# Release 0.6 (2004-11-14)
|
|
|
|
- Rewrite of the normalisation engine.
|
|
|
|
- Multiple builds can now be performed in parallel (option `-j`).
|
|
|
|
- Distributed builds. Nix can now call a shell script to forward
|
|
builds to Nix installations on remote machines, which may or may
|
|
not be of the same platform type.
|
|
|
|
- Option `--fallback` allows recovery from broken substitutes.
|
|
|
|
- Option `--keep-going` causes building of other (unaffected)
|
|
derivations to continue if one failed.
|
|
|
|
- Improvements to the garbage collector (i.e., it should actually work
|
|
now).
|
|
|
|
- Setuid Nix installations allow a Nix store to be shared among
|
|
multiple users.
|
|
|
|
- Substitute registration is much faster now.
|
|
|
|
- A utility `nix-build` to build a Nix expression and create a symlink
|
|
to the result int the current directory; useful for testing Nix
|
|
derivations.
|
|
|
|
- Manual updates.
|
|
|
|
- `nix-env` changes:
|
|
|
|
- Derivations for other platforms are filtered out (which can be
|
|
overridden using `--system-filter`).
|
|
|
|
- `--install` by default now uninstall previous derivations with
|
|
the same name.
|
|
|
|
- `--upgrade` allows upgrading to a specific version.
|
|
|
|
- New operation `--delete-generations` to remove profile
|
|
generations (necessary for effective garbage collection).
|
|
|
|
- Nicer output (sorted, columnised).
|
|
|
|
- More sensible verbosity levels all around (builder output is now
|
|
shown always, unless `-Q` is given).
|
|
|
|
- Nix expression language changes:
|
|
|
|
- New language construct: `with
|
|
E1;
|
|
E2` brings all attributes defined in the attribute set *E1* in
|
|
scope in *E2*.
|
|
|
|
- Added a `map` function.
|
|
|
|
- Various new operators (e.g., string concatenation).
|
|
|
|
- Expression evaluation is much faster.
|
|
|
|
- An Emacs mode for editing Nix expressions (with syntax highlighting
|
|
and indentation) has been added.
|
|
|
|
- Many bug fixes.
