New Release Updates for Administrators
Here are the Top Admin features you can checkout now which will take you to the new levels.
Manual Sharing Records
We can share records and manage records shares through the manual sharing added to the interface. Previously we had to go to salesforce classic to share records with specific users or group o users. Manual sharing is only available for accounts, contacts, opportunities, cases, leads and custom objects
Now create more Roles
The maximum number of roles in the existing org is only 500. Now in Spring ’21 onwards we can create up to 5000 roles, but in order to increase the limit, we need to contact Salesforce support.
Guest Users Permission Update
For now, on the guest users will have only read and create object permissions. That means, in Spring ’21 onwards Salesforce is removing View all, modify all, Edit and Delete object permissions on all objects for guest users in new and existing orgs.
Opportunity Product Relationship
Now you will be able to create relationships to the Opportunity Product object
More Supports added to Dynamic Actions
From now on you can assign actions in the Lightning App Builder instead of the page layouts. You can apply filters to control when and where the actions will appear for users. You use the Dynamic Actions, to first add the Highlight Panel to the record page and then click on Upgrade Now to complete the migration. After that all the migrated actions will appear. Click one of the existing ones  and then click on Add Filter  to control when and where the actions will appear for users or click on Add Action  to add a new action.
