Hi all,

On the behalf of the Spyder Project Contributors, I’m pleased to announce that Spyder 4.1.0 has been released and is available for Windows, GNU/Linux and MacOS X: https://github.com/spyder-ide/spyder/releases

This release comes two months and a half after version 4.0.1 and it contains the following new features and important fixes:

New features:
- Several improvements to the interface and user experience of the Plots pane.
- Allow to show hidden files in Files and Project panes.
- Allow automatic introduction of docstrings in the Sphhinx format.
- Implicitly create a project when Spyder is launched with a folder path as argument in the command line.
- Activate conda environment prior to kernel start in the IPython console.
- Allow to run again IPython magics in cells.
- Allow to run PyQt applications multiple times.
- Make adjustable the maximum number of recent projects in the Projects menu.
Important fixes:
- Disable code folding and indent guides when files have more than 2000 lines for performance reasons.
- Critical performance improvements to the Editor and Files.
- Several fixes to the autosave mechanism.
- Preserve creation time when saving files.
- Don’t corrupt symlinks when saving files associated to them.
- Improve the code completion experience in the Editor.
- Start kernels in a thread to avoid freezing the entire interface.
- Correctly update the debugging panel in the Editor when debugging in multiple consoles.
- Make the Code Analysis pane to read the nearest pylintrc file, according to the hierarchy defined by Pylint.

In this release we fixed 96 issues and merged 115 pull requests that amount to more than 530 commits. For a full list of fixes, please see our Changelog.

Important note: This version has a serious bug to start kernels on Windows, which will be fixed in 4.1.1, to be released soon.
