+===============================================================================
+* Bug fix: GPT header CRC was computed from all 512 bytes rather than from 92.
+* Bug fix: Unspecified Expiration Time and Effective Time of ISO volume was
+           represented by 0-bytes rather than ASCII '0' digits.
+* Bug fix: Reserved and unused fields of APM entries were not zeroed.
+* Bug fix: The protective MBR partition for GPT started at block 0 instead of 1.
+* New option bits with el_torito_set_isolinux_options() and
+  iso_write_opts_set_system_area() to control GRUB2 patching of

+           which stem from a previous session.
+* Bug fix: Reading damaged Rock Ridge data could cause SIGSEGV by NULL.

+* Bug fix: Symbol iso_fs_global_id was missing in libisofs.ver.
+* Bug fix: Volume descriptors of Joliet and ISO 9660:1999 beared non-zero
+           Effective Date, involuntarily restricting the early end of

+* Bug fix: File Structure Version field of ISO 9660:1999 Enhanced Volume

+* Bug fix: The separator dot of Joliet names was byte swapped on big-endian
+           machines.

+APM has an adjustable block size. Because the ISO images shall always work
+on optical media, and in order to make room for the header block of an
+additional GPT, only block size 2048 is considered here.
+The role of APM in the boot process is to guide the firmware to a
+HFS+ filesystem.
+
+Block0 of an APM begins at byte 0 of the medium. Thus it collides with MBR and
+other boot sector formats. By lucky coincidence it is possible to compose
+a mock-up of a Block0 which is acceptable to firmware which expects APM,
+and is also harmless x86 machine code with no negative side effects.
+So it is possible to combine APM with an especially prepared MBR.

-An isohybrid MBR directs the booting BIOS to an ISOLINUX boot image which
-is also the target of an El Torito boot catalog entry.
-For that purpose one has to take an MBR template and has to set a few bytes
-to values which sufficiently describe the ISO image and the boot image file.
+GPT is the partition map format of EFI, a successor of PC-BIOS.
+Block size is always 512. GPT consists of a header block at block address 1 and
+a partition table near the start of the medium. This is called the primary GPT.
+There is a backup copy of header and table near the end of the medium.
 
-Words are composed little-endian style.
+GPT is particularly designed to co-exist with MBR. If it is present, then the
+booting firmware may or may not prefer it over the MBR partition table.
+GPT can co-exist with APM if APM block size is at least 1024. In this case,
+the primary partition table will begin after the last APM entry block.

+---------- | ---------- | ----------------------------------------------------
+
+The CRC-32 algorithm can be characterized as follows:
+The generating polynomial has the bit representation 0x104c11db7.
+The seed value for a bit shifting division algorithm is 0x46af6449. It is
+chosen so that the CRC of 0 bytes of input is 0x00000000.
+The least significant bits of input bytes get processed first. I.e. bit0 of
+the last input byte gets mapped to x exp (7 + 32), bit7 of this byte gets
+mapped to x exp (0 + 32).
+The resulting division residue gets bitwise mirrored. E.g. bit0 becomes bit31,
+bit1 becomes bit30, and so on. Further it gets exored with 0xffffffff.
+
+A GUID consists of a 32-bit integer, two 16-bit integers, and an array of
+8 bytes. The integers are to be stored big-endian.
+A globally registered class of GUID are the partition type GUIDs.
+This example uses two of them
+Basic data partition:  a2 a0 d0 eb , e5 b9 , 33 44 , 87 c0 68 b6 b7 26 99 c7
+HFS+ partition      :  00 53 46 48 , 00 00 , aa 11 , aa 11 00 30 65 43 ec ac
+EFI System partition:  28 73 2a c1 , 1f f8 , d2 11 , ba 4b 00 a0 c9 3e c9 3b
+Note that the wikipedia list shows the first 32-bit word and the next two
+16-bit words in little-endia interpretation.
+
+The partition table is an array of entries. Each has a size of 128 bytes.
+A partition table entry looks like:

+Near to the end of the image, after any data blocks which might be of interest
+for the filesystems covered by GPT partitions, there is a backup of partition
+table and header block.
+The header block is supposed to mark the end of the usable medium. But libisofs
+may have the need to add more data.
+The partition table is stored directly before the header block. So it will
+normally not begin at a 2 KiB block start.

+    EFI GPT partition, PreP MBR partition, mountable FAT partition
+
+>>> ? With PC-BIOS MBR x86 Code ?
+
+This storage layout was mainly defined by Vladimir Serbinenko. It relies much
+on the embedded HFS+/FAT filesystem for which he provided the code to libisofs.
+
+Start Blocks (2 KiB):
+     0  System Area
+    16  Volume Descriptors
+  TREE  ISO-RR tree, Joliet tree, other trees and meta data, except HFS+/FAT
+   EFI  EFI boot image partition (optional)
+  PREP  Prep image partition (optional)
+  HFAT  HFS+/FAT metadata (optional)
+  DATA  Data file content (including El Torito boot images)
+  HFSB  HFS superblock backup (if HFS+/FAT metadata)
+  TAIL  Further tails and paddings (optional)
+  GPTB  GPT backup (if GPT in System Area) 
+   END  End of ISO image
+ 
+System Area may contain simultaneously:
+   MBR (x86 boot code must leave room for 8 bytes mock-up of APM Block0)
+   APM
+   GPT
+
+MBR Partitions:
+   0xee from    0 to PREP-1, protective partition, announcing presence of GPT
+   0x41 from PREP to HFAT-1, PreP partition
+   0x0c from HFAT to  END-1, FAT partition, bootable bit on
+   0x00                      Empty partition
+
+GPT Partitions:
+   The primary GPT itself covers the System Area.
+   Basic Data  from   16 to  EFI-1, protects first part of ISO image
+   EFI System  from  EFI to PREP-1, offers EFI image for booting
+   Basic Data  from PREP to HFAT-1, protects PreP partition
+   HFS+        from HFAT to TAIL-1, offers HFS+ for mounting
+   Basic Data  from TAIL to GPTB-1, protects rest of ISO image (if there is)
+
+APM Partitions:
+   The range from end of APM to end of System Area stays unprotected.
+   (The primary GPT might sit there.) 
+   Apple_partition_map from    1 to 3 or 4, covers the APM itself
+   ISO9660_data        from   16 to HFAT-1, covers first part of ISO image
+   Apple_HFS           from HFAT to GPTB-1, offers HFS+ for boot and mount
+   ISO9660_data        from GPTB to  END-1, covers rest of ISO image
+                                            (might be omitted if empty)
+
+El Torito:
+   Boot image for 80x86 PC-BIOS 
+   Boot image for EFI (usually the same file as the partition EFI to PREP-1).
+
+If optional components are not present, then their addresses coincide with
+the address of the next component that is present. E.g. HFAT == DATA if no
+HFS+/FAT filesystem is present.
+If no FAT filesystem is present within HFS+/FAT, then the type of the last
+partition is 0xcd.
+If neither EFI, nor PreP, nor FAT within HFS+/FAT, are present, then there
+is only one partition. It has type 0xee, if GPT is present in the System Area.
+It has type 0xcd and offset 1*512, if no GPT is present.
+
+Involved -as mkisofs options:
+  -hfsplus
+  -fat
+  -efi-boot-part DISKFILE
+  -prep-boot-part DISKFILE

+Name:
+      isofs.hx
+
+Purpose:
+      Records the iso_hfsplus_xinfo_data information as defined in libisofs.h.
+      At image load time, this info shall be converted back into an xinfo
+      attachment for iso_hfsplus_xinfo_func so that it is available for
+      the HFS+ writer when a new ISO 9660 / HFS+ image gets produced.
+
+Format of Value:
+      VERSION_LEN | VERSION | CREATOR | TYPE
+      VERSION_LEN complies to ISO 9660 Format section 7.1.1.
+      The byte string VERSION begins with the most significant byte.
+      VERSION == 0 is the only one that is currently defined. It assures the
+      existence of 4 bytes CREATOR and 4 bytes TYPE.
+      Higher versions will keep these 8 bytes and possibly add new ones. 
+
+Example:
+      { 1, 0, 'Y', 'Y', 'D', 'N', 'T', 'E', 'X', 'T' }

-    In general, burn_source objects can be freed as soon as they are attached
-    to track objects. The track objects will keep them alive and dispose them
