split the table into segments, then spinning up
  threads/processes to each run over their own segment. (:sha:`db7f7b` & :sha:`7ed73c`)
* Higher-level interface to DynamoDB v2 - A more convenient API for using
  DynamoDB v2. The :ref:`DynamoDB v2 Tutorial <dynamodb2_tut>` has more
  information on how to use the new API. (:sha:`0f7c8b`)


Backward-Incompatible Changes
-----------------------------

* API Update for DataPipeline - The ``error_code`` (integer) argument to
  ``set_task_status`` changed to ``error_id`` (string). Many documentation
  updates were also added. (:sha:`a78572`)
