1 Only the most important changes more recent than version 0.6 are noted here.
4 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
5 to standard output and applying images from standard input, but they are
6 not compatible with Microsoft's software and are not created by default.
7 See the documentation for --pipable flag of `wimlib-imagex capture' for
8 more information. Two new functions have been added to the library to
9 fully support this: wimlib_write_to_fd() and
10 wimlib_extract_image_from_pipe().
12 wimlib now preserve WIM integrity tables by default, even if
13 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
14 behavior of `wimlib-imagex' whenever the WIM being operated on contains
15 an integrity table and the '--check' option is not specified.
17 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
18 (when --compress is not specified). This provides the best compression
19 ratio by default, which is usually what is desired, at a cost of some
22 For convenience, `wimlib-imagex' now supports being invoked as
23 wimCOMMAND, where COMMAND is the command as in `wimlib-imagex COMMAND';
24 for example, it can be invoked as `wimapply' as an alternative to
25 `wimlib-imagex apply'. The appropriate hard links are created in UNIX
26 installations of `wimlib-imagex', while for the Windows distribution of
27 `wimlib-imagex', batch files that emulate this behavior are generated.
29 `wimlib-imagex' no longer recognizes the 'mount', 'mountrw', and
30 'unmount' commands on Windows, since they didn't work on Windows anyway.
32 Security descriptors are now extracted correctly on Windows.
34 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
37 The test suite no longer fails when run in a locale where the decimal
38 separator is not a period.
40 From the library, WIMLIB_PROGRESS_MSG_EXTRACT_DENTRY has been removed
41 and WIMLIB_EXTRACT_FLAG_VERBOSE re-reserved for future use. Also,
42 WIMLIB_PROGRESS_MSG_JOIN_STREAMS has been removed, but
43 WIMLIB_PROGRESS_MSG_WRITE_STREAMS will be received instead and now
44 provides WIM part numbers.
46 The extraction code has been rewritten and it will now be easier to
47 support new features on all supported backends (currently Win32, UNIX,
48 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
49 now supported on all backends, not just UNIX.
51 The LZX compression and decompression code now compiles correctly on the
52 ARM architecture (where 'char' is unsigned).
54 wimlib_split() progress messages now report the total number of parts
57 Fixed storing DOS names in NTFS-3g capture mode.
59 A few changes were made to the error codes returned by library routines.
61 To make wimlib easier to use on Windows, wimlib_global_init() now
62 automatically attempts to acquire additional privileges on Windows, so
63 library clients need not do this (although they can provide a flag to
64 get the old behavior and manage privileges themselves).
66 This update bumps the shared library version number up to 9, since it
67 doesn't quite maintain binary compatibility with previous releases.
70 Fixed bug in `wimlib-imagex export' that made it impossible to export an
71 image from a WIM that is readonly at the filesystem level.
73 Return error code rather than segfaulting when trying to list files from
74 a non-first part of a split WIM.
76 Joining a WIM will now preserve the RP_FIX and READONLY flags.
79 On Windows, paths given to wimlib-imagex are now treated case
82 Improved behavior regarding invalid filenames; in particular, on
83 Windows, wimlib-imagex will, when extracting, now omit (with an option
84 to override this default) filenames differing only in case, or filenames
85 containing characters not valid on Windows.
87 On Windows, wimlib now supports capturing and extracting long paths
88 (longer than the so-called MAX_PATH).
90 On Windows, `wimlib-imagex update' now acquires proper privileges when
91 running as an Administrator.
93 `wimlib-imagex update' will now complain if no image is specified when
94 trying to update a multi-image WIM.
96 `wimlib-imagex update' now supports specifying a single update command
97 directly on the command line using the --command option.
99 wimlib-imagex will now choose different units for progress messages,
100 depending on the amount of data that needs to be processed.
102 `wimlib-imagex append' will now generate a unique WIM image name if no
103 name is specified and the defaulted name already exists in the WIM.
105 wimlib now allows you to create unnamed WIM images, which can then only
106 be referred to by index.
108 wimlib now allows you to explicitly declare you want write access to a
109 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
112 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
115 Progress callbacks have been added to wimlib's wimlib_update_image()
118 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
119 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
122 NTFS-3g capture now only warns about two conditions previously treated
125 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
128 wimlib now correctly detects and returns an error when reading a WIM
129 image with a cyclic directory structure. (Fun fact: such a WIM will
130 crash Microsoft's software.)
133 Added new "extract" and "update" subcommands to wimlib-imagex, along
134 with associated APIs in the library. These commands are intended mainly
135 for Windows use but can be used on UNIX as well.
137 Many documentation improvements.
139 Fixed a bug in the Windows build where relative symbolic links were not
140 captured in reparse-point fixup mode.
142 Fixed a bug in the Windows build where file handles were left open to
143 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
145 Fixed a bug in the Windows build of wimlib-imagex where globbing
146 split-WIM parts could cause the program to crash.
148 Fixed a bug where the creation time of WIM images would be shown instead
149 of the last modification time.
151 With the Windows build it is now possible to restore a WIM containing
152 symbolic links as a non-Administrator; however you will receive warnings
153 about not being able to extract the symbolic links.
156 Capturing a WIM image should now be significantly faster in most cases
157 due to improved use of the operating system's cache and avoiding reading
158 files twice whenever possible.
160 The Windows build should now work on Windows XP.
162 The Windows build now supports capturing and restoring hidden,
163 compressed, sparse, and encrypted files.
165 The Windows build now supports capturing and applying WIM images from
166 filesystems other than NTFS (with some reduced functionality).
168 The Windows build now extracts short names correctly.
170 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
171 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
172 capture' and `wimlib-imagex apply'.
174 The performance of splitting and joining WIMs should be slightly
177 The LZX and XPRESS compression and decompression functions are now
178 exported from the library.
181 Improvements and bugfixes for the Windows build.
183 Added --strict-acls options.
185 Fixed the way that wimlib determines the order of images in the WIM.
188 Since wimlib can now be used on Windows, wimlib's implementation of
189 ImageX has been renamed to wimlib-imagex to avoid confusion with
190 Microsoft's implementation of ImageX, which would have the same file
191 name ("imagex.exe"). If you really don't like this you can pass the
192 --with-imagex-progname option to `configure' to choose a different name,
193 or even simply rename the binary yourself (but the former way will
194 configure the man pages to use the chosen name).
196 Various bugs fixed in the Windows build. Mainly to do with capturing
197 and restoring alternate data streams correctly in weird cases, and
198 requesting the correct privileges when opening files. Also added the
199 --noacls options to wimlib-imagex capture, append, and apply.
201 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
202 dynamically loaded, so this may make the library compatible with Windows
203 XP (however, there may still be other problems).
206 Added experimental support for native Windows builds. Binaries can be
207 downloaded from the SourceForge page.
209 --source-list option added to `imagex capture' and `imagex append'.
211 Better support for different character encodings.
214 Storing UNIX file owners, groups, and modes in WIM images is now
215 possible using `imagex capture' with the --unix-data flag.
217 Minor bug fixes and documentation fixes.
220 NTFS capture: Fixed capturing duplicate reparse points.
222 NTFS capture: Capture first unnamed stream if there are more than one
223 (print warning instead of error).
225 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
228 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
231 Update to work with ntfs-3g version 2013.1.13.
234 Fixed truncating file to shorter but non-zero length on read-write
237 Various code cleanups and minor documentation fixes.
240 LZX and XPRESS decompression have received some additional optimizations
241 and should now be even faster. (Although, they were already pretty
242 fast--- much faster than typical I/O speeds.)
244 Fixed a bug introduced in v1.2.1 that would cause a directory tree
245 containing hard links to be captured incorrectly in some cases.
248 By default, unmounting a read-write mounted WIM with 'imagex unmount
249 --commit' will now change the WIM in-place without needing to write the
250 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
253 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
254 for a response from the daemon servicing the mounted WIM. Instead,
255 every second 'imagex unmount' will check if the daemon is still alive,
256 and keep waiting if so, otherwise terminate with an error.
258 'imagex unmount --commit' on a read-write mounted WIM will now print
259 progress information regarding the writing of new or modified streams
260 the WIM, just like when capturing or appending a WIM.
262 A small change has been made to XPRESS compression and it should improve
263 the compression ratio slightly.
265 A change was made that may improve performance slightly when applying a
266 WIM image to a NTFS volume.
268 Microsoft has managed to introduce even more bugs into their software,
269 and now the WIMs for Windows 8 have incorrect (too low) reference counts
270 for some streams. This is unsafe because such streams can be removed
271 when they are in actuality still referenced in the WIM (perhaps by a
272 different image). wimlib will now work around this problem by fixing
273 the stream reference counts. This is only done when wimlib_delete_image() is
274 called ('imagex delete') or when wimlib_mount_image() is called with
275 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
276 requires reading the metadata for all images in the WIM, so this will
277 make these operations noticably slower on WIMs with multiple images.
279 Various other bugfixes.
282 Appending images to a WIM is now be done by default without re-building
283 the whole WIM. Use the --rebuild flag to get the old behavior (which
284 was to re-build the entire WIM when a new image is appended).
286 A new command `imagex optimize' is now available to manually re-build a
287 WIM that has wasted space due to repeated appends.
289 Progress information has been improved, and now arbitrary callback
290 functions can be used to show the progress of a WIM operation.
292 A possible bug with changing the bootable image of a WIM was fixed.
294 Some advisory locking is now done to prevent two processes from
295 modifying a WIM at the same time (but only in some cases). For example,
296 you cannot mount two images from a WIM read-write at the same time.
298 Some functions have been reorganized:
299 * wimlib_mount() renamed to wimlib_mount_image().
300 * wimlib_unmount() renamed to wimlib_unmount_image().
301 * wimlib_overwrite_xml_and_header() removed as
302 wimlib_overwrite() suffices now.
303 * wimlib_apply_image_to_ntfs_volume() removed as
304 wimlib_extract_image() suffices now.
305 * wimlib_add_image_from_ntfs_volume() removed as
306 * wimlib_add_image() suffices now.
308 Previously, the soname of libwim.so has been 0.0.0, despite many
309 interface changes. The soname is now updated to 1.0.0 and will now be
310 updated each release.
313 Resources will now be compressed using multiple threads by default.
314 (This applies to `imagex capture', `imagex append', and `imagex
317 Some performance improvements in mounted WIMs.
319 More progress information is shown when capturing a WIM.
322 Lots of minor fixes, code cleanups, and some documentation updates.
323 Nothing in particular is really noteworthy.
326 LZX and XPRESS compression improvements.
328 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
329 Link Bytes of the WIM.
332 Fixed bug when capturing NTFS file with multiple named data streams.
334 Internally, we are now using inode structures, even though these don't
335 appear literally in the WIM file. This simplifies some of the code
336 (mainly for WIM mounting) and likely fixed a few problems, although it
340 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
344 Enough changes to call it version 1.0.0!
346 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
347 to a NTFS volume, is now supported.
349 Hard links and symbolic links have much improved support. They are
350 supported for WIM capture, WIM application, and mounted WIMs (you can
351 even make them on read-write mounted WIMs).
353 Alternate data streams are now supported on mounted WIMs through an
354 xattr or a Windows-style stream interface. Also they are supported when
355 capturing a WIM from NTFS or applying a WIM to NTFS.
357 Split WIMs are better supported. You may now apply an image directly
358 from a split WIM, mount an image from a split WIM read-only, or export
359 an image from a split WIM.
361 Using a capture configuration file is now supported (but not fully yet).
363 SHA1 message digests are checked in more places, so we can make sure
364 applied and captured data is correct.
366 Man pages have been updated and consolidated.
369 Fixed segfault when unmounting read-only WIM.
372 Support for joining and splitting WIMs.
373 Also, security data is now preserved by default.
376 Can now build with older gcc and system headers, like on CentOS 5.
379 Fixed bug that made it impossible to overwrite files in read-write
383 Write byte-order mark before WIM XML data. (imagex.exe requires this to
