+as many have (very) often requested, cobalt now lets you pick between several file name format styles!
+go to <span class="text-backdrop">settings > other</span> and change it to whichever you like! there's a preview of each style, so you know how exactly files are gonna look like.
+
+if you liked file names the way they were before, don't worry: classic style is still the default :)
+
+on a different but not any less important note: cobalt is now sponsored by <a class="text-backdrop link" href="https://royalehosting.net/" target="_blank">royalehosting.net</a>!
+overall service performance and stability is gonna be better, but also more content will be possible to download thanks to geniuine server locations. and yes, still no ads or trackers.
+
+this update also includes a bunch of other changes, check them out:
