Added test support for RabbitMQ installations of all core agents.
Added multiplatform (zmq and rmq based platform) testing.
Integrated RabbitMQ documentation into the core documentation.
Update libraries to appropriate and compatible versions
String handling efficiency
Encode/Decode of strings has been simplified and centralized
Added additional test cases for frame serialization in ZMQ
Syntax updates such difference in handling exceptions, dictionaries, sorting lists, pytest markers etc.
Made bootstrap process simpler
Resolved gevent monkey patch issues when using third party libraries
RabbitMQ Message Bus¶
- Client code for integrating non-VOLTTRON applications with the message bus
available at: https://github.com/VOLTTRON/external-clients-for-rabbitmq
Includes support for MQTT, non-VOLTTRON Python, and Java-based RabbitMQ clients
Config store secured¶
Agents can prevent other agents from modifying their configuration store entry
Known Issues which will be dealt with for the final release:¶
Python 3.7 has conflicts with some libraries such as gevent
The VOLTTRON Central agent is not fully integrated into Python3
CFFI library has conflicts on the Raspian OS which interferes with bootstrapping
VOLTTRON 7.0 Full Release¶
This is a full release of the 7.0 version of VOLTTRON which has been refactored to work with Python3. This release incorporates community feedback from the release candidate as well as new contributions and features. Major new features and highlights since the release candidate include:
Added secure agent user feature which allows agents to be launched as a user separate from the platform. This protects the platform against malformed or malicious agents accessing platform level files
Added a driver to interface with the Ecobee smart thermostat and make data available to agents on the platform
Updated VOLTTRON Central UI to work with Python3
Added web support to authenticate remote VOLTTRON ZMQ message bus-based connections
Updated ZMQ-based multiplatform RPC with Python 3
To reduce installation size and complexity, fewer services are installed by default
MasterDriver dependencies are not installed by default during bootstrap. To use MasterDriver, please use the following command:
python3 bootstrap.py --driver
Web dependencies are not installed by default during bootstrap. To use the MasterWeb service, please use the following command:
python3 bootstrap.py --web
Added initial version of test cases for volttron-cfg (vcfg) utility
On all arm-based systems, libffi is now a required dependency, this is reflected in the installation instructions
On arm-based systems, Raspbian >= 10 or Ubuntu >= 18.04 is required
Updated examples and several contributed features to Python 3
Inclusion of docker in test handling for databases
A new /gs endpoint to access platform services without using Volttron Central through Json-RPC
A new SCPAgent to transfer files between two remote systems
Continued documentation updates to ensure correctness
Rainforest Eagle driver is not yet upgraded to Python3
A bug in the Modbus TK library prevents creating connections from 2 different masters to a single slave.
BACnet Proxy Agent and BACnet auto configuration scripts require the version of BACPypes installed in the virtual environment of VOLTTRON to be version 0.16.7. We have pinned it to version 0.16.7 since it does not work properly in later versions of BACPypes.
VOLTTRON 7.0 code base is not fully tested in Ubuntu 20.04 LTS so issues with this combination have not been addressed
