1 Only the most important changes more recent than version 0.6 are noted here.
4 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
7 Update to work with ntfs-3g version 2013.1.13.
10 Fixed truncating file to shorter but non-zero length on read-write
13 Various code cleanups and minor documentation fixes.
16 LZX and XPRESS decompression have received some additional optimizations
17 and should now be even faster. (Although, they were already pretty
18 fast--- much faster than typical I/O speeds.)
20 Fixed a bug introduced in v1.2.1 that would cause a directory tree
21 containing hard links to be captured incorrectly in some cases.
24 By default, unmounting a read-write mounted WIM with 'imagex unmount
25 --commit' will now change the WIM in-place without needing to write the
26 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
29 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
30 for a response from the daemon servicing the mounted WIM. Instead,
31 every second 'imagex unmount' will check if the daemon is still alive,
32 and keep waiting if so, otherwise terminate with an error.
34 'imagex unmount --commit' on a read-write mounted WIM will now print
35 progress information regarding the writing of new or modified streams
36 the WIM, just like when capturing or appending a WIM.
38 A small change has been made to XPRESS compression and it should improve
39 the compression ratio slightly.
41 A change was made that may improve performance slightly when applying a
42 WIM image to a NTFS volume.
44 Microsoft has managed to introduce even more bugs into their software,
45 and now the WIMs for Windows 8 have incorrect (too low) reference counts
46 for some streams. This is unsafe because such streams can be removed
47 when they are in actuality still referenced in the WIM (perhaps by a
48 different image). wimlib will now work around this problem by fixing
49 the stream reference counts. This is only done when wimlib_delete_image() is
50 called ('imagex delete') or when wimlib_mount_image() is called with
51 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
52 requires reading the metadata for all images in the WIM, so this will
53 make these operations noticably slower on WIMs with multiple images.
55 Various other bugfixes.
58 Appending images to a WIM is now be done by default without re-building
59 the whole WIM. Use the --rebuild flag to get the old behavior (which
60 was to re-build the entire WIM when a new image is appended).
62 A new command `imagex optimize' is now available to manually re-build a
63 WIM that has wasted space due to repeated appends.
65 Progress information has been improved, and now arbitrary callback
66 functions can be used to show the progress of a WIM operation.
68 A possible bug with changing the bootable image of a WIM was fixed.
70 Some advisory locking is now done to prevent two processes from
71 modifying a WIM at the same time (but only in some cases). For example,
72 you cannot mount two images from a WIM read-write at the same time.
74 Some functions have been reorganized:
75 * wimlib_mount() renamed to wimlib_mount_image().
76 * wimlib_unmount() renamed to wimlib_unmount_image().
77 * wimlib_overwrite_xml_and_header() removed as
78 wimlib_overwrite() suffices now.
79 * wimlib_apply_image_to_ntfs_volume() removed as
80 wimlib_extract_image() suffices now.
81 * wimlib_add_image_from_ntfs_volume() removed as
82 * wimlib_add_image() suffices now.
84 Previously, the soname of libwim.so has been 0.0.0, despite many
85 interface changes. The soname is now updated to 1.0.0 and will now be
89 Resources will now be compressed using multiple threads by default.
90 (This applies to `imagex capture', `imagex append', and `imagex
93 Some performance improvements in mounted WIMs.
95 More progress information is shown when capturing a WIM.
98 Lots of minor fixes, code cleanups, and some documentation updates.
99 Nothing in particular is really noteworthy.
102 LZX and XPRESS compression improvements.
104 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
105 Link Bytes of the WIM.
108 Fixed bug when capturing NTFS file with multiple named data streams.
110 Internally, we are now using inode structures, even though these don't
111 appear literally in the WIM file. This simplifies some of the code
112 (mainly for WIM mounting) and likely fixed a few problems, although it
116 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
120 Enough changes to call it version 1.0.0!
122 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
123 to a NTFS volume, is now supported.
125 Hard links and symbolic links have much improved support. They are
126 supported for WIM capture, WIM application, and mounted WIMs (you can
127 even make them on read-write mounted WIMs).
129 Alternate data streams are now supported on mounted WIMs through an
130 xattr or a Windows-style stream interface. Also they are supported when
131 capturing a WIM from NTFS or applying a WIM to NTFS.
133 Split WIMs are better supported. You may now apply an image directly
134 from a split WIM, mount an image from a split WIM read-only, or export
135 an image from a split WIM.
137 Using a capture configuration file is now supported (but not fully yet).
139 SHA1 message digests are checked in more places, so we can make sure
140 applied and captured data is correct.
142 Man pages have been updated and consolidated.
145 Fixed segfault when unmounting read-only WIM.
148 Support for joining and splitting WIMs.
149 Also, security data is now preserved by default.
152 Can now build with older gcc and system headers, like on CentOS 5.
155 Fixed bug that made it impossible to overwrite files in read-write
159 Write byte-order mark before WIM XML data. (imagex.exe requires this to
