SHOPIFY CLI PATCHES LOCALE HEADER LEAK, CLEANS UP TEST INFRASTRUCTURE

By RepoJournal · Filed · About Shopify

A security fix landed overnight that tightens locale-sensitive header redaction in Shopify CLI, while the team continues stripping out filesystem mocks from the test suite.

The CLI caught a locale header redaction bug [1] that could expose sensitive information in certain contexts. It's a narrow fix but important enough to land as breaking, so audit your deployments if you're running CLI in multi-locale environments. In parallel, the team is methodically removing filesystem mocks from the test layer [2] , replacing them with cleaner abstractions. This is defensive work that makes the test suite more reliable and faster to run. The README also shed its hardcoded "3.0" version reference [3] , a small move that keeps docs from aging into obsolescence. These aren't headline features, but they're the kind of housekeeping that keeps a CLI tool stable and maintainable.
