 # Release Notes
 
-## 0.4.0 (unreleased)
+## 0.4.0 (13.07.2021)
+
+Release `0.4.0` brings many new major features to `weldx`
+
+### Highlights
+
+- [Quality Standards](https://weldx.readthedocs.io/en/latest/tutorials/quality_standards.html):
+  Users can now create and integrate their own quality standards by defining new ASDF schema definitions and loading
+  them into weldx. It is possible to add new definitions or modify existing schemas to create your own flavour of the
+  weldx standard.
+- [WeldxFile](https://weldx.readthedocs.io/en/latest/tutorials/weldxfile.html):
+  Create/Load/Modify asdf files directly using ``WeldxFile`` with many helpful utility functions included.
+- [TimeSeries support](https://weldx.readthedocs.io/en/latest/tutorials/welding_example_02_weaving.html#add-a-sine-wave-to-the-TCP-movement)
+  for ``LocalCoordinateSystem``:
+  It is now possible to define a time-dependent ``LocalCoordinateSystem`` with a simple function by passing
+  a ``TimeSeries``
+  object with a ``MathematicalExpression`` as ``coordinates``. For an example, click the link above.
+- [MeasurementChain](https://weldx.readthedocs.io/en/latest/tutorials/measurement_chain.html) \
+  The ``MeasurementChain`` has been reworked to be easier and more flexible to use.

 ### Data archiving
 
-The ultimate goal of this project is to store all information about the experiment in a single file.
-We choose the popular [ASDF](https://en.wikipedia.org/wiki/Advanced_Scientific_Data_Format) format for this task.
-This enables us to store arbitrary binary data, while maintaining a human readable text based header. All information is stored
-in a tree like structure, which makes it convenient to structure the data in arbitrary complex ways.

 The ASDF format and the provided extensions for WelDX types like
 
 - workpiece information (used alloys, geometries)
-- welding process parameters (GMAW parameters
+- welding process parameters (GMAW parameters)
 - measurement data
 - coordinate systems (robot movement, sensors)
 
 enables us to store the whole experimental pipeline performed in a modern laboratory.
 
 ## Design goals
 
-We seek to provide a user-friendly, well documented programming interface. All functions and classes in WelDX have attached
-documentation about the involved parameters (types and explanation), see [API docs](https://weldx.readthedocs.io/en/stable/api.html).
-Further we provide rich [Jupyter notebook tutorials](https://weldx.readthedocs.io/en/stable/tutorials.html) about the handling of the basic workflows.

-All involved physical quantities used in weldX (lengths, angles, voltages, currents, etc.) should be attached
-with a unit to ensure automatic conversion and correct mathematical handling. Units are being used in all standard features
-of WelDX and are also archived in the ASDF files. This is implemented by the popular Python library
-[Pint](https://pint.readthedocs.io/en/stable/), which flawlessly handles the creation and conversion of units and dimensions.

 ## Installation
 
-The WelDX package can be installed using conda or mamba package manager from the :code:`conda-forge` channel.
-These managers originate from the freely available [Anaconda Python stack](https://docs.conda.io/en/latest/miniconda.html).
-If you do not have Anaconda or Miniconda installed yet, we ask you to install `Miniconda-3`.
-Documentation for the installation procedure can be found [here](https://docs.conda.io/projects/conda/en/latest/user-guide/install/index.html#regular-installation).
-After this step you have access to the conda command and can proceed to installing the WelDX package.
