Release Highlights - 2025.2

Secure Database Connection Management

Enhanced security for On-Prem customers with a new option to handle database connection strings through environment variables alongside the existing plaintext configuration files. This approach:

  • Provides flexibility to choose between plaintext configuration or more secure environment variables
  • Significantly reduces attack surface by removing sensitive credentials from configuration files
  • Simplifies configuration using the %CALUMO_CONNECTION_STRING% environment variable reference in master.config.json

Visit Secure the Connection String - Documentation to learn more about implementing this security enhancement and which method best suits your environment.

Enhanced Excel Function Capabilities

CREPORTUPLOAD File Type Configuration

Administrators now have greater control over file uploads with the ability to specify allowed file types for the CREPORTUPLOAD function:

  • By default, all file types are permitted
  • Restrict uploads by specifying file extensions in the “Allowed Upload File Types” field
  • Configuration available in server configuration settings

See Application Settings - Documentation for detailed configuration instructions.

CTODAY() Function Consistency

The CTODAY() function has been enhanced for greater consistency:

  • Ensures consistent behavior across both web and Excel clients
  • Improved date formatting in the Excel client for better readability
  • Comprehensive documentation now available to help users get the most from this feature

Learn more about this function in CTODAY - Documentation.

CALUMO Code Signing System: DigiCert STM Integration

Significant enhancements to CALUMO’s code signing system to ensure robust security and streamlined operations:

  • Enhanced Security: Transitioned to DigiCert STM for production environments, providing a secure, industry-standard solution for signing processes. Credentials are securely managed.

  • Efficient and Auditable Signing: Leveraged DigiCert STM to enable automated and traceable signing workflows, ensuring compliance and operational transparency across production environments.

Advanced OLAP Connection Logging

Significantly improved logging capabilities for Calumo’s OLAP connections that facilitate better traceability and diagnostics:

  • Enhanced Session Type Detection: A cached SessionTypePatterns dictionary identifies various connection string patterns (Azure, PowerBI, HTTP/HTTPS, XMLA) and returns a structured session type, simplifying future extensions to session type recognition.

  • Structured Logging Methods: New standardized logging practices include clear, structured messages encompassing datasource, session type, and user context.

These improvements significantly enhance the overall maintainability, robustness, and clarity of the OLAP session creation and error reporting mechanisms.
