Dagger 0.16 has been released with several features and improvements that simplify workflows, enhance security, and provide a smoother overall experience for users. The update includes secure secrets management with integrations to HashiCorp Vault and 1Password, allowing teams to securely retrieve credentials at any stage of execution without preloading them into their environment. Additionally, performance improvements have been made, including faster module loading times, reduced extraneous files loaded from the source repository, and improved cache utilization. The update also introduces a new engine configuration file, `engine.json`, which simplifies the format and adds Dagger-specific fields.
