Changelog

All notable changes to this project are documented here.

The format is based on Keep a Changelog

[Unreleased]

Added

Changed

Deprecated

Removed

  • The Filter button has been removed from Spine Database Editor's toolbar. The functionality was broken anyhow and has been superseded by filtering from the Scenario tree.

Fixed

Security

[0.9.1]

Changed

  • Add/Update SpineOpt wizard in File->Settings->Tools now installs SpineOpt v0.9.0 from Julia's General Registry. Previously SpineOpt was installed from a custom SpineJuliaRegistry registry.

Removed

  • Removed support for MSSQL dialect. It did not work anyway.

[0.9.0]

Dropped support for Python 3.8. This version of Spine Toolbox requires Python version from 3.9 to 3.12.

Changed

  • Add/Update SpineOpt wizard in File->Settings->Tools now requires SpineOpt v0.8.3 or higher.

[0.8.5]

Changed

  • Execution button shortcuts have been changed because F5 is traditionally reserved for refreshing. The shortcuts are now:

    • Shift+F9 to execute project
    • F9 to execute selection
    • F10 to stop execution

Fixed

  • Fixed a bug where scenario filters could cause Tracebacks in tools that were using spinedb_api.

[0.8.4]

Changed

  • gamsapi replaced the ancient gdxcc package. You may need to have a relatively recent GAMS installed to utilize .gdx import/export functionalities.

[0.8.3]

Added

  • Entity group column in Add entities dialog. If filled, the created entity will be added to the specified group. If the group doesn't yet exist, it will be created.
  • Native kernel (i.e. python3 for Python) can now be used in the Detached Console or in Tool execution.
  • It is now possible to specify valid value types for parameters in the Parameter definition table in Database editor.
  • [Bundled App] Embedded Python now includes pip.
  • Graph view in database editor now also supports filtering by alternative and scenario tree selections.
  • Option to disable auto-build in entity graph.
  • Mapping Name source type in importer.
  • Importer has now an option to import entity alternatives.

Changed

  • Database editor's hamburger menu has been converted into a menubar beneath the tab bar. The URL toolbar has also been replaced with a toolbar that houses different buttons.
  • One dimensional entities can now also be added through Parameter value and Entity alternative tables.
  • Special data types like dates, times and booleans are now properly pasted from Excel.

Fixed

  • [Bundled App] Fixed execution in Jupyter Console and opening Detached Consoles by adding jupyter-client and qtconsole packages to the bundle.
  • [Bundled App] Fixed creating new kernel specs in Settings->Tools by adding ipykernel package to the embedded Python.
  • [Bundled App] Fixed 'Install Julia' button in Settings->Tools by adding the jill package to the embedded Python.

[0.8.2]

Added

  • A button next to each entity class in Entity Tree that opens the Add entities dialog.
  • Alternative -column in Add entities dialog. If filled, the created entity will be set active in that alternative.

Changed

  • Python 3.12 and later is now supported.
  • When exporting GAMS .gdx files with Exporter, special values 10-10 and EPS now get converted to GAMS Eps (epsilon).

[0.8.1]

Added

  • Importer: it is now possible to reorder source tables by dragging and dropping.
  • Importer: it is now possible to reorder mappings by dragging and dropping.
  • Importer: it is now possible to copy mappings between source tables by dragging selected mappings from Mappings list onto destination source table item.

Removed

  • Scenario active flag mappings have been removed from Importer and Exporter. The flag is not used anywhere and has not been accessible in Database editor for a long time.

[0.8.0]

Added

  • New context menu action (Select superclass) for entity class items in the entity tree.
  • Added Tool Specification type (Python, Gams, etc.) icons on Design View.
  • There is now a new filter type, Alternative filter available in Link properties. Unlike scenario filters, the execution is not parallelized. Instead, a successor item sees parameter values of all selected alternatives. Because of this behavior, alternative filters cannot be used at the same time with scenario filters. Link properties tab has a combo box that lets one choose which filter type to use.

Changed

Spine data structure

Many parts of the Spine data structure have been redesigned.

  • Entities have replaced objects and relationships. Zero-dimensional entities correspond to objects while multidimensional entities replace the former relationships. Unlike relationships, the elements of multidimensional entities can now be other multidimensional entities.
  • Simple inheritance is now supported by superclasses.
  • Tools, features and methods have been removed. The functionality that was previously implemented using the is_active parameter has been replaced by entity alternatives. Entity classes have a default setting for the entity alternative called active by default. Database migration should automatically replace tools, features and methods by entity alternatives and set active by default to whatever default value is_active or similar parameter had. The is_active parameter is not removed from entity classes but its values are.
  • Note that new zero-dimensional entity classes have active by default set to false initially. This means that the entities of those classes are hidden when using scenario filters unless specifically shown using entity alternatives.

Miscellaneous changes

  • "Rubber band" selection of items in Design and Graph views is now done with left mouse button (no need to press Ctrl anymore). The views can be dragged around by holding the right mouse button.
  • Spine Database Editor now remembers the configuration of the docs in each view for a specific URL. The docks can be reset from the hamburger menu View->Docks...->Reset docks.
  • You can now select a different Julia executable & project or Julia kernel for each Tool spec. This overrides the global setting from Toolbox Settings.
  • Headless mode now supports remote execution (see 'python -m spinetoolbox --help')
  • Commit Viewer's UI has undergone some redesigning and can now handle large databases.

Removed

  • Project dock widget
  • Dependency on Dagster

[0.7.4]

Changed

  • Microsoft build tools are not needed anymore when installing Toolbox requirements on Python 3.10 and up.

[0.7.3]

Added

  • On Toolbox startup, a link appears in Event log that opens Upgrade notification window offering information about the upcoming 0.8 update.

[0.7.2] - 2023-12-04

Added

  • Data Connection items now support schemas in database references
  • Importer Specification Editor now supports database schemas

[0.7.1] - 2023-10-06

Added

  • Allow choosing of highlight color for items found in entity graph

Fixed

  • Fixed issues when remote databases were used as references in Data Connections
  • Fixed a bug where the order of scenario alternatives would be messed up when copy-pasting the alternatives in the Scenario Tree
  • Fixed a bug with time series plots
  • Fixed issues with Pivot table

[0.7.0] - 2023-08-25

Added

  • Support for version 11 Spine Toolbox projects.
  • Executable Tool Specifications can be used to run any (shell) command. This enhancement duplicates the functionality of Gimlet project items and makes them obsolete.
  • There is now an option to select if new scenarios or tools are automatically used for filtering in Link properties.
  • The new "Filer validation" button in Link properties allows forcing at least one scenario or tool filter to be checked.
  • Python 3.11 support.
  • PySide6 support. The app has been ported from PySide2 to PySide6.
  • In addition to dragging and dropping, it is now possible to copy alternatives from Alternative tree and paste them to the scenario tree in Database editor.
  • Scenarios can now be copied and pasted between databases in Database editor.
  • Scenarios can now be duplicated in Database editor.
  • Tool project item's Python and Julia consoles can now be killed from the right-click context menu. A killed console can be restored by restarting it.
  • A new option "Kill consoles at the end of execution" has been added to Tool properties, that kills Python and Julia console processes after execution saving some memory and computing resources.
  • A new option "Log process output to a file" has been added to Tool properties, that logs all the 'console' output of the Tool to a file in the logs subfolder.
  • You can now open a 'Detached' Jupyter Console on any kernel you have installed in your system from the Consoles main window menu.
  • "Make Julia Kernel" and "Make Python Kernel" buttons in Settings->Tools page. Clicking them creates a new Julia or Python kernel based on selected Julia/Python executable on the same page if the kernel does not exist. If the kernel already exists, it is selected automatically.
  • project.json now has an experimental option ["project"]["settings"]["enable_execute_all"] which disables the Execute Project button when set to false. The option is currently not settable in the UI.
  • New context menu action (Find...) to find items by name in DB editor's entity graph.

Changed

  • The console settings of Python tools as well as the command and shell settings of executable tools are now treated as project-specific data and stored in <project root>/.spinetoolbox/local/specification_local_data.json. This should make it easier to share projects over e.g. Git.
  • Scenario and tool filters are now ON by default. If new scenario or tool is added to a database it will be automatically selected in outgoing connections. NOTE: In existing projects, if a connection did not have any scenarios/tools selected, they will all be selected when opening a project for the first time after this change. If this is not desired, the scenarios/tools need to be deselected manually before saving the project on disk.
  • Project name is now the project directory name and cannot be changed unless by moving the project to another directory manually or by using the File -> Save project as... menu item.
  • Scenario filters now filter unrelated scenarios and alternatives as well.
  • Alternative/Scenario tree in Database editor has been split into separate Alternative tree and Scenario tree docks. This will hopefully make dragging and dropping alternatives to scenarios easier.
  • Logic of executing selected project items. URL's passed by unselected Data Transformers are not included automatically into selective execution anymore. When selecting project items for execution, make sure to select also preceding Data Transformers if needed.
  • Names for duplicate items/scenarios/etc now use the format prefix (xx) instead of prefix xx. Duplicating a previously duplicated item now has the number xx incremented instead of having a new number appended.
  • "Open kernel spec editor" buttons in Settings->Tools page have been changed "Make Julia kernel" and "Make Python Kernel" buttons

Deprecated

Removed

  • Python 3.7 support
  • GdxExporter project item. Please use Exporter instead.
  • Gimlet project item. Please use Tool instead.
  • The possibility to import parameter values when importing object groups using Importer. Existing mappings will not import group parameters anymore. Please add explicit parameter import mappings if needed.
  • The possibility to export parameter values when exporting object groups using Exporter. Existing mappings will not export group parameters anymore. Please add explicit parameter export mappings if needed.
  • Execute in work setting in Tool Specification Editor. Please use Execute in work setting in Tool Properties instead.
  • Kernel Spec Editor widget and the "Open Kernel Spec Editor" button in Tool Specification Editor

Fixed

  • Deleting the last item of a mapping in the importer specification editor no longer disables the 'add' button.
  • Group Id's for Jupyter Consoles
  • Kill consoles at end of execution for Jupyter Consoles
  • Crash when typing exit, exit(), quit, or quit() into Jupyter Console

Security

Fixed

  • [win-x64] Fixed /tools/python.exe by adding sitecustomize.py and a missing python37.dll

[0.5.0-final.0] - 2020-12-14

Added

  • Exporting graphs as PDF files from the Graph menu in the Data Store form.
  • Pruning entire classes from the graph view. The option is available both from the Graph menu and from Entity Graph context menus. Also, pruned items can be restored gradually.
  • A new Input type Indexed parameter expansion is now available in Data Store view's Pivot table. In this Input type the indexes, e.g. time stamps of time series get expanded as a new dimension in the table.
  • Import editor now has a new Source type: Table name. It can be used e.g. to pick an Excel sheet's or GAMS domain's name as the object class name.
  • Import editor now supports multidimensional maps. The number of dimensions can be set using the Map dimensions spin box in mappings options.
  • Executing a project from the command line without opening the Toolbox GUI (i.e. headless execution). The headless execution is enabled by the new command line option --execute-only.
  • Toolbox now supports scenarios and alternatives. They can be accessed via Data store view's new Alternative tree.

  • [win-x64] Includes Tools/python.exe for running Python Tools for systems that do not have a Python installation. Also, pyvenv.cfg and path.pth files for configuring the included python.exe.

Fixed

  • Signal disconnection issue in Graph View
  • Bugs in removing objects and object classes in Spine db editor's Graph View

Changed

  • Data Store Form is now called 'Spine database editor'
  • Spine db editor Graph View behavior. Now selecting objects in the object tree not only shows those objects but also all the cascading relationships. One can still go back to the previous behavior in Settings.
  • Moving object items in the graph view also causes relationship icons to follow. This behavior can be disabled in the Settings.
  • Required PySide2 version is now 5.14. The version is checked at startup.
  • Indexed parameter handling has been overhauled in Exporter allowing parameters to share indexing domains. Note: Due to numerous changes in the backend, Exporters in old project files will not load properly and need to be re-configured.
  • The way Exporter handles missing parameter values and None values has changed. The item now ignores missing values instead of replacing them by the default value. Further, there is a new option to replace None values by the default value and another option to replace Nones by not-a-numbers or skip exporting them.
  • The numerical indicator on the upper left corner of project items no longer indicates the execution order for each individual item because the exact order is not know before the Execute button is actually clicked. The number still indicates the execution order but may show the same numbers for items in different parallel branches.
  • Project.json file format has been upgraded to version 2. Version 1 project.json files are upgraded to version 2 automatically when a project is opened.
  • Default Python interpreter is now {sys.executable} i.e. the one that was used in launching the app. This affects the Python used by Python Tool specifications and the PyCall used by SpineOpt.jl configuration assistant.
  • [win-x64] Default Python interpreter is the Python in user's PATH if available. If Python is not defined in user's PATH, the default Python interpreter is the <app_install_dir>/Tools/python.exe.
  • User's now need to explicitly choose the kernel specs for the Python Console and the Julia Console. They are not chosen (nor created) automatically anymore. The kernel specs can be selected in the drop-down menus in application Settings->Tools.
  • Database revision handling has been improved. Id est, the app does not offer to upgrade databases that are more recent than the current version of Spine Toolbox can handle.
  • Links to User Guide and Getting Started documents open only the online versions. The docs have been published on readthedocs.org.
  • Clearing the line edits for Julia executable and Python Interpreter (in Settings->Tools) shows the full paths to their respective files as placeholder text.

Deprecated

  • CustomQtKernelManager class

Removed

  • python_repl_widget.py
  • julia_repl_widget.py
