( #2277 ) \n             \n                 \n                     The  database.execute_write_fn()  method has a new  transaction=True  parameter. This defaults to  True  which means all functions executed using this method are now automatically wrapped in a transaction - previously the functions needed to roll transaction handling on their own, and many did not. \n                 \n                 \n                     Pass  transaction=False  to  execute_write_fn()  if you want to manually handle transactions in your function. \n                 \n                 \n                     Several internal Datasette features, including parts of the  JSON write API , had been failing to wrap their operations in a transaction. This has been fixed by the new  transaction=True  default.", "breadcrumbs": "[\"Changelog\"]", "references": "[{\"href\": \"https://github.com/simonw/datasette/issues/2277\", \"label\": \"#2277\"}]"}
