App

• Function limit increased from 10 to 50 per app.
• --notify flag on app dev. You can now specify --notify when running app dev to update a file or URL when files in your theme app extension are changed. This supports integrations with other tools.
• Default web type. Webs now default to frontend type, so it no longer needs to be specified. This is the recommended pattern for monolithic apps.
• auth_callback_path for monolithic apps. When working with a monolithing app with only a frontend web, you can now specify auth_callback_path in its shopify.web.toml.
• Support .jpeg files in theme app extensions. Previously only the .jpg extension was recognized.
• Install exact versions of dependencies. When adding dependencies to your app, the CLI ensures they are pinned to an exact version.
• Fix: Link to view checkout extensions. Always link to a published product for viewing checkout extensions. Unpublished products led to an error page.
• Fix: Clean up after failing to generate extensions. Previously if a failure occurred while generating an extension, a directory with invalid contents would remain. Now that directory will be deleted.
• Fix: Deploying function-only apps. Previously apps with only function extensions would fail to build and deploy; this is fixed.
• Fix: npm peerDependency resolution. When using npm as package manager, generating a react UI extension failed due to conflicts between installed copies of react. Dependency installation strategy is adapted to solve this.
• Fix: Obtaining a port when HOST is specified. When the HOST environment variable is specified, obtaining a random port failed; this is fixed.

Theme

• --notify flag on theme dev. You can now specify --notify when running theme dev to update a file or URL when files are changed. This supports integrations with other tools.
• Upgrade theme-check to 1.15.0. Changelog here
• --update-docs flag on theme check. You can now synchronously update Theme Check resources (objects, filters, and tags) before running it. This ensures that your code is checked against the most updated version of theme resources.
• Fix: Support vanity URLs on theme dev. Some elements, including images and fonts, were broken for vanity URLs. They are now displayed correctly.
• Fix: localhost link issue on theme dev. In some scenarios, the localhost link was being hidden.
• Fix: /localization and /cart requests on theme dev. Now, these endpoints will no longer fail when using shopify theme dev.

UI (applicable across project types)

• No-color mode. You can use the NO_COLOR=1 environment variable or --no-color flag to disable color in the CLI. Note that there is only partial support for some commands thus far.
• Specific error message in non-interactive terminals. If the CLI attempts to prompt in a non-interactive terminal (such as in CI), a clear error appears, making it obvious that a required flag is missing.
• Clean up after errors. When the CLI process encounters an error and quits, any hanging prompts or the taskbar will be cleared before exit, leaving only relevant logs.

Auth (applicable across project types)

• Support for Google Cloud Shell. Add support for authentication in Google Cloud Shell.
