This feature allows the user to require that a field's values be unique inside of that column. When this is configured, the system will not let two records have the same value for that field, behaving similarly to a key to that entry.

Evolving the extensibility of system objects through objects framework, this feature allows users to create and update System Object entries through Object Actions as they can with Custom Objects.

This feature adds read-only support for all object fields types, making sure users are not able to update those fields from both the UI or APIs, only the system can: through default values or actions, for example.

This feature adds a new field type “Date and Time”. A Datetime value stores a year, month, day, time, and time zone. With this field, users will also be able to create time ranges, manage priorities and order entries well, and to give more context and assertiveness to the data.
