7-zip 22.00 – APFS, Posix TAR, high precision timestamps
Looking back at this version history [1], there was perviously a gap of 3.5 years between releases (2011-2014). Skimming through the discussion forums, the 2.5yr gap between 19.00 and 21.07 was filled with a number of alpha and beta releases, eg 20.02 [2]. Version numbering seems to follow a consistent yy.## format since 2015.

And it's not like they're 60, they're twenty! I thought it was more known
Also, unlike WinRAR, 7zip is open-source. Code mirror here: https://github.com/kornelski/7z

7zip > winRAR change my mind
It's also open source.

How safe is 7Zip encryption?
AES is only as good as the KDF protecting the key. Looking at the github mirror of its code (updated march 2019), it seems to be using PBKDF2-SHA1 with 1,000 iterations. That's actually really bad because SHA1 is weak, and 1,000 iterations is very low.

Ubuntu 23.04 (Lunar Lobster)
nearly every main distro I am aware of has both available. The reason you still see p7zip is because the CLI incompatibilities vs the newer 7z/7zip executables and the general licensing issues. Most users of "old p7zip" are actually using the actively maintained https://github.com/p7zip-project/p7zip which is updated, supporting unix permissions and zstd and so on.

7-zip 22.00 – APFS, Posix TAR, high precision timestamps
Thank you for pointing this out! This is the source of much confusion. Although Arch for example uses https://github.com/jinfeihan57/p7zip which seems to be reasonably maintained?
- Ark and 7-zip
-
Replace p7zip with upstream 7-Zip
Then you can compile p7zip from source: $ mkdir p7zip-git $ cd p7zip-git $ git clone https://github.com/jinfeihan57/p7zip .
- Don't Use RAR
- TIL there's a fork of the unmaintained p7zip port of 7-Zip
- I can't compress in 7zip with Ark and p7zip
-
will arch replace p7zip with normal 7-zip?
April 4th was the latest release. Had some commits in May. I think it is active.
-
Why is 7z so outdated?
I think the point is, the '7z' at 17.04 available in Arch Linux's repo is actually p7zip, the development of which is independent of 7-zip. So comparison of the version number is meaningless (if I am right). Also, p7zip 17.04 is released in April this year, not 2017, according to its release page
