Releasing this on April 1 may have been suboptimal, but I had seen the draft before and was already positively impressed back then. I'm especially happy about the scalability of the original vector graphic – why is the logo at the top left still a PNG, though?
Topic on Project talk:Proposal for changing logo of MediaWiki, 2020
I don't think MediaWiki's logo configuration supports SVGs.
That's not true! (Or at least it worked nicely enough when I used one a year or two ago)
The Timeless skin still shows the old logo for me.
Not the case for me, can you refresh/purge the cache?
Thanks so it is simply a cache issue.
