  Changelog
 ===========
 
+.. _v3_39:
+
+3.39 (2025-11-24)
+-----------------
+
+- Fixed a bug with ``sqlite-utils install`` when the tool had been installed using ``uv``. (:issue:`687`)
+- The ```--functions``` argument now optionally accepts a path to a Python file as an alternative to a string full of code, and can be specified multiple times - see :ref:`cli_query_functions`.  (:issue:`659`)
+- ``sqlite-utils`` now requires on Python 3.10 or higher.
+
+`sqlite-utils 4.0a1 <https://sqlite-utils.datasette.io/en/latest/changelog.html#a1-2025-11-23>`__ is now available as an alpha with some `minor breaking changes <https://simonwillison.net/2025/Nov/24/sqlite-utils-40a1/>`__.

 By default registering a function with the same name and number of arguments will have no effect - the ``Database`` instance keeps track of functions that have already been registered and skips registering them if ``@db.register_function`` is called a second time.
 
 If you want to deliberately replace the registered function with a new implementation, use the ``replace=True`` argument:
