How do you prioritize regression tasks under tight deadlines (need to release by Friday)?

In a tight deadline, I prioritize regression testing as follows:

1. Critical business functions: I check the main scenarios that affect the product and user experience (e.g., authorization, payment, order creation).

2. Functionality affected by changes: I test the parts that were changed or depend on them.

3. High-priority bug regressions: I verify that previously fixed critical bugs have not reappeared.

4. Minimal set of stability tests: Basic interface and performance checks.

Thus, the focus is on maximum efficiency within limited time to minimize release risks.
