Unleash 5.0: Dark mode, new project UI and segments, bulk updates, plus some breaking changes

Unleash 5.0 introduces several new features and updates, including the addition of dark mode and enhancements to the project UI, such as the ability to view project stats through new widgets. Users can now apply project-specific segments to better understand the impact of changes and improve collaboration. The release also includes the initial phase of bulk updates, allowing for the efficient management of feature flags, and improvements to the change request process, such as adding comments, descriptive titles, and username visibility. Notably, Unleash 5.0 enforces compatibility with node.js version 18 and above, updates the default database password to "password," and alters the format of error messages, signaling a few breaking changes that users should consider before upgrading.
