============================
.. note:: Read more on these features on `the FlexMeasures blog <https://flexmeasures.io/019-asset-nesting/>`__.
.. warning:: This version replaces FLASK_ENV with FLEXMEASURES_ENV (FLASK_ENV will still be used as a fallback).
New features
-------------
* List child assets on the asset page [see `PR 967 <https://github.com/FlexMeasures/flexmeasures/pull/967>`_]
* Expand the UI's breadcrumb functionality with the ability to navigate directly to sibling assets and sensors using their child-parent relationship [see `PR 977 <https://github.com/FlexMeasures/flexmeasures/pull/977>`_]
* Enable the use of QuantityOrSensor fields for the ``flexmeasures add schedule for-storage`` CLI command [see `PR 966 <https://github.com/FlexMeasures/flexmeasures/pull/966>`_]
* CLI support for showing/savings time series data for a given type of source only, with the new ``--source-type`` option of ``flexmeasures show beliefs``, which let's you filter out schedules, forecasts, or data POSTed by users (through the API), which each have a different source type [see `PR 976 <https://github.com/FlexMeasures/flexmeasures/pull/976>`_]
* New CLI command ``flexmeasures delete beliefs`` to delete all beliefs on a given sensor (or multiple sensors) or on sensors of a given asset (or multiple assets) [see `PR 975 <https://github.com/FlexMeasures/flexmeasures/pull/975>`_]
* Support for defining the storage efficiency as a sensor or quantity for the ``StorageScheduler`` [see `PR 965 <https://github.com/FlexMeasures/flexmeasures/pull/965>`_]
* Support a less verbose way of setting the same :abbr:`SoC (state of charge)` constraint for a given time window [see `PR 899 <https://github.com/FlexMeasures/flexmeasures/pull/899>`_]
Infrastructure / Support
----------------------
* Deprecate use of flask's ``FLASK_ENV`` variable and replace it with ``FLEXMEASURES_ENV`` [see `PR 907 <https://github.com/FlexMeasures/flexmeasures/pull/907>`_]
* Streamline CLI option naming by favoring ``--<entity>`` over ``--<entity>-id`` [see `PR 946 <https://github.com/FlexMeasures/flexmeasures/pull/946>`_]
* Documentation: improve index page, installation overview, feature overview incl. flex-model overview and UI screenshots [see `PR 953 <https://github.com/FlexMeasures/flexmeasures/pull/953>`_]
* Faster database queries of time series data by upgrading SQLAlchemy and timely-beliefs [see `PR 938 <https://github.com/FlexMeasures/flexmeasures/pull/938>`_]
