Registry v3.3.0 introduces the concept of Data Filters, a plugin-based mechanism to modify or filter data in certain contexts:

To set up Data Filters, first instantiate the appropriate plugin via ConfigurationData Filters. Add a new Data Filter of the appropriate type, set the context, and provide any plugin specific configuration. If the plugin does not support the appropriate context, an error will be thrown.

Once the Data Filter is configured, it must be attached somewhere to be used.

From this page, add or manage the Data Filters. Note that Filters can be ordered, in case it is important for one filter to run before another.
