QCoDeS 0.62.0 (2026-10-26)
==========================

Improved:
---------

- ``qcodes.utils.is_qcodes_installed_editably`` no longer shells out to ``pip`` to detect an
  editable install. The editable status is now read directly from the installed package
  metadata (the :pep:`610` ``direct_url.json`` file), which both ``pip`` and ``uv`` write.
  This means the check also works in environments where ``pip`` is not installed, such as
  environments managed by ``uv``, and it no longer requires spawning a subprocess. (:pr:`8580`)
- Add :func:`qcodes.dataset.get_open_connections` and
  :func:`qcodes.dataset.close_all_connections` to inspect and close tracked database
  connections. Connections owned by the exiting thread are also closed automatically
  at interpreter shutdown. Test cleanup closes connections opened during each test
  without closing connections owned by broader-scoped fixtures or other threads. (:pr:`8626`)
- The type annotations of ``Station.load_all_instruments`` now accept calling it without
  arguments or with only one of ``only_names`` and ``only_types``. Previously these valid
  calls matched none of the overloads and were rejected by static type checkers. (:pr:`8644`)


Improved Drivers:
-----------------

- Allow the Yokogawa GS200 driver to use the documented generated output ranges,
  including 12 V on the 10 V source range, while retaining the 32 V and 200 mA
  maximum output limits for direct output and ramps. (:pr:`8577`)
- ``AlazarTechATS.acquire`` is now annotated to accept any ``AcquisitionInterface`` as
  ``acquisition_controller``, not only an ``AcquisitionController``, matching what it supports
  at runtime. ``AcquisitionController`` now passes its type parameter on to
  ``AcquisitionInterface``, so the return type of ``acquire`` is inferred from the
  ``post_acquire`` return type of the controller. Subclasses of ``AcquisitionController[T]``
  whose ``post_acquire`` does not return ``T`` will now be reported by static type checkers. (:pr:`8644`)
- Added missing type annotations to the optional arguments of the Keysight B1500
  ``MessageBuilder`` methods ``ercmaio``, ``lst_query``, ``pch_query``, ``sprm``, ``tc``
  and ``wat``. (:pr:`8644`)
- The Galil DMC-41x3 driver now retries empty or malformed controller replies when polling motion status and axis positions, and waiting for motion to complete is bounded by a timeout (300 s by default) that raises ``TimeoutError``. Each motion-status query is limited by the remaining motion timeout, with millisecond resolution, and restores the original I/O timeout afterward. Connecting now falls back through the ``--direct -s ALL`` and ``-s ALL`` options before using the bare address. Pressing Ctrl-C while waiting for motion now calls ``abort()`` and then turns the axes off with ``MO``. (:pr:`8647`)


Under the hood:
---------------

- QCoDeS is now tested against Python 3.15 on Linux. The ``zhinst-qcodes`` test dependency is not installed
  on Python 3.15 since ``zhinst-core`` does not yet provide wheels for it. (:pr:`8581`)
- The minimum supported version of ``typing_extensions`` is now 4.12.0. Older versions do not
  apply the default of a ``TypeVar``, so subscripting a parameter with only its value type at
  runtime, e.g. ``Parameter[int]``, failed with ``TypeError: Too few arguments`` on Python 3.12. (:pr:`8644`)
