( #581 ,  #770 ) \n                 \n                 \n                     Visually distinguish float and integer columns - useful for figuring out why order-by-column might be returning unexpected results. ( #729 ) \n                 \n                 \n                     The  Request object , which is passed to several plugin hooks, is now documented. ( #706 ) \n                 \n                 \n                     New  metadata.json  option for setting a custom default page size for specific tables and views, see  Setting a custom page size . ( #751 ) \n                 \n                 \n                     Canned queries can now be configured with a default URL fragment hash, useful when working with plugins such as  datasette-vega , see  Additional canned query options . ( #706 ) \n                 \n                 \n                     Fixed a bug in  datasette publish  when running on operating systems where the  /tmp  directory lives in a different volume, using a backport of the Python 3.8  shutil.copytree()  function. ( #744 ) \n                 \n                 \n                     Every plugin hook is now covered by the unit tests, and a new unit test checks that each plugin hook has at least one corresponding test.
