Why might a developer need to change the linked repository branch for a project's environment?

Changing the linked repository branch for a project's environment can often be driven by new developments within the project. As a project evolves, features might be developed in separate branches to allow for iterative changes and improvements without disrupting the main codebase. When these developments are ready to be integrated or tested, a developer might need to switch the linked branch to ensure that the environment reflects the latest changes and features being worked on.

For instance, if new features or fixes have been implemented on a specific branch and the team needs to preview or test those in a development or staging environment, switching to the updated branch enables the environment to access and run the latest code. This practice is essential for maintaining alignment between what is being developed and what is being tested, facilitating effective collaboration and integration of new features.
