What's New

Adds DoH/DoT support and reworked healthcheck system with auto-restart.

New Features

Healthcheck system rework with auto-restart on failure.
DNS over HTTPS (DoH) and DNS over TLS (DoT) support.
New `DNS_UPSTREAM_RESOLVER_TYPE` option for DNS configuration.
Local network names resolution for K8s users.
Port forwarding template variables for `{{PORT}}` and `{{VPN_INTERFACE}}`.

Improvements

Public IP data fetcher queries all data sources in parallel.
DNS over TLS reuses TCP connections to reduce stress.
Updated built-in server data for major VPN providers.
DNS requests blocked are now logged with a reason.
DNS rebinding protection is always enabled.

Upgrade Notes

You must configure the new healthcheck options such as `HEALTH_TARGET_ADDRESSES` and `HEALTH_ICMP_TARGET_IPS`. The DNS configuration now requires `DNS_UPSTREAM_RESOLVER_TYPE` to be set (dot, doh, or plain) to enable DoH or DoT support. Port forwarding templates now support `{{PORT}}` and `{{VPN_INTERFACE}}` variables.
