1 Only the most important changes more recent than version 0.6 are noted here.
4 Capturing a WIM image should now be significantly faster in most cases
5 due to improved use of the operating system's cache and avoiding reading
6 files twice whenever possible.
8 The Windows build should now work on Windows XP.
10 The Windows build now supports capturing and restoring hidden,
11 compressed, sparse, and encrypted files.
13 The Windows build now supports capturing and applying WIM images from
14 filesystems other than NTFS (with some reduced functionality).
16 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
17 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
18 capture' and `wimlib-imagex apply'.
20 The performance of splitting and joining WIMs should be slightly
23 The LZX and XPRESS compression and decompression functions are now
24 exported from the library.
27 Improvements and bugfixes for the Windows build.
29 Added --strict-acls options.
31 Fixed the way that wimlib determines the order of images in the WIM.
34 Since wimlib can now be used on Windows, wimlib's implementation of
35 ImageX has been renamed to wimlib-imagex to avoid confusion with
36 Microsoft's implementation of ImageX, which would have the same file
37 name ("imagex.exe"). If you really don't like this you can pass the
38 --with-imagex-progname option to `configure' to choose a different name,
39 or even simply rename the binary yourself (but the former way will
40 configure the man pages to use the chosen name).
42 Various bugs fixed in the Windows build. Mainly to do with capturing
43 and restoring alternate data streams correctly in weird cases, and
44 requesting the correct privileges when opening files. Also added the
45 --noacls options to wimlib-imagex capture, append, and apply.
47 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
48 dynamically loaded, so this may make the library compatible with Windows
49 XP (however, there may still be other problems).
52 Added experimental support for native Windows builds. Binaries can be
53 downloaded from the SourceForge page.
55 --source-list option added to `imagex capture' and `imagex append'.
57 Better support for different character encodings.
60 Storing UNIX file owners, groups, and modes in WIM images is now
61 possible using `imagex capture' with the --unix-data flag.
63 Minor bug fixes and documentation fixes.
66 NTFS capture: Fixed capturing duplicate reparse points.
68 NTFS capture: Capture first unnamed stream if there are more than one
69 (print warning instead of error).
71 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
74 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
77 Update to work with ntfs-3g version 2013.1.13.
80 Fixed truncating file to shorter but non-zero length on read-write
83 Various code cleanups and minor documentation fixes.
86 LZX and XPRESS decompression have received some additional optimizations
87 and should now be even faster. (Although, they were already pretty
88 fast--- much faster than typical I/O speeds.)
90 Fixed a bug introduced in v1.2.1 that would cause a directory tree
91 containing hard links to be captured incorrectly in some cases.
94 By default, unmounting a read-write mounted WIM with 'imagex unmount
95 --commit' will now change the WIM in-place without needing to write the
96 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
99 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
100 for a response from the daemon servicing the mounted WIM. Instead,
101 every second 'imagex unmount' will check if the daemon is still alive,
102 and keep waiting if so, otherwise terminate with an error.
104 'imagex unmount --commit' on a read-write mounted WIM will now print
105 progress information regarding the writing of new or modified streams
106 the WIM, just like when capturing or appending a WIM.
108 A small change has been made to XPRESS compression and it should improve
109 the compression ratio slightly.
111 A change was made that may improve performance slightly when applying a
112 WIM image to a NTFS volume.
114 Microsoft has managed to introduce even more bugs into their software,
115 and now the WIMs for Windows 8 have incorrect (too low) reference counts
116 for some streams. This is unsafe because such streams can be removed
117 when they are in actuality still referenced in the WIM (perhaps by a
118 different image). wimlib will now work around this problem by fixing
119 the stream reference counts. This is only done when wimlib_delete_image() is
120 called ('imagex delete') or when wimlib_mount_image() is called with
121 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
122 requires reading the metadata for all images in the WIM, so this will
123 make these operations noticably slower on WIMs with multiple images.
125 Various other bugfixes.
128 Appending images to a WIM is now be done by default without re-building
129 the whole WIM. Use the --rebuild flag to get the old behavior (which
130 was to re-build the entire WIM when a new image is appended).
132 A new command `imagex optimize' is now available to manually re-build a
133 WIM that has wasted space due to repeated appends.
135 Progress information has been improved, and now arbitrary callback
136 functions can be used to show the progress of a WIM operation.
138 A possible bug with changing the bootable image of a WIM was fixed.
140 Some advisory locking is now done to prevent two processes from
141 modifying a WIM at the same time (but only in some cases). For example,
142 you cannot mount two images from a WIM read-write at the same time.
144 Some functions have been reorganized:
145 * wimlib_mount() renamed to wimlib_mount_image().
146 * wimlib_unmount() renamed to wimlib_unmount_image().
147 * wimlib_overwrite_xml_and_header() removed as
148 wimlib_overwrite() suffices now.
149 * wimlib_apply_image_to_ntfs_volume() removed as
150 wimlib_extract_image() suffices now.
151 * wimlib_add_image_from_ntfs_volume() removed as
152 * wimlib_add_image() suffices now.
154 Previously, the soname of libwim.so has been 0.0.0, despite many
155 interface changes. The soname is now updated to 1.0.0 and will now be
156 updated each release.
159 Resources will now be compressed using multiple threads by default.
160 (This applies to `imagex capture', `imagex append', and `imagex
163 Some performance improvements in mounted WIMs.
165 More progress information is shown when capturing a WIM.
168 Lots of minor fixes, code cleanups, and some documentation updates.
169 Nothing in particular is really noteworthy.
172 LZX and XPRESS compression improvements.
174 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
175 Link Bytes of the WIM.
178 Fixed bug when capturing NTFS file with multiple named data streams.
180 Internally, we are now using inode structures, even though these don't
181 appear literally in the WIM file. This simplifies some of the code
182 (mainly for WIM mounting) and likely fixed a few problems, although it
186 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
190 Enough changes to call it version 1.0.0!
192 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
193 to a NTFS volume, is now supported.
195 Hard links and symbolic links have much improved support. They are
196 supported for WIM capture, WIM application, and mounted WIMs (you can
197 even make them on read-write mounted WIMs).
199 Alternate data streams are now supported on mounted WIMs through an
200 xattr or a Windows-style stream interface. Also they are supported when
201 capturing a WIM from NTFS or applying a WIM to NTFS.
203 Split WIMs are better supported. You may now apply an image directly
204 from a split WIM, mount an image from a split WIM read-only, or export
205 an image from a split WIM.
207 Using a capture configuration file is now supported (but not fully yet).
209 SHA1 message digests are checked in more places, so we can make sure
210 applied and captured data is correct.
212 Man pages have been updated and consolidated.
215 Fixed segfault when unmounting read-only WIM.
218 Support for joining and splitting WIMs.
219 Also, security data is now preserved by default.
222 Can now build with older gcc and system headers, like on CentOS 5.
225 Fixed bug that made it impossible to overwrite files in read-write
229 Write byte-order mark before WIM XML data. (imagex.exe requires this to
