Happened to notice that FindFacts is defaulted for Isabelle2024/AFP2024? Any plan to keep it update-to-date?

I hope it would be up-to-date. :-)

Yes; however, we will switch to the Find_Facts now distributed with Isabelle. The switch will happen with the next release (Isabelle2025-1).

What I would love to see is concept extraction (as demonstrated by the SErAPIS prototype) also integrated in Find_Facts, but so far nobody has stepped up to build this.

Lovely to know! Just be curious: since Find_Facts can search through AFP, if Find_Facts is to be bundled with Isabelle distribution, will AFP be bundled with the distribution (so Find_Facts can search locally) or will Find_Facts check AFP over the Internet?

Could be a student project :-) though long-term maintaining has always been a problem.

Only the library is indexed in the release. To search the AFP, you'll have to use the web version over the internet.

Find_Facts is now deployed in that version, and for AFP-2025-1 -- enjoy! Also feel free to DM me if you have feedback.

Thanks for letting me know.
For clarity, could you tell me what you mean by "Find_Facts now distributed with Isabelle"?
E.g., can we now use Find_Facts through Isabelle/jEdit?
