Change to libsoup-3. I really don't know if this can compatible with soup 2.4. I test it on fedora. Add i18n format date display.

Line 1 (extension.js) should be removed because the version is set here: https://gitlab.gnome.org/GNOME/gnome-shell/-/blob/9d47062c3282b0f103d25a5d3412f28d7766c252/js/ui/environment.js#L36-44 Why don't you can check the current version like this: ```js if (imports.gi.versions.Soup === '2.4') { // 2.4 } else { // 3.0 } ```

I just don't know if the js/ui/environment.js has been launched every time when login. If true, the _injectSoup3Compat(Soup); line at https://gitlab.gnome.org/GNOME/gnome-shell/-/blob/9d47062c3282b0f103d25a5d3412f28d7766c252/js/ui/environment.js#L36-44 had do the compatible thing and I only need write with soup3, right? I dislike write those branch to judge version. :D And someone using manjaro(based on Arch) report an issue about the Soup version, I also don't know which soup version be used in his distro. Maybe '2.6' not '2.4', how can I do with this situation.

When you set the version in extension.js, it won't do anything. Because it has been set before in the GNOME Shell environment. and yes, the `js/ui/environment.js` sets the GNOME Shell environments and it will be loaded on each start: https://gitlab.gnome.org/GNOME/gnome-shell/-/blob/9d47062c3282b0f103d25a5d3412f28d7766c252/js/ui/init.js#L5

Thanks, It so clear now, only `js/ui/environment.js` loaded before main.js. I upload other version, please reject this version. :D
