Fixed

• General memory performance improvements.

Fixed

• Race conditions on message ID in DNS-over-HTTPS and DNS-over-QUIC upstream implementations (#402).

Added

• proxy.Config struct now contains the new slog.Logger field which is used as the base logger for proxy service. If nil, slog.Default is used.
• upstream.Options with those you can configure the upstream properties now contain a new slog.Logger field which is used as the base logger during configuration and parsing processes. If nil, slog.Default is used.

Changed

• proxy.Config.UpstreamMode which determines the logic for upstreams has been changed, it is now of type proxy.UpstreamMode. If not specified the proxy.UpstreamModeLoadBalance is used.
• proxy.CheckDisabledAAAARequest has been deprecated, use proxy.RequestHandler instead.
• fastip.NewFastestAddr which initializes a new instance of fastip.FastestAddr is deprecated, use fastip.New instead.
• upstream.NewDefaultHostsResolver has been changed. Now it requires a non-nil slog.Logger as an additional argument.

Removed

• proxy.UModeLoadBalance, proxy.UModeParallel and proxy.UModeFastestAddr have been removed. Use the new corresponding type proxy.UpstreamMode.
• Deprecated proxy.Init has been removed.
• Deprecated upstream.LookupParallel has been removed.

Changed

• The quic-go dependency has been updated to v0.44.0.

Fixed

• Ignored wildcard specifications for top-level domains.

Fixed

• The quic-go dependency has been updated due to issues with QUIC and HTTP/3 upstreams on older Linux kernel versions.
• Domain specifications for top-level domains now considered when routing the requests for unqualified names.

Changed

• SOA and NS requests containing ARPA domains implying private IP addresses are now treated as private requests, as was previously the case only for PTR requests.
• proxy.DNSContext.RequestedPrivateRDNS is now set for SOA and NS requests, as was previously the case only for PTR requests.

Fixed

• Error-prone proxy.BeforeRequestError API. See documentation.

Fixed

• Validations in proxy.New performed with the default values, not the ones from configuration.

Added

• New proxy.BeforeRequestError type for the errors containing a custom DNS response. See proxy.BeforeRequestHandler for usage.

Changed

• The quic-go dependency has been updated to v0.42.0.
• proxy.BeforeRequestHandler is now an interface instead of a callback, and its the only method also differs in signature.

Fixed

• Unspecified IP addresses no more checked when using proxy.UModeFastestAddr.
