@ -2,6 +2,11 @@ bzr branch lp:libisofs/for-libisoburn (to become libisofs-1.3.0.tar.gz)
===============================================================================
* 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.
* New option bits with el_torito_set_isolinux_options() and
iso_write_opts_set_system_area() to control GRUB2 patching of
boot image and MBR.
* New API calls iso_image_set_sparc_core() and iso_image_get_sparc_core().
