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 `wimlib-imagex append' will now generate a unique WIM image name if no
28 name is specified and the defaulted name already exists in the WIM.
30 wimlib now allows you to create unnamed WIM images, which can then only
31 be referred to by index.
33 wimlib now allows you to explicitly declare you want write access to a
34 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
37 Progress callbacks have been added to wimlib's wimlib_update_image()
40 NTFS-3g capture now only warns about two conditions previously treated
43 Fixed a couple issues with using wimlib-imagex on UDF filesystems.
46 Added new "extract" and "update" subcommands to wimlib-imagex, along
47 with associated APIs in the library. These commands are intended mainly
48 for Windows use but can be used on UNIX as well.
50 Many documentation improvements.
52 Fixed a bug in the Windows build where relative symbolic links were not
53 captured in reparse-point fixup mode.
55 Fixed a bug in the Windows build where file handles were left open to
56 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
58 Fixed a bug in the Windows build of wimlib-imagex where globbing
59 split-WIM parts could cause the program to crash.
61 Fixed a bug where the creation time of WIM images would be shown instead
62 of the last modification time.
64 With the Windows build it is now possible to restore a WIM containing
65 symbolic links as a non-Administrator; however you will receive warnings
66 about not being able to extract the symbolic links.
69 Capturing a WIM image should now be significantly faster in most cases
70 due to improved use of the operating system's cache and avoiding reading
71 files twice whenever possible.
73 The Windows build should now work on Windows XP.
75 The Windows build now supports capturing and restoring hidden,
76 compressed, sparse, and encrypted files.
78 The Windows build now supports capturing and applying WIM images from
79 filesystems other than NTFS (with some reduced functionality).
81 The Windows build now extracts short names correctly.
83 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
84 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
85 capture' and `wimlib-imagex apply'.
87 The performance of splitting and joining WIMs should be slightly
90 The LZX and XPRESS compression and decompression functions are now
91 exported from the library.
94 Improvements and bugfixes for the Windows build.
96 Added --strict-acls options.
98 Fixed the way that wimlib determines the order of images in the WIM.
101 Since wimlib can now be used on Windows, wimlib's implementation of
102 ImageX has been renamed to wimlib-imagex to avoid confusion with
103 Microsoft's implementation of ImageX, which would have the same file
104 name ("imagex.exe"). If you really don't like this you can pass the
105 --with-imagex-progname option to `configure' to choose a different name,
106 or even simply rename the binary yourself (but the former way will
107 configure the man pages to use the chosen name).
109 Various bugs fixed in the Windows build. Mainly to do with capturing
110 and restoring alternate data streams correctly in weird cases, and
111 requesting the correct privileges when opening files. Also added the
112 --noacls options to wimlib-imagex capture, append, and apply.
114 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
115 dynamically loaded, so this may make the library compatible with Windows
116 XP (however, there may still be other problems).
119 Added experimental support for native Windows builds. Binaries can be
120 downloaded from the SourceForge page.
122 --source-list option added to `imagex capture' and `imagex append'.
124 Better support for different character encodings.
127 Storing UNIX file owners, groups, and modes in WIM images is now
128 possible using `imagex capture' with the --unix-data flag.
130 Minor bug fixes and documentation fixes.
133 NTFS capture: Fixed capturing duplicate reparse points.
135 NTFS capture: Capture first unnamed stream if there are more than one
136 (print warning instead of error).
138 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
141 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
144 Update to work with ntfs-3g version 2013.1.13.
147 Fixed truncating file to shorter but non-zero length on read-write
150 Various code cleanups and minor documentation fixes.
153 LZX and XPRESS decompression have received some additional optimizations
154 and should now be even faster. (Although, they were already pretty
155 fast--- much faster than typical I/O speeds.)
157 Fixed a bug introduced in v1.2.1 that would cause a directory tree
158 containing hard links to be captured incorrectly in some cases.
161 By default, unmounting a read-write mounted WIM with 'imagex unmount
162 --commit' will now change the WIM in-place without needing to write the
163 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
166 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
167 for a response from the daemon servicing the mounted WIM. Instead,
168 every second 'imagex unmount' will check if the daemon is still alive,
169 and keep waiting if so, otherwise terminate with an error.
171 'imagex unmount --commit' on a read-write mounted WIM will now print
172 progress information regarding the writing of new or modified streams
173 the WIM, just like when capturing or appending a WIM.
175 A small change has been made to XPRESS compression and it should improve
176 the compression ratio slightly.
178 A change was made that may improve performance slightly when applying a
179 WIM image to a NTFS volume.
181 Microsoft has managed to introduce even more bugs into their software,
182 and now the WIMs for Windows 8 have incorrect (too low) reference counts
183 for some streams. This is unsafe because such streams can be removed
184 when they are in actuality still referenced in the WIM (perhaps by a
185 different image). wimlib will now work around this problem by fixing
186 the stream reference counts. This is only done when wimlib_delete_image() is
187 called ('imagex delete') or when wimlib_mount_image() is called with
188 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
189 requires reading the metadata for all images in the WIM, so this will
190 make these operations noticably slower on WIMs with multiple images.
192 Various other bugfixes.
195 Appending images to a WIM is now be done by default without re-building
196 the whole WIM. Use the --rebuild flag to get the old behavior (which
197 was to re-build the entire WIM when a new image is appended).
199 A new command `imagex optimize' is now available to manually re-build a
200 WIM that has wasted space due to repeated appends.
202 Progress information has been improved, and now arbitrary callback
203 functions can be used to show the progress of a WIM operation.
205 A possible bug with changing the bootable image of a WIM was fixed.
207 Some advisory locking is now done to prevent two processes from
208 modifying a WIM at the same time (but only in some cases). For example,
209 you cannot mount two images from a WIM read-write at the same time.
211 Some functions have been reorganized:
212 * wimlib_mount() renamed to wimlib_mount_image().
213 * wimlib_unmount() renamed to wimlib_unmount_image().
214 * wimlib_overwrite_xml_and_header() removed as
215 wimlib_overwrite() suffices now.
216 * wimlib_apply_image_to_ntfs_volume() removed as
217 wimlib_extract_image() suffices now.
218 * wimlib_add_image_from_ntfs_volume() removed as
219 * wimlib_add_image() suffices now.
221 Previously, the soname of libwim.so has been 0.0.0, despite many
222 interface changes. The soname is now updated to 1.0.0 and will now be
223 updated each release.
226 Resources will now be compressed using multiple threads by default.
227 (This applies to `imagex capture', `imagex append', and `imagex
230 Some performance improvements in mounted WIMs.
232 More progress information is shown when capturing a WIM.
235 Lots of minor fixes, code cleanups, and some documentation updates.
236 Nothing in particular is really noteworthy.
239 LZX and XPRESS compression improvements.
241 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
242 Link Bytes of the WIM.
245 Fixed bug when capturing NTFS file with multiple named data streams.
247 Internally, we are now using inode structures, even though these don't
248 appear literally in the WIM file. This simplifies some of the code
249 (mainly for WIM mounting) and likely fixed a few problems, although it
253 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
257 Enough changes to call it version 1.0.0!
259 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
260 to a NTFS volume, is now supported.
262 Hard links and symbolic links have much improved support. They are
263 supported for WIM capture, WIM application, and mounted WIMs (you can
264 even make them on read-write mounted WIMs).
266 Alternate data streams are now supported on mounted WIMs through an
267 xattr or a Windows-style stream interface. Also they are supported when
268 capturing a WIM from NTFS or applying a WIM to NTFS.
270 Split WIMs are better supported. You may now apply an image directly
271 from a split WIM, mount an image from a split WIM read-only, or export
272 an image from a split WIM.
274 Using a capture configuration file is now supported (but not fully yet).
276 SHA1 message digests are checked in more places, so we can make sure
277 applied and captured data is correct.
279 Man pages have been updated and consolidated.
282 Fixed segfault when unmounting read-only WIM.
285 Support for joining and splitting WIMs.
286 Also, security data is now preserved by default.
289 Can now build with older gcc and system headers, like on CentOS 5.
292 Fixed bug that made it impossible to overwrite files in read-write
296 Write byte-order mark before WIM XML data. (imagex.exe requires this to
