JuliaCon 2026 Proceedings - Submission question

Dear JuliaCon team, I gave a talk at this years Juliacon ( Modeling optical setups with BeamletOptics.jl :: JuliaCon 2026 :: pretalx) and wanted to submit a paper to the proceedings. Upon submission via the form linked in the author guide I get this error mesage: I have searched the forums and found that the proceedings last year were announced in October. Do I need to wait for a call for submissions or is this a technical issue? Kind regards, Hugo
