+Version 1.7.0-BETA:
Improved compatibility with version 3584 WIM / ESD files.
Performance improvements, including for extraction.
documentation for the new '--wimboot' option to wimcapture and wimapply
for more information.
+ The format of UNIX data has been changed. If you captured any WIMs with
+ the --unix-data option, to upgrade them you'll need to apply them with
+ --unix-data using wimlib v1.6.2, then re-capture them with --unix-data
+ using this version.
+
+ wimlib now understands tagged metadata items, such as object IDs, that
+ can be stored in WIM directory entries.
+
Removed the --hardlink and --symlink options to wimapply, since I don't
think they are too useful and they got in the way of improving the code.
WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
WIMGAPI).
+ - Progress functions, including their prototypes as well as how
+ they are provided to the library, have been changed.
+
- 'struct wimlib_capture_config' has been removed. The library
now takes the path to the configuration file directly. This
affects wimlib_add_image(), wimlib_add_image_multisource(),
