0.61a0

• Removed hashed URL mode from Datasette. The new datasette-hashed-urls plugin can be used to achieve the same result, see datasette-hashed-urls for details. (#1661)
• Databases can now have a custom path within the Datasette instance that is indpendent of the database name, using the db.route property. (#1668)
• URLs within Datasette now use a different encoding scheme for tables or databases that include "special" characters outside of the range of a-zA-Z0-9_-. This scheme is explained here: Tilde encoding. (#1657)
• Table and row HTML pages now include a <link rel="alternate" type="application/json+datasette" href="..."> element and return a Link: URL; rel="alternate"; type="application/json+datasette" HTTP header pointing to the JSON version of those pages. (#1533)
• Access-Control-Expose-Headers: Link is now added to the CORS headers, allowing remote JavaScript to access that header.
• Canned queries are now shown at the top of the database page, directly below the SQL editor. Previously they were shown at the bottom, below the list of tables. (#1612)
• Datasette now has a default favicon. (#1603)
• sqlite_stat tables are now hidden by default. (#1587)
• SpatiaLite tables data_licenses, KNN and KNN2 are now hidden by default. (#1601)
• Python 3.6 is no longer supported. (#1577)
• Tests now run against Python 3.11-dev. (#1621)
• Fixed bug where custom pages did not work on Windows. Thanks, Robert Christie. (#1545)
• SQL query tracing mechanism now works for queries executed in asyncio sub-tasks, such as those created by asyncio.gather(). (#1576)
• datasette.tracer mechanism is now documented.
• Common Datasette symbols can now be imported directly from the top-level datasette package, see Import shortcuts. Those symbols are Response, Forbidden, NotFound, hookimpl, actor_matches_allow. (#957)
• /-/versions page now returns additional details for libraries used by SpatiaLite. (#1607)
• Documentation now links to the Datasette Tutorials.
• Datasette will now also look for SpatiaLite in /opt/homebrew - thanks, Dan Peterson. (#1649)
• Datasette is now covered by a Code of Conduct. (#1654)

0.60.2

• Fixed a bug where Datasette would open the same file twice with two different database names if you ran datasette file.db file.db. (#1632)

0.60.1

• Fixed a bug where installation on Python 3.6 stopped working due to a change to an underlying dependency. This release can now be installed on Python 3.6, but is the last release of Datasette that will support anything less than Python 3.7. (#1609)

Plugins and internals

• New plugin hook: filters_from_request(request, database, table, datasette), which runs on the table page and can be used to support new custom query string parameters that modify the SQL query. (#473)
• Added two additional methods for writing to the database: await db.execute_write_script(sql, block=True) and await db.execute_write_many(sql, params_seq, block=True). (#1570)
• The db.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)
• Database write connections now execute the prepare_connection(conn, database, datasette) plugin hook. (#1564)
• The Datasette() constructor no longer requires the files= argument, and is now documented at Datasette class. (#1563)
• The tracing feature now traces write queries, not just read queries. (#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)

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)
• Facets of type date or array can now be configured in metadata.json, see Facets in metadata.json. Thanks, David Larlet. (#1552)
• New ?_nosuggest=1 parameter for table views, which disables facet suggestion. (#1557)
• Fixed bug where ?_facet_array=tags&_facet=tags would only display one of the two selected facets. (#625)

Other small fixes

• Made several performance improvements to the database schema introspection code that runs when Datasette first starts up. (#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)
• Upgraded Pluggy dependency to 1.0. (#1575)
• Now using Plausible analytics for the Datasette documentation.
• explain query plan is now allowed with varying amounts of whitespace in the query. (#1588)
• New CLI reference page showing the output of --help for each of the datasette sub-commands. This lead to several small improvements to the help copy. (#1594)
• Fixed bug where writable canned queries could not be used with custom templates. (#1547)
• Improved fix for a bug where columns with a underscore prefix could result in unnecessary hidden form fields. (#1527)

0.59.3
