# What's changed in v18.5.1

> Actionable error when app definition fails to load, `platformData` removed from bundle, docs and `help` updated to use `zapier-platform` binary name

*Released: 2026-04-30*

This patch release improves the error message you get when an app definition fails to load, removes `platformData` from the bundle, and finishes the rename of the CLI binary from `zapier` to `zapier-platform` across docs and the `help` command.

We're renaming `zapier` to `zapier-platform` because the `zapier` binary name will be allocated to the [Zapier SDK](https://docs.zapier.com/sdk). The `zapier` binary still works in v18, but in the next major release (v19), we'll officially remove it — you'll need to use `zapier-platform` instead. If `zapier-platform` is too long to type, you can set up a shell alias like `alias zp=zapier-platform`.
