Abada Engine v0.8.4-alpha Release Notes

Release Date: January 30, 2026
Status: Alpha Release
Focus: Tenda MVP & Platform Integration

Overview

Version 0.8.4-alpha marks a significant milestone in the Abada Platform roadmap: the transition from a "headless" engine to an integrated platform. This release introduces the first version of Abada Tenda (Tasklist UI) and provides a much-improved development experience for building full-stack workflow applications.

Roadmap Context: This release fulfills the second milestone in the Roadmap to Beta, focusing on the end-user task lifecycle.

What's New

🖥️ Abada Tenda Integration (MVP)

The engine now supports the initial release of Abada Tenda, our specialized Tasklist UI.

  • Task Lifecycle: Full support for claiming, completing, and managing user tasks via the UI.
  • Variable Handling: Users can now view input variables and submit output variables directly through Tenda.
  • Seamless Setup: Docker Compose now includes Tenda as a first-class service, pre-configured to communicate with the engine.

🛠️ Enhanced Process Management

We've expanded the Engine API to provide better control over running processes:

  • New Statuses: Introduced CANCELLED and SUSPENDED states for process instances.
  • Management Endpoints: Added dedicated API endpoints for instance management and job control.
  • External Task Failures: Improved reporting for external task failures, including error messages and retry logic.

🏗️ Improved Developer Experience (DX)

  • Flexible Docker Strategy: New dedicated Dockerfile.prod and streamlined dev/prod configurations.
  • Sibling Project Integration: The build-and-run-dev.sh script now automatically detects and builds sibling projects (abada-tenda, abada-orun) if they are present in the workspace.
  • Sample Data Generation: A new utility to populate the engine with realistic sample processes, tasks, and history for testing and demos.

🧪 Advanced Instrumentation

  • Process Starter Tracking: Track who started a process and identify candidate starter groups.
  • PostgreSQL Support: Added production-ready PostgreSQL driver and configuration for containerized deployments.

Technical Implementation

Core Changes

  • Refactored JobController to move management endpoints to /v1/jobs.
  • Moved cockpit-specific endpoints to a dedicated controller for better separation of concerns.
  • Implemented process instance suspension and cancellation logic in the core engine.

Infrastructure Update

  • Updated docker-compose.yml to include abada-tenda and abada-orun services.
  • Added data-local directory for persistent local development data.
  • Optimized OTLP span exporters for better Jaeger integration.

Documentation

Updated guides:

Bug Fixes

  • Fixed duplicate container name issues in development scripts.
  • Resolved suspended status flag confusion in the process engine logic.
  • Fixed process starter tracking for anonymous starts.
  • Corrected Grafana dashboard datasource UIDs to be case-insensitive.

What's Next

According to the Roadmap to Beta, the next major focus will be:

  • v0.8.5-alpha: Orun MVP (Cockpit UI) - Focus on history APIs and process monitoring.
  • v0.9.0-alpha: End-to-End Validation - Hardening the platform with complex, real-world business scenarios.
