### Changes
- iface: rewrite `IpPacket` such that IPv6 packets can contain owned extension headers ([#802](https://github.com/smoltcp-rs/smoltcp/pull/802)).
- iface: remove generic `T: [u8]` in functions. This reduced the server example by 10KB ([#810](https://github.com/smoltcp-rs/smoltcp/pull/810)).

- sockets: `recv_slice` returns `RcvError::Truncated` when the length of the slice is smaller than the data received by the socket ([#859](https://github.com/smoltcp-rs/smoltcp/pull/859)).
- iface/ipv6: `get_source_address` uses [RFC 6724](https://www.rfc-editor.org/rfc/rfc6724) for address selection ([#864](https://github.com/smoltcp-rs/smoltcp/pull/864)).

## [0.10.0] - 2023-06-26
- Add optional packet metadata. Allows tracking packets by ID across the whole stack, between the `Device` impl and sockets. One application is timestamping packets with the PHY's collaboration, allowing implementing PTP (#628)
- Work-in-progress implementation of RPL (Routing Protocol for Low-Power and Lossy Networks), commonly used for IEEE 802.15.4 / 6LoWPAN networks. Wire is mostly complete, full functionality will be in 0.11 hopefully! (#627, #766, #767, #772, #773, #777, #790, #798, #804)
- dhcp: Add support for rebinding (#744)
- iface:
- add support for sending to subnet-local broadcast addrs (like 192.168.1.255). (#801)
- Creating an interface requires passing in the time. (#799)
- fix wrong payload length of first IPv4 fragment (#791, #792)
- Don't discard from unspecified IPv4 src addresses (#787)
- tcp:
- do not count window updates as duplicate acks. (#748)
- consider segments partially overlapping the window as acceptable (#749)
- Perform a reset() after an abort() (#788)
- 6lowpan:
- Hop-by-Hop Header compression (#765)
- Routing Header compression (#770)
- wire:
- reexport DNS opcode, rcode, flag. (#763, #806)
- refactor IPv6 Extension Headers to make them more consistent and easier to parse. (#781)
- check length field of NDISC redirected head (#784)
- Modify `hardware_addr` and `neighbor_cache` to be not `Option`, add `HardwareAddress::Ip` (#745)
- Add file descriptor support for tuntap devices, needed for the Android VPN API. (#776)
- implement Display and Error for error types (#750, #756, #757)
- Better defmt for Instant, Duration and Ipv6Address (#754, #758)
- Add Hash trait for enum_with_unknown macro (#755)
## [0.9.1] - 2023-02-08
- iface: make MulticastError public. (#747)
- Fix parsing of ieee802154 link layer address for NDISC options (#746)
## [0.9.0] - 2023-02-06
- Minimum Supported Rust Version (MSRV) **bumped** from 1.56 to 1.65
- Added DNS client support.
- Add DnsSocket (#465)
- Add support for one-shot mDNS resolution (#669)
- Added support for packet fragmentation and reassembly, both for IPv4 and 6LoWPAN. (#591, #580, #624, #634, #645, #653, #684)
- Major error handling overhaul.
- Previously, _smoltcp_ had a single `Error` enum that all methods returned. Now methods that can fail have their own error enums, with only the actual errors they can return. (#617, #667, #730)
- Consuming `phy::Device` tokens is now infallible.
- In the case of "buffer full", `phy::Device` implementations must return `None` from the `transmit`/`receive` methods. (Previously, they could either do that, or return tokens and then return `Error::Exhausted` when consuming them. The latter wasted computation since it'd make _smoltcp_ pointlessly spend effort preparing the packet, and is now disallowed).
- For all other phy errors, `phy::Device` implementations should drop the packet and handle the error themselves. (Either log it and forget it, or buffer/count it and offer methods to let the user retrieve the error queue/counts.) Returning the error to have it bubble up to `Interface::poll()` is no longer supported.
- phy: the `trait Device` now uses Generic Associated Types (GAT) for the TX and RX tokens. The main impact of this is `Device` impls can now borrow data (because previously, the`for<'a> T: Device<'a>` bounds required to workaround the lack of GATs essentially implied `T: 'static`.) (#572)
- iface: The `Interface` API has been significantly simplified and cleaned up.
- The builder has been removed (#736)
- SocketSet and Device are now borrowed in methods that need them, instead of owning them. (#619)
- `Interface` now owns the list of addresses (#719), routes, neighbor cache (#722), 6LoWPAN address contexts, and fragmentation buffers (#736) instead of borrowing them with `managed`.
- A new compile-time configuration mechanism has been added, to configure the size of the (now owned) buffers (#742)
- iface: Change neighbor discovery timeout from 3s to 1s, to match Linux's behavior. (#620)
- iface: Remove implicit sized bound on device generics (#679)
- iface/6lowpan: Add address context information for resolving 6LoWPAN addresses (#687)
- iface/6lowpan: fix incorrect SAM value in IPHC when address is not compressed (#630)
- iface/6lowpan: packet parsing fuzz fixes (#636)
- socket: Add send_with to udp, raw, and icmp sockets. These methods enable reserving a packet buffer with a greater size than you need, and then shrinking the size once you know it. (#625)
- socket: Make `trait AnySocket` object-safe (#718)
- socket/dhcpv4: add waker support (#623)
- socket/dhcpv4: indicate new config if there's a packet buffer provided (#685)
- socket/dhcpv4: Use renewal time from DHCP server ACK, if given (#683)
- socket/dhcpv4: allow for extra configuration
- setting arbitrary options in the request. (#650)
- retrieving arbitrary options from the response. (#650)
- setting custom parameter request list. (#650)
- setting custom timing for retries. (#650)
- Allow specifying different server/client DHCP ports (#738)
- socket/raw: Add `peek` and `peek_slice` methods (#734)
- socket/raw: When sending packets, send the source IP address unmodified (it was previously replaced with the interface's address if it was unspecified). (#616)
- socket/tcp: Do not reset socket-level settings, such as keepalive, on reset (#603)
- socket/tcp: ensure we always accept the segment at offset=0 even if the assembler is full. (#735, #452)
- socket/tcp: Refactored assembler, now more robust and faster (#726, #735)
- socket/udp: accept packets with checksum field set to `0`, since that means the checksum is not computed (#632)
- wire: make many functions const (#693)
- wire/dhcpv4: remove Option enum (#656)
- wire/dhcpv4: use heapless Vec for DNS server list (#678)
- wire/icmpv4: add support for TimeExceeded packets (#609)
- wire/ip: Remove `IpRepr::Unspecified`, `IpVersion::Unspecified`, `IpAddress::Unspecified` (#579, #616)
- wire/ip: support parsing unspecified IPv6 IpEndpoints from string (like `[::]:12345`) (#732)
- wire/ipv6: Make Public Ipv6RoutingType (#691)
- wire/ndisc: do not error on unrecognized options. (#737)
- Switch to Rust 2021 edition. (#729)
- Remove obsolete Cargo feature `rust-1_28` (#725)

## [0.7.0] - 2021-01-20
- Minimum Supported Rust Version (MSRV) **bumped** from 1.36 to 1.40
### New features
- tcp: Allow distinguishing between graceful (FIN) and ungraceful (RST) close. On graceful close, `recv()` now returns `Error::Finished`. On ungraceful close, `Error::Illegal` is returned, as before. ([351](https://github.com/smoltcp-rs/smoltcp/pull/351))
- sockets: Add support for attaching async/await Wakers to sockets. Wakers are woken on socket state changes. ([394](https://github.com/smoltcp-rs/smoltcp/pull/394))
- tcp: Set retransmission timeout based on an RTT estimation, instead of the previously fixed 100ms. This improves performance on high-latency links, such as mobile networks. ([406](https://github.com/smoltcp-rs/smoltcp/pull/406))
- tcp: add Delayed ACK support. On by default, with a 10ms delay. ([404](https://github.com/smoltcp-rs/smoltcp/pull/404))
- ip: Process broadcast packets directed to the subnet's broadcast address, such as 192.168.1.255. Previously broadcast packets were
only processed when directed to the 255.255.255.255 address. ([377](https://github.com/smoltcp-rs/smoltcp/pull/377))
### Fixes
- udp,raw,icmp: Fix packet buffer panic caused by large payload ([332](https://github.com/smoltcp-rs/smoltcp/pull/332))

- dhcpv4: Re-export dhcp::clientv4::Config
- dhcpv4: Enable `proto-dhcpv4` feature by default. ([327](https://github.com/smoltcp-rs/smoltcp/pull/327))

- ethernet,arp: Only limit the neighbor cache rate after sending a request packet ([369](https://github.com/smoltcp-rs/smoltcp/pull/369))
- tcp: use provided ip for TcpSocket::connect instead of 0.0.0.0 ([329](https://github.com/smoltcp-rs/smoltcp/pull/329))
- tcp: Accept data packets in FIN_WAIT_2 state. ([350](https://github.com/smoltcp-rs/smoltcp/pull/350))
- tcp: Always send updated ack number in `ack_reply()`. ([353](https://github.com/smoltcp-rs/smoltcp/pull/353))
