# Description the plan of deprecating `source` never really came to conclusion, so i propose to move it out of the deprecated commands in this PR. i've moved it to `nu-command::misc`, which can be changed 👍 # User-Facing Changes ``` $nothing ``` # Tests + Formatting - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - ⚫ `toolkit test` - ⚫ `toolkit test stdlib` # After Submitting ``` $nothing ```
