v0.33.0

⚠️ Breaking Changes

• iroh
  • removed
    • iroh::test_utils::create_dns_resolver is removed, use iroh::dns::DnsResolver::new instead
    • iroh::dns::resolver and iroh::dns::default_resolver are removed. There is no static, global DNS resolver anymore. If you want to share a DNS resolver between endpoints, create the resolver yourself with iroh::dns::DnsResolver::new and clone it into the endpoint builders (in EndpointBuilder::dns_resolver). If you want to reuse the DNS resolver from an endpoint, you can access it with Endpoint::dns_resolver and clone it to wherever you need it.
    • iroh::dns::node_info::{IrohAttr, TxtAttrs, node_id_from_hickory_name} are no longer public. Use iroh::dns::DnsResolver::lookup_node_by_id or iroh::dns::DnsResolver::lookup_node_by_domain_name to lookup node info from DNS.
    • iroh::dns::node_info::{to_z32, from_z32}are removed. Use the methods on iroh::dns::node_info::NodeIdExt trait instead.
    • iroh::dns::ResolverExt is removed. Use the methods on iroh::dns::DnsResolver instead.
    • iroh::discovery::Discovery::publish now takes data: &NodeData as its single argument. iroh::discovery::NodeData is a re-export of iroh_relay::dns::node_info::NodeData, and contains relay URL and direct addresses. See docs for NodeData for details.
    • iroh::Endpoint::connect_with was removed, use iroh::Endpoint::connect_with_opts instead
  • changed
    • iroh::dns::DnsResolver used to be a type alias and now is a reexport of iroh_relay::dns::DnsResolver struct
    • iroh::dns::node_info module is now a reexport of iroh_relay::dns::node_info
    • iroh::discovery::dns::{N0_DNS_NODE_ORIGIN_PROD, N0_DNS_NODE_ORIGIN_STAGING} are now reexports of iroh_relay::dns::{N0_DNS_NODE_ORIGIN_PROD, N0_DNS_NODE_ORIGIN_STAGING}
    • The methods in iroh::dns::DnsResolver now take an impl ToString instead of impl hickory_proto::rr::domain::IntoName for their host argument
    • iroh::discovery::DiscoveryItem no longer has any public fields. There are now getters for the contained data, and constructors for createing a DiscoveryItem from a NodeInfo.
    • iroh_relay::dns::node_info::NodeInfo is changed.
      • NodeInfo::new now has a single NodeId argument. Use NodeInfo::with_direct_addresses and NodeInfo::with_relay_url to set addresses and relay URL. Alternatively, use NodeInfo::from_parts and pass a NodeData struct.
      • NodeInfo now has two public fields node_id: NodeId and data: NodeData, and setter and getter methods for the relay URL and direct addresses.
    • iroh::discovery::pkarr::PkarrPublisher::update_addr_info now takes a NodeData argument
    • iroh::endpoint::Connection::into_0rtt now returns iroh::endpoint::ZeroRttAccepted, instead of iroh_quinn::ZeroRttAccepted
