These include kernel improvements such as the addition of waitid(2), pinsyscall(2), getthrname(2) and setthrname(2) functions, and WTRAPPED option for waitid(2), among others. Additionally, the new kernel autoconf_serial sysctl(8) allows userland monitoring of kernel device tree state changes.

Direct Rendering Manager and graphics drivers have been updated, with the introduction of support for the Ryzen 7000 “Raphael” and Ryzen 7020 and 7045 series processors, as well as the Radeon RX 7900 XT/XTX “Navi 31”, and improvements to address issues on Apple Silicon laptops and the Lenovo x13s.

There is also improved support for network hardware, such as the enabled em(4) IPv4, TCP and UDP checksum offloading and hardware VLAN tagging on devices with 82575, 82576, i350 and i210 chipsets, as well as improved mcx(4) performance.
