Seems like the new update kind of performed a critical hit on the basic search functionality. This affects the Library and the upper Main Menubar search button.
In order to give you folks a quick and dirty workaround until the developers unfuck their crap, in the upper right corner on the right sidebar, there is now a search field on top of the Patreon link.
It is not ideal, but it will work for now. I will try to figure out if I can do something from my side.
addendum – Shoutbox is also wonky but still working. Fucks sake. If this does not improve, I might overhaul the whole site this week.
