1. The Batch class is used to process millions of records within normal processing limits. With Batch Apex, we can process records asynchronously to stay within platform limits. If you have a lot of records to process, for example, data cleansing or archiving, Batch Apex is probably your best solution.

2. If the public group has been used in any sharing rule and associated with any records in the context of sharing, the associated records appear. Now, an option is given to delete the public group as well as the sharing of all the records.
3. Restriction rules let you enhance your security by allowing certain users to access only specified records.
