1 Only the most important changes more recent than version 0.6 are noted here.
4 Added support for "pipable" WIMs. This support allows capturing images
5 to standard output or applying images from standard input, but they are
6 not compatible with Microsoft's software and are not created by default.
7 See documentation for --pipable flag of `wimlib-imagex capture' for more
8 information. Two new functions have been added to the library to fully
9 support this: wimlib_write_to_fd() and wimlib_extract_image_from_pipe().
11 wimlib now preserve WIM integrity tables by default, even if
12 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
13 behavior of `wimlib-imagex' whenever the WIM being operated on contains
14 an integrity table and the '--check' option is not specified.
16 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
17 (when --compress is not specified). This provides the best compression
18 ratio by default, which is usually what is desired, at a cost of some
21 Security descriptors are now extracted correctly on Windows.
23 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
26 The test suite no longer fails when run in a locale where the decimal
27 separator is not a period.
29 WIMLIB_PROGRESS_MSG_EXTRACT_DENTRY has been removed and
30 WIMLIB_EXTRACT_FLAG_VERBOSE re-reserved for future use.
32 The extraction code has been rewritten and it will now be easier to
33 support new features on all supported backends (currently Win32, UNIX,
34 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
35 now supported on all backends, not just UNIX.
37 A few changes were made to the error codes returned by library routines.
40 Fixed bug in `wimlib-imagex export' that made it impossible to export an
41 image from a WIM that is readonly at the filesystem level.
43 Return error code rather than segfaulting when trying to list files from
44 a non-first part of a split WIM.
46 Joining a WIM will now preserve the RP_FIX and READONLY flags.
49 On Windows, paths given to wimlib-imagex are now treated case
52 Improved behavior regarding invalid filenames; in particular, on
53 Windows, wimlib-imagex will, when extracting, now omit (with an option
54 to override this default) filenames differing only in case, or filenames
55 containing characters not valid on Windows.
57 On Windows, wimlib now supports capturing and extracting long paths
58 (longer than the so-called MAX_PATH).
60 On Windows, `wimlib-imagex update' now acquires proper privileges when
61 running as an Administrator.
63 `wimlib-imagex update' will now complain if no image is specified when
64 trying to update a multi-image WIM.
66 `wimlib-imagex update' now supports specifying a single update command
67 directly on the command line using the --command option.
69 wimlib-imagex will now choose different units for progress messages,
70 depending on the amount of data that needs to be processed.
72 `wimlib-imagex append' will now generate a unique WIM image name if no
73 name is specified and the defaulted name already exists in the WIM.
75 wimlib now allows you to create unnamed WIM images, which can then only
76 be referred to by index.
78 wimlib now allows you to explicitly declare you want write access to a
79 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
82 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
85 Progress callbacks have been added to wimlib's wimlib_update_image()
88 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
89 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
92 NTFS-3g capture now only warns about two conditions previously treated
95 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
98 wimlib now correctly detects and returns an error when reading a WIM
99 image with a cyclic directory structure. (Fun fact: such a WIM will
100 crash Microsoft's software.)
103 Added new "extract" and "update" subcommands to wimlib-imagex, along
104 with associated APIs in the library. These commands are intended mainly
105 for Windows use but can be used on UNIX as well.
107 Many documentation improvements.
109 Fixed a bug in the Windows build where relative symbolic links were not
110 captured in reparse-point fixup mode.
112 Fixed a bug in the Windows build where file handles were left open to
113 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
115 Fixed a bug in the Windows build of wimlib-imagex where globbing
116 split-WIM parts could cause the program to crash.
118 Fixed a bug where the creation time of WIM images would be shown instead
119 of the last modification time.
121 With the Windows build it is now possible to restore a WIM containing
122 symbolic links as a non-Administrator; however you will receive warnings
123 about not being able to extract the symbolic links.
126 Capturing a WIM image should now be significantly faster in most cases
127 due to improved use of the operating system's cache and avoiding reading
128 files twice whenever possible.
130 The Windows build should now work on Windows XP.
132 The Windows build now supports capturing and restoring hidden,
133 compressed, sparse, and encrypted files.
135 The Windows build now supports capturing and applying WIM images from
136 filesystems other than NTFS (with some reduced functionality).
138 The Windows build now extracts short names correctly.
140 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
141 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
142 capture' and `wimlib-imagex apply'.
144 The performance of splitting and joining WIMs should be slightly
147 The LZX and XPRESS compression and decompression functions are now
148 exported from the library.
151 Improvements and bugfixes for the Windows build.
153 Added --strict-acls options.
155 Fixed the way that wimlib determines the order of images in the WIM.
158 Since wimlib can now be used on Windows, wimlib's implementation of
159 ImageX has been renamed to wimlib-imagex to avoid confusion with
160 Microsoft's implementation of ImageX, which would have the same file
161 name ("imagex.exe"). If you really don't like this you can pass the
162 --with-imagex-progname option to `configure' to choose a different name,
163 or even simply rename the binary yourself (but the former way will
164 configure the man pages to use the chosen name).
166 Various bugs fixed in the Windows build. Mainly to do with capturing
167 and restoring alternate data streams correctly in weird cases, and
168 requesting the correct privileges when opening files. Also added the
169 --noacls options to wimlib-imagex capture, append, and apply.
171 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
172 dynamically loaded, so this may make the library compatible with Windows
173 XP (however, there may still be other problems).
176 Added experimental support for native Windows builds. Binaries can be
177 downloaded from the SourceForge page.
179 --source-list option added to `imagex capture' and `imagex append'.
181 Better support for different character encodings.
184 Storing UNIX file owners, groups, and modes in WIM images is now
185 possible using `imagex capture' with the --unix-data flag.
187 Minor bug fixes and documentation fixes.
190 NTFS capture: Fixed capturing duplicate reparse points.
192 NTFS capture: Capture first unnamed stream if there are more than one
193 (print warning instead of error).
195 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
198 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
201 Update to work with ntfs-3g version 2013.1.13.
204 Fixed truncating file to shorter but non-zero length on read-write
207 Various code cleanups and minor documentation fixes.
210 LZX and XPRESS decompression have received some additional optimizations
211 and should now be even faster. (Although, they were already pretty
212 fast--- much faster than typical I/O speeds.)
214 Fixed a bug introduced in v1.2.1 that would cause a directory tree
215 containing hard links to be captured incorrectly in some cases.
218 By default, unmounting a read-write mounted WIM with 'imagex unmount
219 --commit' will now change the WIM in-place without needing to write the
220 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
223 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
224 for a response from the daemon servicing the mounted WIM. Instead,
225 every second 'imagex unmount' will check if the daemon is still alive,
226 and keep waiting if so, otherwise terminate with an error.
228 'imagex unmount --commit' on a read-write mounted WIM will now print
229 progress information regarding the writing of new or modified streams
230 the WIM, just like when capturing or appending a WIM.
232 A small change has been made to XPRESS compression and it should improve
233 the compression ratio slightly.
235 A change was made that may improve performance slightly when applying a
236 WIM image to a NTFS volume.
238 Microsoft has managed to introduce even more bugs into their software,
239 and now the WIMs for Windows 8 have incorrect (too low) reference counts
240 for some streams. This is unsafe because such streams can be removed
241 when they are in actuality still referenced in the WIM (perhaps by a
242 different image). wimlib will now work around this problem by fixing
243 the stream reference counts. This is only done when wimlib_delete_image() is
244 called ('imagex delete') or when wimlib_mount_image() is called with
245 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
246 requires reading the metadata for all images in the WIM, so this will
247 make these operations noticably slower on WIMs with multiple images.
249 Various other bugfixes.
252 Appending images to a WIM is now be done by default without re-building
253 the whole WIM. Use the --rebuild flag to get the old behavior (which
254 was to re-build the entire WIM when a new image is appended).
256 A new command `imagex optimize' is now available to manually re-build a
257 WIM that has wasted space due to repeated appends.
259 Progress information has been improved, and now arbitrary callback
260 functions can be used to show the progress of a WIM operation.
262 A possible bug with changing the bootable image of a WIM was fixed.
264 Some advisory locking is now done to prevent two processes from
265 modifying a WIM at the same time (but only in some cases). For example,
266 you cannot mount two images from a WIM read-write at the same time.
268 Some functions have been reorganized:
269 * wimlib_mount() renamed to wimlib_mount_image().
270 * wimlib_unmount() renamed to wimlib_unmount_image().
271 * wimlib_overwrite_xml_and_header() removed as
272 wimlib_overwrite() suffices now.
273 * wimlib_apply_image_to_ntfs_volume() removed as
274 wimlib_extract_image() suffices now.
275 * wimlib_add_image_from_ntfs_volume() removed as
276 * wimlib_add_image() suffices now.
278 Previously, the soname of libwim.so has been 0.0.0, despite many
279 interface changes. The soname is now updated to 1.0.0 and will now be
280 updated each release.
283 Resources will now be compressed using multiple threads by default.
284 (This applies to `imagex capture', `imagex append', and `imagex
287 Some performance improvements in mounted WIMs.
289 More progress information is shown when capturing a WIM.
292 Lots of minor fixes, code cleanups, and some documentation updates.
293 Nothing in particular is really noteworthy.
296 LZX and XPRESS compression improvements.
298 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
299 Link Bytes of the WIM.
302 Fixed bug when capturing NTFS file with multiple named data streams.
304 Internally, we are now using inode structures, even though these don't
305 appear literally in the WIM file. This simplifies some of the code
306 (mainly for WIM mounting) and likely fixed a few problems, although it
310 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
314 Enough changes to call it version 1.0.0!
316 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
317 to a NTFS volume, is now supported.
319 Hard links and symbolic links have much improved support. They are
320 supported for WIM capture, WIM application, and mounted WIMs (you can
321 even make them on read-write mounted WIMs).
323 Alternate data streams are now supported on mounted WIMs through an
324 xattr or a Windows-style stream interface. Also they are supported when
325 capturing a WIM from NTFS or applying a WIM to NTFS.
327 Split WIMs are better supported. You may now apply an image directly
328 from a split WIM, mount an image from a split WIM read-only, or export
329 an image from a split WIM.
331 Using a capture configuration file is now supported (but not fully yet).
333 SHA1 message digests are checked in more places, so we can make sure
334 applied and captured data is correct.
336 Man pages have been updated and consolidated.
339 Fixed segfault when unmounting read-only WIM.
342 Support for joining and splitting WIMs.
343 Also, security data is now preserved by default.
346 Can now build with older gcc and system headers, like on CentOS 5.
349 Fixed bug that made it impossible to overwrite files in read-write
353 Write byte-order mark before WIM XML data. (imagex.exe requires this to
