Eclipse VOLTTRON 11 Release Candidate

The Eclipse VOLTTRON 11 Release Candidate is a major refactor of modular VOLTTRON to make message bus, authentication and authorization features pluggable/customizable. Because of the nature of this refactor, this version is backward incompatible with previous versions of VOLTTRON. This release is compatible with python 3.10. We will shortly be making a new release to move development to 3.11 and 3.12.

New Features and improvements

1. In this version of modular VOLTTRON, we have refactored VOLTTRON 10.0.5rc4 into three logical code bases - volttron-core, volttron-lib-auth, and volttron-lib-zmq. This enables users to easily customize/replace the message bus and authentication/authorization implementation used with VOLTTRON. 
2. Redesign of authentication and authorization:
   • Authentication and Authorization are separated into distinct components with customizable persistence layer
   • Redesigned authorization for both RPC exported methods and message bus topics.
   • Authorization rules can now be applied to individual instance of agents
   • Authorization rules are no longer a part of source code of an agent
   • Authorization rules are defined for specific >vipid<.>methodname< instead of definition based on arbitrary capability strings
   • Pubsub topics can now be both read and write protected
   • New vctl authz command to add and remove authorization entries
3. Driver Redesign
   • Optimized tree-based data model allowing for
     • Storage of last known values.
     • Metadata about points and devices.
   • Improved Poll Scheduling, which:
     • Allows point-level trending.
     • Permits configuration of un-polled points.
     • Automatically spreads polls evenly throughout the available period.
     • Improves polling efficiency by avoiding duplicate requests to shared remote devices.
   • Validation of all configuration parameters and automatic type correction.
   • Enhanced API with query based on pattern matching.

Installable Agents and Libraries

VOLTTRON is now split into multiple repositories. Each repository contains the code for individual agents or a library needed for one of the agents to do its job.
