# What's changed in v19.1.0

> Auth template rendering can honor the real outbound request and custom request properties, plus a fix for the `appTester` type signature

*Released: 2026-07-30*

This release improves auth template extraction and rendering: templates can now honor the real outbound request and integration-specific custom request properties when selecting credentials, non-auth request bodies are kept out of extracted templates, and `z.request(url, options)` calls are handled correctly during extraction. It also fixes the `appTester` TypeScript signature to accept request templates.

## cli

None!

## core

* Thread `targetRequest` through `renderAuthTemplate` so rendering can honor the real outbound request ([#1298](https://github.com/zapier/zapier-platform/pull/1298))
* Support `customRequestProperties` in the `renderAuthTemplate` bundle, letting integration middleware select the right credential during rendering ([#1322](https://github.com/zapier/zapier-platform/pull/1322))
* Drop non-auth request bodies from extracted auth templates ([#1323](https://github.com/zapier/zapier-platform/pull/1323))
* Preserve `z.request(url, options)` options in auth-template request stubs, and honor `customRequestProperties` during template extraction ([#1324](https://github.com/zapier/zapier-platform/pull/1324))
* Support request templates in the `appTester` type signature ([#1302](https://github.com/zapier/zapier-platform/pull/1302))
