Unleash 4.18: Direct client-side front-end API access, sync user groups, and clone environments

Unleash 4.18 introduces several new features aimed at simplifying client-side feature flagging and enhancing user group management. One of the most significant updates is the direct client-side access to the front-end API, eliminating the need for a proxy and reducing the complexity of setting up feature toggling, although proxies may still be beneficial for handling high traffic loads or when hosting multiple proxies close to users. The update also allows syncing user groups via Single Sign-On (SSO), streamlining user management by automatically updating access based on group changes in the SSO provider. Additionally, enterprise users can now clone entire environments, facilitating testing or project duplication, with the ability to generate an API token immediately for the cloned environment. These enhancements collectively aim to improve ease of use, scalability, and management efficiency for Unleash users.
