unRAR is a utility to extract, test and view the contents of archives
created with the RAR archiver, version 1.50 and above. The unRAR
utility is a minor part of the RAR archiver and contains RAR
uncompression algorithm. UnRAR requires very small volume of memory to
operate.
The license for this software states that "the code may not be used to
develop a RAR (WinRAR) compatible archiver."
This version exists for compatibility with legacy systems that lack a
C++11 compiler.
v3.18.1
=======
No significant changes.
v3.18.0
=======
Features
--------
- Bypass ZipFile.namelist in glob for better performance. (#106)
- Refactored glob functionality to support a more generalized solution with support for platform-specific path separators. (#108)
Bugfixes
--------
- Add special accounting for pypy when computing the stack level for text encoding warnings. (#114)
5.6.1 (2024-03-09)
* liblzma: Fixed two bugs relating to GNU indirect function (IFUNC)
with GCC. The more serious bug caused a program linked with
liblzma to crash on start up if the flag -fprofile-generate was
used to build liblzma. The second bug caused liblzma to falsely
report an invalid write to Valgrind when loading liblzma.
* xz: Changed the messages for thread reduction due to memory
constraints to only appear under the highest verbosity level.
* Build:
- Fixed a build issue when the header file <linux/landlock.h>
was present on the system but the Landlock system calls were
not defined in <sys/syscall.h>.
- The CMake build now warns and disables NLS if both gettext
tools and pre-created .gmo files are missing. Previously,
this caused the CMake build to fail.
* Minor improvements to man pages.
* Minor improvements to tests.
lxqt-archiver-0.9.1 / 2024-02-21
===================================
* Support the use of 7zip instead of p7zip with the new option `USE_7Z` (`OFF` by default), especially for Debian-based systems.
* Updated to new mimetype names of shared-mime-info ≥ 2.3.
* Fixed extraction of multiple archives.
v0.13.74
* disabled local file header offset64
* allowed to 'make fortify' for extended debugging
* fixed all memleak bugs from address sanitizer
* fixed ZIP64 bugs - but the support is still incomplete
* fixed remaining failures as they were recorded in testsuite
release 0.13.73
* fixed last cmake bug - parallel builds can lead to race condition
* abolished centos8 testbuilds and prepared ubuntu24
* integrated some github patches
* prepare autoformat with clang-format (not yet enforced)
5.6.0 (2024-02-24)
This bumps the minor version of liblzma because new features were
added. The API and ABI are still backward compatible with liblzma
5.4.x and 5.2.x and 5.0.x.
NOTE: As described in the NEWS for 5.5.2beta, the core components
are now under the BSD Zero Clause License (0BSD).
Since 5.5.2beta:
* liblzma:
- Disabled the branchless C variant in the LZMA decoder based
on the benchmark results from the community.
- Disabled x86-64 inline assembly on x32 to fix the build.
* Sandboxing support in xz:
- Landlock is now used even when xz needs to create files.
In this case the sandbox is has to be more permissive than
when no files need to be created. A similar thing was
already in use with pledge(2) since 5.3.4alpha.
- Landlock and pledge(2) are now stricter when reading from
more than one input file and only writing to standard output.
- Added support for Landlock ABI version 4.
* CMake:
- Default to -O2 instead of -O3 with CMAKE_BUILD_TYPE=Release.
-O3 is not useful for speed and makes the code larger.
- Now builds lzmainfo and lzmadec.
- xzdiff, xzgrep, xzless, xzmore, and their symlinks are now
installed. The scripts are also tested during "make test".
- Added translation support for xz, lzmainfo, and the
man pages.
- Applied the symbol versioning workaround for MicroBlaze that
is used in the Autotools build.
- The general XZ Utils and liblzma API documentation is now
installed.
- The CMake component names were changed a little and several
were added. liblzma_Runtime and liblzma_Development are
unchanged.
- Minimum required CMake version is now 3.14. However,
translation support is disabled with CMake versions
older than 3.20.
- The CMake-based build is now close to feature parity with the
Autotools-based build. Most importantly a few tests aren't
run yet. Testing the CMake-based build on different operating
systems would be welcome now. See the comment at the top of
CMakeLists.txt.
* Fixed a bug in the Autotools feature test for ARM64 CRC32
instruction support for old versions of Clang. This did not
affect the CMake build.
* Windows:
- The build instructions in INSTALL and windows/INSTALL*.txt
were revised completely.
- windows/build-with-cmake.bat along with the instructions
in windows/INSTALL-MinGW-w64_with_CMake.txt should make
it very easy to build liblzma.dll and xz.exe on Windows
using CMake and MinGW-w64 with either GCC or Clang/LLVM.
- windows/build.bash was updated. It now works on MSYS2 and
on GNU/Linux (cross-compiling) to create a .zip and .7z
package for 32-bit and 64-bit x86 using GCC + MinGW-w64.
* The TODO file is no longer installed as part of the
documentation. The file is out of date and does not reflect
the actual tasks that will be completed in the future.
* Translations:
- Translated lzmainfo man pages are now installed. These
had been forgotten in earlier versions.
- Updated Croatian, Esperanto, German, Hungarian, Korean,
Polish, Romanian, Spanish, Swedish, Vietnamese, and Ukrainian
translations.
- Updated German, Korean, Romanian, and Ukrainian man page
translations.
* Added a few tests.
Summary of new features added in the 5.5.x development releases:
* liblzma:
- LZMA decoder: Speed optimizations to the C code and
added GCC & Clang compatible inline assembly for x86-64.
- Added lzma_mt_block_size() to recommend a Block size for
multithreaded encoding.
- Added CLMUL-based CRC32 on x86-64 and E2K with runtime
processor detection. Similar to CRC64, on 32-bit x86 it
isn't available unless --disable-assembler is used.
- Optimized the CRC32 calculation on ARM64 platforms using the
CRC32 instructions. Runtime detection for the instruction is
used on GNU/Linux, FreeBSD, Windows, and macOS. If the
compiler flags indicate unconditional CRC32 instruction
support (+crc) then the generic version is not built.
- Added definitions of mask values like
LZMA_INDEX_CHECK_MASK_CRC32 to <lzma/index.h>.
* xz:
- Multithreaded mode is now the default. This improves
compression speed and creates .xz files that can be
decompressed in multithreaded mode. The downsides are
increased memory usage and slightly worse compression ratio.
- Added a new command line option --filters to set the filter
chain using the liblzma filter string syntax.
- Added new command line options --filters1 ... --filters9 to
set additional filter chains using the liblzma filter string
syntax. The --block-list option now allows specifying filter
chains that were set using these new options.
- Ported the command line tools to Windows MSVC.
Visual Studio 2015 or later is required.
* Added lz4 support to xzdiff/xzcmp and xzgrep.
5.5.2beta (2024-02-14)
* Licensing change: The core components are now under the
BSD Zero Clause License (0BSD). In XZ Utils 5.4.6 and older
and 5.5.1alpha these components are in the public domain and
obviously remain so; the change affects the new releases only.
0BSD is an extremely permissive license which doesn't require
retaining or reproducing copyright or license notices when
distributing the code, thus in practice there is extremely
little difference to public domain.
* liblzma
- Significant speed optimizations to the LZMA decoder were
made. There are now three variants that can be chosen at
build time:
* Basic C version: This is a few percent faster than
5.4.x due to some new optimizations.
* Branchless C: This is currently the default on platforms
for which there is no assembly code. This should be a few
percent faster than the basic C version.
* x86-64 inline assembly. This works with GCC and Clang.
The default choice can currently be overridden by setting
LZMA_RANGE_DECODER_CONFIG in CPPFLAGS: 0 means the basic
version and 3 means that branchless C version.
- Optimized the CRC32 calculation on ARM64 platforms using the
CRC32 instructions. The instructions are optional in ARMv8.0
and are required in ARMv8.1 and later. Runtime detection for
the instruction is used on GNU/Linux, FreeBSD, Windows, and
macOS. If the compiler flags indicate unconditional CRC32
instruction support (+crc) then the generic version is not
built.
* Added lz4 support to xzdiff/xzcmp and xzgrep.
* Man pages of xzdiff/xzcmp, xzgrep, and xzmore were rewritten
to simplify licensing of the man page translations.
* Translations:
- Updated Chinese (simplified), German, Korean, Polish,
Romanian, Spanish, Swedish, and Ukrainian translations.
- Updated German, Korean, Romanian, and Ukrainian man page
translations.
* Small improvements to the tests.
* Added doc/examples/11_file_info.c. It was added to the Git
repository in 2017 but forgotten to be added into distribution
tarballs.
* Removed doc/examples_old. These were from 2012.
* Removed the macos/build.sh script. It had not been updated
since 2013.
5.5.1alpha (2024-01-26)
* Added a new filter for RISC-V binaries. The filter can be used
for 32-bit and 64-bit binaries with either little or big
endianness. In liblzma, the Filter ID is LZMA_FILTER_RISCV (0x0B)
and the xz option is --riscv. liblzma filter string syntax
recognizes this filter as "riscv".
* liblzma:
- Added lzma_mt_block_size() to recommend a Block size for
multithreaded encoding
- Added CLMUL-based CRC32 on x86-64 and E2K with runtime
processor detection. Similar to CRC64, on 32-bit x86 it
isn't available unless --disable-assembler is used.
- Implemented GNU indirect function (IFUNC) as a runtime
function dispatching method for CRC32 and CRC64 fast
implementations on x86. Only GNU/Linux (glibc) and FreeBSD
builds will use IFUNC, unless --enable-ifunc is specified to
configure.
- Added definitions of mask values like
LZMA_INDEX_CHECK_MASK_CRC32 to <lzma/index.h>.
- The XZ logo is now included in the Doxygen generated
documentation. It is licensed under Creative Commons
Attribution-ShareAlike 4.0.
* xz:
- Multithreaded mode is now the default. This improves
compression speed and creates .xz files that can be
decompressed multithreaded at the cost of increased memory
usage and slightly worse compression ratio.
- Added new command line option --filters to set the filter
chain using liblzma filter string syntax.
- Added new command line options --filters1 ... --filters9 to
set additional filter chains using liblzma filter string
syntax. The --block-list option now allows specifying filter
chains that were set using these new options.
- Added support for Linux Landlock as a sandboxing method.
- xzdec now supports pledge(2), Capsicum, and Linux Landlock as
sandboxing methods.
- Progress indicator time stats remain accurate after pausing
xz with SIGTSTP.
- Ported xz and xzdec to Windows MSVC. Visual Studio 2015 or
later is required.
* CMake Build:
- Supports pledge(2), Capsicum, and Linux Landlock sandboxing
methods.
- Replacement functions for getopt_long() are used on platforms
that do not have it.
* Enabled unaligned access by default on PowerPC64LE and on RISC-V
targets that define __riscv_misaligned_fast.
* Tests:
- Added two new fuzz targets to OSS-Fuzz.
- Implemented Continuous Integration (CI) testing using
GitHub Actions.
* Changed quoting style from `...' to '...' in all messages,
scripts, and documentation.
* Added basic Codespell support to help catch typo errors.
# 1.2 [2024-02-22]
* fix a build error on windows
* improve log file handling
* add -e and -l options to set (or disable) error log file and logging directory
* revert zip64 format changes from last release
* update included source for minizip to version from zlib-1.3.1
* various fixes and code cleanup
Changes in version 1.24:
The option '--empty-error', which forces exit status 2 if any empty member
is found, has been added.
The option '--marking-error', which forces exit status 2 if the first LZMA
byte is non-zero in any member, has been added.
File diagnostics have been reformatted as 'PROGRAM: FILE: MESSAGE'.
Diagnostics caused by invalid arguments to command-line options now show the
argument and the name of the option.
The option '-o, --output' now preserves dates, permissions, and ownership of
the file when (de)compressing exactly one file.
The option '-o, --output' now creates missing intermediate directories when
writing to a file.
The variable MAKEINFO has been added to configure and Makefile.in.
2.1.6
This is a stable release, with several minor improvements and one corruption fix for inflateCopy().
This release also improves on the functable implementation, and also moves its initialization to happen in deflateInit() and inflateInit(). We also have some optimizations for RVV and ARM.
2.1.5
This is a hotfix release, fixing an issue where certain applications would fail with a checksum error during inflate (decompression).
2.1.4
This is a stable release, with several minor improvements and one fix for a possible buffer overrun while using inflateCopy().
Zlib-ng's zlib-compat mode is now targeting zlib 1.3 compatibility.
Of note, we have new optimizations for ARM and Risc-V RVV, and a lot of fixes and improvements to the buildsystem.
5.4.6 (2024-01-26)
* Fixed a bug involving internal function pointers in liblzma not
being initialized to NULL. The bug can only be triggered if
lzma_filters_update() is called on a LZMA1 encoder, so it does
not affect xz or any application known to us that uses liblzma.
* xz:
- Fixed a regression introduced in 5.4.2 that caused encoding
in the raw format to unnecessarily fail if --suffix was not
used. For instance, the following command no longer reports
that --suffix must be used:
echo foo | xz --format=raw --lzma2 | wc -c
- Fixed an issue on MinGW-w64 builds that prevented reading
from or writing to non-terminal character devices like NUL.
* Added a new test.

5.0
Changes to the library:
It is now possible to specify a codec for archive entry metadata (pathname, linkpath, uname and gname)
BREAKING: If you use the archive_read_class and archive_write_class arguments, the classes you provide will receive a codec name as a second positional argument.
The timestamp_nsec arguments of the legacy ArchiveEntry.set_{a,c,m}time methods are now optional
Changes to the tests and packaging:
Removed obsolete dependencies (mock and six) from tox.ini
Always use UTF-8 when reading the PKG-INFO and README.rst files
Replaced pytest-xdist with pytest-forked in tox.ini
Dropped testing with Python 3.7. Added 3.10 and 3.11
4.0
BREAKING & SECURITY: The archive extraction functions now pass 3 security flags (SECURE_NODOTDOT, SECURE_NOABSOLUTEPATHS and SECURE_SYMLINKS) to libarchive by default, unless the current directory is the root.
BREAKING: The ArchiveEntry properties atime, mtime, ctime, birthtime and size now have the value None instead of 0 when they're unset.
BREAKING: The ArchiveEntry.pathname property now attempts to decode bytes using UTF-8. This breaks reading archives that contain file names which look like UTF-8 but aren't, if such a thing exists. Proper support of encodings will probably be added in the next version.
Multiple entries from the same archive can now be kept in memory, however only the current entry's content can be read.
The filetype, linkpath, size, mode, redvmajor, redvminor, uid and gid attributes of an archive entry can now be modified.
The four time properties of archive entries now have setters, so for example entry.set_mtime(0, 0) can be replaced by entry.mtime = 0.
Archive entries have 4 new properties: perm, rdev, uname and gname.
When adding files to an archive, a destination path can now be specified.
The ArchiveRead class now has a bytes_read property.
The ArchiveWrite class now has a bytes_written property.
Python 3.6 is no longer tested.
The documentation has been improved.

Thanks to our new contributor: @miller-alex
These are questions about the target system, whose files at
build-time are all relative to ${_CROSS_DESTDIR} if it is defined,
i.e., if USE_CROSS_COMPILE is set to yes.
No change to native builds because ${_CROSS_DESTDIR:U} is empty in
them. (Possible minor change by adding :Q to ${H_FOO} in command
lines, but if this makes a difference it likely fixes problems.)
Version 4.1 (2023-09-17)
Features:
* Support 7zip/p7zip as decompression backend.
* RAR5: check password before trying to read file (chigusa)
New APIs:
* Make get_rar_version a public function (Safihre)
* New option: ``part_only`` for :class:`RarFile`,
to read only single file and allow it to be middle-part
of multi-volume archive.
* Add :meth:`RarFile.printdir`, use it in dumprar. Needed to examine
FILE_COPY or HARD_LINK entries that do not contain data.
Fixes:
* Use OS separator to access filename. Should fix
subdirectory entry access on Windows.
* DirectReader: check seek position on each read.
Fixes read reading from multiple entries in parallel
on RarFile backed by file object.
* DirectReader: properly disable CRC check when seeking.
* Reset _hdrenc_main before processing a new volume.
Fixes CRC checks on multi-volume reads.
* Adapt to Python 3.10 argparse (MeggyCal)
* SFX: Handle volume numbering special cases better.
* nsdatetime: support pypy internal use
* Throw error if backend does not support passwords.
Cleanups:
* ci: Use proper unrar on Windows. MingW one tolaretes
paths with ``/`` better than upstream build.
* ci: Add Python 3.10 to the testing (Christian Clauss)
* Avoid isascii, not in 3.6
