 # hubData (development version)
 
+* Support the determination of hub schema from v4 configuration files (#63). Also fixes bug in `create_hub_schema()` where `output_type_id` data type was being incorrectly auto-determined as `logical` when only point estimate output types where being collected by a hub. Now `character` data type is returned for the `output_type_id` for all schema versions in such situations when auto-determined.

 # hubData 1.2.3
 
 * Fix bug in `create_hub_schema()` where `output_type_id` data type was being incorrectly determined as `Date` instead of `character` (Reported in https://github.com/reichlab/variant-nowcast-hub/pull/87#issuecomment-2387372238).
