When I downloaded OnionShare as a guide from the Whonix wiki, the version of OnionShare is 2.2. The 2.2 version does not include the Chat function, so I want to install and use the 2.4 version, is there a way?
If installing (and digital software verification) from source code perhaps.
Not sure it was documented that way before. Maybe it’s still in the wiki history if it was.
For flatpak instructions (v2.4), see: Dev/OnionShare - Whonix
It is also possible to install using snap, or from the command line (make sure to verify PGP signature if using the command line):
