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