 # Changelog
 
+## 2025-03-12 - 3.41.6 - fix(SniHandler)
+Refactor SniHandler: update whitespace, comment formatting, and consistent type definitions
+
+- Unified inline comment style and spacing in SniHandler
+- Refactored session cache type declaration for clarity
+- Adjusted buffer length calculations to include TLS record header consistently
+- Minor improvements to logging messages during ClientHello reassembly and SNI extraction
+
 ## 2025-03-12 - 3.41.5 - fix(portproxy)
 Enforce TLS handshake and SNI validation on port 443 by blocking non-TLS connections and terminating session resumption attempts without SNI when allowSessionTicket is disabled.
