Which versions of 7z.dll are supported?

[fhaag]

I would like to upgrade to the latest version of SevenZipSharp and the underlying 7z.dll, but I am not sure which version of the DLL to use (or where to get a suitable version from).

• There is a version in this SevenZipSharp repository, but it is two years old.
• There is a download for the latest version on the original 7zip website (labeled "7-Zip Extra: standalone console version, 7z DLL, Plugin for Far Manager"), but that one only contains 7za.dll and I don't really want support for "only 7zip archives".
• I could take the 7z.dll out of my local 7zip (application) installation, but that feels somehow "wrong" and makes me wonder whether there isn't an official, dedicated way to download the DLL for redistribution.

The project last shipped with 18.05, if I recall. I am using the 7z.dll out of my local 7z install from 19.01 (If I recall). It hasn't had any issues that I'm aware of.

@fhaag: I've only been testing with the version currently in the repository (which is explicitly not included in the NuGet release), though it might be an idea to update that (as you say, it's getting outdated).

In general I've seen no issues with using any (fairly recent) versions.

I guess I could contact Igor/7z and ask about it, but in general I'd like to keep the library "simpler" by not bundling it with anything.
