We are excited to announce the release of Wallarm Node 5.0! This major update represents a significant shift in our technology stack, bringing enhanced performance and scalability to your Wallarm deployment.

Key Highlights:

• New Technology Stack: The Wallarm node has been re-engineered from a Ruby-based implementation to Go, resulting in a faster, more scalable, and resource-efficient solution.
• Performance Improvements: The Wallarm Postanalytics module’s performance has been improved:
  • CPU Usage: Reduced from 0.5 CPU cores to just 0.1 CPU cores.
  • Memory Usage: Lowered by 400 MB at a traffic rate of 500 requests per second.

File System Updates:

• Consolidated Logging: Logs from almost all services are now recorded in a single file, wcli-out.log, simplifying log management.
• Updated Diagnostic Script Path: The diagnostic script has been moved to /opt/wallarm/collect-info.sh from its previous location.

Important Notes:

• This release focuses on technical refactoring and does not introduce any changes in functionality. All features supported in the previous version (4.10) are retained in 5.0.
