# Version 0.16.0 (2025-08-04)
|
|||
|
|
|
|||
|
|
This release introduces initial support for the **LoongArch CPU architecture**, a major milestone for the project. Version 0.16.0 also significantly expands our Linux ABI compatibility with the addition of **nine new system calls** such as `memfd_create` and `pidfd_open`.
|
|||
|
|
|
|||
|
|
Key enhancements include expanded functionality for **UNIX sockets (file descriptor passing and the `SOCK_SEQPACKET` socket type)**, partial support for **netlink sockets of the `NETLINK_KOBJECT_UEVENT` type**, the initial implementation of **CgroupFS**, and a major testing improvement with the integration of system call tests from the **Linux Test Project (LTP)**. We've also adopted **[Nix](https://nix.dev/manual/nix/2.28/introduction)** for building the initramfs, streamlining our cross-compilation and testing workflow.
