Solidity 0.8.35 just shipped. I tried two things that actually matter: the new erc7201 builtin (three lines of dangerous keccak math become one safe annotation) and the 0.9.0 keyword warnings (so you can fix your codebase today before the next major lands). In this video I add layout at erc7201("amys.tipjar") to a TipJar contract, verify the slot math against forge inspect AND a hand-rolled Python keccak, then trigger the keyword-promotion warning by naming a variable `layout`.
