libburnia project is pleased to announce the release of version 1.4.0
of GNU xorriso, a ISO 9660 Rock Ridge filesystem manipulator. Available
on GNU FTP mirrors as

It creates, loads, manipulates and writes ISO 9660 filesystem images with
Rock Ridge extensions. Optionally it supports hard links, ACLs, xattr,
and MD5 checksums.
xorriso can load the management information of existing ISO images and it
writes the session results to optical media or to filesystem objects.
Vice versa xorriso is able to copy file objects from ISO 9660 filesystems
to disk.

A special property of xorriso is that it needs neither an external ISO 9660
formatter program nor an external burn program for CD, DVD or BD but rather
incorporates the libraries of .


* Bug fix: -dev or -indev of medium with non-ISO data caused SIGSEGV by NULL

* Bug fix: A SIGSEGV could happen when loading a faulty ISO filesystem.
           Debian bug 774152. Thanks to Jakub Wilk.

* Bug fix: Rock Ridge Continuation Area could be produced crossing a block
           boundary. This is heavily disliked by the Linux kernel and spoils
           the representation of directories which contain many symbolic links.

* Bug fix: If iso_write_opts_set_hardlinks() enabled automatic inode numbers,
           then they did not get into effect with nodes were zisofs decoder
           filters got attached during the image load process.

* Bug fix: The header indicator of the last El Torito catalog section header
           was set to 0x90 rather than 0x91 if more than one boot image is in
           that section.

* Bug fix: Only 128 bytes of an emerging GPT header block were zeroized.

* Bug fix: -report_system_area did not show GPT partitions of size 0.

* Bug fix: A zero sized GPT partition was marked after the last appended
           GPT partition.

* Improved handling of cylinder alignment if the resulting image size is not
  divisible by 2048. Old behavior was to not align. New is to pad up by a
  few blocks of 512 bytes.

* Increased default weight of El Torito boot catalog to 1 billion.

* New -find action "show_stream_id"

* Optional libisofs interval reader with -append_partition and System Area

* New -boot_image bootspec "appended_part_as=",
  new -as mkisofs option -appended_part_as_gpt

* New -report_system_area formats "cmd" and "as_mkisofs"

- - FreeBSD  : libc, libpthread, libiconv, IDE and SATA drives need atapicam
- - Solaris  : libc, libpthread, libvolmgt
- - NetBSD   : libc, libpthread
- - on other X/Open systems there will be no direct operation of
  CD/DVD/BD drives, but only POSIX i/o which may or may not
  be offered by the system for DVD-RAM, DVD+RW, or BD-RE.

  libreadline + libreadline-development , or libedit
  zlib + zlib-development
  libbz2 + libbz2-development
  on GNU/Linux: libacl + libacl-development
If they were present at compile time, then the optional libraries have to 
be present at runtime, too.
