New Features
2- Domain Aliases: publish an existing website under additional hostnames without creating a separate vhost or docroot. The alias hostname is appended to the target domain vhost server_name; it is a mirror, not a redirect.
- Conflict guard: an alias hostname that already exists as a domain, subdomain, or another alias is rejected before it can be applied, structurally preventing the class of Nginx conflicting-server-name errors reported by customers.
Improvement
1- SSL: active aliases (and their www variants) are automatically added to the domain certificate SAN list when they already resolve via DNS. Adding a new alias triggers a best-effort automatic re-issue that never breaks an existing certificate — it only replaces it on success.
Bug Fix
1- Startup self-heal (SH-111): if an alias server_name entry is ever missing from the live Nginx vhost after an update or manual edit, the backend restores it automatically on the next restart, so alias delivery survives updates.
