This requires build slaves to be + updated to Nix 1.8. + + - Nix now uses HTTPS instead of HTTP to access the default binary + cache, `cache.nixos.org`. + + - `nix-env` selectors are now regular expressions. For instance, you + can do + + $ nix-env -qa '.*zip.*' + + to query all packages with a name containing `zip`. + + - `nix-store --read-log` can now fetch remote build logs. If a build + log is not available locally, then ‘nix-store -l’ will now try to + download it from the servers listed in the ‘log-servers’ option in + nix.conf. For instance, if you have the configuration option + + log-servers = http://hydra.nixos.org/log + + then it will try to get logs from `http://hydra.nixos.org/log/base + name of the + store path`. This allows you to do things like: + + $ nix-store -l $(which xterm) + + and get a log even if `xterm` wasn't built locally. + + - New builtin functions: `attrValues`, `deepSeq`, `fromJSON`, + `readDir`, `seq`. + + - `nix-instantiate --eval` now has a `--json` flag to print the + resulting value in JSON format. + + - `nix-copy-closure` now uses `nix-store --serve` on the remote side + to send or receive closures. This fixes a race condition between + `nix-copy-closure` and the garbage collector. + + - Derivations can specify the new special attribute + `allowedRequisites`, which has a similar meaning to + `allowedReferences`. But instead of only enforcing to explicitly + specify the immediate references, it requires the derivation to + specify all the dependencies recursively (hence the name, + requisites) that are used by the resulting output. + + - On Mac OS X, Nix now handles case collisions when importing closures + from case-sensitive file systems. This is mostly useful for running + NixOps on Mac OS X. + + - The Nix daemon has new configuration options `allowed-users` + (specifying the users and groups that are allowed to connect to the + daemon) and `trusted-users` (specifying the users and groups that + can perform privileged operations like specifying untrusted binary + caches). + + - The configuration option `build-cores` now defaults to the number of + available CPU cores. + + - Build users are now used by default when Nix is invoked as root. + This prevents builds from accidentally running as root. + + - Nix now includes systemd units and Upstart jobs. + + - Speed improvements to `nix-store + --optimise`. + + - Language change: the `==` operator now ignores string contexts (the + “dependencies” of a string). + + - Nix now filters out Nix-specific ANSI escape sequences on standard + error. They are supposed to be invisible, but some terminals show + them anyway. + + - Various commands now automatically pipe their output into the pager + as specified by the PAGER environment variable. + + - Several improvements to reduce memory consumption in the evaluator. + +This release has contributions from Adam Szkoda, Aristid Breitkreuz, Bob +van der Linden, Charles Strahan, darealshinji, Eelco Dolstra, Gergely +Risko, Joel Taylor, Ludovic Courtès, Marko Durkovic, Mikey Ariel, Paul +Colomiets, Ricardo M.
