I want to say the Natron compositing software, but I could be misremembering.
I seem to recall it losing it’s only maintainer and therefore being updated or maintained anymore. I want to say this was back in 2018, but since it’s not a piece of kit I use often, I don’t really think about it enough for it to stick in my head. Anyway…point being. It posted a fairly large update in 2022 and has been doing updates since then.
They weren’t even “fully ready” for Ukraine…
