Pulumi's 3.23.0 release introduces the ability to disable default providers, addressing a popular community request and enhancing control over cloud deployments. This update allows users to define explicit providers in their code, ensuring predictable and consistent resource deployments across different regions and accounts by avoiding unexpected behavior that may arise from default providers. The change is particularly beneficial for complex scenarios like multi-region deployments or when deploying to newly created Kubernetes clusters, where explicit providers are necessary. Users can disable default providers on a per-stack basis by specifying the relevant package names in the configuration file using the `pulumi:disable-default-providers` setting, effectively preventing unintentional reliance on default system configurations and improving deployment reliability.
