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