 * v3 onion addresses used in pathnames are now truncated at 20 chars of onion, rather than 30 overall, to make shorter pathnames for unix domain sockets

 * default behaviour changed:
   * onion HTTPS certificates are now installed in per-onion pathnames
   * for instance `/projects.d/PROJECTNAME.d/ssl.d/ONIONADDRESS.onion.pem`, for each ONIONADDRESS in PROJECTNAME
-* if you are using 'combo' certificates, where a single certificate contains all SubjectAltNames for all onion addresses in the project
-  * do `set ssl_cert_each_onion 0` in the configuration, to re-enable combo cert handling
-  * now: combo-certificate goes into `projects.d/PROJECTNAME.d/ssl.d/PROJECTNAME.pem`
+* if you are using 'multi' certificates, where a single certificate contains all SubjectAltNames for all onion addresses in the project
