40 slices of Nix-related goodness for your perusal
Determinate Nix 3.22.2 moves onto upstream Nix 2.35, gives nix eval a --drv-link flag that keeps the garbage collector away from freshly instantiated derivations, and makes nix copy fast again against older daemons.
The CRA will take effect in two stages, with reporting obligations beginning on September 11, 2026. Compliance is likely to be a hurdle for many enterprises, but we're confident that Nix and Determinate provide an industry-leading solution.
Determinate Nix 3.21.9 makes evaluation measurably faster by reusing fetcher cache results, and teaches Determinate Nixd to pick the right trusted cache keys when you point it at FlakeHub's FedRAMP environment
It's the Rust-native, Nix-aware companion to FlakeBOM that turns SBOMs from a report on what exists on a system into something you can act on
Determinate Nixd now routes FlakeHub Cache requests to the nearest cache node, making substitution faster for most users, especially those outside the United States
An all-and-sundry batch of performance work, a faster nix copy, multi-threaded store optimization, and speedier binary caches, remote stores, and parallel evaluation, plus some changes to Determinate Secure Packages and flake schemas
