Pulumi Environments, Secrets, and Configuration (ESC) has introduced a new suite of versioning features that enhance control and confidence in managing environments by creating immutable revision histories, enabling side-by-side revision comparisons, and allowing the tagging and importing of specific versions. These features, which include the ability to rollback to previous versions and retract revisions, aim to prevent disasters, improve auditing, and streamline development workflows. The versioning capabilities are available across different editions of Pulumi Cloud and can be accessed through both the ESC CLI and the Pulumi Cloud Console. This development is expected to significantly enhance the security, reliability, and auditability of deployments, while also supporting agile practices and fostering collaboration among teams.
