Kong Insomnia 11 has been released, offering notable improvements in security, collaboration, and efficiency for users. This update introduces third-party vault integrations, allowing users to manage secrets with services like HashiCorp Vault and AWS Secrets Manager, thereby enhancing security by avoiding plain-text storage of credentials. Additionally, the new Git sync experience enables project-level synchronization, facilitating smoother collaboration by allowing management of all project files within a single Git repository. The release also includes multi-tab support, which enhances productivity by enabling users to manage multiple tasks simultaneously without having to navigate away from the current view, thus streamlining workflow and improving the user experience within the Insomnia application.
