+- update to 1.5.6:
+  * Bug fix: iso_write_opts_set_part_like_isohybrid() did not
+    cause a MBR partition table if the partitions are data files
+    in the ISO rather than appended
+  * Bug fix: The lseek methods of IsoFileSource for local
+    filesystem and loaded ISO returned libisofs error codes as
+    positive off_t numbers
+  * Bug fix: Freshly cloned data files from imported image were
+    not marked as imported.
+  * Bug fix: Size of further CE area was calculated wrong if its
+    CE entry ended exactly at a block boundary
+  * New iso_write_opts_set_system_area() option bits 16:
+    GPT "Legacy BIOS bootable" and 17: GPT writable
+  * New API calls iso_assess_written_features(),
+    iso_read_image_feature_named(), iso_read_image_features_text()
+  * Allowed lseekable device files with
+    iso_tree_add_new_cut_out_node().
+  * Proof-of-concept by Ivan Shmakov.
+  * New API call iso_write_opts_set_max_ce_entries()
