News in 6.1.0
=============


User interface
--------------

* Message view now appears when an error or exception occurs.

* Added common keyboard shortcuts for closing tabs (:kbd:`Ctrl+W`), save as (:kbd:`Ctrl+Shift+S`) and for temporarily entering panning mode (by holding down :kbd:`Space`).

* Zooming using mouse wheel is now anchored to the mouse pointers position.
  This makes it more intuitive to navigate the flow view.

* Limit zooming in/out for flow views. The old indefinite zooming caused
  some graphical problems and wasn't really useful.

* Plots in the table viewer and figures in the figure viewer now have their default white background color instead of a background color from the OS.


Platform
--------

* Add command for resaving flow files in the current Sympathy version. Mainly useful to avoid large diffs when managing syx files with e.g. git. See :ref:`appendix_cli` for details.

* Fix a bug where some settings (most notably :guilabel:`Max number of
  processes`) were not read correctly from the settings file.

* Deprecate cli commands ``sympathy syg`` and ``sympathy sy``. Use ``sympathy gui`` and ``sympathy cli`` respectively instead.


Node Changes
------------

* New node: *Time synchronization* which synchronizes two tables in time by
  finding the time offset at which the features of two signals overlap the most.

* New node: *Frequency transform Image* lets you do two-dimensional fourier
  transformation directly on an Image without converting it back and forth to a
  Table.

* Improved configuration gui in :ref:`org.sysess.sympathy.data.table.renamesingletablecolumns`:

  * Add combobox editor for selecting an existing column to be renamed.
  * Add option to only match full column name.

* Improvements in :ref:`org.sysess.sympathy.visualize.bokehfigure`:

  * Better support for coloring scatter plots based on data.
  * Add heatmap plot type.

* Integer columns are now interpreted as seconds since 1970-01-01 (Unix timestamps) when converting to datetimes in :ref:`org.sysess.sympathy.data.table.convertcolumnstable`.

* Accept list of lists as json data in :ref:`org.sysess.sympathy.data.json.jsontotablenew`.

* Images from url data sources can now be loaded with :ref:`syip.loadimage`

* Add an optional parameter to include time column in the output from *Spectral
  (short time fourier) transform* node. When performing inverse stft this will
  instead remove the time column.

* NaN color can now be specified for heatmaps in
  :ref:`org.sysess.sympathy.visualize.figure`. This color will be used for
  NaN-valued cells.


API Changes
-----------

* Improvements to :ref:`interactive mode<interactive_mode>`:

  * Fix license handling. Running any node in interactive mode should now work as long as you have a valid license.
  * Added API reference documentation.
  * New functions: :func:`sympathy.app.interactive.start_session`, :func:`sympathy.app.interactive.end_session`, :func:`sympathy.app.interactive.session`.
  * Fixed a bug where :meth:`sympathy.app.interactive.SyiNode.configure` didn't actually store the configured parameters.
