 # Changelog
 
+## 2025-09-03 - 3.0.78 - fix(servertools)
+Fix wildcard path extraction for static/proxy handlers, correct serviceworker route, add local settings and test typo fix
+
+- Make HandlerProxy and HandlerStatic robust to Express 5 wildcard param shapes (handle req.params.splat, numeric params, req.baseUrl and root routes) to correctly compute relative paths
+- Change serviceworker route registration to use '/serviceworker/*splat' (instead of previous pattern) for consistent wildcard handling
+- Fix test wording typo in test/test.server.ts ('exposer' -> 'expose')
+- Add .claude/settings.local.json with local tool permissions and add .serena/.gitignore to ignore /cache
+
 ## 2025-08-17 - 3.0.77 - fix(servertools)
 Adjust route wildcard patterns and CORS handling; update serviceworker and SSL redirect patterns; bump express dependency; add local Claude settings
