Hi all,

On the behalf of the Spyder Project Contributors, I’m pleased to announce the sixth beta of our next major version: Spyder 4.0.

We’ve been working on this version for more than three years now and as far as we know it’s working very well. There are still several bugs to squash but we encourage all people who like the bleeding edge to give it a try. This beta version is released 4 weeks after Spyder 4.0 beta5 and it includes more than 275 commits.

Spyder 4.0 comes with several interesting and exciting new features. The most important ones are:

  • Main Window

    • Dark theme for the entire application.
    • A new Plots pane to browse all inline figures generated by the IPython console.
    • Rename the following panes:
      • Static code analysis to Code Analysis
      • File explorer to Files
      • Find in files to Find
      • History log to History
      • Project explorer to Project
    • Create a separate window when undocking all panes.
    • Show current conda environment (if any) in the status bar.

  • Editor

    • Code folding.
    • Indentation guides.
    • A class/method/function lookup panel. This can be shown in the menu Source > Show selector for classes and functions.
    • Autosave functionality to recover unsaved files after a crash.
    • Optional integration with the Kite completion engine.
    • Code completion and linting are provided by the Python Language Server.

  • IPython Console

    • Run files in an empty namespace.
    • Create dedicated consoles for Pylab, Sympy and Cython.
    • Run cells through a new function called runcell.
    • Run cells by name.

  • Debugger

    • runfile and runcell can be called when the debugger is active.
    • Debug cells by pressing Alt+Shift+Return.
    • Permanent history.
    • Syntax highlighting.

  • Variable Explorer

    • New viewer to inspect any Python object in a tree-like view.
    • Filter variables by name or type.
    • MultiIndex support in the Dataframe viewer.
    • Support for all Pandas indexes.
    • Support for sets.
    • Support for Numpy object arrays.

  • Files

    • Associate external applications to open specific file extensions.
    • Context menu action to open files externally.
    • Multi-select functionality with Ctrl/Shift + mouse click.
    • Copy/paste files and their absolute or relative paths.
    • Use special icons for different file types.

  • Outline

    • Show cells grouped in sections.
    • Add default name to all cells.

For a more complete list of changes, please see our changelog

You can easily install this beta if you use Anaconda by running:

conda update qt pyqt
conda install -c spyder-ide spyder=4.0.0b6

Or you can use pip with this command:

pip install --pre -U spyder

Enjoy!

I just upgraded MY Windows 10 installation to 4.0.0b6 from b5.  Unfortunately, there are errors on startup:

Hi. Since installing the new version of spyder 4.0 from anaconda, I am having a hard time using this new version. Repeatedly and without prior notice, I can not run the code (the red light disappears) and many times it freezes or the whole spyder dies.
I am desperate because I do not see that anyone is happening .. Help please
