EdgeX Foundry, the open source, vendor-neutral edge computing framework under the LF Edge umbrella, announced the release of EdgeX 4.0, code named “Odesa.” This latest major update is designed to strengthen industrial edge deployments with enhanced security, scalability, and open-source integrity. As a Long-Term Supported (LTS) release, this version offers the advantage of community-based support.
New Features for Industrial-Grade Deployments
Guided by real-world industrial requirements and its Technical Steering Committee (TSC)—featuring experts from Schneider Electric, Eaton, Danfoss, and Intel—EdgeX 4.0 introduces the following new capabilities:
PostgreSQL as the default database to enhance reliability, backup, and recovery for critical edge operations.
Time-based scheduling that allows precise, time-driven execution of edge processes, replacing the earlier interval-based method.
End-to-End authentication which implements Zero-Trust Networking principles for a more secure industrial edge.
The new Python API expands accessibility for developers, unlocking new AI and automation use cases at the edge.
Open Source
EdgeX Foundry remains committed to a fully open and vendor-neutral framework. In this release, key third-party components that moved away from Apache 2.0-compatible licensing have been replaced, ensuring full transparency:
PostgreSQL: Now the framework’s primary internal database.
OpenBao: A Linux Foundation-hosted project for edge secret storage.
Core Keeper: A dedicated new open-source configuration and registry service.
MQTT: Now the default internal message bus, optimizing data flow between EdgeX services.
