HashiCorp has released version 0.4.0 of its Boundary product, which includes features such as brokering of HashiCorp Vault secrets for Boundary targets to end-users, enhanced session cleanup, and foundational features for event logging. The new release adds support for brokering Vault secrets for boundary clients, allowing users to configure Vault credential libraries and stores through the Terraform provider or command-line interface. Additionally, Boundary 0.4 introduces significant enhancements to session cleanup, including logic on the worker side to shut down all connections in the event of a failure to contact the controller after a short period of time.
