1.1.1.6 ! root        1: Version 1.6 (2015-10-31)
        !             2: 
        !             3: The code has been updated to work with newer versions of the compiler,
        !             4: and numerous bugs have been fixed throughout the code.
        !             5: 
        !             6: The lock debugging infrastructure has been revived and improved, and
        !             7: many locking issues have been fixed.
        !             8: 
        !             9: The IPC tables and the hash table mapping objects to IPC entries have
        !            10: been replaced by radix trees.  This addresses a scalability issue, as
        !            11: IPC tables required huge amounts of continuous virtual kernel memory.
        !            12: 
        !            13: The kernel now allows non-privileged users to wire a small amount of
        !            14: memory.
        !            15: 
        !            16: A bug hindering the eviction of inactive pages by the pageout daemon
        !            17: has been identified and fixed.
        !            18: 
        !            19: The kernel now keeps timestamps relative to the system boot time.
        !            20: Among other things this fixes bogus uptime readings if the system time
        !            21: is altered.
        !            22: 
        !            23: A reference leak in the exception handling mechanism has been
        !            24: identified and fixed.
        !            25: 
        !            26: ANSI escape sequences are now handled when using `printf'.  This fixes
        !            27: the formatting of messages printed by various Linux drivers.
        !            28: 
1.1.1.5   root       29: Version 1.5 (2015-04-10)
                     30: 
                     31: Numerous cleanups and stylistic fixes of the code base.  Several
                     32: problems have been identified using static analysis tools and
                     33: subsequently been fixed.
                     34: 
                     35: A protected payload can now be associated with capabilities.  This
                     36: payload is attached by the kernel to delivered messages and can be
                     37: used to speed up the object lookup in the receiving task.
                     38: 
                     39: The kernel debugger can now parse ELF symbol tables, can be invoked
                     40: over serial lines, gained two new commands and has received usability
                     41: improvements.
                     42: 
                     43: The vm pageout policy has been tuned to accommodate modern hardware.
                     44: 
                     45: The kernel gained partial ACPI support on x86, enough to power down
                     46: the system.
                     47:

                     51: stability fixes, a Xen port for 32-bit x86 including basic support for Physical
                     52: Address Extension (PAE), an initial AHCI driver (SATA hard disks), a new SLAB
                     53: memory allocator to replace the previous zone allocator, support for memory
                     54: object proxies, access restrictions for x86 I/O ports, support for some PCMCIA
                     55: devices based on the pcmcia-cs package.

                     60: module names with the same syntax as the Hurd's `serverboot' program.
                     61: That is, instead of telling GRUB "module /boot/serverboot", you can give
                     62: GRUB a series of command like "module /hurd/ext2fs ${...}" where the
                     63: syntax after "module" is the same as in boot scripts for Hurd's `serverboot'.
