For those who are unaware, there is another project [1] that tracks upstream which adds support for various codecs like Zstandard. Many folks (such as myself) opt to install their releases instead.
I prefer NanaZip[1]. It has all the features of the ZS and NSIS fork while being fully compatible with the new Windows context menus.
Perhaps a tangent, but until now, I've only seen or used "codec" in the audio/video sense. While somehow awkward, it seems this would also be correct, since it also compresses and decompresses. Video codec but archive format.
Sometimes you see a word used a new way and wonder if you've just been wrong all these years.
There is also NanaZip which aims to be a more modern Windows application and I think also incorporates the additions of the 7zs fork https://github.com/M2Team/NanaZip
Maybe it's just me but I got weird feelings seeing 7-Zip-zstd repo having more stars than it's upstream.
Note that the official 7z build supports zstd compression since version 24: https://github.com/ip7z/7zip/releases/tag/24.05
