-Version 1.7.1-BETA:
- Made more improvements to the compression algorithms.
+Version 1.7.2-BETA:
+ Made yet another round of performance improvements to the XPRESS, LZX,
+ and LZMS compressors.
+
+ On Windows, wimextract and its underlying library function
+ wimlib_extract_paths() will no longer fail if given a target directory
+ path ending in a slash.
+
+Version 1.7.1:
+ Made more improvements to the XPRESS, LZX, and LZMS compressors.
The default compression mode for wimcapture is now LZX compression in
its default mode, which is the same as '--compress=maximum'.
You can now specify an optional integer compression level to the
- '--compress' or '--solid-compress' options; e.g. '--compress=lzx:75'.
- Currently, the default level in all cases is 50. This capability
- deprecates the '--compress-slow' (or '--recompress-slow') option to
- several wimlib-imagex commands.
-
- The '--pack-streams', '--pack-compress', and '--pack-chunk-size' options
- to several wimlib-imagex commands have been deprecated in favor of more
- "standard" names: '--solid', '--solid-compress', and
- '--solid-chunk-size', respectively.
+ '--compress' option; e.g. '--compress=lzx:75'.
- The XPRESS compressor no longer supports chunks larger than 65536 bytes.
- There is little point in having larger chunks, since the LZ77 sliding
- window for XPRESS cannot be larger than 65536 bytes. This change does
- not affect the default XPRESS chunk size, which is 32768.
+ Made a minor change to the LZMS compressor and decompressor to fix an
+ incompatibility with the Microsoft implementation. In the unlikely
+ event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
+ earlier and a checksum error is reported when extracting files from it
+ with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
+ v1.7.1.
- The new (as of v1.7.0) extraction code will no longer run out of file
- handles when extracting many (1000+) identical files.
+ Added 'verify' subcommand to wimlib-imagex.
- Library changes:
+ Notable library changes:
Custom compressor parameters have been removed from the library
in favor of the simpler level-based API.
Decompressor parameters have been removed entirely.
- The maximum XPRESS chunk size has been reduced, as mentioned
- above.
-
- Library users can now initialize and de-initialize the library
- multiple times in one run of an application program.
-
- Library users will now receive WIMLIB_PROGRESS_MSG_WRITE_STREAMS
- and WIMLIB_PROGRESS_MSG_EXTRACT_STREAMS messages more frequently
- when writing or extracting large WIM files.
-
- Added experimental new write flag:
- WIMLIB_WRITE_FLAG_SEND_DONE_WITH_FILE_MESSAGES.
-
Library users can now specify a custom file for warning and
error messages to be sent to, rather than the default of
standard error.
+ New progress messages:
+ WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
+ WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
+
+ New function: wimlib_verify_wim().
+
Version 1.7.0:
