## Other Notable Changes {#sec-release-24.05-notable-changes}

<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. -->

- Programs written in [Nim](https://nim-lang.org/) are built with libraries selected by lockfiles.
  The `nimPackages` and `nim2Packages` sets have been removed.
  See https://nixos.org/manual/nixpkgs/unstable#nim for more information.

- The Yama LSM is now enabled by default in the kernel, which prevents ptracing
  non-child processes. This means you will not be able to attach gdb to an
  existing process, but will need to start that process from gdb (so it is a
  child). Or you can set `boot.kernel.sysctl."kernel.yama.ptrace_scope"` to 0.

- The `hardware.pulseaudio` module now sets permission of pulse user home directory to 755 when running in "systemWide" mode. It fixes [issue 114399](https://github.com/NixOS/nixpkgs/issues/114399).
