+cobalt is finally moving to its own domain! many of you have been anticipating this, and many kept forgetting the link due to how cryptic it was.
+
+well, worry no more - <span class="text-backdrop">cobalt.tools</span> is here.
+
+if you haven't yet, open <a class="text-backdrop link" href="https://co.wukko.me" target="_blank">co.wukko.me</a> to transfer your settings here! no additional action from you is required. just open the old link and cobalt will do everything for you :)
+
+make sure to <span class="text-backdrop">update your bookmarks</span> and reinstall the web app!
+
+here's what domain change means:
+- still no ads, same owner, same features, same reliability. just a way more rememberable link (it's literally two words).
+- cobalt.tools makes it clear that cobalt is a tool and that it's "cobalt", not "wukko".
+- i can host various versions of cobalt on subdomains without links looking awkward.
+- i can host cobalt-related websites without polluting my personal domain's dns (such as crowdin).
+- i stand by same privacy policies (and in fact am using the same exact server as before).
+
+the domain change is required for the future of cobalt.
+
+here's what's coming soon:
+- support for many top-requested sites, such as (but not limited to) twitch and niconico.
+- education version of cobalt, as often requested by students and educators.
+- major localization system upgrade, allowing for simpler community contributions.
+- region-specific versions with 100% translations and tweaks.
+- native clients for desktop and mobile (not sure about this one, i'm no superman).
+- ...and more!
+
+now, here's what's new in 7.4:
+- tabs in popups now scroll to top on tab bar tap.
+- padding across web app was tuned.
+- (obviously) a migration agent. soon will be used for importing and exporting settings.
+- some minor clean ups in codebase.
+
+if you want to help cobalt achieve goals listed above, consider donating! donations are the only way i can keep cobalt ad-less, powerful, (basically) limitless, and also 100% free.
+
+in fact, donations have helped me grow cobalt more than i've ever anticipated. just imagine how much better it will be in a year.
+
+go to donations down below to find ways to donate!
+
+thank you for reading through all of this. i hope you enjoy this update and have a great day :D
