7-Zip 19.02 alpha released

What's new after 7-Zip 19.00:
sourceforge.net/p/sevenzip/discussion/45797/thread/2839b954b9/#d7ae
7-Zip now can unpack files encoded with Base64 encoding (b64 filename extension).
7-Zip now can use new x86/x64 hardware instructions for SHA-1 and SHA-256, supported
by AMD Ryzen and latest Intel CPUs: Ice Lake and Goldmont.
It increases
the speed of SHA-1/SHA-256 hash value calculation,
the speed of encryption/decryption in zip AES,
the speed of key derivation for encryption/decryption in 7z/zip/rar archives.
The speed of zip AES encryption and 7z/zip/rar AES decryption was increased with
the following improvements:
7-Zip now can use new x86/x64 VAES (AVX Vector AES) instructions, supported by
Intel Ice Lake CPU.
The existing code of x86/x64 AES-NI was improved also.
There is 2% speed optimization in 7-Zip benchmark's decompression.
Some bugs were fixed.

The source code of new version and another additional packages will be released later after some testing period.

interested in seeing the benches for this

based

Someone made some benchmarks with a ryzen, open OP link and scroll down in the comments

and still can't compress multiple folders as different files like winrar is doing for over 15 years

>7z extraction speeds are still horrible
7z is FOSS garbage shilled by people who never did any real work with archives. Even scene groups are smart enough to avoid this pile of shit called 7z

now add it to the UI and maybe it worth a shit for people whose time is worth money

>I'm too important to learn how to read or how to use a computer

lol okay retard

Why can't you just copy the WinRAR interface to the GUI? Why does it have to suck?

Try Bandizip.

Just use GNU tar and zstd format

Keep coping 7z tards. In the end .rar has better/more features and has a better performance/compression ratio with rar5. All the scene groups are using .rar as well because 7z is so fucking bad. Handling split archives with 7z is a pain, typical foss garbage. Weeb incels gonna cope.

Why hasn't there been any improvements in compression efficiency during the last 10 years ?

What makes you think there hasn't been?

>using a format optimized for tape drives
the sad thing is that most formats that have file index and compress before packing don't support proper metadata, though

I mean in 7zip specifically

>In the end .rar has better/more features and has a better performance/compression ratio with rar5.
false

>Handling split archives with 7z is a pain, typical foss garbage.
false

idk man, ive gor all this stuff built into dolphin. I think its just an .ark integration though.

>false
You can't do incremental/differential with split archives in 7-zip.
I didn't try with WinRAR yet, but some user said you can.

than do it in python,
dirs = os.listdir()
for dir in dirs:
os.system(f'7z.exe a "{dir}.zip" "{dir}"')

How?
I found this
winrar.exe a -se -ag+YYYYMMDD_diff_ -k -m4 -ms -os -r -ep1 -ao e:\mydoc.rar @mydocpath.txt

It works if there's a single existing .rar, but what do I enter if there are many of them (part01, part02...)?

That's horrible
At least make a small attempt at not writing such horrid scripts
for f in ./*; do [[ -d $f ]] && 7z a "./$(basename "$f").7z" "$f"; done

>using shell
The whole world knows Python. Nobody cares about shell scriot.

mkdir -- $'--help\nrm -rf *'
Have fun with your python script
(also, it zips files too, not just folders)
