Only the most important changes more recent than version 0.6 are noted here.
+Version 1.5.0:
+ Added support for "pipable" WIMs. This support allows capturing images
+ to standard output or applying images from standard input, but they are
+ not compatible with Microsoft's software and are not created by default.
+ See documentation for --pipable flag of `wimlib-imagex capture' for more
+ information. Two new functions have been added to the library to fully
+ support this: wimlib_write_to_fd() and wimlib_extract_image_from_pipe().
+
+ wimlib now preserve WIM integrity tables by default, even if
+ WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
+ behavior of `wimlib-imagex' whenever the WIM being operated on contains
+ an integrity table and the '--check' option is not specified.
+
+ `wimlib-imagex capture' now creates LZX-compressed WIMs by default
+ (when --compress is not specified). This provides the best compression
+ ratio by default, which is usually what is desired, at a cost of some
+ speed.
+
+ For convenience, `wimlib-imagex' now supports being invoked as
+ wimCOMMAND, where COMMAND is the command as in `wimlib-imagex COMMAND';
+ for example, it can be invoked as `wimapply' as an alternative to
+ `wimlib-imagex apply'. The appropriate hard links are created in UNIX
+ installations of `wimlib-imagex', while for the Windows distribution of
+ `wimlib-imagex', batch files that emulate this behavior are generated.
+
+ `wimlib-imagex' no longer recognizes the 'mount', 'mountrw', and
+ 'unmount' commands on Windows, since they didn't work on Windows anyway.
+
+ Security descriptors are now extracted correctly on Windows.
+
+ `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
+ than the WAIK itself.
+
+ The test suite no longer fails when run in a locale where the decimal
+ separator is not a period.
+
+ WIMLIB_PROGRESS_MSG_EXTRACT_DENTRY has been removed and
+ WIMLIB_EXTRACT_FLAG_VERBOSE re-reserved for future use.
+
+ The extraction code has been rewritten and it will now be easier to
+ support new features on all supported backends (currently Win32, UNIX,
+ and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
+ now supported on all backends, not just UNIX.
+
+ A few changes were made to the error codes returned by library routines.
+
+ This update bumps the shared library version number up to 9, since it
+ doesn't quite not maintain binary compatibility with previous releases.
+
+Version 1.4.2:
+ Fixed bug in `wimlib-imagex export' that made it impossible to export an
+ image from a WIM that is readonly at the filesystem level.
+
+ Return error code rather than segfaulting when trying to list files from
+ a non-first part of a split WIM.
+
+ Joining a WIM will now preserve the RP_FIX and READONLY flags.
+
Version 1.4.1:
On Windows, paths given to wimlib-imagex are now treated case
insensitively.
Progress callbacks have been added to wimlib's wimlib_update_image()
function.
+ Added wimlib_get_wim_info(), wimlib_set_wim_info(),
+ wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
+ to the library.
+
NTFS-3g capture now only warns about two conditions previously treated
as errors.
- Fixed a couple issues with using wimlib-imagex on UDF filesystems.
+ Fixed a couple issues with using wimlib-imagex on UDF filesystems on
+ Windows.
+
+ wimlib now correctly detects and returns an error when reading a WIM
+ image with a cyclic directory structure. (Fun fact: such a WIM will
+ crash Microsoft's software.)
Version 1.4.0:
Added new "extract" and "update" subcommands to wimlib-imagex, along
