Hello fellow penguins!

I you play Stellaris on GNU/Linux, and bought the GOG version, you might be quite fed up having to download the full game for each update, wasting gigabytes data transfer each time.

Well, good news, I got you covered ;)
Like I previously did for games like Wasteland 2 (thanks to the initiative of an inXile developer) and Pillars of Eternity, I now build custom patches for Stellaris. Said patches can be found on the following page:
https://downloads.dotslashplay.it/patches/stellaris/

All patches use the same naming template:
stellaris-gog-linux_x.x.x_y.y.y.delta.xz
where x.x.x is the game version you have currently installed,
and y.y.y is the game version you want to patch your game to.

Using one of these patches is really easy, and only require that you have the `rdiffdir` command available, provided by the duplicity backup tool: http://duplicity.nongnu.org/

Let’s assume you downloaded the patch "stellaris-gog-linux_2.3.1.2_2.3.3.delta.xz" in "~/downloads/" and your game is installed in "~/games/stellaris/".
Then all you have to do is run these two commands: Wait a couple minutes, when your console prompt is back, it means your game is patched and ready to be enjoyed!
