-Version 1.8 (2016-10-XX)
+Version 1.8 (2016-12-18)
+
+The memory management system was extensively reworked. A new type for
+physical addresses is now used where appropriate, and the system can
+make use of the high memory segment. Many paging issues have been
+addressed, and as a result the system handles low memory situations
+more gracefully now.
+
+The virtual memory system now uses a red-black tree for allocations,
+and as a result it now supports tasks with tens of thousands of
+mappings.
+
+Debugging and error reporting has been improved. Among other things
+the VM maps are now augmented with names that are used in error
+messages, panics and assertions point to their locations, the lock
+debugging mechanism has been fixed, and the kernel debugger can now
+inspect stack traces reaching into the machine-dependent bits
+implemented in assembler.
+
+As usual, bugs have been fixed throughout the code, including minor
+issues with the gsync synchronization mechanism which is now used for
+the internal locks in the GNU C Library (glibc).
The deprecated external memory management interface has been removed.
+
+The partial ACPI support has been removed.
Version 1.7 (2016-05-18)
@@ -63,7 +86,7 @@ The kernel debugger can now parse ELF symbol tables, can be
invoked
over serial lines, gained two new commands and has received usability
improvements.

+The VM pageout policy has been tuned to accommodate modern hardware.
The kernel gained partial ACPI support on x86, enough to power down
the system.
