Octopus Deploy Release 4.0

Octopus Deploy 4.0 introduces a revamped user interface and enhanced user experience, transitioning from Angular 1.4 to React and Redux to improve usability and scalability. The update emphasizes ease of use, incorporating Google's material design guidelines and offering features like filters, search controls, and consistent actions to streamline navigation and management of projects. The deployment release page has been simplified for easier customization, and the infrastructure page has been redesigned to better accommodate large-scale environments. Additionally, the release includes several breaking changes and performance optimizations, such as limiting simultaneous deployments to 10 targets by default and refining API functionalities, while also requiring certain post-install data fixes during the upgrade process.
