I'm pleased to announce that Spyder **5.0** has been released and is available for
Windows, GNU/Linux and MacOS X: https://github.com/spyder-ide/spyder/releases

This release represents more than one year of development since version 4.0 was
released, and it introduces major enhancements and new features. The most important ones
are:

* Improved dark theme based on QDarkstyle 3.0.
* New light theme based on QDarkstyle 3.0.
* New look and feel for toolbars.
* New icon set based on Material Design.
* New API to extend core plugins, with the exception of the Editor, IPython
  console and Projects.

  status bar.
* New architecture to access and write configuration options.

  identifiers.

For a complete list of changes, please see our

Spyder 4.0 has been a huge success and we hope 5.0 will be as successful. For that we
fixed 54 bugs, merged 142 pull requests from about 16 authors and added more than
830 commits between these two releases.

Hi all,

On the behalf of the Spyder Project Contributors (https://github.com/spyder-ide/spyder/graphs/contributors),
I'm pleased to announce that Spyder 3.0 has been released and is available for
Windows, GNU/Linux and MacOS X: https://github.com/spyder-ide/spyder/releases

Spyder is a free, open-source (MIT license) interactive development environment
for the Python language with advanced editing, interactive testing, debugging
and introspection features. It was designed to provide MATLAB-like features
(integrated help, interactive console, variable explorer with GUI-based editors
for NumPy arrays and Pandas dataframes), it is strongly oriented towards
scientific computing and software development.

# Beta release

**Subject**: [ANN] Spyder 4.0 third release candidate


Hi all,

On the behalf of the [Spyder Project Contributors](https://github.com/spyder-ide/spyder/graphs/contributors),
I'm pleased to announce the third release candidate 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
one week after Spyder 4.0 rc2 and it includes more than 130 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](https://kite.com/) completion
      engine.
    * Code completion and linting are provided by the Python Language Server.

- IPython Console
    * Run files in an empty namespace.
    * Open dedicated consoles for Pylab, Sympy and Cython.
    * Run cells through a new function called `runcell`.
    * Run cells by name.

- Debugger
    * Code completion.
    * Execute multi-line statements.
    * Syntax highlighting.
    * Permanent history.
    * `runfile` and `runcell` can be called when the debugger is active.
    * Debug cells with `Alt+Shift+Return`.

- Variable Explorer
    * New viewer to inspect any Python object in a tree-like representation.
    * 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.
    * Restore the ability to refresh it while code is being executed.

- 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.
