The VOLTTRON(tm) 1.0 release includes the following features:

• Scheduler 2.0: The new ActuatorAgent scheduler allows applications to reserve devices ahead of time
• SchedulerExample: This simple agent provides an example of publishing a schedule request.

VOLTTRON v1.0 also includes features in a beta stage. These features are slated for release in v1.1 but are included in 1.0 for those who wish to begin investigating them. These features are:

• Multi-node communication: Enables platforms to publish and subscribe to each other
• BACNet Driver: Enables reading/writing to devices using the BACNet protocol

Included are PNNL developed applications: AFDD and DR which are in the process of being modified to work with the new scheduler.DR will not currently function with Scheduler 2.0.

The agent module was split into multiple pieces.

• The BaseAgent and PublishMixin classes and the periodic decorator remain in the agent package.
• The matching module was moved under the agent package and is now available as volttron.lite.agent.matching.
• The utility functions, like run_agent (which is deprecated) and the base agent ArgumentParser, were moved to volttron.lite.agent.utils.

All low-level messaging that is not agent-specific was moved to volttron.lite.messaging and includes the following new submodules:

• headers: contains common messaging headers, like CONTENT_TYPE, and values as constants
• topics: provides topic templates; see the module documentation for details
• utils: includes the Topic class and other messaging/topic utilities

The listener, control, archiver, and actuator agents were updated to use and demonstrate the changes above. Some of them also show how to use agent factories to perform dynamic matching. Using mercurial to show the diffs between revisions is a good technique for others to use to investigate how to migrate their agents.

Version 1.0

This is the initial release of the Volttron Lite platform. The features contained in it are:

• Scripts for building the platform from scratch as well as updating
• A BaseAgent which expresses the basic functionality for an agent in the platform as well as hooks for adding functionality
• Example agents which utilize the BaseAgent to illustrate more complex behavior

In addition, this wiki will be constantly updated with documentation for working with the platform and developing agents in it. We intend to document as much as possible but please submit TRAC tickets in cases where documentation does not exist yet or there is difficulty locating it. Also, this is a living document so feel free to add your own content to this wiki and even make changes to the documentation if you can improve on its clarity and usefulness.
