Release Notes¶

Version 1.3.0¶

Block Status Monitoring Service Integration: New monitoring service integration for real-time block status updates
Visualize individual block execution states and communication points
Enhanced Execution Parameters Visualization:
Full visibility of workflow start and run parameters in monitoring view
Detailed execution settings display with better layout and readability

PROOF-Importer Integration: Replaced data.sql with proof-importer for database initialization
More robust and maintainable approach for initial data population
Standard Templates: Added more standard templates and updated default values

Template Usage Visualization: View all workflows and blocks that depend on a specific template
Prevents accidental deletion of in-use templates
Alphabetical Sorting: Consistent sorting across all tables and lists
Inputs displayed alphabetically in template editor and block configuration
Executions sorted by startedAt timestamp

Loop Handling Improvements: Added startValue field for inputs to support iterative/loop scenarios
Enables proper initialization of inputs that participate in feedback loops
Distinguishes between static initial parameters and runtime execution values
Default field: Added defaultValue field for static and non-static inputs
Used when no input value arrives in the expected time period
Mandatory for optional static inputs
Java Wrapper Implementation: New Java wrapper for Java-based model program execution
Fixed command parsing to avoid jar startup issues
Input/Output Type Improvements:
New array data types: STRING_ARRAY, INTEGER_ARRAY, FLOAT_ARRAY, OBJECT_ARRAY
FILE_NAME type support for file parameter handling
Synchronization Strategy Extension: Add new strategy ALL_VALUES
ALL_VALUES triggers model execution when all required values are available

Block Container Memory Management: Fixed block container map clearing before re-population
Prevents memory leaks from accumulated block references
Ensures proper cleanup between workflow executions
Synchronized Input Access: Thread-safe access to currentInputs map in worker
Prevents race conditions in concurrent input handling
Improves stability under load
Error Step Handling: Corrected ERROR_STEP emission logic
Only sends ERROR_STEP on actual timeout when waiting for inputs
Reduces false positive error states

MQTT Integration:
New MQTT Subscriber and Publisher attachments for IoT and real-time data streaming integration
EBM (Energy Building Model) Workflow Support:
New workflow templates for energy building model simulations and research workflows
Workflow Naming Convention: Demo workflows now clearly marked with demo_ prefix

Block Parameter Overrides: Blocks can now override template defaults with fine-grained control
Customize container image per block
Configure sync strategy at block level
Mark shutdown-relevant parameters
Track which values differ from template defaults
Improved Block Visualization: Enhanced visual representation of block properties in the editor
Better parameter visibility

Comprehensive Monitoring View:
Full execution parameters and settings visualization
Enhanced ExecutionSettingsPanel with workflow start and run parameters
Better visibility into execution configuration and state
Improved parameter display for debugging and analysis
Consistent Data Organization:
Alphabetical sorting of inputs in template editor and configuration
Alphabetical sorting of blocks in configuration views
Alphabetical sorting of templates in usage lists
Improved discoverability and consistency across UI
Template Management Dialog: Simplified and enhanced templates display with better UX
Enhanced Localization: Complete multi-language support (English/German) for all new features
Template Usage Tracking:
View all workflows and blocks that depend on a specific template
Prevents accidental deletion of in-use templates with dependency visualization
Enhanced template management with usage information in the UI

Adjusted block logging queue names for consistency
Added robust error handling for block status updates in orchestrator
Prevents orchestrator crashes from individual block errors
Fixed block container map that was preventing memory cleanup across multiple workflow runs

Improved Bundle Size Management: UI redesigned with better code organization

MQTT Library Support: paho-mqtt integration for IoT communication patterns

Execution Export: Export complete workflow executions as ZIP files, including all configurations and attachments
Non-admin users can export their executions
Execution Progress Tracking: Real-time visualization of execution progress with communication point (CP) tracking
Current communication point is stored in the database during execution
Progress bars and visualizations in the monitoring interface
Execution Logging: Enhanced logging capabilities for debugging and monitoring workflow executions

User Data Directory: New dedicated userdata directory for user-managed files accessible by workflow blocks (e.g., FileReader)
Attachments Directory: Separate attachments directory for workflow-specific attachments with subdirectory support
File Upload/Download API: New file controller endpoints for uploading and downloading files via the API
Enhanced Attachment Handling: Improved attachment paths and ZIP entry handling during execution export

Configurable Shutdown Timeout: Users can now configure the shutdown timeout for workflows via configuration settings
PROOF_DIR Environment Variable: Support for custom PROOF directory paths via environment variables
