Datasette 1.0a9. A new Datasette alpha release today. This adds basic alter table support API support, so you can request Datasette modify a table to add new columns needed for JSON objects submitted to the insert, upsert or update APIs.
It also makes some permission changes—fixing a minor bug with upsert permissions, and introducing a new rule where every permission plugin gets consulted for a permission check, with just one refusal vetoing that check.
