Release notes

Sourced from smoltcp's releases.

v0.13.0

Highlights of this release are IPv6 SLAAC support, TCP improvements (zero window probes, retransmit fixes, RFC compliance), raw socket enhancements, and a bump to Rust Edition 2024.

• Minimum Supported Rust Version (MSRV) bumped to 1.91.
• Rust Edition bumped to 2024. (#1084)
• heapless dependency bumped to v0.9. (#1083)
• iface
  • IPv6 SLAAC (Stateless Address Autoconfiguration), gated behind a new slaac feature flag. (#1039)
  • Add slaac_updated_at method to check when SLAAC addresses were last updated. (#1130)
  • Add getters for the default IPv4/IPv6 route and is_ipv4_gateway/is_ipv6_gateway helpers. (#1129)
  • Exhaust egress socket state on poll, so sockets don't have to wait for the next poll to send queued data. (#1059)
  • Remove always-Ok Results in consume(). (#1093)
  • Honor any_ip when checking local address. (#1119)
  • Add iface_max_route_count-0 feature flag to disable the routing table entirely. (#1057)
  • Improve IPv4 source address selection for multi-subnet interfaces. (#1074)
  • Fix poll_at returning stale timestamps due to silent_until expiry check. (#1127)
  • Fix fragment payload sizes not being a multiple of eight octets. (#1116)
  • Fix incorrect packet length after defragmentation. (#1094)
  • Fix compilation of IPv6+Multicast without Ethernet. (#1043)
  • Log and drop IPv6 packets requiring fragmentation (IPv6 routers must not fragment). (#1038)
• tcp
  • Add zero window probe support. (#1026)
  • Close socket if the local IP is no longer assigned to the interface. (#1113)
  • Reject bytes outside the receive window. (#1079)
  • Don't accept RST packets on listening sockets. (#1058)
  • Don't send TCP RST when packet is handled by a raw socket. (#1069)
  • Send challenge ACK for duplicate ACK in LAST-ACK state. (#1126)
  • Fix retransmit exponential backoff, align to RFC 6298. (#1023)
  • Restart retransmit timer on new data ACK. (#1018)
  • Fix FIN retransmit in CLOSING state. (#1026)
  • Add pause_synack feature flag to allow user code to withhold SYN|ACK. (#1063)
• socket
  • ICMP: support binding to a TCP port. (#1089)
  • ICMP: add no-auto-icmp-echo-reply feature flag to disable automatic echo replies. (#1106)
  • Raw: allow receiving all protocols and IP versions (unfiltered mode). (#1067)
  • Raw: fix panic when payload buffer exceeds packet size during fragmentation. (#1077)
  • DHCPv4: reuse DHCPOFFER transaction ID in DHCPREQUEST. (#1061)
  • DHCPv4: fix panic when T1 < T2 < lease duration is not respected by server. (#1029)
  • DNS: fix compilation when socket-dns is enabled but socket-udp isn't. (#1041)
  • Implement AnySocket for the Socket enum. (#1092)
• phy
  • Tracer: update public API to allow custom inspection and printing of packets. (#1076)
  • TunTapInterface: no longer automatically enables medium-ethernet feature. (#1055)
• wire
  • Add generic IPv4/IPv6 packet parsing support to IpRepr. (#1087)
  • Make Cidr initialization const. (#1036)
  • Add conversion from Endpoint into SocketAddr. (#1124)
  • Use newly stable IP methods from core::net. (#1115)
  • Fix RawHardwareAddress panic when parsing to specific link-layer address. (#1027)

Changelog

Sourced from smoltcp's changelog.

[0.13.1] - 2026-05-01

• tcp: Fix panic when a listening socket receives a SYN from the unspecified addr.
• tcp: fix SACK sequence number overflow, which could cause a panic when compiling with overflow checks enabled.
• ipv4: Check IPv4 IHL to be at least 20 bytes.
