See our JIRA for a list of known issues and the section at the end of this post on issues that we are fixing in the near future.
Process Instance Migration
Today’s organizations need to quickly adapt their processes to changing requirements. While they have the tools and skills to rapidly improve BPMN models and supplementary code, immediate control over the state of running process instances is often lacking. The result is a gap between to-be processes and as-is processes.
Camunda BPM 7.5.0 closes that gap by providing the tools to apply improved process models to long-running process instances with minimal interference on process operations. In particular it contains:
- A powerful Java and REST API to migrate process instances
- A comprehensive UI in Camunda Cockpit that puts migration at the fingertips of the end user (Enterprise Edition only)
- Infrastructure to migrate large numbers of process instances
Multi Tenancy with Tenant Identifiers
The new release brings greater flexibility when using Camunda in a multi tenancy scenario. In addition to the existing approach with one process engine per tenant that separates data into different database schemas, you can now employ a single process engine for all tenants. It reduces the effort to manage large tenant bases significantly.
The single engine approach uses tenant identifiers in the form of persistent attributes in the Camunda database schema. Resources can be shared between all tenants or restricted to a single tenant. From a tenant’s perspective, the multi-tenancy concept is transparent. Access is restricted to their own data without interfering with other tenants.
In essence, the new Multi Tenancy feature provides:
- Persistent tenant markers for process engine resources
- Java and REST APIs to set and query by tenant markers
- Camunda Admin UI to manage tenants and tenant membership
- Authentication API for transparent resource access from a tenant’s perspective
- Camunda web application filter for transparent resource access from a tenant’s perspective
- Deployment of shared resources to manage common processes, cases, and decisions for all tenants in one place
Reporting API and Duration Report
Analyze process performance over a period of time with the new reporting features:
- A new history API to programmatically create process instance reports
- A corresponding Cockpit UI (Enterprise Edition only)
Find details on reporting in the alpha1 blog post.
External Task Improvements
The External Task Pattern is a Camunda feature to decouple BPMN flow evaluation in the process engine from task execution.
This release extends the external task concept by two aspects:
- Signal BPMN errors from an external task instance and trigger error-catching events
- Process external tasks by priority
Webapp UI/UX Improvements
The web applications contain the following improvements:
- Cleaner and more consistent web application UI
- Full Keyboard Accessibility for Camunda Tasklist
- New Camunda Cockpit Dashboard
- New Camunda Admin Dashboard
Read the focused blogpost blogpost that introduces the new concepts and compares the 7.4.0 Tasklist design to the new 7.5.0 Tasklist design.
New Supported Environments
We add the following application servers to the list of supported environments:
- Wildfly 10
- Oracle WebLogic 12c R2 (Enterprise Edition only)
- Version Tags for Process Definitions
- Fine-Grained Task Access Permissions
- Historic Identity Links
- Improved Fluent Builder for BPMN Model API
- Per-Process-Application Configuration of Object Variable Serialization
- 186 bugfixes
Read the release notes for a complete list of features.
Camunda 7.5.0 has a regression with the REST API resource for message correlation (see ticket CAM-6139). We will release Camunda 7.6.0-alpha1 with a bug fix in the near future.
