1 Only the most important changes more recent than version 0.6 are noted here.
4 On Windows, paths given to wimlib-imagex are now treated case
7 Improved behavior regarding invalid filenames; in particular, on
8 Windows, wimlib-imagex will, when extracting, now omit (with an option
9 to override this default) filenames differing only in case, or filenames
10 containing characters not valid on Windows.
12 On Windows, wimlib now supports capturing and extracting long paths
13 (longer than the so-called MAX_PATH).
15 On Windows, `wimlib-imagex update' now acquires proper privileges when
16 running as an Administrator.
18 `wimlib-imagex update' will now complain if no image is specified when
19 trying to update a multi-image WIM.
21 `wimlib-imagex update' now supports specifying a single update command
22 directly on the command line using the --command option.
24 wimlib-imagex will now choose different units for progress messages,
25 depending on the amount of data that needs to be processed.
27 Fixed a couple issues with using wimlib-imagex on UDF filesystems.
30 Added new "extract" and "update" subcommands to wimlib-imagex, along
31 with associated APIs in the library. These commands are intended mainly
32 for Windows use but can be used on UNIX as well.
34 Many documentation improvements.
36 Fixed a bug in the Windows build where relative symbolic links were not
37 captured in reparse-point fixup mode.
39 Fixed a bug in the Windows build where file handles were left open to
40 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
42 Fixed a bug in the Windows build of wimlib-imagex where globbing
43 split-WIM parts could cause the program to crash.
45 Fixed a bug where the creation time of WIM images would be shown instead
46 of the last modification time.
48 With the Windows build it is now possible to restore a WIM containing
49 symbolic links as a non-Administrator; however you will receive warnings
50 about not being able to extract the symbolic links.
53 Capturing a WIM image should now be significantly faster in most cases
54 due to improved use of the operating system's cache and avoiding reading
55 files twice whenever possible.
57 The Windows build should now work on Windows XP.
59 The Windows build now supports capturing and restoring hidden,
60 compressed, sparse, and encrypted files.
62 The Windows build now supports capturing and applying WIM images from
63 filesystems other than NTFS (with some reduced functionality).
65 The Windows build now extracts short names correctly.
67 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
68 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
69 capture' and `wimlib-imagex apply'.
71 The performance of splitting and joining WIMs should be slightly
74 The LZX and XPRESS compression and decompression functions are now
75 exported from the library.
78 Improvements and bugfixes for the Windows build.
80 Added --strict-acls options.
82 Fixed the way that wimlib determines the order of images in the WIM.
85 Since wimlib can now be used on Windows, wimlib's implementation of
86 ImageX has been renamed to wimlib-imagex to avoid confusion with
87 Microsoft's implementation of ImageX, which would have the same file
88 name ("imagex.exe"). If you really don't like this you can pass the
89 --with-imagex-progname option to `configure' to choose a different name,
90 or even simply rename the binary yourself (but the former way will
91 configure the man pages to use the chosen name).
93 Various bugs fixed in the Windows build. Mainly to do with capturing
94 and restoring alternate data streams correctly in weird cases, and
95 requesting the correct privileges when opening files. Also added the
96 --noacls options to wimlib-imagex capture, append, and apply.
98 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
99 dynamically loaded, so this may make the library compatible with Windows
100 XP (however, there may still be other problems).
103 Added experimental support for native Windows builds. Binaries can be
104 downloaded from the SourceForge page.
106 --source-list option added to `imagex capture' and `imagex append'.
108 Better support for different character encodings.
111 Storing UNIX file owners, groups, and modes in WIM images is now
112 possible using `imagex capture' with the --unix-data flag.
114 Minor bug fixes and documentation fixes.
117 NTFS capture: Fixed capturing duplicate reparse points.
119 NTFS capture: Capture first unnamed stream if there are more than one
120 (print warning instead of error).
122 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
125 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
128 Update to work with ntfs-3g version 2013.1.13.
131 Fixed truncating file to shorter but non-zero length on read-write
134 Various code cleanups and minor documentation fixes.
137 LZX and XPRESS decompression have received some additional optimizations
138 and should now be even faster. (Although, they were already pretty
139 fast--- much faster than typical I/O speeds.)
141 Fixed a bug introduced in v1.2.1 that would cause a directory tree
142 containing hard links to be captured incorrectly in some cases.
145 By default, unmounting a read-write mounted WIM with 'imagex unmount
146 --commit' will now change the WIM in-place without needing to write the
147 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
150 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
151 for a response from the daemon servicing the mounted WIM. Instead,
152 every second 'imagex unmount' will check if the daemon is still alive,
153 and keep waiting if so, otherwise terminate with an error.
155 'imagex unmount --commit' on a read-write mounted WIM will now print
156 progress information regarding the writing of new or modified streams
157 the WIM, just like when capturing or appending a WIM.
159 A small change has been made to XPRESS compression and it should improve
160 the compression ratio slightly.
162 A change was made that may improve performance slightly when applying a
163 WIM image to a NTFS volume.
165 Microsoft has managed to introduce even more bugs into their software,
166 and now the WIMs for Windows 8 have incorrect (too low) reference counts
167 for some streams. This is unsafe because such streams can be removed
168 when they are in actuality still referenced in the WIM (perhaps by a
169 different image). wimlib will now work around this problem by fixing
170 the stream reference counts. This is only done when wimlib_delete_image() is
171 called ('imagex delete') or when wimlib_mount_image() is called with
172 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
173 requires reading the metadata for all images in the WIM, so this will
174 make these operations noticably slower on WIMs with multiple images.
176 Various other bugfixes.
179 Appending images to a WIM is now be done by default without re-building
180 the whole WIM. Use the --rebuild flag to get the old behavior (which
181 was to re-build the entire WIM when a new image is appended).
183 A new command `imagex optimize' is now available to manually re-build a
184 WIM that has wasted space due to repeated appends.
186 Progress information has been improved, and now arbitrary callback
187 functions can be used to show the progress of a WIM operation.
189 A possible bug with changing the bootable image of a WIM was fixed.
191 Some advisory locking is now done to prevent two processes from
192 modifying a WIM at the same time (but only in some cases). For example,
193 you cannot mount two images from a WIM read-write at the same time.
195 Some functions have been reorganized:
196 * wimlib_mount() renamed to wimlib_mount_image().
197 * wimlib_unmount() renamed to wimlib_unmount_image().
198 * wimlib_overwrite_xml_and_header() removed as
199 wimlib_overwrite() suffices now.
200 * wimlib_apply_image_to_ntfs_volume() removed as
201 wimlib_extract_image() suffices now.
202 * wimlib_add_image_from_ntfs_volume() removed as
203 * wimlib_add_image() suffices now.
205 Previously, the soname of libwim.so has been 0.0.0, despite many
206 interface changes. The soname is now updated to 1.0.0 and will now be
207 updated each release.
210 Resources will now be compressed using multiple threads by default.
211 (This applies to `imagex capture', `imagex append', and `imagex
214 Some performance improvements in mounted WIMs.
216 More progress information is shown when capturing a WIM.
219 Lots of minor fixes, code cleanups, and some documentation updates.
220 Nothing in particular is really noteworthy.
223 LZX and XPRESS compression improvements.
225 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
226 Link Bytes of the WIM.
229 Fixed bug when capturing NTFS file with multiple named data streams.
231 Internally, we are now using inode structures, even though these don't
232 appear literally in the WIM file. This simplifies some of the code
233 (mainly for WIM mounting) and likely fixed a few problems, although it
237 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
241 Enough changes to call it version 1.0.0!
243 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
244 to a NTFS volume, is now supported.
246 Hard links and symbolic links have much improved support. They are
247 supported for WIM capture, WIM application, and mounted WIMs (you can
248 even make them on read-write mounted WIMs).
250 Alternate data streams are now supported on mounted WIMs through an
251 xattr or a Windows-style stream interface. Also they are supported when
252 capturing a WIM from NTFS or applying a WIM to NTFS.
254 Split WIMs are better supported. You may now apply an image directly
255 from a split WIM, mount an image from a split WIM read-only, or export
256 an image from a split WIM.
258 Using a capture configuration file is now supported (but not fully yet).
260 SHA1 message digests are checked in more places, so we can make sure
261 applied and captured data is correct.
263 Man pages have been updated and consolidated.
266 Fixed segfault when unmounting read-only WIM.
269 Support for joining and splitting WIMs.
270 Also, security data is now preserved by default.
273 Can now build with older gcc and system headers, like on CentOS 5.
276 Fixed bug that made it impossible to overwrite files in read-write
280 Write byte-order mark before WIM XML data. (imagex.exe requires this to
