nvd changelog

0.2.4 (unreleased)

Added an nvd history command for diffing successive generations of a profile, issue #18. Big thanks to Felix Uhl for the idea and implementation!
Added --sort option for controlling the order packages are listed in, for issue #17.
In the "Version changes" section of a diff, highlight the portions of version numbers that have changed, i.e., everything after the part common to all versions (issue #17). This makes it easier to spot whether packages have had major or minor version bumps. The colour scheme used is selectable with the --version-highlight option.
Respect the NO_COLOR environment variable and disable colour when it is set and nonempty (when the default --color=auto is used). For more info see: https://no-color.org

Fix compatibility with nix-2.3 where nix --extra-experimental-features isn't a known flag yet. We have to switch on the version of Nix we've been given.
Stricter behaviour around invoking nix. Nix returning a nonzero exit code will cause nvd to abort in most cases.

Fixed crash when nix-store --query --references returns nothing (e.g. for a Nix package with no dependencies), which causes the assertion from issue #12 to fail.

Fixed reference to undefined variable in StorePath constructor (issue #12), plus some code lint.

Add display of the change in closure disk size (issue #8).
Add a --nix-bin-dir option for allowing easier control over which Nix binaries are used (issue #9).

Add a mandatory action argument to the CLI. The existing diff functionality is under the diff command. A new list command is now implemented as well (issue #5).
Optimized first level dependency calculation to read depenencies from nix-store rather than walking a directory tree manually (issue #4). This also fixes nvd's support for things other than simple buildEnvs, e.g. file entries at the top level of the store, derivations, and references in files other than symlinks.

Initial release.
