Session with the Coq Development Team
summary
Coq 8.13 ships with a new warning for hints and a staged migration: marking hints global preserves old behavior while the default will flip later, so compile, fix imports, and silence warnings incrementally; notation printing now prefers the most specific notation or the most recently imported one, changing some displays; native evaluation is easier via an opt‑in cognative package that AOT‑compiles lambda terms (works but can blow memory on some OCaml versions); kernel adds primitive persistent arrays and a definitional UIP for sprop (consistency caveat); cumulative inductives bug is partially fixed, full fix targets 8.14.
