1 Only the most important changes more recent than version 0.6 are noted here.
4 Paths given to wimlib-imagex on Windows 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 `wimlib-imagex update' now acquires proper privileges on Windows when
13 running as an Administrator.
15 `wimlib-imagex update' will now complain if no image is specified when
16 trying to update a multi-image WIM.
18 `wimlib-imagex update' now supports specifying a single update command
19 directly on the command line using the --command option.
21 wimlib-imagex will now choose different units for progress messages,
22 depending on the amount of data that needs to be processed.
25 Added new "extract" and "update" subcommands to wimlib-imagex, along
26 with associated APIs in the library. These commands are intended mainly
27 for Windows use but can be used on UNIX as well.
29 Many documentation improvements.
31 Fixed a bug in the Windows build where relative symbolic links were not
32 captured in reparse-point fixup mode.
34 Fixed a bug in the Windows build where file handles were left open to
35 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
37 Fixed a bug in the Windows build of wimlib-imagex where globbing
38 split-WIM parts could cause the program to crash.
40 Fixed a bug where the creation time of WIM images would be shown instead
41 of the last modification time.
43 With the Windows build it is now possible to restore a WIM containing
44 symbolic links as a non-Administrator; however you will receive warnings
45 about not being able to extract the symbolic links.
48 Capturing a WIM image should now be significantly faster in most cases
49 due to improved use of the operating system's cache and avoiding reading
50 files twice whenever possible.
52 The Windows build should now work on Windows XP.
54 The Windows build now supports capturing and restoring hidden,
55 compressed, sparse, and encrypted files.
57 The Windows build now supports capturing and applying WIM images from
58 filesystems other than NTFS (with some reduced functionality).
60 The Windows build now extracts short names correctly.
62 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
63 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
64 capture' and `wimlib-imagex apply'.
66 The performance of splitting and joining WIMs should be slightly
69 The LZX and XPRESS compression and decompression functions are now
70 exported from the library.
73 Improvements and bugfixes for the Windows build.
75 Added --strict-acls options.
77 Fixed the way that wimlib determines the order of images in the WIM.
80 Since wimlib can now be used on Windows, wimlib's implementation of
81 ImageX has been renamed to wimlib-imagex to avoid confusion with
82 Microsoft's implementation of ImageX, which would have the same file
83 name ("imagex.exe"). If you really don't like this you can pass the
84 --with-imagex-progname option to `configure' to choose a different name,
85 or even simply rename the binary yourself (but the former way will
86 configure the man pages to use the chosen name).
88 Various bugs fixed in the Windows build. Mainly to do with capturing
89 and restoring alternate data streams correctly in weird cases, and
90 requesting the correct privileges when opening files. Also added the
91 --noacls options to wimlib-imagex capture, append, and apply.
93 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
94 dynamically loaded, so this may make the library compatible with Windows
95 XP (however, there may still be other problems).
98 Added experimental support for native Windows builds. Binaries can be
99 downloaded from the SourceForge page.
101 --source-list option added to `imagex capture' and `imagex append'.
103 Better support for different character encodings.
106 Storing UNIX file owners, groups, and modes in WIM images is now
107 possible using `imagex capture' with the --unix-data flag.
109 Minor bug fixes and documentation fixes.
112 NTFS capture: Fixed capturing duplicate reparse points.
114 NTFS capture: Capture first unnamed stream if there are more than one
115 (print warning instead of error).
117 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
120 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
123 Update to work with ntfs-3g version 2013.1.13.
126 Fixed truncating file to shorter but non-zero length on read-write
129 Various code cleanups and minor documentation fixes.
132 LZX and XPRESS decompression have received some additional optimizations
133 and should now be even faster. (Although, they were already pretty
134 fast--- much faster than typical I/O speeds.)
136 Fixed a bug introduced in v1.2.1 that would cause a directory tree
137 containing hard links to be captured incorrectly in some cases.
140 By default, unmounting a read-write mounted WIM with 'imagex unmount
141 --commit' will now change the WIM in-place without needing to write the
142 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
145 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
146 for a response from the daemon servicing the mounted WIM. Instead,
147 every second 'imagex unmount' will check if the daemon is still alive,
148 and keep waiting if so, otherwise terminate with an error.
150 'imagex unmount --commit' on a read-write mounted WIM will now print
151 progress information regarding the writing of new or modified streams
152 the WIM, just like when capturing or appending a WIM.
154 A small change has been made to XPRESS compression and it should improve
155 the compression ratio slightly.
157 A change was made that may improve performance slightly when applying a
158 WIM image to a NTFS volume.
160 Microsoft has managed to introduce even more bugs into their software,
161 and now the WIMs for Windows 8 have incorrect (too low) reference counts
162 for some streams. This is unsafe because such streams can be removed
163 when they are in actuality still referenced in the WIM (perhaps by a
164 different image). wimlib will now work around this problem by fixing
165 the stream reference counts. This is only done when wimlib_delete_image() is
166 called ('imagex delete') or when wimlib_mount_image() is called with
167 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
168 requires reading the metadata for all images in the WIM, so this will
169 make these operations noticably slower on WIMs with multiple images.
171 Various other bugfixes.
174 Appending images to a WIM is now be done by default without re-building
175 the whole WIM. Use the --rebuild flag to get the old behavior (which
176 was to re-build the entire WIM when a new image is appended).
178 A new command `imagex optimize' is now available to manually re-build a
179 WIM that has wasted space due to repeated appends.
181 Progress information has been improved, and now arbitrary callback
182 functions can be used to show the progress of a WIM operation.
184 A possible bug with changing the bootable image of a WIM was fixed.
186 Some advisory locking is now done to prevent two processes from
187 modifying a WIM at the same time (but only in some cases). For example,
188 you cannot mount two images from a WIM read-write at the same time.
190 Some functions have been reorganized:
191 * wimlib_mount() renamed to wimlib_mount_image().
192 * wimlib_unmount() renamed to wimlib_unmount_image().
193 * wimlib_overwrite_xml_and_header() removed as
194 wimlib_overwrite() suffices now.
195 * wimlib_apply_image_to_ntfs_volume() removed as
196 wimlib_extract_image() suffices now.
197 * wimlib_add_image_from_ntfs_volume() removed as
198 * wimlib_add_image() suffices now.
200 Previously, the soname of libwim.so has been 0.0.0, despite many
201 interface changes. The soname is now updated to 1.0.0 and will now be
202 updated each release.
205 Resources will now be compressed using multiple threads by default.
206 (This applies to `imagex capture', `imagex append', and `imagex
209 Some performance improvements in mounted WIMs.
211 More progress information is shown when capturing a WIM.
214 Lots of minor fixes, code cleanups, and some documentation updates.
215 Nothing in particular is really noteworthy.
218 LZX and XPRESS compression improvements.
220 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
221 Link Bytes of the WIM.
224 Fixed bug when capturing NTFS file with multiple named data streams.
226 Internally, we are now using inode structures, even though these don't
227 appear literally in the WIM file. This simplifies some of the code
228 (mainly for WIM mounting) and likely fixed a few problems, although it
232 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
236 Enough changes to call it version 1.0.0!
238 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
239 to a NTFS volume, is now supported.
241 Hard links and symbolic links have much improved support. They are
242 supported for WIM capture, WIM application, and mounted WIMs (you can
243 even make them on read-write mounted WIMs).
245 Alternate data streams are now supported on mounted WIMs through an
246 xattr or a Windows-style stream interface. Also they are supported when
247 capturing a WIM from NTFS or applying a WIM to NTFS.
249 Split WIMs are better supported. You may now apply an image directly
250 from a split WIM, mount an image from a split WIM read-only, or export
251 an image from a split WIM.
253 Using a capture configuration file is now supported (but not fully yet).
255 SHA1 message digests are checked in more places, so we can make sure
256 applied and captured data is correct.
258 Man pages have been updated and consolidated.
261 Fixed segfault when unmounting read-only WIM.
264 Support for joining and splitting WIMs.
265 Also, security data is now preserved by default.
268 Can now build with older gcc and system headers, like on CentOS 5.
271 Fixed bug that made it impossible to overwrite files in read-write
275 Write byte-order mark before WIM XML data. (imagex.exe requires this to
