New Features

  • New script-aware commands: `pixi init --script`, `pixi add --script`, `pixi remove --script`, and `pixi lock --script`.
  • Configuration option `experimental.conda-script` to enable the feature.
  • Shared `tool.pixi` support across different script formats.

Upgrade Notes

The older release is for the shadcn-ui library, while the newer release is for the Pixi package manager. These are unrelated tools and cannot be upgraded from one to the other.
