See https://github.com/mdlayher/netlink/blob/main/CHANGELOG.md#v1112

• [Bug Fix]: #291 fixed a bug where netlink.Conn.Receive would block concurrent calls to netlink.Conn.Send when blocking in recvmsg.
• [Improvement]: #289 updated golang.org/x/net and golang.org/x/sys dependencies.

See https://github.com/mdlayher/netlink/blob/main/CHANGELOG.md#v1111

• [Bug Fix]: #283 fixed a bug where netlink.Conn.Receive would reject valid netlink messages whose header length is not aligned. This is common with nfqueue, nflog and conntrack events.
• [Bug Fix]: #284 fixed a bug where netlink.Message.Data could be silently overwritten by subsequent netlink.Conn.Receive calls when netlink.Config.MessageBufferSize is enabled, due to pooled buffer reuse.
• [Improvement]: #282 improved error handling by usage of errors package.

See https://github.com/mdlayher/netlink/blob/main/CHANGELOG.md#v1110

This is the first release of package netlink that only supports Go 1.25+.

• [Bug Fix]: #280 fixed a critical bug where netlink.Conn.Receive and netlink.Conn.ReceiveIter would panic if the received message was unaligned.
• [Improvement]: #277 added big-endian test fixtures for nlenc and deprecated endian helpers in favor of binary.NativeEndian.
• [Improvement]: #276 fixed skipping of tests on big-endian hosts.
• [Improvement]: #273 added golangci-lint to the CI pipeline and fixed all existing lint issues.
• [Improvement]: #272 updated dependencies and Go version to 1.25.

See https://github.com/mdlayher/netlink/blob/main/CHANGELOG.md#v1100

Users of this version should upgrade to v1.11.0 as this version contains a critical bug.

• [New API]: #270 added MessageBufferSize option to netlink.Config for configuring the size of the copy buffer used for receiving messages. This can improve performance in high-throughput applications by reducing the number of syscalls needed to receive messages.
• [Improvement]: #219 added debug logging inspired by libmnl. This is now the new default when setting NLDEBUG in the environment.
• [New API]: #258 added netlink.Conn.ReceiveIter for iterating over responses without collecting them into a slice. It also optimized netlink.Conn.Receive to use this new API internally so that less memory is used.
• [Improvement]: #269 made it so nltest.Conn.Receive can be used to test that multi-part messages are drained properly.
• [Improvement]: #266 optimized the initial parsing of netlink messages in netlink.Socket.Receive by adding an iterator for parsing messages directly from the receive buffer.
• [Improvement]: #267 added integration test benchmarks for multi-part dumps.
• [Improvement]: #215 optimized the internal peek/allocate logic in netlink.Socket.Receive. Messages are no longer being copied during peeking and the buffer is allocated to the exact size of the upcoming message.
• [Bug Fix]: #265 fixed a bug where concurrent calls to netlink.Conn.Receive could race with each other when handling multi-part messages. Calls to Receive are now serialized.
• [Improvement]: #264 added handling for truncated messages in netlink.Socket.Receive.

See https://github.com/mdlayher/netlink/blob/main/CHANGELOG.md#v190.

This is the first release of package netlink that only supports Go 1.24+.

• [Improvement]: updated dependencies and Go version to 1.24; tests now run on Go 1.24-1.26.
• [New API]: #236 introduced Sequence field to OpError for better error correlation.
• [New API]: #237 added netlink.Conn.PID method to retrieve the connection's PID, also known as port ID.
• [Improvement]: #228 fixed skipping of specific tests on big-endian hosts.

See https://github.com/mdlayher/netlink/blob/main/CHANGELOG.md#v180.

• [Improvement]: Updated dependencies, test with Go 1.23 to 1.25.
• [Improvement]: Use Go 1.21's binary.NativeEndian (#220)
• [Improvement]: Expose socket ReadBuffer & WriteBuffer functions (#223)

See https://github.com/mdlayher/netlink/blob/main/CHANGELOG.md#v172.

• [Improvement]: updated dependencies, test with Go 1.20.

See https://github.com/mdlayher/netlink/blob/main/CHANGELOG.md#v171.

• [Bug Fix]: test only changes to avoid failures on big endian machines.

See https://github.com/mdlayher/netlink/blob/main/CHANGELOG.md#v170.

This is the first release of package netlink that only supports Go 1.18+. Users on older versions of Go must use v1.6.2.

• [Improvement]: drop support for older versions of Go so we can begin using modern versions of x/sys and other dependencies.

See https://github.com/mdlayher/netlink/blob/main/CHANGELOG.md#v162.

This is the last release of package netlink that supports Go 1.17 and below.

• [Bug Fix] commit: undo update to golang.org/x/sys which would force the minimum Go version of this package to Go 1.17 due to use of unsafe.Slice. We encourage users to use the latest stable version of Go where possible, but continue to maintain some compatibility with older versions of Go as long as it is reasonable to do so.

• [Deprecation] commit: the netlink.Socket interface has been marked as deprecated. The abstraction is awkward to use properly and disables much of the functionality of the Conn type when the basic interface is implemented. Do not use.

This is the first release of package netlink that only supports Go 1.13+. Users on older versions of Go must use v1.5.0.

• [New API] commit: the netlink.Config.Strict field can be used to apply a more strict default set of options to a netlink.Conn. This is recommended for applications running on modern Linux kernels, but cannot be enabled by default because the options may require a more recent kernel than the minimum kernel version that Go supports. See the documentation for details.
• [Improvement]: broke some integration tests into a separate Go module so the default go.mod for package netlink has fewer dependencies.
