We are pleased to announce the official release of OpenBSD 7.5. This is our 56th release. We remain proud of OpenBSD's record of more than twenty years with only two remote holes in the default install. As in our previous releases, 7.5 provides significant improvements, including new features, in nearly all areas of the system: added bt(5) and btrace(8) support for binary modulo operator; added a TIMEOUT_MPSAFE flag to timeout(9); added IBM encoded version of the "Spleen 8x16" font, usable as console font; cleanup and machine-independent refactoring of three context switch paths outside of mi_switch(): when a process forks and the new proc needs to be scheduled by proc_trampoline, cpu_hatch: when booting APs, and sched_exit: when a proc exits; made vscsi(4) 'vscsi_filtops' mpsafe and extended the 'sc_state_mtx' mutex(9) to protect 'sc_klist' knotes list; made out-of-swap checking more robust, preventing potential deadlocks....
