1 Only the most important changes more recent than version 0.6 are noted here.
4 Fixed a bug in the Windows build where relative symbolic links were not
5 captured in reparse-point fixup mode.
7 Fixed a bug in the Windows build where file handles were left open to
8 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
10 With the Windows build it is now possible to restore a WIM containing
11 symbolic links as a non-Administrator; however you will receive warnings
12 about not being able to extract the symbolic links.
15 Capturing a WIM image should now be significantly faster in most cases
16 due to improved use of the operating system's cache and avoiding reading
17 files twice whenever possible.
19 The Windows build should now work on Windows XP.
21 The Windows build now supports capturing and restoring hidden,
22 compressed, sparse, and encrypted files.
24 The Windows build now supports capturing and applying WIM images from
25 filesystems other than NTFS (with some reduced functionality).
27 The Windows build now extracts short names correctly.
29 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
30 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
31 capture' and `wimlib-imagex apply'.
33 The performance of splitting and joining WIMs should be slightly
36 The LZX and XPRESS compression and decompression functions are now
37 exported from the library.
40 Improvements and bugfixes for the Windows build.
42 Added --strict-acls options.
44 Fixed the way that wimlib determines the order of images in the WIM.
47 Since wimlib can now be used on Windows, wimlib's implementation of
48 ImageX has been renamed to wimlib-imagex to avoid confusion with
49 Microsoft's implementation of ImageX, which would have the same file
50 name ("imagex.exe"). If you really don't like this you can pass the
51 --with-imagex-progname option to `configure' to choose a different name,
52 or even simply rename the binary yourself (but the former way will
53 configure the man pages to use the chosen name).
55 Various bugs fixed in the Windows build. Mainly to do with capturing
56 and restoring alternate data streams correctly in weird cases, and
57 requesting the correct privileges when opening files. Also added the
58 --noacls options to wimlib-imagex capture, append, and apply.
60 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
61 dynamically loaded, so this may make the library compatible with Windows
62 XP (however, there may still be other problems).
65 Added experimental support for native Windows builds. Binaries can be
66 downloaded from the SourceForge page.
68 --source-list option added to `imagex capture' and `imagex append'.
70 Better support for different character encodings.
73 Storing UNIX file owners, groups, and modes in WIM images is now
74 possible using `imagex capture' with the --unix-data flag.
76 Minor bug fixes and documentation fixes.
79 NTFS capture: Fixed capturing duplicate reparse points.
81 NTFS capture: Capture first unnamed stream if there are more than one
82 (print warning instead of error).
84 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
87 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
90 Update to work with ntfs-3g version 2013.1.13.
93 Fixed truncating file to shorter but non-zero length on read-write
96 Various code cleanups and minor documentation fixes.
99 LZX and XPRESS decompression have received some additional optimizations
100 and should now be even faster. (Although, they were already pretty
101 fast--- much faster than typical I/O speeds.)
103 Fixed a bug introduced in v1.2.1 that would cause a directory tree
104 containing hard links to be captured incorrectly in some cases.
107 By default, unmounting a read-write mounted WIM with 'imagex unmount
108 --commit' will now change the WIM in-place without needing to write the
109 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
112 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
113 for a response from the daemon servicing the mounted WIM. Instead,
114 every second 'imagex unmount' will check if the daemon is still alive,
115 and keep waiting if so, otherwise terminate with an error.
117 'imagex unmount --commit' on a read-write mounted WIM will now print
118 progress information regarding the writing of new or modified streams
119 the WIM, just like when capturing or appending a WIM.
121 A small change has been made to XPRESS compression and it should improve
122 the compression ratio slightly.
124 A change was made that may improve performance slightly when applying a
125 WIM image to a NTFS volume.
127 Microsoft has managed to introduce even more bugs into their software,
128 and now the WIMs for Windows 8 have incorrect (too low) reference counts
129 for some streams. This is unsafe because such streams can be removed
130 when they are in actuality still referenced in the WIM (perhaps by a
131 different image). wimlib will now work around this problem by fixing
132 the stream reference counts. This is only done when wimlib_delete_image() is
133 called ('imagex delete') or when wimlib_mount_image() is called with
134 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
135 requires reading the metadata for all images in the WIM, so this will
136 make these operations noticably slower on WIMs with multiple images.
138 Various other bugfixes.
141 Appending images to a WIM is now be done by default without re-building
142 the whole WIM. Use the --rebuild flag to get the old behavior (which
143 was to re-build the entire WIM when a new image is appended).
145 A new command `imagex optimize' is now available to manually re-build a
146 WIM that has wasted space due to repeated appends.
148 Progress information has been improved, and now arbitrary callback
149 functions can be used to show the progress of a WIM operation.
151 A possible bug with changing the bootable image of a WIM was fixed.
153 Some advisory locking is now done to prevent two processes from
154 modifying a WIM at the same time (but only in some cases). For example,
155 you cannot mount two images from a WIM read-write at the same time.
157 Some functions have been reorganized:
158 * wimlib_mount() renamed to wimlib_mount_image().
159 * wimlib_unmount() renamed to wimlib_unmount_image().
160 * wimlib_overwrite_xml_and_header() removed as
161 wimlib_overwrite() suffices now.
162 * wimlib_apply_image_to_ntfs_volume() removed as
163 wimlib_extract_image() suffices now.
164 * wimlib_add_image_from_ntfs_volume() removed as
165 * wimlib_add_image() suffices now.
167 Previously, the soname of libwim.so has been 0.0.0, despite many
168 interface changes. The soname is now updated to 1.0.0 and will now be
169 updated each release.
172 Resources will now be compressed using multiple threads by default.
173 (This applies to `imagex capture', `imagex append', and `imagex
176 Some performance improvements in mounted WIMs.
178 More progress information is shown when capturing a WIM.
181 Lots of minor fixes, code cleanups, and some documentation updates.
182 Nothing in particular is really noteworthy.
185 LZX and XPRESS compression improvements.
187 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
188 Link Bytes of the WIM.
191 Fixed bug when capturing NTFS file with multiple named data streams.
193 Internally, we are now using inode structures, even though these don't
194 appear literally in the WIM file. This simplifies some of the code
195 (mainly for WIM mounting) and likely fixed a few problems, although it
199 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
203 Enough changes to call it version 1.0.0!
205 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
206 to a NTFS volume, is now supported.
208 Hard links and symbolic links have much improved support. They are
209 supported for WIM capture, WIM application, and mounted WIMs (you can
210 even make them on read-write mounted WIMs).
212 Alternate data streams are now supported on mounted WIMs through an
213 xattr or a Windows-style stream interface. Also they are supported when
214 capturing a WIM from NTFS or applying a WIM to NTFS.
216 Split WIMs are better supported. You may now apply an image directly
217 from a split WIM, mount an image from a split WIM read-only, or export
218 an image from a split WIM.
220 Using a capture configuration file is now supported (but not fully yet).
222 SHA1 message digests are checked in more places, so we can make sure
223 applied and captured data is correct.
225 Man pages have been updated and consolidated.
228 Fixed segfault when unmounting read-only WIM.
231 Support for joining and splitting WIMs.
232 Also, security data is now preserved by default.
235 Can now build with older gcc and system headers, like on CentOS 5.
238 Fixed bug that made it impossible to overwrite files in read-write
242 Write byte-order mark before WIM XML data. (imagex.exe requires this to
