 Support for man:ptrace[2] is now available for Linux processes on arm64.
 gitref:99950e8beb72[repository=src]
 
+In order to facilitate ABI compatibility of `stable` branches, the CPU affinity system calls are now more tolerant of CPU sets that are smaller than used by the kernel.
+This will facilitate increases to the size of the kernel set, `MAXCPU`.

+64-bit man:linux[4] ABI support was added for saving CPU floating point state across signal delivery.

 vDSO (virtual dynamic shared object) support has been nearly completed in the man:linux[4] ABI.
-The system calls for man:gettimeofday[2], man:clock_gettime[2], all *_time64() calls, and getcpu() are now implemented in the vDSO, avoiding system call overhead.
-Unimplemented vDSO system calls fall back to the kernel system calls.
-The thread affinity system calls were modified to support Linux semantics.
-The arm64 Linux support has been brought to parity with amd64.
