# Description As suggested by @WindSoilder, since plugins can now contain both simple commands that produce `Value` and commands that produce `PipelineData` without having to choose one or the other for the whole plugin, this change merges `stream_example` into `example`. # User-Facing Changes All of the example plugins are renamed. # Tests + Formatting - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` # After Submitting - [ ] Check nushell/nushell.github.io for any docs that match the command names changed
