7-Zip 19.00 (32-bit) for PC Windows

The speed for LZMA/LZMA2 compressing was increased by 3-10% and there are minor changes in compression ratio.
Some bugs were fixed.
The bug in 7-Zip 18.02-18.05 was fixed: there was memory leak in xz decoder.
7-Zip 18.02-18.05 used only one CPU thread for bz2 archive creation.

The speed for single-thread LZMA/LZMA2 decoding was increased by 30% in x64 version and by 3% in x86 version.
7-Zip now can use multi-threading for 7z/LZMA2 decoding, if there are multiple independent data chunks in LZMA2 stream.
7-Zip now can use multi-threading for xz decoding, if there are multiple blocks in xz stream.
The speed for LZMA/LZMA2 compressing was increased by 8% for fastest/fast compression levels and by 3% for normal/maximum compression levels.
7-Zip now shows Properties (Info) window and CRC/SHA results window as "list view" window instead of "message box" window.
Some improvements in zip, hfs and dmg code.
Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode in Windows 10 because of some BUG with "Large Pages" in Windows 10. Now 7-Zip doesn't use "Large Pages" on Windows 10 up to revision 1709 (16299).
The vulnerability in RAR unpacking code was fixed.
Some bugs were fixed.

Some bugs were fixed.

7-Zip now can unpack DMG archives that use LZFSE compression method.
7-Zip now doesn't allow update operation for archives that have read-only attribute.
The BUG was fixed:
Extracting from tar with -si switch didn't set timestamps for directories.
Some bugs were fixed.

7-Zip now can unpack OBJ/COFF files.
New -sse switch to stop archive creating, if 7-Zip can't open some input file.
Some bugs were fixed.

Minor speed optimization for LZMA2 (xz and 7z) multi-threading compression.
7-Zip now uses additional memory buffers for multi-block LZMA2 compression.
CPU utilization was slightly improved.
7-zip now creates multi-block xz archives by default. Block size can be specified with -ms[Size]{m|g} switch.
xz decoder now can unpack random block from multi-block xz archives.
7-Zip File Manager now can open nested multi-block xz archives (for example, image.iso.xz) without full unpacking of xz archive.
7-Zip now can create zip archives from stdin to stdout.
7-Zip command line: @listfile now doesn't work after -- switch.
Use -i@listfile before -- switch instead.
The BUGs were fixed:
7-Zip could add unrequired alternate file streams to WIM archives, for commands that contain filename wildcards and -sns switch.
7-Zip 17.00 beta crashed for commands that write anti-item to 7z archive.
7-Zip 17.00 beta ignored "Use large memory pages" option.

ZIP unpacking code was improved.
7-Zip now reserves file space before writing to file (for extraction from archive). It can reduce file fragmentation.
Some bugs were fixed. 7-Zip could crash in some cases.
Internal changes in code.

- The bug was fixed: 7-Zip 16.03 exe installer under Vista didn't create links in Start / Programs menu.
- Some bugs were fixed in RAR code.

- Installer and SFX modules now use some protection against DLL preloading attack.
- Some bugs were fixed in 7z, NSIS, SquashFS and RAR5 code.

- The BUG in 16.00 - 16.01 was fixed: 7-Zip mistakenly reported the warning "There are some data after the end of the payload data" for split archives.

- Some bugs were fixed.

- 7-Zip now can extract multivolume ZIP archives (z01, z02, ... , zip).
- Some bugs were fixed.

* 7-Zip File Manager:
- The code for "Open file from archive" operation was improved.
- The code for "Tools/Options" window was improved.
- The BUG was fixed: there was incorrect mouse cursor capture for drag-and-drop operations from open archive to Explorer window.
