Why Right Now Is the Best Time To Switch From Ignition 8.1 to 8.3

If you're still running Ignition 8.1, you're in good company. It's a rock-solid release that has served the Ignition community well. But while you’ve been enjoying 8.1, Ignition 8.3 has become something extraordinary.

The Ignition 8.3 major-version release occurred last September, bringing many powerful updates to the platform. More recently, the minor-version releases of Ignition 8.3.5 and Ignition 8.3.6* have delivered some of the most significant performance improvements in the platform's history, and are a significant leap forward for customers running large enterprise systems and Cirrus Link MQTT modules, making a compelling case that now is the best time to make the switch. (*Shortly after its release, Ignition 8.3.5 was taken down due to a notable regression and quickly replaced with Ignition 8.3.6.)

8.3 Is a New Era for Ignition

When we launched 8.3, it was much more than a standard version bump. It was a fundamental rethinking of what Ignition could be: a more open, scalable, secure, and capable platform that helps you adapt to a world where AI-integrated operations and virtualized infrastructures are becoming more common.

Here's a quick look at the groundbreaking updates and features introduced in Ignition 8.3.

A Brand-New Historian Solution

Ignition 8.3 comes with a completely redesigned historian system, including the QuestDB-powered Core Historian that requires zero database configuration, and stores and queries data up to 10 times faster than Ignition's previous internal tag history provider. Also, the new SQL Historian Module handles large-scale storage needs with automatic compression, partitioning, and aggregation.

The Event Streams Module

This new Ignition module lets you map, filter, and route data from tags, databases, REST APIs, IIoT services, and more through a single drag-and-drop interface without heavy coding. It also makes building complex event-driven architectures far simpler and allows you to react to tag changes, publish data to event brokers and message queues, and centralize event management across your entire operation in one place.

A Reimagined Perspective

Ignition 8.3 brings a state-of-the-art Drawing Editor for building vector graphics in the Designer, a dynamic Form Builder that replaces the old component-stitching approach, and a new Offline Mode that lets operators input data without an internet connection and syncs automatically on reconnect.

Secrets Management

Ignition 8.3 added a dedicated system for storing sensitive credentials securely, removing passwords, certificates, and encryption keys from Gateway configuration entirely. With secrets management, sensitive information is stored and protected from unauthorized parties in one central location, giving enterprise teams far greater control over their security posture. 8.3 also enables you to use third-party secrets management platforms like HashiCorp Vault with various cloud services on the horizon.

Built for Modern Deployment

Containerization is a major focus in Ignition 8.3, with better Kubernetes support via the new Ignition Helm Chart, Deployment Modes for managing development, staging, and production environments in a single server, and file-based storage that makes version control with Git a native part of the workflow.

Alarm Metrics Aggregation

Ignition 8.3 enables you to get alarm metrics aggregation at the folder and UDT level, turning what was once a complicated workaround into a simple binding. Alarm metrics are now subscription-based rather than polling-dependent, making them faster and more accurate to retrieve. This update also made more than a dozen other pre-existing properties bindable.

If you're building high-performance HMIs or dashboards that need to meet ISA 18.2 Alarm Management Standards, this feature is a game-changer.

LTS

Also, as an LTS release, you can count on 8.3 for the long haul, just like you've counted on 8.1.

This is just scratching the surface of what Ignition 8.3 introduced, but as impressive as the initial release was, 8.3 has continued to improve far beyond these updates and features.

Why Ignition 8.3.6 Is More Than a Minor Update

Minor version updates don't always get much fanfare, but Ignition 8.3.6 is a different story. This release delivers profound performance improvements, and it represents a significant leap forward for customers running large enterprise systems, and here’s why.

4X Throughput for Managed Tag Providers

The headlining improvement in Ignition 8.3.6 is a major overhaul of the Gateway's configuration file system. It provides four times greater throughput for managed tag providers by allowing operations on different resource types to proceed concurrently with minimal locking.

Ignition 8.3.6’s tag value handling is faster, the Gateway configuration system is more responsive, and it vastly improves the process of writing Ignition resources, including EAM agents, OPC-UA server profiles, database connections, and more. Also, new Gateway diagnostic resource metrics let you monitor those resources more closely through the Metrics Dashboard.

Security Gets Another Layer

Building on Ignition 8.3's Secrets Management foundation, Ignition 8.3.6 adds a new "File" Secret Provider type that lets you read secrets from files on disk rather than storing them internally in the Gateway. This adds another layer of control over where and how you store your sensitive credentials.

Ignition 8.3.6 also introduces Global Discovery Server (GDS) support for OPC UA, giving you the ability to automate certificate management for multiple OPC UA servers and devices from a single central location. For enterprise environments managing many OPC UA connections across a dispersed system, this is a major step forward.

Developer Flexibility for Complex Tag Systems

Ignition 8.3.6 adds the overridesOnly parameter to the system.tag.getConfiguration() function, which is another massive improvement for organizations using enterprise architectures with large, complex tag systems.

When set to True, it returns only the local overridden properties from UDT members, cutting through the noise for developers working with complex tag hierarchies and heavy override usage.

The Upgrade Is Easier Than You Think
