+
+## [2.14.0] - 2025-09-26
+
+### Added
+- Anonymous telemetry system with Supabase integration to understand usage patterns
+  - Tracks active users with deterministic anonymous IDs
+  - Records MCP tool usage frequency and error rates
+  - Captures sanitized workflow structures on successful validation
+  - Monitors common error patterns for improvement insights
+  - Zero-configuration design with opt-out support via N8N_MCP_TELEMETRY_DISABLED environment variable
+
+- Enhanced telemetry tracking methods:
+  - `trackSearchQuery` - Records search patterns and result counts
+  - `trackValidationDetails` - Captures validation errors and warnings
+  - `trackToolSequence` - Tracks AI agent tool usage sequences
+  - `trackNodeConfiguration` - Records common node configuration patterns
+  - `trackPerformanceMetric` - Monitors operation performance
+
+- Privacy-focused workflow sanitization:
+  - Removes all sensitive data (URLs, API keys, credentials)
+  - Generates workflow hashes for deduplication
+  - Preserves only structural information
+
+- Comprehensive test coverage for telemetry components (91%+ coverage)
+
+### Fixed
+- Fixed TypeErrors in `get_node_info`, `get_node_essentials`, and `get_node_documentation` tools that were affecting 50% of calls
+- Added null safety checks for undefined node properties
+- Fixed multi-process telemetry issues with immediate flush strategy
+- Resolved RLS policy and permission issues with Supabase
+
+### Changed
+- Updated Docker configuration to include Supabase client for telemetry support
+- Enhanced workflow validation tools to track validated workflows
+- Improved error handling with proper null coalescing operators
+
+### Documentation
+- Added PRIVACY.md with comprehensive privacy policy
+- Added telemetry configuration instructions to README
+- Updated CLAUDE.md with telemetry system architecture
+
+## Previous Versions
