HISTORY of the 7-Zip\r
--------------------\r
\r
-16.01 2016-05-19\r
+18.05 2018-04-30\r
-------------------------\r
+- The speed for LZMA/LZMA2 compressing was increased \r
+ by 8% for fastest/fast compression levels and \r
+ by 3% for normal/maximum compression levels.\r
+- 7-Zip now shows Properties (Info) window and CRC/SHA results window\r
+ as "list view" window instead of "message box" window.\r
+- Some improvements in zip, hfs and dmg code.\r
+- Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode in\r
+ Windows 10 because of some BUG with "Large Pages" in Windows 10. \r
+ Now 7-Zip doesn't use "Large Pages" on Windows 10 up to revision 1709 (16299).\r
+- The vulnerability in RAR unpacking code was fixed (CVE-2018-10115).\r
- Some bugs were fixed.\r
+ \r
+\r
+18.03 beta 2018-03-04\r
+-------------------------\r
+- The speed for single-thread LZMA/LZMA2 decoding\r
+ was increased by 30% in x64 version and by 3% in x86 version.\r
+- 7-Zip now can use multi-threading for 7z/LZMA2 decoding,\r
+ if there are multiple independent data chunks in LZMA2 stream.\r
+- 7-Zip now can use multi-threading for xz decoding,\r
+ if there are multiple blocks in xz stream.\r
+- New localization: Kabyle.\r
+- Some bugs were fixed.\r
+\r
+\r
+18.01 2018-01-28\r
+-------------------------\r
+- 7-Zip now can unpack DMG archives that use LZFSE compression method.\r
+- 7-Zip now doesn't allow update operation for archives that have read-only attribute.\r
+- The BUG was fixed:\r
+ extracting from tar with -si switch didn't set timestamps for directories.\r
+- Some bugs were fixed.\r
+\r
+\r
+18.00 beta 2018-01-10\r
+-------------------------\r
+- 7-Zip now can unpack OBJ/COFF files.\r
+- new -sse switch to stop archive creating, if 7-Zip can't open some input file. \r
+- Some bugs were fixed.\r
+\r
+\r
+17.01 beta 2017-08-28\r
+-------------------------\r
+- Minor speed optimization for LZMA2 (xz and 7z) multi-threading compression.\r
+ 7-Zip now uses additional memory buffers for multi-block LZMA2 compression.\r
+ CPU utilization was slightly improved.\r
+- 7-zip now creates multi-block xz archives by default. Block size can be \r
+ specified with -ms[Size]{m|g} switch.\r
+- xz decoder now can unpack random block from multi-block xz archives.\r
+ 7-Zip File Manager now can open nested multi-block xz archives \r
+ (for example, image.iso.xz) without full unpacking of xz archive.\r
+- 7-Zip now can create zip archives from stdin to stdout.\r
+- 7-Zip command line: @listfile now doesn't work after -- switch.\r
+ Use -i@listfile before -- switch instead.\r
+- The BUGs were fixed:\r
+ 7-Zip could add unrequired alternate file streams to WIM archives, \r
+ for commands that contain filename wildcards and -sns switch.\r
+ 7-Zip 17.00 beta crashed for commands that write anti-item to 7z archive.\r
+ 7-Zip 17.00 beta ignored "Use large memory pages" option.\r
+\r
+\r
+17.00 beta 2017-04-29\r
+-------------------------\r
+- ZIP unpacking code was improved.\r
+- 7-Zip now reserves file space before writing to file (for extraction from archive).\r
+ It can reduce file fragmentation.\r
+- Some bugs were fixed. 7-Zip could crash in some cases.\r
+- Internal changes in code.\r
+\r
+\r
+16.04 2016-10-04\r
+-------------------------\r
+- The bug was fixed: 7-Zip 16.03 exe installer under Vista didn't create \r
+ links in Start / Programs menu.\r
+- Some bugs were fixed in RAR code.\r
+\r
+\r
+16.03 2016-09-28\r
+-------------------------\r
+- Installer and SFX modules now use some protection against DLL preloading attack.\r
+- Some bugs were fixed in 7z, NSIS, SquashFS, RAR5 and another code.\r
\r
\r
-16.00 2016-05-10\r
+16.02 2016-05-21\r
-------------------------\r
- 7-Zip now can extract multivolume ZIP archives (z01, z02, ... , zip).\r
- Some bugs were fixed.\r
