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 (CVE-2018-10115).
Some bugs were fixed.
New localization: Kabyle.

7z.exe b -slp
18.01 на 1709 даже после снятия галочки использования больших страниц и перезагрузки, всё равно показывает lp в бенче.
опция в gui и ключ slp не связаны?
18.05 ведёт себя так же?

I.e. the 8/3% improvement is on top of what we already had with 18.03 ?

Not sure why that is, since it works here without having changed any security settings (i.e. a clean 1803). I'm guessing you're not running with default security settings, maybe having enabled some of the enhanced protections, where this kind of error would be semi-expected?

Having same issue as Pesala. As a workaround, right-click on the MSI/EXE, and select PROPERTIES. You may have a checkbox that states something similar to "Unblock File". Place a check in the checkbox, and try installing again.

Hello,
I have problem with 7-zip installation.
I try to install 7-zip using 7z1805-x64.msi file. The installer ask me for:
"The following applications are using files that needs to be updated by this setup. Close these applications and then click Retry to continue the installation or Cancel to exit it. Explorer process."
There is no way to force installer close explorer.exe. Ok, i can kill explorer.exe manually, but i want to use silently install on some PC and this situation cause installation process to fail in silently mode.
I have Windows 10 x64 1709, in system already installed 7-zip 16.04 x64.
Yes, i can uninstall it before install new version and it will work for me (I think), but i need to run silently installations on some different PCs with different version of installed 7-zip and manually uninstall old version or killing explorer.exe process is not a good way.!
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
If you are seeing the window above, that means a file is currently in use, which is why the install is getting stuck and asking what it should do.
I would try again with the switches /qn /promptrestart and see if it does what you're looking for. You may also have to run the install process with the /a (admin) switch.

Hi Igor,
In 18.01 you had fixed CVE-2018-5996 with adding some variable like _errorMode or m_TablesOK.
And in 18.05 I don't see this variables. You were replace it by _solidAllowed to fix CVE-2018-10115. In 18.05, Does it fix for both CVE-2018-5996 and CVE-2018-10115?
Thank you

If the "Use large memory pages" option is ON, then 7-Zip 18.01 (7zfm.exe) sends
-slpto Benchmark (7zg.exe).For 7-Zip 18.05 on Windows 1709:
1) 7zfm.exe doesn't send
-slpto 7zg.exe2) 7zg.exe and 7z.exe ignore
-slp.-slp9can be used in 7-Zip 18.05, if you still want to test "large pages" on Windows 1709.Last edit: Igor Pavlov 2018-05-02

18.05 contains only some small changes over 18.04 beta.
But changes after 18.03 beta are big.

When "list view" window is active press ctrl+a then ctrl+c and copy where you want (ctrl+v).

Thanks for the update. Windows 10 1803 won't run the installer as it's from an unknown publisher.
Not sure why that is, since it works here without having changed any security settings (i.e. a clean 1803). I'm guessing you're not running with default security settings, maybe having enabled some of the enhanced protections, where this kind of error would be semi-expected?
Just click onto "other info" or similar and continue installing.
Still can't create .iso from the command line...
Hi, here is an update to my translation of brazilian portuguese.
Will there be a new version of p7zip as well? The linux version seems pretty unmaintained considering the last release was 16.02.
The p7zip is idepended project and I use p7zip v16.02 for FreeBSD UNIX - new version don't exist.
Having same issue as Pesala. As a workaround, right-click on the MSI/EXE, and select PROPERTIES. You may have a checkbox that states something similar to "Unblock File". Place a check in the checkbox, and try installing again.
Hello,
I attached Japanese lang file for 18.05 version.
You can create thread or post in "Patches" section, and describe why your new translation is better than current translation.
OK. I will create a new thread.
I deleted the attached file once.
Thank you.

Hello,
Since you are using the .msi installer, you can use some advanced command line switches to help in your application deployment.

Yes, latest code in 7-Zip 18.05 must fix all these things.
Thank you very much!
