 ## 1.3.0 - 2023-08-14
 
+This release adds two new methods to the `MultiTableMetadata`: `detect_from_csvs` and `detect_From_dataframes`. These methods allow you to detect metadata for a whole dataset at once by either loading them from a folder or a dictionary mapping table names to the `pandas.DataFrames`. It also improves the visualization of multi-table metadata by adding the `summarized` option to the `show_table_details` parameter. This will print each sdtype in the table and the number of columns that have that sdtype.
+
+Additionally, this release patches a bug that prevented custom constraints from working on columns that were primary or alternate keys. It also adds support for Python 3.11!
