( #2101 ) 
                 The only alter operation supported so far is adding new columns to an existing table. 
                 
                     
                         The  /db/-/create  API now adds new columns during large operations to create a table based on incoming example  ""rows"" , in the case where one of the later rows includes columns that were not present in the earlier batches. This requires the  create-table  but not the  alter-table  permission. 
                     
                     
                         When  /db/-/create  is called with rows in a situation where the table may have been already created, an  ""alter"": true  key can be included to indicate that any missing columns from the new rows should be added to the table. This requires the  alter-table  permission. 
                     
                     
                         /db/table/-/insert  and  /db/table/-/upsert  and  /db/table/row-pks/-/update  all now also accept  ""alter"": true , depending on the  alter-table  permission.

changelog:asgi,changelog,asgi,ASGI,"ASGI  is the Asynchronous Server Gateway Interface standard. I've been wanting to convert Datasette into an ASGI application for over a year -  Port Datasette to ASGI #272  tracks thirteen months of intermittent development - but with Datasette 0.29 the change is finally released.

changelog:authentication,changelog,authentication,Authentication,"Prior to this release the Datasette ecosystem has treated authentication as exclusively the realm of plugins, most notably through  datasette-auth-github . 
                 0.44 introduces  Authentication and permissions  as core Datasette concepts ( #699 ). This enables different plugins to share responsibility for authenticating requests - you might have one plugin that handles user accounts and another one that allows automated access via API keys, for example. 
                 You'll need to install plugins if you want full user accounts, but default Datasette can now authenticate a single root user with the new  --root  command-line option, which outputs a one-time use URL to  authenticate as a root actor  ( #784 ):

    latitude_column: xlat
    longitude_column: xlon 
                         Previously plugins were configured in  metadata.yaml , which was confusing as plugin settings were unrelated to database and table metadata. 
                     
                     
                         The  -s/--setting  option can now be used to set plugin configuration as well. See  Configuration via the command-line  for details. ( #2252 )

                         Existing Datasette installations may already have configuration set in  metadata.yaml  that should be migrated to  datasette.yaml .

                     This is called when a new SQLite connection is created. It can be used to register custom SQL functions. 
                     prepare_jinja2_environment(env) 
                     This is called with the Jinja2 environment. It can be used to register custom template tags and filters.

                contributed by Russ Garrett ( #203 ).
                You can now optionally specify the units for specific columns using  metadata.json .
                Once specified, units will be displayed in the HTML view of your table. They also become
                available for use in filters - if a column is configured with a unit of distance, you can
                request all rows where that column is less than 50 meters or more than 20 feet for example.

                     This renders unlabeled FKs as simple links. 
                     Also includes bonus fixes for two minor issues: 
                     
                         
                             In foreign key link hrefs the primary key was escaped using HTML
                                escaping rather than URL escaping. This broke some non-integer PKs.

changelog:id177,changelog,id177,0.14 (2017-12-09),"The theme of this release is customization: Datasette now allows every aspect
                of its presentation  to be customized 
                either using additional CSS or by providing entirely new templates. 
             Datasette's  metadata.json format 
                has also been expanded, to allow per-database and per-table metadata. A new
                 datasette skeleton  command can be used to generate a skeleton JSON file
                ready to be filled in with per-database and per-table details. 
             The  metadata.json  file can also be used to define
                 canned queries ,
                as a more powerful alternative to SQL views. 
             
                 
                     extra_css_urls / extra_js_urls  in metadata 
                     A mechanism in the  metadata.json  format for adding custom CSS and JS urls. 
                     Create a  metadata.json  file that looks like this: 
                     {
    ""extra_css_urls"": [
        ""https://simonwillison.net/static/css/all.bf8cd891642c.css""
    ],
    ""extra_js_urls"": [
        ""https://code.jquery.com/jquery-3.2.1.slim.min.js""
    ]
} 
                     Then start datasette like this: 
                     datasette mydb.db --metadata=metadata.json 
                     The CSS and JavaScript files will be linked in the  <head>  of every page. 
                     You can also specify a SRI (subresource integrity hash) for these assets: 
                     {
    ""extra_css_urls"": [
        {
            ""url"": ""https://simonwillison.net/static/css/all.bf8cd891642c.css"",
            ""sri"": ""sha384-9qIZekWUyjCyDIf2YK1FRoKiPJq4PHt6tp/ulnuuyRBvazd0hG7pWbE99zvwSznI""
        }
    ],
    ""extra_js_urls"": [
        {
            ""url"": ""https://code.jquery.com/jquery-3.2.1.slim.min.js"",
            ""sri"": ""sha256-k2WSCIexGzOj3Euiig+TlR8gA0EmPjuc79OEeY5L45g=""
        }
    ]
} 
                     Modern browsers will only execute the stylesheet or JavaScript if the SRI hash
                        matches the content served. You can generate hashes using  https://www.srihash.org/

                     CSS styling hooks as classes on the body ( #153 ) 
                     Every template now gets CSS classes in the body designed to support custom
                        styling. 
                     The index template (the top level page at  / ) gets this: 
                     <body class=""index""> 
                     The database template ( /dbname/ ) gets this: 
                     <body class=""db db-dbname""> 
                     The table template ( /dbname/tablename ) gets: 
                     <body class=""table db-dbname table-tablename""> 
                     The row template ( /dbname/tablename/rowid ) gets: 
                     <body class=""row db-dbname table-tablename""> 
                     The  db-x  and  table-x  classes use the database or table names themselves IF
                        they are valid CSS identifiers. If they aren't, we strip any invalid
                        characters out and append a 6 character md5 digest of the original name, in
                        order to ensure that multiple tables which resolve to the same stripped
                        character version still have different CSS classes. 
                     Some examples (extracted from the unit tests): 
                     ""simple"" => ""simple""
""MixedCase"" => ""MixedCase""
""-no-leading-hyphens"" => ""no-leading-hyphens-65bea6""
""_no-leading-underscores"" => ""no-leading-underscores-b921bc""
""no spaces"" => ""no-spaces-7088d7""
""-"" => ""336d5e""
""no $ characters"" => ""no--characters-59e024"" 
                 
                 
                     datasette --template-dir=mytemplates/  argument 
                     You can now pass an additional argument specifying a directory to look for
                        custom templates in. 
                     Datasette will fall back on the default templates if a template is not
                        found in that directory. 
                 
                 
                     Ability to over-ride templates for individual tables/databases. 
                     It is now possible to over-ride templates on a per-database / per-row or per-
                        table basis. 
                     When you access e.g.  /mydatabase/mytable  Datasette will look for the following: 
                     - table-mydatabase-mytable.html
- table.html 
                     If you provided a  --template-dir  argument to datasette serve it will look in
                        that directory first. 
                     The lookup rules are as follows: 
                     Index page (/):
    index.html

Database page (/mydatabase):
    database-mydatabase.html
    database.html

Table page (/mydatabase/mytable):
    table-mydatabase-mytable.html
    table.html

Row page (/mydatabase/mytable/id):
    row-mydatabase-mytable.html
    row.html 
                     If a table name has spaces or other unexpected characters in it, the template
                        filename will follow the same rules as our custom  <body>  CSS classes
                        - for example, a table called ""Food Trucks""
                        will attempt to load the following templates: 
                     table-mydatabase-Food-Trucks-399138.html
table.html 
                     It is possible to extend the default templates using Jinja template
                        inheritance. If you want to customize EVERY row template with some additional
                        content you can do so by creating a row.html template like this: 
                     {% extends ""default:row.html"" %}

{% block content %}
<h1>EXTRA HTML AT THE TOP OF THE CONTENT BLOCK</h1>
<p>This line renders the original block:</p>
{{ super() }}
{% endblock %} 
                 
                 
                     --static  option for datasette serve ( #160 ) 
                     You can now tell Datasette to serve static files from a specific location at a
                        specific mountpoint. 
                     For example: 
                     datasette serve mydb.db --static extra-css:/tmp/static/css 
                     Now if you visit this URL: 
                     http://localhost:8001/extra-css/blah.css 
                     The following file will be served: 
                     /tmp/static/css/blah.css 
                 
                 
                     Canned query support. 
                     Named canned queries can now be defined in  metadata.json  like this: 
                     {
    ""databases"": {
        ""timezones"": {
            ""queries"": {
                ""timezone_for_point"": ""select tzid from timezones ...""
            }
        }

                     Initial implementation of  ?_group_count=column . 
                     URL shortcut for counting rows grouped by one or more columns. 
                     ?_group_count=column1&_group_count=column2  works as well. 
                     SQL generated looks like this: 
                     select ""qSpecies"", count(*) as ""count""
from Street_Tree_List
group by ""qSpecies""

                     Added  --build=master  option to datasette publish and package. 
                     The  datasette publish  and  datasette package  commands both now accept an
                        optional  --build  argument. If provided, this can be used to specify a branch
                        published to GitHub that should be built into the container. 
                     This makes it easier to test code that has not yet been officially released to
                        PyPI, e.g.: 
                     datasette publish now mydb.db --branch=master

                     Table views now show expanded foreign key references, if possible. 
                     If a table has foreign key columns, and those foreign key tables have
                         label_columns , the TableView will now query those other tables for the
                        corresponding values and display those values as links in the corresponding
                        table cells. 
                     label_columns are currently detected by the  inspect()  function, which looks
                        for any table that has just two columns - an ID column and one other - and
                        sets the  label_column  to be that second non-ID column.

changelog:id21,changelog,id21,0.61 (2022-03-23),"In preparation for Datasette 1.0, this release includes two potentially backwards-incompatible changes. Hashed URL mode has been moved to a separate plugin, and the way Datasette generates URLs to databases and tables with special characters in their name such as  /  and  .  has changed. 
             Datasette also now requires Python 3.7 or higher. 
             
                 
                     URLs within Datasette now use a different encoding scheme for tables or databases that include ""special"" characters outside of the range of  a-zA-Z0-9_- . This scheme is explained here:  Tilde encoding . ( #1657 ) 
                 
                 
                     Removed hashed URL mode from Datasette. The new  datasette-hashed-urls  plugin can be used to achieve the same result, see  datasette-hashed-urls  for details. ( #1661 ) 
                 
                 
                     Databases can now have a custom path within the Datasette instance that is independent of the database name, using the  db.route  property. ( #1668 ) 
                 
                 
                     Datasette is now covered by a  Code of Conduct . ( #1654 ) 
                 
                 
                     Python 3.6 is no longer supported. ( #1577 ) 
                 
                 
                     Tests now run against Python 3.11-dev. ( #1621 ) 
                 
                 
                     New  datasette.ensure_permissions(actor, permissions)  internal method for checking multiple permissions at once. ( #1675 ) 
                 
                 
                     New  datasette.check_visibility(actor, action, resource=None)  internal method for checking if a user can see a resource that would otherwise be invisible to unauthenticated users. ( #1678 ) 
                 
                 
                     Table and row HTML pages now include a  <link rel=""alternate"" type=""application/json+datasette"" href=""..."">  element and return a  Link: URL; rel=""alternate""; type=""application/json+datasette""  HTTP header pointing to the JSON version of those pages. ( #1533 ) 
                 
                 
                     Access-Control-Expose-Headers: Link  is now added to the CORS headers, allowing remote JavaScript to access that header. 
                 
                 
                     Canned queries are now shown at the top of the database page, directly below the SQL editor. Previously they were shown at the bottom, below the list of tables. ( #1612 ) 
                 
                 
                     Datasette now has a default favicon. ( #1603 ) 
                 
                 
                     sqlite_stat  tables are now hidden by default. ( #1587 ) 
                 
                 
                     SpatiaLite tables  data_licenses ,  KNN  and  KNN2  are now hidden by default. ( #1601 ) 
                 
                 
                     SQL query tracing mechanism now works for queries executed in  asyncio  sub-tasks, such as those created by  asyncio.gather() . ( #1576 ) 
                 
                 
                     datasette.tracer  mechanism is now documented. 
                 
                 
                     Common Datasette symbols can now be imported directly from the top-level  datasette  package, see  Import shortcuts . Those symbols are  Response ,  Forbidden ,  NotFound ,  hookimpl ,  actor_matches_allow . ( #957 ) 
                 
                 
                     /-/versions  page now returns additional details for libraries used by SpatiaLite. ( #1607 ) 
                 
                 
                     Documentation now links to the  Datasette Tutorials . 
                 
                 
                     Datasette will now also look for SpatiaLite in  /opt/homebrew  - thanks, Dan Peterson. ( #1649 )

                     If someone executes 'select * from table' against a table with a million rows
                        in it, we could run into problems: just serializing that much data as JSON is
                        likely to lock up the server. 
                     Solution: we now have a hard limit on the maximum number of rows that can be
                        returned by a query. If that limit is exceeded, the server will return a
                         ""truncated"": true  field in the JSON. 
                     This limit can be optionally controlled by the new  --max_returned_rows 
                        option.

changelog:id46,changelog,id46,0.52 (2020-11-28),"This release includes a number of changes relating to an internal rebranding effort: Datasette's  configuration  mechanism (things like  datasette --config default_page_size:10 ) has been renamed to  settings . 
             
                 
                     New  --setting default_page_size 10  option as a replacement for  --config default_page_size:10  (note the lack of a colon). The  --config  option is deprecated but will continue working until Datasette 1.0. ( #992 )

                     New plugin hook:  database_actions(datasette, actor, database, request) , which adds menu items to a new cog menu shown at the top of the database page. ( #1077 ) 
                 
                 
                     datasette publish cloudrun  has a new  --apt-get-install  option that can be used to install additional Ubuntu packages as part of the deployment. This is useful for deploying the new  datasette-ripgrep plugin . ( #1110 )

                     Visually distinguish float and integer columns - useful for figuring out why order-by-column might be returning unexpected results. ( #729 ) 
                 
                 
                     The  Request object , which is passed to several plugin hooks, is now documented. ( #706 ) 
                 
                 
                     New  metadata.json  option for setting a custom default page size for specific tables and views, see  Setting a custom page size . ( #751 ) 
                 
                 
                     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 ) 
                 
                 
                     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 ) 
                 
                 
                     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.
