+Version 1.7 (2016-05-18)
+
+The code has been updated to work with newer versions of GCC, and numerous bugs
+have been fixed throughout the code, including a pageout deadlock.  The code
+uses integer types from <stdint.h> now instead of the old Mach types.
+
+The VM cache policy change has been merged.  The kernel now caches
+unreferenced VM objects unconditionally instead of using a fixed
+limit.
+
+The physical page allocator of the X15 kernel has been integrated, and
+is now used directly by the slab allocator.  This increases the kernel
+heap addressing important scalability issues.
+
+The gsync synchronization mechanism was added, similar to the Linux kernel's
+futexes, to allow efficient and powerful userland synchronization.
+
+Support for profiling kernel code from userland through sampling was added.

+Version 1.6 (2015-10-31)
+
+The code has been updated to work with newer versions of the compiler,
+and numerous bugs have been fixed throughout the code.
+
+The lock debugging infrastructure has been revived and improved, and
+many locking issues have been fixed.
+
+The IPC tables and the hash table mapping objects to IPC entries have
+been replaced by radix trees.  This addresses a scalability issue, as
+IPC tables required huge amounts of continuous virtual kernel memory.
+
+The kernel now allows non-privileged users to wire a small amount of
+memory.
+
+A bug hindering the eviction of inactive pages by the pageout daemon
+has been identified and fixed.
+
+The kernel now keeps timestamps relative to the system boot time.
+Among other things this fixes bogus uptime readings if the system time
+is altered.
+
+A reference leak in the exception handling mechanism has been
+identified and fixed.
+
+ANSI escape sequences are now handled when using `printf'.  This fixes
+the formatting of messages printed by various Linux drivers.
