···28282929- `libxcrypt`, the library providing the `crypt(3)` password hashing function, is now built without support for algorithms not flagged [`strong`](https://github.com/besser82/libxcrypt/blob/v4.4.33/lib/hashes.conf#L48). This affects the availability of password hashing algorithms used for system login (`login(1)`, `passwd(1)`), but also Apache2 Basic-Auth, Samba, OpenLDAP, Dovecot, and [many other packages](https://github.com/search?q=repo%3ANixOS%2Fnixpkgs%20libxcrypt&type=code).
30303131+- `boot.bootspec.enable` (internal option) is now enabled by default because [RFC-0125](https://github.com/NixOS/rfcs/pull/125) was merged. This means you will have a bootspec document called `boot.json` generated for each system and specialisation in the top-level. This is useful to enable advanced boot usecases in NixOS such as SecureBoot.
