v0.11.1 - 2023-09-14

This release makes multiple changes to better handle errors that get raised from the DiagnosticReport. The report should be able to run to completion now and have any errors that it encounters reported in a column on the details that can be observed from running get_details. It also resolves many warnings that were interrupting the printing of the report's results and progress.

v0.11.0 - 2023-08-10

This release adds a function that allows users to plot the cardinality of foreign and primary keys in synthetic data. More specifically, it graphs the frequency that each number of children per parent row occurs in the parent table.
