1 Only the most important changes more recent than version 0.6 are noted here.
4 Added experimental support for native Windows builds.
6 --source-list option added to `imagex capture' and `imagex append'.
9 Storing UNIX file owners, groups, and modes in WIM images is now
10 possible using `imagex capture' with the --unix-data flag.
12 Minor bug fixes and documentation fixes.
15 NTFS capture: Fixed capturing duplicate reparse points.
17 NTFS capture: Capture first unnamed stream if there are more than one
18 (print warning instead of error).
20 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
23 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
26 Update to work with ntfs-3g version 2013.1.13.
29 Fixed truncating file to shorter but non-zero length on read-write
32 Various code cleanups and minor documentation fixes.
35 LZX and XPRESS decompression have received some additional optimizations
36 and should now be even faster. (Although, they were already pretty
37 fast--- much faster than typical I/O speeds.)
39 Fixed a bug introduced in v1.2.1 that would cause a directory tree
40 containing hard links to be captured incorrectly in some cases.
43 By default, unmounting a read-write mounted WIM with 'imagex unmount
44 --commit' will now change the WIM in-place without needing to write the
45 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
48 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
49 for a response from the daemon servicing the mounted WIM. Instead,
50 every second 'imagex unmount' will check if the daemon is still alive,
51 and keep waiting if so, otherwise terminate with an error.
53 'imagex unmount --commit' on a read-write mounted WIM will now print
54 progress information regarding the writing of new or modified streams
55 the WIM, just like when capturing or appending a WIM.
57 A small change has been made to XPRESS compression and it should improve
58 the compression ratio slightly.
60 A change was made that may improve performance slightly when applying a
61 WIM image to a NTFS volume.
63 Microsoft has managed to introduce even more bugs into their software,
64 and now the WIMs for Windows 8 have incorrect (too low) reference counts
65 for some streams. This is unsafe because such streams can be removed
66 when they are in actuality still referenced in the WIM (perhaps by a
67 different image). wimlib will now work around this problem by fixing
68 the stream reference counts. This is only done when wimlib_delete_image() is
69 called ('imagex delete') or when wimlib_mount_image() is called with
70 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
71 requires reading the metadata for all images in the WIM, so this will
72 make these operations noticably slower on WIMs with multiple images.
74 Various other bugfixes.
77 Appending images to a WIM is now be done by default without re-building
78 the whole WIM. Use the --rebuild flag to get the old behavior (which
79 was to re-build the entire WIM when a new image is appended).
81 A new command `imagex optimize' is now available to manually re-build a
82 WIM that has wasted space due to repeated appends.
84 Progress information has been improved, and now arbitrary callback
85 functions can be used to show the progress of a WIM operation.
87 A possible bug with changing the bootable image of a WIM was fixed.
89 Some advisory locking is now done to prevent two processes from
90 modifying a WIM at the same time (but only in some cases). For example,
91 you cannot mount two images from a WIM read-write at the same time.
93 Some functions have been reorganized:
94 * wimlib_mount() renamed to wimlib_mount_image().
95 * wimlib_unmount() renamed to wimlib_unmount_image().
96 * wimlib_overwrite_xml_and_header() removed as
97 wimlib_overwrite() suffices now.
98 * wimlib_apply_image_to_ntfs_volume() removed as
99 wimlib_extract_image() suffices now.
100 * wimlib_add_image_from_ntfs_volume() removed as
101 * wimlib_add_image() suffices now.
103 Previously, the soname of libwim.so has been 0.0.0, despite many
104 interface changes. The soname is now updated to 1.0.0 and will now be
105 updated each release.
108 Resources will now be compressed using multiple threads by default.
109 (This applies to `imagex capture', `imagex append', and `imagex
112 Some performance improvements in mounted WIMs.
114 More progress information is shown when capturing a WIM.
117 Lots of minor fixes, code cleanups, and some documentation updates.
118 Nothing in particular is really noteworthy.
121 LZX and XPRESS compression improvements.
123 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
124 Link Bytes of the WIM.
127 Fixed bug when capturing NTFS file with multiple named data streams.
129 Internally, we are now using inode structures, even though these don't
130 appear literally in the WIM file. This simplifies some of the code
131 (mainly for WIM mounting) and likely fixed a few problems, although it
135 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
139 Enough changes to call it version 1.0.0!
141 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
142 to a NTFS volume, is now supported.
144 Hard links and symbolic links have much improved support. They are
145 supported for WIM capture, WIM application, and mounted WIMs (you can
146 even make them on read-write mounted WIMs).
148 Alternate data streams are now supported on mounted WIMs through an
149 xattr or a Windows-style stream interface. Also they are supported when
150 capturing a WIM from NTFS or applying a WIM to NTFS.
152 Split WIMs are better supported. You may now apply an image directly
153 from a split WIM, mount an image from a split WIM read-only, or export
154 an image from a split WIM.
156 Using a capture configuration file is now supported (but not fully yet).
158 SHA1 message digests are checked in more places, so we can make sure
159 applied and captured data is correct.
161 Man pages have been updated and consolidated.
164 Fixed segfault when unmounting read-only WIM.
167 Support for joining and splitting WIMs.
168 Also, security data is now preserved by default.
171 Can now build with older gcc and system headers, like on CentOS 5.
174 Fixed bug that made it impossible to overwrite files in read-write
178 Write byte-order mark before WIM XML data. (imagex.exe requires this to
