Mac diversion from me here. For CLI software, things are mostly
managed by a package manager like homebrew, macports, fink, etc. But,
for GUI apps (ignoring Mac App Store distributed apps), they commonly
do their own version updating. A very popular technique is to use a
similar kind of library to this one called Sparkle
(https://sparkle-project.org). Though, it has update version check
logic client-side, with just an RSS feed containing entries for app
releases server-side.

Sparkle integration is something I've got on the list to look at with
the Mac build. Basic integration into Inkscape is pretty simple when
adding it to an Obj C app wrapper (the replacement for the <= 0.92.x
Carbon wrapper). The tricky bit is getting it to integrate with a
Inkscape preferences UI to set things like enable version checking,
version check interval, enable beta release channel, etc.

If there's interest in doing a Windows self-updater, it'd be useful to
discuss what would be desired for a preferences UI so we can work out
a common UI for that, if possible.

Cheers,
