## Features

- Now tested against Python 3.11. Docker containers used by `datasette publish` and `datasette package` both now use that version of Python. ([#1853](https://github.com/simonw/datasette/issues/1853))
- `--load-extension` option now supports entrypoints. Thanks, Alex Garcia. ([#1789](https://github.com/simonw/datasette/pull/1789))
- Facet size can now be set per-table with the new `facet_size` table metadata option. ([#1804](https://github.com/simonw/datasette/issues/1804))
- The [truncate_cells_html](https://docs.datasette.io/en/stable/settings.html#setting-truncate-cells-html) setting now also affects long URLs in columns. ([#1805](https://github.com/simonw/datasette/issues/1805))
- The non-JavaScript SQL editor textarea now increases height to fit the SQL query. ([#1786](https://github.com/simonw/datasette/issues/1786))
- Facets are now displayed with better line-breaks in long values. Thanks, Daniel Rech. ([#1794](https://github.com/simonw/datasette/pull/1794))
- The `settings.json` file used in [Configuration directory mode](https://docs.datasette.io/en/stable/settings.html#config-dir) is now validated on startup. ([#1816](https://github.com/simonw/datasette/issues/1816))
- SQL queries can now include leading SQL comments, using `/* ... */` or `-- ...` syntax. Thanks, Charles Nepote. ([#1860](https://github.com/simonw/datasette/issues/1860))
- SQL query is now re-displayed when terminated with a time limit error. ([#1819](https://github.com/simonw/datasette/issues/1819))
- The [inspect data](https://docs.datasette.io/en/stable/performance.html#performance-inspect) mechanism is now used to speed up server startup - thanks, Forest Gregg. ([#1834](https://github.com/simonw/datasette/issues/1834))
- In [Configuration directory mode](https://docs.datasette.io/en/stable/settings.html#config-dir) databases with filenames ending in `.sqlite` or `.sqlite3` are now automatically added to the Datasette instance. ([#1646](https://github.com/simonw/datasette/issues/1646))
- Breadcrumb navigation display now respects the current user's permissions. ([#1831](https://github.com/simonw/datasette/issues/1831))

## Plugin hooks and internals

- The [prepare_jinja2_environment(env, datasette)](https://docs.datasette.io/en/stable/plugin_hooks.html#plugin-hook-prepare-jinja2-environment) plugin hook now accepts an optional `datasette` argument. Hook implementations can also now return an `async` function which will be awaited automatically. ([#1809](https://github.com/simonw/datasette/issues/1809))
- `Database(is_mutable=)` now defaults to `True`. ([#1808](https://github.com/simonw/datasette/issues/1808))
- The [datasette.check_visibility()](https://docs.datasette.io/en/stable/internals.html#datasette-check-visibility) method now accepts an optional `permissions=` list, allowing it to take multiple permissions into account at once when deciding if something should be shown as public or private. This has been used to correctly display padlock icons in more places in the Datasette interface. ([#1829](https://github.com/simonw/datasette/issues/1829))
- Datasette no longer enforces upper bounds on its dependencies. ([#1800](https://github.com/simonw/datasette/issues/1800))

## Documentation

- New tutorial: [Cleaning data with sqlite-utils and Datasette](https://datasette.io/tutorials/clean-data).
- Screenshots in the documentation are now maintained using [shot-scraper](https://shot-scraper.datasette.io/), as described in [Automating screenshots for the Datasette documentation using shot-scraper](https://simonwillison.net/2022/Oct/14/automating-screenshots/).

This can be used to sort a column in ascending or descending order, facet data by that column or filter the table to just rows that have a value for that column.

Plugin authors can use the new [datasette.client](https://docs.datasette.io/en/stable/internals.html#internals-datasette-client) object to make internal HTTP requests from their plugins, allowing them to make use of Datasette's JSON API. ([#943](https://github.com/simonw/datasette/issues/943))

Datasette's [metadata.json format](http://datasette.readthedocs.io/en/latest/metadata.html) 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](http://datasette.readthedocs.io/en/latest/sql_queries.html#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/>

  - Auto-link column values that look like URLs ([\#153](https://github.com/simonw/datasette/issues/153))

  - CSS styling hooks as classes on the body ([\#153](https://github.com/simonw/datasette/issues/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](https://github.com/simonw/datasette/issues/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 ...""
                    }
                }
            }
        }
    
    These will be shown in a new ""Queries"" section beneath ""Views"" on the database page.

  - New `datasette skeleton` command for generating `metadata.json` ([\#164](https://github.com/simonw/datasette/issues/164))

  - `metadata.json` support for per-table/per-database metadata ([\#165](https://github.com/simonw/datasette/issues/165))
    
    Also added support for descriptions and HTML descriptions.
    
    Here's an example metadata.json file illustrating custom per-database and per-table metadata:
    
        {
            ""title"": ""Overall datasette title"",
            ""description_html"": ""This is a <em>description with HTML</em>."",
            ""databases"": {
                ""db1"": {
                    ""title"": ""First database"",
                    ""description"": ""This is a string description & has no HTML"",
                    ""license_url"": ""http://example.com/"",
                ""license"": ""The example license"",
                    ""queries"": {
                      ""canned_query"": ""select * from table1 limit 3;""
                    },
                    ""tables"": {
                        ""table1"": {
                            ""title"": ""Custom title for table1"",
                            ""description"": ""Tables can have descriptions too"",
                            ""source"": ""This has a custom source"",
                            ""source_url"": ""http://example.com/""
                        }
                    }
                }
            }
        }

  - Renamed `datasette build` command to `datasette inspect` ([\#130](https://github.com/simonw/datasette/issues/130))

  - Upgrade to Sanic 0.7.0 ([\#168](https://github.com/simonw/datasette/issues/168))
    
    <https://github.com/channelcat/sanic/releases/tag/0.7.0>

  - Package and publish commands now accept `--static` and `--template-dir`
    
    Example usage:
    
        datasette package --static css:extra-css/ --static js:extra-js/ \
          sf-trees.db --template-dir templates/ --tag sf-trees --branch master
    
    This creates a local Docker image that includes copies of the templates/, extra-css/ and extra-js/ directories. You can then run it like this:
    
        docker run -p 8001:8001 sf-trees
    
    For publishing to Zeit now:
    
        datasette publish now --static css:extra-css/ --static js:extra-js/ \
          sf-trees.db --template-dir templates/ --name sf-trees --branch master

See [Datasette 1.0a2: Upserts and finely grained permissions](https://simonwillison.net/2022/Dec/15/datasette-1a2/) for an extended, annotated version of these release notes.

- New `/db/table/-/upsert` API, [documented here](https://docs.datasette.io/en/latest/json_api.html#tableupsertview). upsert is an update-or-insert: existing rows will have specified keys updated, but if no row matches the incoming primary key a brand new row will be inserted instead. ([#1878](https://github.com/simonw/datasette/issues/1878))
- New [register_permissions(datasette)](https://docs.datasette.io/en/latest/plugin_hooks.html#plugin-register-permissions) plugin hook. Plugins can now register named permissions, which will then be listed in various interfaces that show available permissions. ([#1940](https://github.com/simonw/datasette/issues/1940))
- The `/db/-/create` API for [creating a table](https://docs.datasette.io/en/latest/json_api.html#tablecreateview) now accepts `""ignore"": true` and `""replace"": true` options when called with the `""rows""` property that creates a new table based on an example set of rows. This means the API can be called multiple times with different rows, setting rules for what should happen if a primary key collides with an existing row. ([#1927](https://github.com/simonw/datasette/issues/1927))
- Arbitrary permissions can now be configured at the instance, database and resource (table, SQL view or canned query) level in Datasette's [Metadata](https://docs.datasette.io/en/latest/metadata.html#metadata) JSON and YAML files. The new `""permissions""` key can be used to specify which actors should have which permissions. See [Other permissions in metadata](https://docs.datasette.io/en/latest/authentication.html#authentication-permissions-other) for details. ([#1636](https://github.com/simonw/datasette/issues/1636))
- The `/-/create-token` page can now be used to create API tokens which are restricted to just a subset of actions, including against specific databases or resources. See [API Tokens](https://docs.datasette.io/en/latest/authentication.html#createtokenview) for details. ([#1947](https://github.com/simonw/datasette/issues/1947))
- Likewise, the [datasette create-token](https://docs.datasette.io/en/latest/internals.html#create-token-actor-id-expires-after-none-restrict-all-none-restrict-database-none-restrict-resource-none) CLI command can now create tokens with [a subset of permissions](https://docs.datasette.io/en/latest/authentication.html#authentication-cli-create-token-restrict).

For additional commentary on this release, see [Datasette 0.54, the annotated release notes](https://simonwillison.net/2021/Jan/25/datasette/).

### The _internal database

As part of ongoing work to help Datasette handle much larger numbers of connected databases and tables (see [Datasette Library](https://github.com/simonw/datasette/issues/417)) Datasette now maintains an in-memory SQLite database with details of all of the attached databases, tables, columns, indexes and foreign keys. ([#1150](https://github.com/simonw/datasette/issues/1150))

This will support future improvements such as a searchable, paginated homepage of all available tables.

You can explore an example of this database by [signing in as root](https://latest.datasette.io/login-as-root) to the `latest.datasette.io` demo instance and then navigating to [latest.datasette.io/_internal](https://latest.datasette.io/_internal).

Plugins can use these tables to introspect attached data in an efficient way. Plugin authors should note that this is not yet considered a stable interface, so any plugins that use this may need to make changes prior to Datasette 1.0 if the `_internal` table schemas change.

### Named in-memory database support

As part of the work building the `_internal` database, Datasette now supports named in-memory databases that can be shared across multiple connections. This allows plugins to create in-memory databases which will persist data for the lifetime of the Datasette server process. ([#1151](https://github.com/simonw/datasette/issues/1151))

The new `memory_name=` parameter to the [Database class](https://docs.datasette.io/en/stable/internals.html#internals-database) can be used to create named, shared in-memory databases.

### JavaScript modules

[JavaScript modules](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules) were introduced in ECMAScript 2015 and provide native browser support for the `import` and `export` keywords.

To use modules, JavaScript needs to be included in `<script>` tags with a `type=""module""` attribute.

Datasette now has the ability to output `<script type=""module"">` in places where you may wish to take advantage of modules. The `extra_js_urls` option described in [Custom CSS and JavaScript](https://docs.datasette.io/en/stable/custom_templates.html#customization-css-and-javascript) can now be used with modules, and module support is also available for the [extra_body_script()](https://docs.datasette.io/en/stable/plugin_hooks.html#plugin-hook-extra-body-script) plugin hook. ([#1186](https://github.com/simonw/datasette/issues/1186), [#1187](https://github.com/simonw/datasette/issues/1187))

[datasette-leaflet-freedraw](https://datasette.io/plugins/datasette-leaflet-freedraw) is the first example of a Datasette plugin that takes advantage of the new support for JavaScript modules. See [Drawing shapes on a map to query a SpatiaLite database](https://simonwillison.net/2021/Jan/24/drawing-shapes-spatialite/) for more on this plugin.

### Code formatting with Black and Prettier

Datasette adopted [Black](https://github.com/psf/black) for opinionated Python code formatting in June 2019. Datasette now also embraces [Prettier](https://prettier.io/) for JavaScript formatting, which like Black is enforced by tests in continuous integration. Instructions for using these two tools can be found in the new section on [Code formatting](https://docs.datasette.io/en/stable/contributing.html#contributing-formatting) in the contributors documentation. ([#1167](https://github.com/simonw/datasette/issues/1167))

### Other changes

-   Datasette can now open multiple database files with the same name, e.g. if you run `datasette path/to/one.db path/to/other/one.db`. ([#509](https://github.com/simonw/datasette/issues/509))
-   `datasette publish cloudrun` now sets `force_https_urls` for every deployment, fixing some incorrect `http://` links. ([#1178](https://github.com/simonw/datasette/issues/1178))
-   Fixed a bug in the example nginx configuration in [Running Datasette behind a proxy](https://docs.datasette.io/en/stable/deploying.html#deploying-proxy). ([#1091](https://github.com/simonw/datasette/issues/1091))

On authenticated Datasette instances (instances protected using plugins such as [datasette-auth-passwords](https://datasette.io/plugins/datasette-auth-passwords)) the API explorer interface could reveal the names of databases and tables within the protected instance. The data stored in those tables was not revealed.

For more information and workarounds, read [the security advisory](https://github.com/simonw/datasette/security/advisories/GHSA-7ch3-7pp7-7cpq). The issue has been present in every previous alpha version of Datasette 1.0: versions 1.0a0, 1.0a1, 1.0a2 and 1.0a3.

Also in this alpha:

- The new `datasette plugins --requirements` option outputs a list of currently installed plugins in Python `requirements.txt` format, useful for duplicating that installation elsewhere. ([#2133](https://github.com/simonw/datasette/issues/2133))
- [Writable canned queries](https://docs.datasette.io/en/latest/sql_queries.html#canned-queries-writable) can now define a `on_success_message_sql` field in their configuration, containing a SQL query that should be executed upon successful completion of the write operation in order to generate a message to be shown to the user. ([#2138](https://github.com/simonw/datasette/issues/2138))
- The automatically generated border color for a database is now shown in more places around the application. ([#2119](https://github.com/simonw/datasette/issues/2119))

The new [default JSON representation](https://docs.datasette.io/en/1.0a3/json_api.html#json-api-default) for both table pages (`/dbname/table.json`) and arbitrary SQL queries (`/dbname.json?sql=...`) is now shaped like this:
```json
{
  ""ok"": true,
  ""rows"": [
    {
      ""id"": 3,
      ""name"": ""Detroit""
    },
    {

    },
    {
      ""id"": 1,
      ""name"": ""San Francisco""
    }
  ],
  ""truncated"": false
}
```
Tables will include an additional `""next""` key for pagination, which can be passed to `?_next=` to fetch the next page of results.

The various `?_shape=` options continue to work as before - see [Different shapes](https://docs.datasette.io/en/1.0a3/json_api.html#json-api-shapes) for details.

A new `?_extra=` mechanism is available for tables, but has not yet been stabilized or documented. Details on that are available in [#262](https://github.com/simonw/datasette/issues/262).

### Smaller changes

- Datasette documentation now shows YAML examples for [Metadata](https://docs.datasette.io/en/1.0a3/metadata.html#metadata) by default, with a tab interface for switching to JSON. ([#1153](https://github.com/simonw/datasette/issues/1153))
- [register_output_renderer(datasette)](https://docs.datasette.io/en/1.0a3/plugin_hooks.html#plugin-register-output-renderer) plugins now have access to `error` and `truncated` arguments, allowing them to display error messages and take into account truncated results. ([#2130](https://github.com/simonw/datasette/issues/2130))
- `render_cell()` plugin hook now also supports an optional `request` argument. ([#2007](https://github.com/simonw/datasette/issues/2007))
- New `Justfile` to support development workflows for Datasette using [Just](https://github.com/casey/just).
- `datasette.render_template()` can now accepts a `datasette.views.Context` subclass as an alternative to a dictionary. ([#2127](https://github.com/simonw/datasette/issues/2127))
- `datasette install -e path` option for editable installations, useful while developing plugins. ([#2106](https://github.com/simonw/datasette/issues/2106))
- When started with the `--cors` option Datasette now serves an `Access-Control-Max-Age: 3600` header, ensuring CORS OPTIONS requests are repeated no more than once an hour. ([#2079](https://github.com/simonw/datasette/issues/2079))
- Fixed a bug where the `_internal` database could display `None` instead of `null` for in-memory databases.

Previously, API tokens have only been supported by installing additional plugins.

This is very much a preview: expect many more backwards incompatible API changes prior to the full 1.0 release.

Feedback enthusiastically welcomed, either through [issue comments](https://github.com/simonw/datasette/issues/1850) or via the [Datasette Discord](https://datasette.io/discord) community.

### Signed API tokens

- New `/-/create-token` page allowing authenticated users to create signed API tokens that can act on their behalf, see [API Tokens](https://docs.datasette.io/en/1.0-dev/authentication.html#createtokenview). ([#1852](https://github.com/simonw/datasette/issues/1852))
- New `datasette create-token` command for creating tokens from the command line: [datasette create-token](https://docs.datasette.io/en/1.0-dev/authentication.html#authentication-cli-create-token).
- New [allow_signed_tokens](https://docs.datasette.io/en/1.0-dev/settings.html#setting-allow-signed-tokens) setting which can be used to turn off signed token support. ([#1856](https://github.com/simonw/datasette/issues/1856))
- New [max_signed_tokens_ttl](https://docs.datasette.io/en/1.0-dev/settings.html#setting-max-signed-tokens-ttl) setting for restricting the maximum allowed duration of a signed token. ([#1858](https://github.com/simonw/datasette/issues/1858))

### Write API

- New API explorer at `/-/api` for trying out the API. ([#1871](https://github.com/simonw/datasette/issues/1871))
- `/db/-/create` API for [Creating a table](https://docs.datasette.io/en/1.0-dev/json_api.html#tablecreateview). ([#1882](https://github.com/simonw/datasette/issues/1882))

- Initial documentation for plugins, closes [#213](https://github.com/simonw/datasette/issues/213)

  https://datasette.readthedocs.io/en/latest/plugins.html

- New `--plugins-dir=plugins/` option ([#212](https://github.com/simonw/datasette/issues/212))

  New option causing Datasette to load and evaluate all of the Python files in the specified directory and register any plugins that are defined in those files.

  This new option is available for the following commands:

      datasette serve mydb.db --plugins-dir=plugins/
      datasette publish now/heroku mydb.db --plugins-dir=plugins/
      datasette package mydb.db --plugins-dir=plugins/

- Start of the plugin system, based on pluggy ([#210](https://github.com/simonw/datasette/issues/14))

  Uses https://pluggy.readthedocs.io/ originally created for the py.test project

  We're starting with two plugin hooks:

  `prepare_connection(conn)`

  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.

  An example plugin which uses these two hooks can be found at https://github.com/simonw/datasette-plugin-demos or installed using `pip install datasette-plugin-demos`

-   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](https://github.com/simonw/datasette/issues/992))
-   The `/-/config` introspection page is now `/-/settings`, and the previous page redirects to the new one. ([#1103](https://github.com/simonw/datasette/issues/1103))
-   The `config.json` file in [Configuration directory mode](https://docs.datasette.io/en/stable/settings.html#config-dir) is now called `settings.json`. ([#1104](https://github.com/simonw/datasette/issues/1104))
-   The undocumented `datasette.config()` internal method has been replaced by a documented [.setting(key)](https://docs.datasette.io/en/stable/internals.html#datasette-setting) method. ([#1107](https://github.com/simonw/datasette/issues/1107))

Also in this release:

-   New plugin hook: [database_actions(datasette, actor, database)](https://docs.datasette.io/en/stable/plugin_hooks.html#plugin-hook-database-actions), which adds menu items to a new cog menu shown at the top of the database page. ([#1077](https://github.com/simonw/datasette/issues/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.

-   Swept the documentation to remove words that minimize involved difficulty. ([#1089](https://github.com/simonw/datasette/issues/1089))

And some bug fixes:

-   Foreign keys linking to rows with blank label columns now display as a hyphen, allowing those links to be clicked. ([#1086](https://github.com/simonw/datasette/issues/1086))
-   Fixed bug where row pages could sometimes 500 if the underlying queries exceeded a time limit. ([#1088](https://github.com/simonw/datasette/issues/1088))

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](https://wtr-api.herokuapp.com/wtr-663ea99/license_frequency?frequency__gt=50GHz&height__lt=50ft).

  - Link foreign keys which don't have labels. \[Russ Garrett\]
    
    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.
      - Print tracebacks to console when handling 500 errors.

  - Fix SQLite error when loading rows with no incoming FKs. \[Russ Garrett\]
    
    This fixes `ERROR: conn=<sqlite3.Connection object at 0x10bbb9f10>, sql = 'select ', params = {'id': '1'}` caused by an invalid query when loading incoming FKs.

-   SQLite [PRAGMA functions](https://www.sqlite.org/pragma.html#pragfunc) such as `pragma_table_info(tablename)` are now allowed in Datasette SQL queries. (#761)
-   Datasette pages now consistently return a `content-type` of `text/html; charset=utf-8""`. (#752)
-   Datasette now handles an ASGI `raw_path` value of `None`, which should allow compatibilty with the [Mangum](https://github.com/erm/mangum) adapter for running ASGI apps on AWS Lambda. Thanks, Colin Dellow. (#719)
