v0.16.0

What's New in v0.16.0

This release introduces configurable logging and comprehensive data flow tracing with correlation IDs, making it easier to debug and monitor event processing in production environments.

New Features

Configurable Log Levels

All Fiso binaries now support configurable log levels:

• --log-level flag: Set the logging verbosity directly via command line

  fiso-flow --log-level debug
  fiso-link --log-level info
  fiso-operator --log-level warn

• FISO_LOG_LEVEL environment variable: Configure log levels without modifying command-line arguments

  export FISO_LOG_LEVEL=debug
  fiso-flow

Supported log levels: trace, debug, info, warn, error

Comprehensive Data Flow Logging with Correlation IDs

Fiso now tracks events throughout the entire processing pipeline using correlation IDs:

• Correlation ID Propagation: Events carry correlation IDs through the entire event pipeline, from ingestion to delivery
• INFO-level Logging: Event processing and delivery operations are logged at INFO level for production visibility
• Latency Tracking: Logs include latency measurements for performance monitoring

Supported Correlation Headers

Fiso automatically extracts and propagates correlation IDs from standard headers:

• fiso-correlation-id (Fiso native)
• x-correlation-id (common standard)
• x-request-id (HTTP standard)
• traceparent (W3C Trace Context)

Upgrade Notes

No breaking changes in this release. Simply update your binaries to take advantage of the new logging capabilities.
