v0.7.0-beta.4

dquic v0.7.0-beta.4

Path admissibility

• Validate concrete QUIC paths before creating connection paths or accepting connectless initial packets.
• Preserve receive-side destination and IPv6 link-local scope evidence through UDP, interface, connection, and traversal layers.
• Keep outbound wildcard-source selection owned by the selected IO while rejecting invalid direct/link, address-family, scope, and loopback combinations.
• Report only accepted direct paths and prevent invalid connectless packets from consuming listener backlog or registering ODCIDs.

v0.7.0-beta.1

Beta release for the dquic transport line.

• Correct the qresolve::Publish abstraction boundary: publish implementations now own their wire format, packet construction, authentication, and backend-specific encoding details instead of requiring callers to construct publish packets across the trait boundary.

• Decouple the public publish contract from a specific packet format, making future backend migrations and test/mock publisher implementations easier.

• Advance qresolve, qtraversal, qconnection, and dquic to 0.7.0-beta.1 for the new resolver/transport compatibility line.

• Keep unchanged workspace members on their existing release lines.

v0.6.0

dquic v0.6.0

This release moves the dquic release-surface crates to the 0.6.0 compatibility line, centered on typed local endpoints, connection-owned path discovery, and safer connection/path lifecycle handling.

Highlights:

• Added typed local endpoint publishing in qinterface, replacing the generic location-event model.
• Routed observed local endpoint sets through qconnection's AddressBook so connection path discovery remains connection-owned.
• Reworked STUN endpoint advertisement in qtraversal around keyed, owned endpoint updates.
• Preserved partial path bursts instead of dropping already-loaded burst segments on later load errors.
• Terminated invalid pathless connections more explicitly.
• Exposed attempted connection state for callers that need to distinguish pre-establishment failure states.
• Reduced eager per-path allocation and lazily initialized packet-space dispatch.
• Released dropped location observers, closed connection resources, and ready IO wakers more reliably.
• Kept interface rebinding from reusing closed IO and avoided holding interface locks while notifying device subscribers.

Compatibility notes:

• Release-surface workspace crates are bumped to 0.6.0.
• qmacro intentionally remains on 0.5.1.
• h3-shim remains on 0.5.1 and is not part of the dquic release surface.
• qconnection local endpoint compatibility APIs were removed; callers should pass Locations at subscription sites and rely on the typed endpoint flow.

Release surface:

• dquic 0.6.0
• qbase 0.6.0
• qconnection 0.6.0
• qcongestion 0.6.0
• qdatagram 0.6.0
• qevent 0.6.0

v0.5.2-qconnection

qconnection 0.5.2

Staged member-crate release for qconnection.

This release publishes qconnection 0.5.2 only. The wider dquic workspace and dquic crate remain at 0.5.1.

Highlights

• Fixed connection close/termination cleanup paths so closing resources are finalized after PTO.
• Retained connections while closing, allowing delayed cleanup to complete reliably.
• Routed close events through connection state and termination ownership.
• Added final closed-state tracking so Closed waits for the real terminal state.
• Preserved silent close behavior for silent refusal paths.
• Added coverage for close handoff cleanup and silent close forwarding.

Downstream Impact

Downstreams using normal Cargo version requirements can pick up this patch with:

cargo update -p qconnection

Projects depending on dquic = "0.5.1" can also receive qconnection 0.5.2 transitively, because the published dquic 0.5.1 dependency requirement for qconnection is compatible with 0.5.2.

This will not update consumers that pin qconnection = "=0.5.1" or use a git/path/patch override.

Release Automation

• The publish workflow now selects only initialized crates with missing versions, so this staged tag publishes qconnection only.
• v* tag-triggered publish runs now create a GitHub Release automatically after the crates.io publish step succeeds.

Release Surface

• Published crate: qconnection 0.5.2
• Tag: v0.5.2-qconnection
• Repository target branch: main
• Publish path: tag-triggered Publish crates.io workflow

v0.5.1

dquic v0.5.1

This release focuses on traversal correctness, interface/bind semantics,
connection lifecycle cleanup, and workspace publish readiness across the
dquic stack.

Traversal and NAT maintenance

• qtraversal now refreshes receive-side routing dependencies correctly during
  reinit and interface rebind.
• NAT mappings are refreshed sooner to reduce stale external-address state.
• Local endpoints are now tracked in the traversal address book.
• STUN probe handling now uses typed errors instead of looser classification.
• Traversal verification was tightened to wait explicitly for STUN data.

These changes make punching, rebinding, and long-lived traversal sessions more
predictable under interface churn and mapping refresh.

Interface and UDP bind semantics

• qinterface no longer treats transient interface statistics (rx / tx
  counters and timestamps) as meaningful interface changes.
• Interface-bound UDP sockets are now bound to their devices more explicitly.
• qudp now treats inet://[::]:PORT as strict IPv6-only behavior.

Downstreams that need dual-stack exposure should bind IPv4 and IPv6
explicitly instead of relying on an IPv6 wildcard bind to cover both.

Connection lifecycle and timers

• dquic::common no longer blocks Network::bind on synchronous STUN
  resolution.
• qconnection now exposes Arc<Connection> directly and breaks the strong
  reference cycle that could keep connections alive after external owners were
  dropped.
• qconnection now exposes local punch endpoints.
• qbase idle-timer handling was corrected, including path-creation start
  behavior and incorrect send-side renewal.
• TLS terminology was normalized from agent to authority.
• connection auth log copy was normalized accordingly.

Resolver, protocol, and TLS surface

• a new qprotocol crate now carries routing / control protocol pieces
• qresolve resolver traits are now downcastable
• qresolve can distinguish H3 DNS sources more explicitly
• qresolve publish metadata now declares the required tokio/net feature set
• custom server certificate verification gained OCSP support

Workspace publish readiness

• the workspace publish surface was prepared for 0.5.1
• qprotocol publishing metadata now uses the workspace README
• unused dependencies were removed across workspace crates
• release workflow naming was normalized to publish
• the workspace publish workflow now supports sequential publish handling for
  the full crate set

Upgrade notes

• QuicClient / QuicListeners connection-returning APIs now expose
  Arc<Connection> directly
• inet://[::]:PORT is now IPv6-only
• TLS naming has been normalized from agent to authority
• the workspace now includes the new qprotocol crate

Full changelog: v0.5.0...v0.5.1

v0.5.0

dquic v0.5.0

The project has been renamed from gm-quic to dquic.

The private gm-quic-traversal fork is now merged into the main tree,
contributing two new crates:

• qtraversal — STUN client/server, hole punching, port prediction.
• qresolve — DNS resolver trait and implementation.

qunreliable has been renamed to qdatagram.

qinterface has been reworked around a BindUri-based identifier and
a component-oriented core, replacing the previous iface/local/factory layout.

Connection is now Clone, and the client connect path does multi-path
probing with async resolution. A new qconnection::traversal module
wires things into qtraversal. qbase gains frames for address management
and hole punching (add_address, remove_address, punch_hello,
punch_done, punch_me_now); ReceiveFrame/SendFrame move into frame::io;
*_FRAME_TYPE constants are replaced by WriteFrameType;
PacketContains is renamed to PacketContent.

The top-level dquic crate exposes per-interface STUN / relay configuration,
on-demand NAT detection, extended ToCertificate / ToPrivateKey
implementations, and a Router::close() for clean shutdown.
New traversal-client / traversal-server examples demonstrate the flow,
and the old inline tests have been extracted into tests/{auth,echo,traversal}.rs.

Notable fixes include STUN agent filtering by iface family,
a puncher deadlock resolved around address_book,
reliable direct PunchDone confirmation, client-only 0-RTT logging,
and renewed localhost test certificates.
Dependencies netdev, rand, reqwest, and nix were bumped.
CI gains traversal, commitlint, and feishu-bot workflows;
interop.yml is removed; the Docker image builds with cache.

Upgrade notes

• Rename dependencies: gm-quic → dquic, qunreliable → qdatagram.
• Migrate from the old qinterface::iface / local / factory modules
  to the new BindUri + component API.
• Replace *_FRAME_TYPE constants with WriteFrameType.
• Rename PacketContains to PacketContent.
