Google Cloud CLI Removes Legacy Cloud SQL Proxy V1 Component

The August 25, 2026 release notes for Google Cloud highlight several updates, including a breaking change in the Cloud SDK. According to the official changelog, version 582.0.0 of the Google Cloud CLI has removed the legacy Cloud SQL Proxy V1 component ('cloud_sql_proxy'). All connect commands now rely exclusively on Cloud SQL Auth Proxy V2 ('cloud-sql-proxy'). This marks a shift in default behavior for users who previously depended on the older proxy version.

Operators should verify whether their existing workflows or automation scripts explicitly reference the legacy Cloud SQL Proxy V1. If so, these scripts will fail unless updated to use Cloud SQL Auth Proxy V2. Additionally, any dependencies or configurations tied to the legacy proxy should be reviewed to ensure compatibility with the newer version. This change reflects a broader trend in cloud tools to phase out legacy components in favor of more secure or feature-rich alternatives.
