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. ([#1970](https://github.com/simonw/datasette/issues/1970))",107914493,"{""url"": ""https://api.github.com/repos/simonw/datasette/releases/115813784/reactions"", ""total_count"": 3, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 3, ""eyes"": 0}"

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). ([#1855](https://github.com/simonw/datasette/issues/1855))
- New datasette.create_token() API method <datasette_create_token>` for programmatically creating signed API tokens. ([#1951](https://github.com/simonw/datasette/issues/1951))
- `/db/-/create` API now requires actor to have `insert-row` permission in order to use the `""row""` or `""rows""` properties. ([#1937](https://github.com/simonw/datasette/issues/1937))",107914493,

- Fixed a bug where the `_memory` database could be written to even though writes were not persisted. ([#1917](https://github.com/simonw/datasette/issues/1917))
- 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))
- Fixed a bug where hitting the write endpoints with a `GET` request returned a 500 error. It now returns a 405 (method not allowed) error instead. ([#1916](https://github.com/simonw/datasette/issues/1916))
- The list of endpoints in the API explorer now lists mutable databases first. ([#1918](https://github.com/simonw/datasette/issues/1918))
- The `""ignore"": true` and `""replace"": true` options for the insert API are [now documented](https://docs.datasette.io/en/latest/json_api.html#tableinsertview). ([#1924](https://github.com/simonw/datasette/issues/1924))",107914493,

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.

- 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

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))

-   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))

### 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)).
- New [debug-menu](https://docs.datasette.io/en/stable/authentication.html#permissions-debug-menu) permission. ([#1068](https://github.com/simonw/datasette/issues/1068))
- Removed `--debug` option, which didn't do anything. ([#814](https://github.com/simonw/datasette/issues/814))
- `Link:` HTTP header pagination. ([#1014](https://github.com/simonw/datasette/issues/1014))

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))

### 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. ([#581](https://github.com/simonw/datasette/issues/581), [#770](https://github.com/simonw/datasette/issues/770))
-   Visually distinguish float and integer columns - useful for figuring out why order-by-column might be returning unexpected results. ([#729](https://github.com/simonw/datasette/issues/729))
-   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). ([#706](https://github.com/simonw/datasette/issues/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](https://github.com/simonw/datasette/issues/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. ([#771](https://github.com/simonw/datasette/issues/771), [#773](https://github.com/simonw/datasette/issues/773))",107914493,
