OpenBSD 7.7: A Compact Release with a Focus on Security and Support for New Hardware

The OpenBSD developers have released version 7.7, another step forward in the development of one of the most secure and stable operating systems. The developers continue their commitment to minimalism, conciseness, and security without excessive functional “noise”. The size of the full installation ISO image of the OpenBSD 7.7 base system is only 746 MB, and this is clear proof of the principles on which the project is based.

What's New in Version 7.7

The release includes kernel updates, improved support for the ARM64 and RISC-V architectures, and a number of new and updated drivers for modern hardware. This makes OpenBSD 7.7 even more versatile for use on both classic servers and embedded systems.

Security at the Kernel Level

Traditionally, the main focus is on security: the pledge and unveil mechanisms have been strengthened to restrict access rights for user programs. Memory protection tools have been extended, and internal checks in the compiler have been strengthened. All the changes are aimed at eliminating potential vulnerabilities, not post facto, but at the stage of system design.

Fresh Versions of Key Components

A number of key utilities have received updates: pfl, httpd, as well as tools from OpenSSH and LibreSSL. All of them now work faster, safer, and with improved configuration logic. At the same time, the usual file structure has been preserved — everything is very clear, documented, and tested over the years of operation.
