Spyder 6.0.0 (2024-09-03)

New features

• New installers for Windows, Linux and macOS based on Conda and Conda-forge. They come up with a more robust update process and are based on Python 3.11.
• Add a Debugger pane to explore the stack frame of the current debugging session.
• Add a button to the Debugger pane to pause the current code execution and enter the debugger afterwards.
• Add submenu to the Consoles menu to start a new console for a specific Conda or Pyenv environment.
• Add ability to refresh the open Variable Explorer viewers to reflect the current variable value.
• Add initial support to automatically connect to remote servers through SSH and run code in them. This functionality can be found in the menu Consoles > New console in remote server.
• Show plots generated in the Variable Explorer or its viewers in the Plots pane.
• Show Matplotlib backend and Python environment information in the status bar.
• Make kernel restarts be much faster for the current interpreter.
• Add experimental support for Qt 6 and increase minimal required version to Qt 5.15.
• Turn runfile, debugfile, runcell and related commands into IPython magics.

Important fixes

• Environment variables declared in ~/.bashrc or ~/.zhrc are detected and passed to the IPython console.
• Support all real number dtypes in the dataframe viewer.
• Respect Matplotlib user settings configured outside Spyder.
• Increase DPI of Matplotlib plots so they look better in high resolution screens.
• Allow to copy the absolute and relative paths of the current file to the tabs' context menu of the Editor.
• Restore ability to load Hdf5 and Dicom files through the Variable Explorer (this was working in Spyder 4 and before).
• Add ability to disable external plugins in Preferences > Plugins.
• Use a simpler filesystem watcher in Projects to improve performance.

UX/UI improvements

• Make Spyder accept Chinese, Korean or Japanese input on Linux by adding fcitx-qt5 as a new dependency (in conda environments only).
• The file switcher can browse and open files present in the current project ( in conda environments or if the fzf package is installed).
• Improve how options are displayed and handled in several Variable Explorer viewers.
• The interface font used by the entire application can be configured in Preferences > Appearance.
• Files can be opened in the editor by pasting their path in the Working Directory toolbar.
• Add a new button to the Variable Explorer to indicate when variables are being filtered.
• Show intro message for panes that don't display content at startup.

New, updated and removed plugins

• Add a Switcher plugin for the files and symbols switcher.
• Add a Debugger plugin to centralize all functionality related to debugging.
• Add an External Terminal plugin to execute Python and Bash/Batch/PS1 files on a system terminal.
• Generalize the Run plugin to support generic inputs and executors. This allows plugins to declare what kind of inputs (i.e. file, cell or selection) they can execute and how they will display the result.
• Declare a proper API for the Projects plugin.
• The Editor now uses the API introduced in Spyder 5. That was the last built-in plugin that needed to be migrated to it.
• The Breakpoints plugin was removed and its functionality moved to the Debugger one.

New API features

• SpyderPluginV2.get_description must be a static method and SpyderPluginV2.get_icon a class or static method. This is necessary to display the list of available plugins in Preferences in a more user-friendly way (see PR PR 21101 for the details).
• SpyderPlugin and SpyderPluginWidget are no longer exposed in the public API. They will be removed in Spyder 6.1.
• All comboboxes must inherit from SpyderComboBox or related subclasses in spyder.api.widgets.comboboxes. Comboboxes that inherit directly from QComboBox won't follow Spyder's graphical style.
• All menus must inherit from SpyderMenu in spyder.api.widgets.menus.
• All dialog button boxes must inherit from SpyderDialogButtonBox in spyder.api.widgets.dialogs.
• Helper classes were added to spyder.api.fonts to get and set the fonts used in Spyder in different widgets.
• Helper classes were added to spyder.api.shortcuts to get and set keyboard shortcuts.
• AsyncDispatcher was added to spyder.api.asyncdispatcher to run asyncio code in Spyder. Only Qt signals can be attached to asyncio future.add_done_callback calls to avoid segfaults.
• ShellConnectStatusBarWidget was added to spyder.api.shellconnect.status to create status bar widgets connected to the current console.

• Notify Spyder when Matplotlib backend changes.
• Use control channel for comms instead of a special one.
• Update variable explorer from the kernel.
• Simplify kernel configuration from Spyder.
• Add a comm_handler decorator.
• Transform runfile, debugfile and runcell commands to IPython magics.
• Add comm handlers to interrupt executions and enter the debugger after that.
• Publish Pdb stack frames to Spyder.
• Drop support for Python 2 and support Python 3.8+
