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
10 To better support incremental backups, added support for declaring an
11 image as a modified form of a prior image. See the documentation for
12 the '--delta-from' option of `wimlib-imagex append'.
14 The library support for managing split WIMs has been changed to support
15 other arrangements, such as delta WIMs, and be easier to use. This
16 change is visible in `wimlib-imagex', which also can now accept the
17 '--ref' option multiple times.
19 wimlib now preserves WIM integrity tables by default, even if
20 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
21 behavior of `wimlib-imagex' whenever the WIM being operated on contains
22 an integrity table and the '--check' option is not specified.
24 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
25 (when --compress is not specified). This provides the best compression
26 ratio by default, which is usually what is desired, at a cost of some
29 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
30 is the command as in `wimlib-imagex COMMAND'; for example, it can be
31 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
32 appropriate hard links are created in UNIX installations of
33 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
34 batch files that emulate this behavior are generated.
36 Security descriptors are now extracted correctly on Windows.
38 Fixed archiving DOS names in NTFS-3g capture mode.
40 The extraction code has been rewritten and it will now be easier to
41 support new features on all supported backends (currently Win32, UNIX,
42 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
43 now supported on all backends, not just UNIX.
45 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
48 wimlib_global_init() now, by default, attempts to acquire additional
49 privileges on Windows, so library clients need not do this.
51 This update bumps the shared library version number up to 9, since it is
52 not binary compatibible with previous releases.
55 Fixed bug in `wimlib-imagex export' that made it impossible to export an
56 image from a WIM that is readonly at the filesystem level.
58 Return error code rather than segfaulting when trying to list files from
59 a non-first part of a split WIM.
61 Joining a WIM will now preserve the RP_FIX and READONLY flags.
64 On Windows, paths given to wimlib-imagex are now treated case
67 Improved behavior regarding invalid filenames; in particular, on
68 Windows, wimlib-imagex will, when extracting, now omit (with an option
69 to override this default) filenames differing only in case, or filenames
70 containing characters not valid on Windows.
72 On Windows, wimlib now supports capturing and extracting long paths
73 (longer than the so-called MAX_PATH).
75 On Windows, `wimlib-imagex update' now acquires proper privileges when
76 running as an Administrator.
78 `wimlib-imagex update' will now complain if no image is specified when
79 trying to update a multi-image WIM.
81 `wimlib-imagex update' now supports specifying a single update command
82 directly on the command line using the --command option.
84 wimlib-imagex will now choose different units for progress messages,
85 depending on the amount of data that needs to be processed.
87 `wimlib-imagex append' will now generate a unique WIM image name if no
88 name is specified and the defaulted name already exists in the WIM.
90 wimlib now allows you to create unnamed WIM images, which can then only
91 be referred to by index.
93 wimlib now allows you to explicitly declare you want write access to a
94 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
97 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
100 Progress callbacks have been added to wimlib's wimlib_update_image()
103 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
104 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
107 NTFS-3g capture now only warns about two conditions previously treated
110 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
113 wimlib now correctly detects and returns an error when reading a WIM
114 image with a cyclic directory structure. (Fun fact: such a WIM will
115 crash Microsoft's software.)
118 Added new "extract" and "update" subcommands to wimlib-imagex, along
119 with associated APIs in the library. These commands are intended mainly
120 for Windows use but can be used on UNIX as well.
122 Many documentation improvements.
124 Fixed a bug in the Windows build where relative symbolic links were not
125 captured in reparse-point fixup mode.
127 Fixed a bug in the Windows build where file handles were left open to
128 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
130 Fixed a bug in the Windows build of wimlib-imagex where globbing
131 split-WIM parts could cause the program to crash.
133 Fixed a bug where the creation time of WIM images would be shown instead
134 of the last modification time.
136 With the Windows build it is now possible to restore a WIM containing
137 symbolic links as a non-Administrator; however you will receive warnings
138 about not being able to extract the symbolic links.
141 Capturing a WIM image should now be significantly faster in most cases
142 due to improved use of the operating system's cache and avoiding reading
143 files twice whenever possible.
145 The Windows build should now work on Windows XP.
147 The Windows build now supports capturing and restoring hidden,
148 compressed, sparse, and encrypted files.
150 The Windows build now supports capturing and applying WIM images from
151 filesystems other than NTFS (with some reduced functionality).
153 The Windows build now extracts short names correctly.
155 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
156 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
157 capture' and `wimlib-imagex apply'.
159 The performance of splitting and joining WIMs should be slightly
162 The LZX and XPRESS compression and decompression functions are now
163 exported from the library.
166 Improvements and bugfixes for the Windows build.
168 Added --strict-acls options.
170 Fixed the way that wimlib determines the order of images in the WIM.
173 Since wimlib can now be used on Windows, wimlib's implementation of
174 ImageX has been renamed to wimlib-imagex to avoid confusion with
175 Microsoft's implementation of ImageX, which would have the same file
176 name ("imagex.exe"). If you really don't like this you can pass the
177 --with-imagex-progname option to `configure' to choose a different name,
178 or even simply rename the binary yourself (but the former way will
179 configure the man pages to use the chosen name).
181 Various bugs fixed in the Windows build. Mainly to do with capturing
182 and restoring alternate data streams correctly in weird cases, and
183 requesting the correct privileges when opening files. Also added the
184 --noacls options to wimlib-imagex capture, append, and apply.
186 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
187 dynamically loaded, so this may make the library compatible with Windows
188 XP (however, there may still be other problems).
191 Added experimental support for native Windows builds. Binaries can be
192 downloaded from the SourceForge page.
194 --source-list option added to `imagex capture' and `imagex append'.
196 Better support for different character encodings.
199 Storing UNIX file owners, groups, and modes in WIM images is now
200 possible using `imagex capture' with the --unix-data flag.
202 Minor bug fixes and documentation fixes.
205 NTFS capture: Fixed capturing duplicate reparse points.
207 NTFS capture: Capture first unnamed stream if there are more than one
208 (print warning instead of error).
210 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
213 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
216 Update to work with ntfs-3g version 2013.1.13.
219 Fixed truncating file to shorter but non-zero length on read-write
222 Various code cleanups and minor documentation fixes.
225 LZX and XPRESS decompression have received some additional optimizations
226 and should now be even faster. (Although, they were already pretty
227 fast--- much faster than typical I/O speeds.)
229 Fixed a bug introduced in v1.2.1 that would cause a directory tree
230 containing hard links to be captured incorrectly in some cases.
233 By default, unmounting a read-write mounted WIM with 'imagex unmount
234 --commit' will now change the WIM in-place without needing to write the
235 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
238 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
239 for a response from the daemon servicing the mounted WIM. Instead,
240 every second 'imagex unmount' will check if the daemon is still alive,
241 and keep waiting if so, otherwise terminate with an error.
243 'imagex unmount --commit' on a read-write mounted WIM will now print
244 progress information regarding the writing of new or modified streams
245 the WIM, just like when capturing or appending a WIM.
247 A small change has been made to XPRESS compression and it should improve
248 the compression ratio slightly.
250 A change was made that may improve performance slightly when applying a
251 WIM image to a NTFS volume.
253 Microsoft has managed to introduce even more bugs into their software,
254 and now the WIMs for Windows 8 have incorrect (too low) reference counts
255 for some streams. This is unsafe because such streams can be removed
256 when they are in actuality still referenced in the WIM (perhaps by a
257 different image). wimlib will now work around this problem by fixing
258 the stream reference counts. This is only done when wimlib_delete_image() is
259 called ('imagex delete') or when wimlib_mount_image() is called with
260 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
261 requires reading the metadata for all images in the WIM, so this will
262 make these operations noticably slower on WIMs with multiple images.
264 Various other bugfixes.
267 Appending images to a WIM is now be done by default without re-building
268 the whole WIM. Use the --rebuild flag to get the old behavior (which
269 was to re-build the entire WIM when a new image is appended).
271 A new command `imagex optimize' is now available to manually re-build a
272 WIM that has wasted space due to repeated appends.
274 Progress information has been improved, and now arbitrary callback
275 functions can be used to show the progress of a WIM operation.
277 A possible bug with changing the bootable image of a WIM was fixed.
279 Some advisory locking is now done to prevent two processes from
280 modifying a WIM at the same time (but only in some cases). For example,
281 you cannot mount two images from a WIM read-write at the same time.
283 Some functions have been reorganized:
284 * wimlib_mount() renamed to wimlib_mount_image().
285 * wimlib_unmount() renamed to wimlib_unmount_image().
286 * wimlib_overwrite_xml_and_header() removed as
287 wimlib_overwrite() suffices now.
288 * wimlib_apply_image_to_ntfs_volume() removed as
289 wimlib_extract_image() suffices now.
290 * wimlib_add_image_from_ntfs_volume() removed as
291 * wimlib_add_image() suffices now.
293 Previously, the soname of libwim.so has been 0.0.0, despite many
294 interface changes. The soname is now updated to 1.0.0 and will now be
295 updated each release.
298 Resources will now be compressed using multiple threads by default.
299 (This applies to `imagex capture', `imagex append', and `imagex
302 Some performance improvements in mounted WIMs.
304 More progress information is shown when capturing a WIM.
307 Lots of minor fixes, code cleanups, and some documentation updates.
308 Nothing in particular is really noteworthy.
311 LZX and XPRESS compression improvements.
313 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
314 Link Bytes of the WIM.
317 Fixed bug when capturing NTFS file with multiple named data streams.
319 Internally, we are now using inode structures, even though these don't
320 appear literally in the WIM file. This simplifies some of the code
321 (mainly for WIM mounting) and likely fixed a few problems, although it
325 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
329 Enough changes to call it version 1.0.0!
331 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
332 to a NTFS volume, is now supported.
334 Hard links and symbolic links have much improved support. They are
335 supported for WIM capture, WIM application, and mounted WIMs (you can
336 even make them on read-write mounted WIMs).
338 Alternate data streams are now supported on mounted WIMs through an
339 xattr or a Windows-style stream interface. Also they are supported when
340 capturing a WIM from NTFS or applying a WIM to NTFS.
342 Split WIMs are better supported. You may now apply an image directly
343 from a split WIM, mount an image from a split WIM read-only, or export
344 an image from a split WIM.
346 Using a capture configuration file is now supported (but not fully yet).
348 SHA1 message digests are checked in more places, so we can make sure
349 applied and captured data is correct.
351 Man pages have been updated and consolidated.
354 Fixed segfault when unmounting read-only WIM.
357 Support for joining and splitting WIMs.
358 Also, security data is now preserved by default.
361 Can now build with older gcc and system headers, like on CentOS 5.
364 Fixed bug that made it impossible to overwrite files in read-write
368 Write byte-order mark before WIM XML data. (imagex.exe requires this to
