Most changes and updates in Netrunner Rolling are performed automatically during updates, however there are a few things that are not, and would require manual changes (if desired).
The Netrunner Rolling theme was updated automatically and pulled in the new wallpaper as well. So in realty, the only thing needing to be done would be to apply the new wallpaper manual (if desired), or to select “use layout” in the theme dialog and reapply the theme. Keep in mind doing the latter will also reset your panel, wallpaper, and system tray to the Netrunner defaults.
We replaced gtk3 with gtk3-classic, and firefox with firefox-kde-opensuse (patched for better plasma integration, and global menu support).
We also now ship the ISO with the firefox-integration package installed (available in the repositories) as well as apply the plasma-browser-integration extension (available under /usr/lib/firefox/distribution/extensions/, or via the Firefox addons site).
We’ve also added the appimagelauncher package (available in the repositories).
If I think of any other changes since the 2017.07 ISO that may need to be done manually, I’ll post them here.
