Pull request 24287 rejects unchecked archives, resources and outside patches, including cached downloads, when installing through the API, and extends auditing to patches, versioned head resources and full stable git revisions across taps. Pull request 24285…
Separately, cask reliability gets a fix for data loss during upgrades. Pull request 24295 shares a private, locked-down directory for a single cask operation so sandbox cleanup cannot delete backups waiting to be restored, keeps that directory on failure with its path reported for recovery, and cleans up scratch…
