Fluxnova 3.0: what shipped, what breaks, and what to do.
The largest release since the FINOS fork went GA in July 2026. It modernises the platform substantially and it puts a major version migration in front of every existing user.
What shipped
Platform modernisation
Spring Boot 4 and fourteen further library upgrades that had reached end of life.
Control Center UI
Process definitions, heat maps, instance migration, incident replay, history, and DMN rule management with audit visibility into rule execution.
Adhoc subprocesses
Dynamic case management, where the steps are not declared in the model in advance.
Restricted variables
PII protection inside a process model.
Plugin ecosystem
Custom engine behaviour including history data and authentication and authorization.
MCP and agentic subprocesses
Processes exposed as tools invocable by LLMs and agents, and agents executing workflow tasks dynamically from prompts and business context.
What breaks
Cockpit is being retired
The legacy UI is on the roadmap for removal. Control Center replaces it.
JBoss and WildFly
End of support. If you deploy on either, you have a forced move.
Library surface
Fifteen upgrades including Spring Boot 4. Anything you have built against the old surface needs testing.
Agentic adhoc subprocesses removed the control point.
BPMN’s audit trail is trustworthy because every step is knowable in advance. A service task calls a system. A user task calls a person. The history is complete evidence precisely because nothing in it was improvised.
An agentic adhoc subprocess declares nothing in advance and determines its steps at runtime. The engine records that it ran. It has no opinion on whether the agent was inside its authority, and there is no human task left where accountability used to attach.
Common questions
- When was Fluxnova 3.0 released?
- July 2026, announced GA by the FINOS maintainers.
- Do I have to upgrade?
- Not immediately, but the direction is set. Cockpit is being retired and JBoss and WildFly support is ending, so anyone on those app servers has a forced move rather than a choice.
- Is Fluxnova abandoned?
- No. Version 3.0 is the largest release since the fork and the maintainers are active. The gap for a regulated institution is not code maintenance. It is having an accountable operator.
- What is an agentic adhoc subprocess?
- A subprocess whose steps are not declared in the process model and are instead determined at runtime by an AI agent, from prompts and business context.
