Box64 v0.4 was released, delivering significant improvements for running x86_64 Linux binaries on AArch64 Linux systems. Key enhancements in this version include better support for DRM protected games and increased stability when using Steam. The project aims to provide compatibility for a broader range of x86_64 software on ARM-based Linux distributions, with future development also targeting RISC-V architectures. Phoronix highlighted Box64's ongoing progress, stating it is "another great open-source project for running x86_64 Linux binaries on AArch64 Linux." This release strengthens its position as an alternative to projects like Valve-sponsored Fex-Emu.
