Could you clarify what you mean regarding Zed? I checked just now and it looks like Nixpkgs had the latest version 0.214.7 within 24 hours of its release: https://github.com/NixOS/nixpkgs/pull/466449
About 4mos ago I moved to using brew for zed because at the time there was some hard block on updating rustc in nixpkgs-stable to a version which included some feature that zed relied upon.
