Only the most important changes more recent than version 0.6 are noted here.
+Version 1.5.1:
+ wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
+ needed to be handled.
+
+ A bug in the interpretation of negative IMAGE indices in the
+ --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
+ `wimlib-imagex append' has been fixed.
+
+ A workaround has been added to successfully apply security descriptors
+ with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
+ 2013.1.13 or earlier.
+
+Version 1.5.0:
+ Added support for "pipable" WIMs. Pipable WIMs allow capturing images
+ to standard output and applying images from standard input, but they are
+ not compatible with Microsoft's software and are not created by default.
+ See the documentation for --pipable flag of `wimlib-imagex capture' for
+ more information.
+
+ To better support incremental backups, added support for declaring an
+ image as a modified form of another image. See the documentation for
+ the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
+ capture'.
+
+ Added supported for "delta" WIMs. See the documentation for the
+ '--delta-from' option of `wimlib-imagex capture'.
+
+ The library support for managing split WIMs has been changed to support
+ other arrangements, such as delta WIMs, and be easier to use. This
+ change is visible in `wimlib-imagex', which also can now accept the
+ '--ref' option multiple times, and also now supports "delta" WIMs as
+ mentioned above.
+
+ wimlib now preserves 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.
+
+ `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.
+
+ Security descriptors are now extracted correctly on Windows.
+
+ Fixed archiving DOS names in NTFS-3g capture mode.
+
+ 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.
+
+ `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
+ than the WAIK itself.
+
+ wimlib_global_init() now, by default, attempts to acquire additional
+ privileges on Windows, so library clients need not do this.
+
+ This update bumps the shared library version number up to 9, since it is
+ not binary compatibible 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.
WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
wimlib_open_wim().
+ wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
+ header.
+
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
