This mechanism is intended to be used by plugins that may need to display the actor who was responsible for something managed by that plugin: they can now resolve the recorded IDs of actors into the full actor objects. ([#2181](https://github.com/simonw/datasette/issues/2181))
- `DATASETTE_LOAD_PLUGINS` environment variable for [controlling which plugins](https://docs.datasette.io/en/latest/plugins.html#plugins-datasette-load-plugins) are loaded by Datasette. ([#2164](https://github.com/simonw/datasette/issues/2164))
- Datasette now checks if the user has permission to view a table linked to by a foreign key before turning that foreign key into a clickable link. ([#2178](https://github.com/simonw/datasette/issues/2178))
- The `execute-sql` permission now implies that the actor can also view the database and instance. ([#2169](https://github.com/simonw/datasette/issues/2169))
- Documentation describing a pattern for building plugins that themselves [define further hooks](https://docs.datasette.io/en/latest/writing_plugins.html#writing-plugins-extra-hooks) for other plugins. ([#1765](https://github.com/simonw/datasette/issues/1765))

Previously you needed to create a token with restrictions that explicitly listed `view-instance` and `view-database` and `view-table` in order to view a table without getting a permission denied error. ([#2102](https://github.com/simonw/datasette/issues/2102))
- New `datasette.yaml` (or `.json`) configuration file, which can be specified using `datasette -c path-to-file`. The goal here to consolidate settings, plugin configuration, permissions, canned queries, and other Datasette configuration into a single single file, separate from `metadata.yaml`. The legacy `settings.json` config file used for [Configuration directory mode](https://docs.datasette.io/en/1.0a5/settings.html#config-dir) has been removed, and `datasette.yaml` has a `""settings""` section where the same settings key/value pairs can be included. In the next future alpha release, more configuration such as plugins/permissions/canned queries will be moved to the `datasette.yaml` file. See [#2093](https://github.com/simonw/datasette/issues/2093) for more details. Thanks, Alex Garcia.
- The `-s/--setting` option can now take dotted paths to nested settings. These will then be used to set or over-ride the same options as are present in the new configuration file. ([#2156](https://github.com/simonw/datasette/issues/2156))
- New `--actor '{""id"": ""json-goes-here""}'` option for use with `datasette --get` to treat the simulated request as being made by a specific actor, see [datasette --get](https://docs.datasette.io/en/1.0a5/cli-reference.html#cli-datasette-get). ([#2153](https://github.com/simonw/datasette/issues/2153))
- The Datasette `_internal` database has had some changes. It no longer shows up in the `datasette.databases` list by default, and is now instead available to plugins using the `datasette.get_internal_database()`. Plugins are invited to use this as a private database to store configuration and settings and secrets that should not be made visible through the default Datasette interface. Users can pass the new `--internal internal.db` option to persist that internal database to disk. Thanks, Alex Garcia. ([#2157](https://github.com/simonw/datasette/issues/2157)).",107914493,

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))
- Every instance of example shell script code in the documentation should now include a working copy button, free from additional syntax.

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"": 2,
      ""name"": ""Los Angeles""
    },
    {
      ""id"": 4,
      ""name"": ""Memnonia""
    },
    {
      ""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.

SpatiaLite includes SQL functions that could cause the Datasette server to crash. See [SpatiaLite](https://docs.datasette.io/en/stable/spatialite.html#spatialite) for more details.
- New [default_allow_sql](https://docs.datasette.io/en/stable/settings.html#setting-default-allow-sql) setting, providing an easier way to disable all arbitrary SQL execution by end users: `datasette --setting default_allow_sql off`. See also [Controlling the ability to execute arbitrary SQL](https://docs.datasette.io/en/stable/authentication.html#authentication-permissions-execute-sql).

- You no longer need to ensure `await datasette.invoke_startup()` has been called in order for Datasette to start correctly serving requests - this is now handled automatically the first time the server receives a request. This fixes a bug experienced when Datasette is served directly by an ASGI application server such as Uvicorn or Gunicorn.

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.

- The <https://latest.datasette.io/> demo instance now includes an `ephemeral` database which can be used to test Datasette's write APIs, using the new [datasette-ephemeral-tables](https://datasette.io/plugins/datasette-ephemeral-tables) plugin to drop any created tables after five minutes. This database is only available if you sign in as the root user using the link on the homepage. ([#1915](https://github.com/simonw/datasette/issues/1915))

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))

## 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))

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.

See also the [annotated release notes](https://simonwillison.net/2022/Mar/24/datasette-061/).

-   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](https://docs.datasette.io/en/stable/internals.html#internals-tilde-encoding). ([#1657](https://github.com/simonw/datasette/issues/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](https://docs.datasette.io/en/stable/performance.html#performance-hashed-urls) for details. ([#1661](https://github.com/simonw/datasette/issues/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](https://github.com/simonw/datasette/issues/1668))
-   Datasette is now covered by a [Code of Conduct](https://github.com/simonw/datasette/blob/main/CODE_OF_CONDUCT.md). ([#1654](https://github.com/simonw/datasette/issues/1654))
-   Python 3.6 is no longer supported. ([#1577](https://github.com/simonw/datasette/issues/1577))
-   Tests now run against Python 3.11-dev. ([#1621](https://github.com/simonw/datasette/issues/1621))
-   New [datasette.ensure_permissions(actor, permissions)](https://docs.datasette.io/en/stable/internals.html#datasette-ensure-permissions) internal method for checking multiple permissions at once. ([#1675](https://github.com/simonw/datasette/issues/1675))
-   New [datasette.check_visibility(actor, action, resource=None)](https://docs.datasette.io/en/stable/internals.html#datasette-check-visibilty) internal method for checking if a user can see a resource that would otherwise be invisible to unauthenticated users. ([#1678](https://github.com/simonw/datasette/issues/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](https://github.com/simonw/datasette/issues/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](https://github.com/simonw/datasette/issues/1612))
-   Datasette now has a default favicon. ([#1603](https://github.com/simonw/datasette/issues/1603))
-   `sqlite_stat` tables are now hidden by default. ([#1587](https://github.com/simonw/datasette/issues/1587))
-   SpatiaLite tables `data_licenses`, `KNN` and `KNN2` are now hidden by default. ([#1601](https://github.com/simonw/datasette/issues/1601))

-   New plugin hook: [filters_from_request(request, database, table, datasette)](https://docs.datasette.io/en/stable/plugin_hooks.html#plugin-hook-filters-from-request), which runs on the table page and can be used to support new custom query string parameters that modify the SQL query. ([#473](https://github.com/simonw/datasette/issues/473))
-   Added two additional methods for writing to the database: [await db.execute_write_script(sql, block=True)](https://docs.datasette.io/en/stable/internals.html#database-execute-write-script) and [await db.execute_write_many(sql, params_seq, block=True)](https://docs.datasette.io/en/stable/internals.html#database-execute-write-many). ([#1570](https://github.com/simonw/datasette/issues/1570))
-   The [db.execute_write()](https://docs.datasette.io/en/stable/internals.html#database-execute-write) internal method now defaults to blocking until the write operation has completed. Previously it defaulted to queuing the write and then continuing to run code while the write was in the queue. ([#1579](https://github.com/simonw/datasette/issues/1579))
-   Database write connections now execute the [prepare_connection(conn, database, datasette)](https://docs.datasette.io/en/stable/plugin_hooks.html#plugin-hook-prepare-connection) plugin hook. ([#1564](https://github.com/simonw/datasette/issues/1564))
-   The `Datasette()` constructor no longer requires the `files=` argument, and is now documented at [Datasette class](https://docs.datasette.io/en/stable/internals.html#internals-datasette). ([#1563](https://github.com/simonw/datasette/issues/1563))
-   The tracing feature now traces write queries, not just read queries. ([#1568](https://github.com/simonw/datasette/issues/1568))
-   The query string variables exposed by `request.args` will now include blank strings for arguments such as `foo` in `?foo=&bar=1` rather than ignoring those parameters entirely. ([#1551](https://github.com/simonw/datasette/issues/1551))

### Faceting

-   The number of unique values in a facet is now always displayed. Previously it was only displayed if the user specified `?_facet_size=max`. ([#1556](https://github.com/simonw/datasette/issues/1556))
-   Facets of type `date` or `array` can now be configured in `metadata.json`, see [Facets in metadata.json](https://docs.datasette.io/en/stable/facets.html#facets-metadata). Thanks, David Larlet. ([#1552](https://github.com/simonw/datasette/issues/1552))
-   New `?_nosuggest=1` parameter for table views, which disables facet suggestion. ([#1557](https://github.com/simonw/datasette/issues/1557))
-   Fixed bug where `?_facet_array=tags&_facet=tags` would only display one of the two selected facets. ([#625](https://github.com/simonw/datasette/issues/625))

### Other small fixes

-   Made several performance improvements to the database schema introspection code that runs when Datasette first starts up. ([#1555](https://github.com/simonw/datasette/issues/1555))
-   Label columns detected for foreign keys are now case-insensitive, so `Name` or `TITLE` will be detected in the same way as `name` or `title`. ([#1544](https://github.com/simonw/datasette/issues/1544))
-   Upgraded Pluggy dependency to 1.0. ([#1575](https://github.com/simonw/datasette/issues/1575))

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))
-   The [Datasette Ecosystem](https://docs.datasette.io/en/stable/ecosystem.html#ecosystem) documentation page has been reduced in size in favour of the `datasette.io` [tools](https://datasette.io/tools) and [plugins](https://datasette.io/plugins) directories. ([#1182](https://github.com/simonw/datasette/issues/1182))
-   The request object now provides a `request.full_path` property, which returns the path including any query string. ([#1184](https://github.com/simonw/datasette/issues/1184))

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.

### New visual design

Datasette is no longer white and grey with blue and purple links! [Natalie Downe](https://twitter.com/natbat) has been working on a visual refresh, the first iteration of which is included in this release. ([#1056](https://github.com/simonw/datasette/pull/1056))

![datasette-0 51](https://user-images.githubusercontent.com/9599/97791267-d9011e80-1b8d-11eb-9b1b-42908266f36f.png)

### Plugins can now add links within Datasette

A number of existing Datasette plugins add new pages to the Datasette interface, providig tools for things like [uploading CSVs](https://github.com/simonw/datasette-upload-csvs), [editing table schemas](https://github.com/simonw/datasette-edit-schema) or [configuring full-text search](https://github.com/simonw/datasette-configure-fts).

Plugins like this can now link to themselves from other parts of Datasette interface. The [menu_links(datasette, actor)](https://docs.datasette.io/en/stable/plugin_hooks.html#plugin-hook-menu-links) hook ([#1064](https://github.com/simonw/datasette/issues/1064)) lets plugins add links to Datasette's new top-right application menu, and the [table_actions(datasette, actor, database, table)](https://docs.datasette.io/en/stable/plugin_hooks.html#plugin-hook-table-actions) hook ([#1066](https://github.com/simonw/datasette/issues/1066)) adds links to a new ""table actions"" menu on the table page.

The demo at [latest.datasette.io](https://latest.datasette.io/) now includes some example plugins. To see the new table actions menu first [sign into that demo as root](https://latest.datasette.io/login-as-root) and then visit the [facetable](https://latest.datasette.io/fixtures/facetable) table to see the new cog icon menu at the top of the page.

### Binary data

SQLite tables can contain binary data in `BLOB` columns. Datasette now provides links for users to download this data directly from Datasette, and uses those links to make binary data available from CSV exports. See [Binary data](https://docs.datasette.io/en/stable/binary_data.html#binary) for more details. ([#1036](https://github.com/simonw/datasette/issues/1036) and [#1034](https://github.com/simonw/datasette/issues/1034)).

### URL building

The new [datasette.urls](https://docs.datasette.io/en/stable/internals.html#internals-datasette-urls) family of methods can be used to generate URLs to key pages within the Datasette interface, both within custom templates and Datasette plugins. See [Building URLs within plugins](https://docs.datasette.io/en/stable/writing_plugins.html#writing-plugins-building-urls) for more details. ([#904](https://github.com/simonw/datasette/issues/904))

### Running Datasette behind a proxy

The [base_url](https://docs.datasette.io/en/stable/config.html#config-base-url) configuration option is designed to help run Datasette on a specific path behind a proxy - for example if you want to run an instance of Datasette at `/my-datasette/` within your existing site's URL hierarchy, proxied behind nginx or Apache.

Support for this configuration option has been greatly improved ([#1023](https://github.com/simonw/datasette/issues/1023)), and guidelines for using it are now available in a new documentation section on [Running Datasette behind a proxy](https://docs.datasette.io/en/stable/deploying.html#deploying-proxy). ([#1027](https://github.com/simonw/datasette/issues/1027))

### Smaller changes

- Wide tables shown within Datasette now scroll horizontally ([#998](https://github.com/simonw/datasette/issues/998)). This is achieved using a new `<div class=""table-wrapper"">` element which may impact the implementation of some plugins (for example [this change to datasette-cluster-map](https://github.com/simonw/datasette-cluster-map/commit/fcb4abbe7df9071c5ab57defd39147de7145b34e)).

### Magic parameters for canned queries

Canned queries now support [Magic parameters](https://docs.datasette.io/en/stable/sql_queries.html#canned-queries-magic-parameters), which can be used to insert or select automatically generated values. For example:
```sql
insert into logs
  (user_id, timestamp)
values
  (:_actor_id, :_now_datetime_utc)
```
This inserts the currently authenticated actor ID and the current datetime. ([#842](https://github.com/simonw/datasette/issues/842))

### Log out

The [ds_actor cookie](https://docs.datasette.io/en/stable/authentication.html#authentication-ds-actor) can be used by plugins (or by Datasette's [--root mechanism](https://docs.datasette.io/en/stable/authentication.html#authentication-root)) to authenticate users. The new `/-/logout` page provides a way to clear that cookie.

A ""Log out"" button now shows in the global navigation provided the user is authenticated using the `ds_actor` cookie. ([#840](https://github.com/simonw/datasette/issues/840))

### Better plugin documentation

The plugin documentation has been re-arranged into four sections, including a brand new section on testing plugins. ([#687](https://github.com/simonw/datasette/issues/687))

-   [Plugins](https://docs.datasette.io/en/stable/plugins.html#plugins) introduces Datasette's plugin system and describes how to install and configure plugins.
-   [Writing plugins](https://docs.datasette.io/en/stable/writing_plugins.html#writing-plugins) describes how to author plugins, from simple one-off plugins to packaged plugins that can be published to PyPI. It also describes how to start a plugin using the new [datasette-plugin](https://github.com/simonw/datasette-plugin) cookiecutter template.
-   [Plugin hooks](https://docs.datasette.io/en/stable/plugin_hooks.html#plugin-hooks) is a full list of detailed documentation for every Datasette plugin hook.
-   [Testing plugins](https://docs.datasette.io/en/stable/testing_plugins.html#testing-plugins) describes how to write tests for Datasette plugins, using [pytest](https://docs.pytest.org/) and [HTTPX](https://www.python-httpx.org/).

### New plugin hooks

-   [register_magic_parameters(datasette)](https://docs.datasette.io/en/stable/plugin_hooks.html#plugin-hook-register-magic-parameters) can be used to define new types of magic canned query parameters.
-   [startup(datasette)](https://docs.datasette.io/en/stable/plugin_hooks.html#plugin-hook-startup) can run custom code when Datasette first starts up. [datasette-init](https://github.com/simonw/datasette-init) is a new plugin that uses this hook to create database tables and views on startup if they have not yet been created. ([#834](https://github.com/simonw/datasette/issues/834))
-   [canned_queries(datasette, database, actor)](https://docs.datasette.io/en/stable/plugin_hooks.html#plugin-hook-canned-queries) lets plugins provide additional canned queries beyond those defined in Datasette's metadata. See [datasette-saved-queries](https://github.com/simonw/datasette-saved-queries) for an example of this hook in action. ([#852](https://github.com/simonw/datasette/issues/852))
-   [forbidden(datasette, request, message)](https://docs.datasette.io/en/stable/plugin_hooks.html#plugin-hook-forbidden) is a hook for customizing how Datasette responds to 403 forbidden errors. ([#812](https://github.com/simonw/datasette/issues/812))

### Smaller changes

-   Cascading view permissons - so if a user has `view-table` they can view the table page even if they do not have `view-database` or `view-instance`. ([#832](https://github.com/simonw/datasette/issues/832))
-   CSRF protection no longer applies to `Authentication: Bearer token` requests or requests without cookies. ([#835](https://github.com/simonw/datasette/issues/835))
-   `datasette.add_message()` now works inside plugins. ([#864](https://github.com/simonw/datasette/issues/864))
-   Workaround for ""Too many open files"" error in test runs. ([#846](https://github.com/simonw/datasette/issues/846))
-   Respect existing `scope[""actor""]` if already set by ASGI middleware. ([#854](https://github.com/simonw/datasette/issues/854))
-   New process for shipping [Alpha and beta releases](https://docs.datasette.io/en/stable/contributing.html#contributing-alpha-beta). ([#807](https://github.com/simonw/datasette/issues/807))
-   `{{ csrftoken() }}` now works when plugins render a template using `datasette.render_template(..., request=request)`. ([#863](https://github.com/simonw/datasette/issues/863))
-   Datasette now creates a single [Request object](https://docs.datasette.io/en/stable/internals.html#internals-request) and uses it throughout the lifetime of the current HTTP request. ([#870](https://github.com/simonw/datasette/issues/870))",107914493,

-   Redesign of [register_output_renderer(datasette)](https://datasette.readthedocs.io/en/stable/plugins.html#plugin-register-output-renderer) to provide more context to the render callback and support an optional `""can_render""` callback that controls if a suggested link to the output format is provided.

-   The [Request object](https://datasette.readthedocs.io/en/stable/internals.html#internals-request), which is passed to several plugin hooks, is now documented. ([#706](https://github.com/simonw/datasette/issues/706))
-   New `metadata.json` option for setting a custom default page size for specific tables and views, see [Setting a custom page size](https://datasette.readthedocs.io/en/stable/metadata.html#metadata-page-size). ([#751](https://github.com/simonw/datasette/issues/751))
-   Canned queries can now be configured with a default URL fragment hash, useful when working with plugins such as [datasette-vega](https://github.com/simonw/datasette-vega), see [Setting a default fragment](https://datasette.readthedocs.io/en/stable/sql_queries.html#canned-queries-default-fragment).

-   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. ([#771](https://github.com/simonw/datasette/issues/771), [#773](https://github.com/simonw/datasette/issues/773))",107914493,

* Added documentation for `db.execute()`, see [await db.execute(sql, ...)](https://datasette.readthedocs.io/en/stable/internals.html#database-execute).
* Renamed `db.execute_against_connection_in_thread()` to `db.execute_fn()` and made it a documented method, see [await db.execute_fn(fn)](https://datasette.readthedocs.io/en/stable/internals.html#database-execute-fn).

For example, adding a template file called `templates/pages/about.html` will result in a new page being served at `/about` on your instance. See the [custom pages documentation](https://datasette.readthedocs.io/en/0.41/custom_templates.html#custom-pages) for full details, including how to return custom HTTP headers, redirects and status codes. (#648)

[Configuration directory mode](https://datasette.readthedocs.io/en/0.41/config.html#config-dir) (#731) allows you to define a custom Datasette instance as a directory. So instead of running the following:

    $ datasette one.db two.db \
      --metadata.json \
      --template-dir=templates/ \
      --plugins-dir=plugins \
      --static css:css

You can instead arrange your files in a single directory called `my-project` and run this:

    $ datasette my-project/

Also in this release:

-   New `NOT LIKE` table filter: `?colname__notlike=expression`. (#750)
-   Datasette now has a *pattern portfolio* at `/-/patterns` - e.g. <https://latest.datasette.io/-/patterns>. This is a page that shows every Datasette user interface component in one place, to aid core development and people building custom CSS themes. (#151)
-   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)
-   Installation documentation now covers how to [Install using pipx](https://datasette.readthedocs.io/en/0.41/installation.html#installation-pipx). (#756)
