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).
12 Various bugs fixed in the Windows build. Mainly to do with capturing
13 and restoring alternate data streams correctly in weird cases, and
14 requesting the correct privileges when opening files. Also added the
15 --noacls options to wimlib-imagex capture, append, and apply.
17 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
18 dynamically loaded, so this may make the library compatible with Windows
19 XP (however, there may still be other problems).
22 Added experimental support for native Windows builds. Binaries can be
23 downloaded from the SourceForge page.
25 --source-list option added to `imagex capture' and `imagex append'.
27 Better support for different character encodings.
30 Storing UNIX file owners, groups, and modes in WIM images is now
31 possible using `imagex capture' with the --unix-data flag.
33 Minor bug fixes and documentation fixes.
36 NTFS capture: Fixed capturing duplicate reparse points.
38 NTFS capture: Capture first unnamed stream if there are more than one
39 (print warning instead of error).
41 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
44 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
47 Update to work with ntfs-3g version 2013.1.13.
50 Fixed truncating file to shorter but non-zero length on read-write
53 Various code cleanups and minor documentation fixes.
56 LZX and XPRESS decompression have received some additional optimizations
57 and should now be even faster. (Although, they were already pretty
58 fast--- much faster than typical I/O speeds.)
60 Fixed a bug introduced in v1.2.1 that would cause a directory tree
61 containing hard links to be captured incorrectly in some cases.
64 By default, unmounting a read-write mounted WIM with 'imagex unmount
65 --commit' will now change the WIM in-place without needing to write the
66 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
69 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
70 for a response from the daemon servicing the mounted WIM. Instead,
71 every second 'imagex unmount' will check if the daemon is still alive,
72 and keep waiting if so, otherwise terminate with an error.
74 'imagex unmount --commit' on a read-write mounted WIM will now print
75 progress information regarding the writing of new or modified streams
76 the WIM, just like when capturing or appending a WIM.
78 A small change has been made to XPRESS compression and it should improve
79 the compression ratio slightly.
81 A change was made that may improve performance slightly when applying a
82 WIM image to a NTFS volume.
84 Microsoft has managed to introduce even more bugs into their software,
85 and now the WIMs for Windows 8 have incorrect (too low) reference counts
86 for some streams. This is unsafe because such streams can be removed
87 when they are in actuality still referenced in the WIM (perhaps by a
88 different image). wimlib will now work around this problem by fixing
89 the stream reference counts. This is only done when wimlib_delete_image() is
90 called ('imagex delete') or when wimlib_mount_image() is called with
91 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
92 requires reading the metadata for all images in the WIM, so this will
93 make these operations noticably slower on WIMs with multiple images.
95 Various other bugfixes.
98 Appending images to a WIM is now be done by default without re-building
99 the whole WIM. Use the --rebuild flag to get the old behavior (which
100 was to re-build the entire WIM when a new image is appended).
102 A new command `imagex optimize' is now available to manually re-build a
103 WIM that has wasted space due to repeated appends.
105 Progress information has been improved, and now arbitrary callback
106 functions can be used to show the progress of a WIM operation.
108 A possible bug with changing the bootable image of a WIM was fixed.
110 Some advisory locking is now done to prevent two processes from
111 modifying a WIM at the same time (but only in some cases). For example,
112 you cannot mount two images from a WIM read-write at the same time.
114 Some functions have been reorganized:
115 * wimlib_mount() renamed to wimlib_mount_image().
116 * wimlib_unmount() renamed to wimlib_unmount_image().
117 * wimlib_overwrite_xml_and_header() removed as
118 wimlib_overwrite() suffices now.
119 * wimlib_apply_image_to_ntfs_volume() removed as
120 wimlib_extract_image() suffices now.
121 * wimlib_add_image_from_ntfs_volume() removed as
122 * wimlib_add_image() suffices now.
124 Previously, the soname of libwim.so has been 0.0.0, despite many
125 interface changes. The soname is now updated to 1.0.0 and will now be
126 updated each release.
129 Resources will now be compressed using multiple threads by default.
130 (This applies to `imagex capture', `imagex append', and `imagex
133 Some performance improvements in mounted WIMs.
135 More progress information is shown when capturing a WIM.
138 Lots of minor fixes, code cleanups, and some documentation updates.
139 Nothing in particular is really noteworthy.
142 LZX and XPRESS compression improvements.
144 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
145 Link Bytes of the WIM.
148 Fixed bug when capturing NTFS file with multiple named data streams.
150 Internally, we are now using inode structures, even though these don't
151 appear literally in the WIM file. This simplifies some of the code
152 (mainly for WIM mounting) and likely fixed a few problems, although it
156 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
160 Enough changes to call it version 1.0.0!
162 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
163 to a NTFS volume, is now supported.
165 Hard links and symbolic links have much improved support. They are
166 supported for WIM capture, WIM application, and mounted WIMs (you can
167 even make them on read-write mounted WIMs).
169 Alternate data streams are now supported on mounted WIMs through an
170 xattr or a Windows-style stream interface. Also they are supported when
171 capturing a WIM from NTFS or applying a WIM to NTFS.
173 Split WIMs are better supported. You may now apply an image directly
174 from a split WIM, mount an image from a split WIM read-only, or export
175 an image from a split WIM.
177 Using a capture configuration file is now supported (but not fully yet).
179 SHA1 message digests are checked in more places, so we can make sure
180 applied and captured data is correct.
182 Man pages have been updated and consolidated.
185 Fixed segfault when unmounting read-only WIM.
188 Support for joining and splitting WIMs.
189 Also, security data is now preserved by default.
192 Can now build with older gcc and system headers, like on CentOS 5.
195 Fixed bug that made it impossible to overwrite files in read-write
199 Write byte-order mark before WIM XML data. (imagex.exe requires this to
