+- New header processing controls with include/exclude logic
+- Improved upstream selection with smarter address rotation
+- New message anonymization tools for privacy-conscious deployments

+
+## Critical Fixes and Security Updates
+
+Several important security and functionality fixes have been implemented:
+
+- Comprehensive fixes for RFC 2047 header encoding
+- Enhanced fuzzy storage security with improved dynamic key handling
+- Optimized TCP connection handling with cumulative timeouts
+- Strengthened DNS limit controls in SPF processing
+- Reduced false positives in phishing detection
+- Corrected DMARC structured headers encoding
+
+## Web Interface Improvements
+
+The web interface received significant usability updates:
+- Redesigned symbol description system with improved hover functionality
+- Enhanced keyboard navigation for accessibility
+- Modernized symbol rendering system
+- Improved user experience with clearer information display
+
+## Configuration and Administration
+
+New configuration capabilities have been added:
+- Introduction of `lua.local.d` folder for better organization
+- Extended configuration options for greater flexibility
+- Improved documentation and examples
+
+## Performance Optimizations
+
+Several performance-focused improvements have been implemented:
+- Optimized RBL checking logic
+- Refined multimap text part processing
+- Enhanced GPT module response parsing
+- Improved memory management and resource utilization
+
+## Installation and Upgrade Notes
+
+Users upgrading to version 3.11 should:
+1. Review Elasticsearch/OpenSearch configurations if using these features
+2. Test existing configurations with the new header processing logic
+3. Update any custom scripts that interact with ratelimiting features
+4. Review the new configuration options for potential optimizations
+
+The Rspamd team recommends testing the upgrade in a staging environment first, particularly if using the Elasticsearch integration.
+
+## Looking Forward
+
+This release represents a significant step forward in Rspamd's evolution, with particular focus on modern infrastructure support, security, and usability. The improvements to the Elasticsearch integration and the addition of new management tools provide a solid foundation for future enhancements.
