+gfxboot is now loaded via a COM32 module. If you used a line like
+
+gfxboot bootlogo
+
+before in isolinux.cfg or syslinux.cfg, change this to
+
+ui gfxboot bootlogo
+
+and add /usr/share/syslinux/gfxboot.c32 to your boot directory (the one
+where the config file is).
+
+You can also use
+
+ui gfxboot bootlogo message
+
+and remove the
+
+display message
+
+line. The 'message' file will be shown when you leave the gfxboot module (or
+it couldn't be started).
+
+This also means that gfxboot now works with other syslinux variants like
+pxelinux or extlinux.

+commit 0a0e0e41cad93cd16c323cf16f40264a21eedd6c
+Author: H. Peter Anvin <hpa@zytor.com>

+
+    Correct initialization of the cache doubly-linked list
+    
+    The initialization of the cache doubly-linked list had
+    head->next->prev instead of head->prev->next; this entry is supposed
+    to initialize the ->next entry of the last entry in the list (which
+    points back to the head node.)
+    
+    For clarity, consistently use "head" to refer to the head node; the
+    mixing of "head" and "dev->cache_head" needlessly obfuscated the code.
+    
+    The wild pointer reference caused crashes on some systems.
+

+    isohybrid: Use SOURCE_DATE_EPOCH for deterministic results
+    
+    without this patch, iso output contained 4 random bytes
+    at offset 440 for MBR ID
+    
+    See https://reproducible-builds.org/ for why this matters.
+
+
+    isohybrid: Keep entropy for srand
+    
+    without this patch, the seed would often be 0 or 0x70000000
+    
+    The <<2 is added so that pid and ppid do not cancel out each other.

+commit be645d7a9848847388a662f6c0f7571d52ed7a05
+Author: Philippe Coval <philippe.coval@open.eurogiciel.org>
+Date:   Wed Dec 17 16:46:29 2014 -0500
+
+    build: sort sources to build in a more deterministic way
+    
+    It has been observed that binaries contents
+    are depending on the order of linked objects.
+    
+    This order is caused by GNU make's wildcard function
+    and the position of sources on filesystem.
+    
+    This change tries to prevent this kind of randomness.
+    
+    Also consider building using -j1 flag
+    to make it even more reproductible.
+

+
+These functions are defined in sys/sysmacros.h, so add the include to
+main.c.  This is already handled correctly in mountinfo.c.  Otherwise
+we get build failures like:
