 # Changelog
 
+## 2026-02-13 - 5.4.2 - fix(dcrouter)
+improve domain pattern matching to support routing-glob and wildcard patterns and use matching logic when resolving routes
+
+- Support routing-glob patterns beginning with '*' (e.g. *example.com) to match base domain, wildcard form, and subdomains
+- Treat standard wildcard patterns ('*.example.com') as matching both the base domain (example.com) and its subdomains
+- Use isDomainMatch when resolving routes instead of exact array includes to allow pattern matching
+- Normalize domain and pattern to lowercase and simplify equality checks
+
 ## 2026-02-13 - 5.4.1 - fix(network,dcrouter)
 Always register SmartProxy certificate event handlers and include total bytes + improved connection metrics in network stats/UI
