QCoDeS 0.40.0 (2023-09-14)
==========================

Improved:
---------

- Very noisy log messages from `azure.monitor.opentelemetry.exporter` are now
  by default filtered and not shown in the console logger. This matches the
  behavior of the OpenCensus exporter. (:pr:`5278`)
- The InstrumentLoggerAdapter has been updated to store the `instrument_name` and `instrument_type`
  as fields on log records rather than the instrument it self. This enables opentelemetry to attache
  the fields to a transmitted LogRecord for better filtering. (:pr:`5297`)
- In the QCoDeS DataSetProtocol newly created dataset now always have a captured_run_id / captured_counter
  that matches the run_id / result_counter that they are assigned on creation. Previously these could be
  out of sync if datasets measured elsewhere had been inserted into the database. (:pr:`5329`)
- The `pyvisa.ResourceManager` of a VISA instrument is now exposed
  as `instr.resource_manager`. All VISA instruments will now use `weakref.finalize`
  to close the visa resource on shutdown of the instrument. This should reduce the
  chance that an instrument resource is not cleanup correctly on exit. (:pr:`5341`)


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

- Parameters controlling the pid-values, pumps and state of the temperature channels have been added to OxfordTriton.
  This allows temperature sweeps from base temperature to several Kelvin to be fully automatic. Code to create such sweeps can be found at https://github.com/qdev-dk/MeasFunc/blob/main/measfunc/temperature_sweep.py. (:pr:`5316`)


New:
----

- The QCoDeS Measurement Context manager, DataSaverBuilder and DoND functions have been instrumented as OpenTelemetry traces.
  This enables users to correlate log messages with the the measurement that they were performed within.
  See the `OpenTelemetry <https://opentelemetry.io/>`_ documentation for examples of how this can be used.

  The log exporting using OpenCensus within QCoDeS is expected to be deprecated and eventually removed in line
  with OpenCensus being discontinued. Users that are interested in gathering telemetry of their setups are encouraged
  to provide their own solution based on OpenTelemetry. (:pr:`5289`)
- New features: datasaver_builder and dond_into are intermediate measurement extensions designed to fill a gap between
  the low-level Measurement object and the high-level doNd functions. They allow convenient specification of parameter
  dependencies for registration and doNd-like syntax while also allowing direct access to the underlying datasaver objects. (:pr:`5294`)
