1 Only the most important changes more recent than version 0.6 are noted here.
4 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
7 A bug in the interpretation of negative IMAGE indices in the
8 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
9 `wimlib-imagex append' has been fixed.
11 A workaround has been added to successfully apply security descriptors
12 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
16 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
17 to standard output and applying images from standard input, but they are
18 not compatible with Microsoft's software and are not created by default.
19 See the documentation for --pipable flag of `wimlib-imagex capture' for
22 To better support incremental backups, added support for declaring an
23 image as a modified form of another image. See the documentation for
24 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
27 Added supported for "delta" WIMs. See the documentation for the
28 '--delta-from' option of `wimlib-imagex capture'.
30 The library support for managing split WIMs has been changed to support
31 other arrangements, such as delta WIMs, and be easier to use. This
32 change is visible in `wimlib-imagex', which also can now accept the
33 '--ref' option multiple times, and also now supports "delta" WIMs as
36 wimlib now preserves WIM integrity tables by default, even if
37 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
38 behavior of `wimlib-imagex' whenever the WIM being operated on contains
39 an integrity table and the '--check' option is not specified.
41 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
42 (when --compress is not specified). This provides the best compression
43 ratio by default, which is usually what is desired, at a cost of some
46 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
47 is the command as in `wimlib-imagex COMMAND'; for example, it can be
48 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
49 appropriate hard links are created in UNIX installations of
50 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
51 batch files that emulate this behavior are generated.
53 Security descriptors are now extracted correctly on Windows.
55 Fixed archiving DOS names in NTFS-3g capture mode.
57 The extraction code has been rewritten and it will now be easier to
58 support new features on all supported backends (currently Win32, UNIX,
59 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
60 now supported on all backends, not just UNIX.
62 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
65 wimlib_global_init() now, by default, attempts to acquire additional
66 privileges on Windows, so library clients need not do this.
68 This update bumps the shared library version number up to 9, since it is
69 not binary compatibible with previous releases.
72 Fixed bug in `wimlib-imagex export' that made it impossible to export an
73 image from a WIM that is readonly at the filesystem level.
75 Return error code rather than segfaulting when trying to list files from
76 a non-first part of a split WIM.
78 Joining a WIM will now preserve the RP_FIX and READONLY flags.
81 On Windows, paths given to wimlib-imagex are now treated case
84 Improved behavior regarding invalid filenames; in particular, on
85 Windows, wimlib-imagex will, when extracting, now omit (with an option
86 to override this default) filenames differing only in case, or filenames
87 containing characters not valid on Windows.
89 On Windows, wimlib now supports capturing and extracting long paths
90 (longer than the so-called MAX_PATH).
92 On Windows, `wimlib-imagex update' now acquires proper privileges when
93 running as an Administrator.
95 `wimlib-imagex update' will now complain if no image is specified when
96 trying to update a multi-image WIM.
98 `wimlib-imagex update' now supports specifying a single update command
99 directly on the command line using the --command option.
101 wimlib-imagex will now choose different units for progress messages,
102 depending on the amount of data that needs to be processed.
104 `wimlib-imagex append' will now generate a unique WIM image name if no
105 name is specified and the defaulted name already exists in the WIM.
107 wimlib now allows you to create unnamed WIM images, which can then only
108 be referred to by index.
110 wimlib now allows you to explicitly declare you want write access to a
111 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
114 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
117 Progress callbacks have been added to wimlib's wimlib_update_image()
120 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
121 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
124 NTFS-3g capture now only warns about two conditions previously treated
127 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
130 wimlib now correctly detects and returns an error when reading a WIM
131 image with a cyclic directory structure. (Fun fact: such a WIM will
132 crash Microsoft's software.)
135 Added new "extract" and "update" subcommands to wimlib-imagex, along
136 with associated APIs in the library. These commands are intended mainly
137 for Windows use but can be used on UNIX as well.
139 Many documentation improvements.
141 Fixed a bug in the Windows build where relative symbolic links were not
142 captured in reparse-point fixup mode.
144 Fixed a bug in the Windows build where file handles were left open to
145 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
147 Fixed a bug in the Windows build of wimlib-imagex where globbing
148 split-WIM parts could cause the program to crash.
150 Fixed a bug where the creation time of WIM images would be shown instead
151 of the last modification time.
153 With the Windows build it is now possible to restore a WIM containing
154 symbolic links as a non-Administrator; however you will receive warnings
155 about not being able to extract the symbolic links.
158 Capturing a WIM image should now be significantly faster in most cases
159 due to improved use of the operating system's cache and avoiding reading
160 files twice whenever possible.
162 The Windows build should now work on Windows XP.
164 The Windows build now supports capturing and restoring hidden,
165 compressed, sparse, and encrypted files.
167 The Windows build now supports capturing and applying WIM images from
168 filesystems other than NTFS (with some reduced functionality).
170 The Windows build now extracts short names correctly.
172 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
173 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
174 capture' and `wimlib-imagex apply'.
176 The performance of splitting and joining WIMs should be slightly
179 The LZX and XPRESS compression and decompression functions are now
180 exported from the library.
183 Improvements and bugfixes for the Windows build.
185 Added --strict-acls options.
187 Fixed the way that wimlib determines the order of images in the WIM.
190 Since wimlib can now be used on Windows, wimlib's implementation of
191 ImageX has been renamed to wimlib-imagex to avoid confusion with
192 Microsoft's implementation of ImageX, which would have the same file
193 name ("imagex.exe"). If you really don't like this you can pass the
194 --with-imagex-progname option to `configure' to choose a different name,
195 or even simply rename the binary yourself (but the former way will
196 configure the man pages to use the chosen name).
198 Various bugs fixed in the Windows build. Mainly to do with capturing
199 and restoring alternate data streams correctly in weird cases, and
200 requesting the correct privileges when opening files. Also added the
201 --noacls options to wimlib-imagex capture, append, and apply.
203 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
204 dynamically loaded, so this may make the library compatible with Windows
205 XP (however, there may still be other problems).
208 Added experimental support for native Windows builds. Binaries can be
209 downloaded from the SourceForge page.
211 --source-list option added to `imagex capture' and `imagex append'.
213 Better support for different character encodings.
216 Storing UNIX file owners, groups, and modes in WIM images is now
217 possible using `imagex capture' with the --unix-data flag.
219 Minor bug fixes and documentation fixes.
222 NTFS capture: Fixed capturing duplicate reparse points.
224 NTFS capture: Capture first unnamed stream if there are more than one
225 (print warning instead of error).
227 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
230 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
233 Update to work with ntfs-3g version 2013.1.13.
236 Fixed truncating file to shorter but non-zero length on read-write
239 Various code cleanups and minor documentation fixes.
242 LZX and XPRESS decompression have received some additional optimizations
243 and should now be even faster. (Although, they were already pretty
244 fast--- much faster than typical I/O speeds.)
246 Fixed a bug introduced in v1.2.1 that would cause a directory tree
247 containing hard links to be captured incorrectly in some cases.
250 By default, unmounting a read-write mounted WIM with 'imagex unmount
251 --commit' will now change the WIM in-place without needing to write the
252 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
255 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
256 for a response from the daemon servicing the mounted WIM. Instead,
257 every second 'imagex unmount' will check if the daemon is still alive,
258 and keep waiting if so, otherwise terminate with an error.
260 'imagex unmount --commit' on a read-write mounted WIM will now print
261 progress information regarding the writing of new or modified streams
262 the WIM, just like when capturing or appending a WIM.
264 A small change has been made to XPRESS compression and it should improve
265 the compression ratio slightly.
267 A change was made that may improve performance slightly when applying a
268 WIM image to a NTFS volume.
270 Microsoft has managed to introduce even more bugs into their software,
271 and now the WIMs for Windows 8 have incorrect (too low) reference counts
272 for some streams. This is unsafe because such streams can be removed
273 when they are in actuality still referenced in the WIM (perhaps by a
274 different image). wimlib will now work around this problem by fixing
275 the stream reference counts. This is only done when wimlib_delete_image() is
276 called ('imagex delete') or when wimlib_mount_image() is called with
277 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
278 requires reading the metadata for all images in the WIM, so this will
279 make these operations noticably slower on WIMs with multiple images.
281 Various other bugfixes.
284 Appending images to a WIM is now be done by default without re-building
285 the whole WIM. Use the --rebuild flag to get the old behavior (which
286 was to re-build the entire WIM when a new image is appended).
288 A new command `imagex optimize' is now available to manually re-build a
289 WIM that has wasted space due to repeated appends.
291 Progress information has been improved, and now arbitrary callback
292 functions can be used to show the progress of a WIM operation.
294 A possible bug with changing the bootable image of a WIM was fixed.
296 Some advisory locking is now done to prevent two processes from
297 modifying a WIM at the same time (but only in some cases). For example,
298 you cannot mount two images from a WIM read-write at the same time.
300 Some functions have been reorganized:
301 * wimlib_mount() renamed to wimlib_mount_image().
302 * wimlib_unmount() renamed to wimlib_unmount_image().
303 * wimlib_overwrite_xml_and_header() removed as
304 wimlib_overwrite() suffices now.
305 * wimlib_apply_image_to_ntfs_volume() removed as
306 wimlib_extract_image() suffices now.
307 * wimlib_add_image_from_ntfs_volume() removed as
308 * wimlib_add_image() suffices now.
310 Previously, the soname of libwim.so has been 0.0.0, despite many
311 interface changes. The soname is now updated to 1.0.0 and will now be
312 updated each release.
315 Resources will now be compressed using multiple threads by default.
316 (This applies to `imagex capture', `imagex append', and `imagex
319 Some performance improvements in mounted WIMs.
321 More progress information is shown when capturing a WIM.
324 Lots of minor fixes, code cleanups, and some documentation updates.
325 Nothing in particular is really noteworthy.
328 LZX and XPRESS compression improvements.
330 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
331 Link Bytes of the WIM.
334 Fixed bug when capturing NTFS file with multiple named data streams.
336 Internally, we are now using inode structures, even though these don't
337 appear literally in the WIM file. This simplifies some of the code
338 (mainly for WIM mounting) and likely fixed a few problems, although it
342 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
346 Enough changes to call it version 1.0.0!
348 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
349 to a NTFS volume, is now supported.
351 Hard links and symbolic links have much improved support. They are
352 supported for WIM capture, WIM application, and mounted WIMs (you can
353 even make them on read-write mounted WIMs).
355 Alternate data streams are now supported on mounted WIMs through an
356 xattr or a Windows-style stream interface. Also they are supported when
357 capturing a WIM from NTFS or applying a WIM to NTFS.
359 Split WIMs are better supported. You may now apply an image directly
360 from a split WIM, mount an image from a split WIM read-only, or export
361 an image from a split WIM.
363 Using a capture configuration file is now supported (but not fully yet).
365 SHA1 message digests are checked in more places, so we can make sure
366 applied and captured data is correct.
368 Man pages have been updated and consolidated.
371 Fixed segfault when unmounting read-only WIM.
374 Support for joining and splitting WIMs.
375 Also, security data is now preserved by default.
378 Can now build with older gcc and system headers, like on CentOS 5.
381 Fixed bug that made it impossible to overwrite files in read-write
385 Write byte-order mark before WIM XML data. (imagex.exe requires this to
