Describe the main goal of isolating changes in separate branches before merging into main: - To eliminate the need for testing before release - To ensure independent versions of the application for production and development without merge - To maintain the stability of the main branch - To avoid conflicts during collaborative development

The main goal of isolating changes in separate branches before merging into main is to maintain the stability of the main branch.

This allows developers to work independently without disrupting the production code. Isolation helps identify and fix errors in a separate branch before merging, which reduces the risk of breaking the main branch.

Other options listed are not the main goal:

• Eliminating the need for testing before release — on the contrary, testing is mandatory.
• Ensuring independent versions without merge — usually changes are still merged.
• Avoiding conflicts — isolation helps, but conflicts can also occur when working in branches.

Thus, the stability of the main branch is a key factor.
