-  ([#1946](https://github.com/nix-rust/nix/pull/1946))
-
-- Fixed the function signature of `recvmmsg`, potentially causing UB
-  ([#2119](https://github.com/nix-rust/nix/issues/2119))

-  descriptor.
-  ([#2141](https://github.com/nix-rust/nix/pull/2141))
-
-### Changed
-
-- Changed function `SockaddrIn::ip()` to return `net::Ipv4Addr` and 
-  refactored `SocketAddrV6::ip()` to use `const`
-  ([#2151](https://github.com/nix-rust/nix/pull/2151))
-
-- The MSRV is now 1.69
-  ([#2144](https://github.com/nix-rust/nix/pull/2144))
-
-- The following APIs now take an implementation of `AsFd` rather than a

-  - `unistd::tcsetpgrp`
-  - `unistd::fpathconf`
-  - `unistd::ttyname`
-  - `unistd::getpeereid`
-
-  ([#2137](https://github.com/nix-rust/nix/pull/2137))
-
-- Changed `openat()` and `Dir::openat()`, now take optional `dirfd`s
-  ([#2139](https://github.com/nix-rust/nix/pull/2139))
-
-- `PollFd::new` now takes a `BorrowedFd` argument, with relaxed lifetime
-  requirements relative to the previous version.
-  ([#2134](https://github.com/nix-rust/nix/pull/2134))
-
-- `FdSet::{insert, remove, contains}` now take `BorrowedFd` arguments, and have

-
-- Simplified the function signatures of `recvmmsg` and `sendmmsg`
-
-### Added
-- Added `Icmp` and `IcmpV6` to `SockProtocol`.
-  (#[2103](https://github.com/nix-rust/nix/pull/2103))
