This enables cross-database SQL queries, including the ability to use joins and unions to combine data from tables that exist in different database files. See  Cross-database queries  for details. ( #283 ) \n                 \n                 \n                     --ssl-keyfile  and  --ssl-certfile  options can be used to specify a TLS certificate, allowing Datasette to serve traffic over  https://  without needing to run it behind a separate proxy. ( #1221 ) \n                 \n                 \n                     The  /:memory:  page has been renamed (and redirected) to  /_memory  for consistency with the new  /_internal  database introduced in Datasette 0.54. ( #1205 ) \n                 \n                 \n                     Added plugin testing documentation on  Using pdb for errors thrown inside Datasette . ( #1207 ) \n                 \n                 \n                     The  official Datasette Docker image  now uses Python 3.7.10, applying  the latest security fix  for that Python version.
