[Daniel Althviz Moré]

Hi all,

On the behalf of the Spyder Project Contributors, I'm pleased to announce that Spyder 5.4.0 has been released and is available for Windows, GNU/Linux and MacOS X: https://github.com/spyder-ide/spyder/releases

This release comes nine weeks and four days after version 5.3.3 and it contains the following new features and important fixes:

• New UI/UX elements to update standalone installers with options to download and install a new version if available.
• New experimental conda-based standalone installers for MacOS and Linux (available on the GitHub release page with the EXPERIMENTAL- prefix).
• Now the Code Analysis/Pylint plugin uses the current custom interpreter/environment if set.
• Option to show user environment variables extended to all operative systems (previously available only for Windows).
• Improve Outline Explorer plugin performance and fix updating process when it becomes visible.
• Improvements to colors on the dependencies dialog and IPython console.
• Fix IPython console issues on the Matplotlib TkInter backend with debugging and an increase of CPU and memory usage while in an idle state.
• Fix IPython console memory leak when using the Matplotlib Qt backend.
• Fix IPython console input() issue on MacOS.
• Fix IPython console kernel error regarding environment path as unexpected argument.
• Fix Spyder 3 icon theme load on Windows with untrusted fonts security restrictions.
• Fix the Autoformat files on save functionality to not hang with non-Python files.
• Some fixes for cell execution on Python 3.11.
• Some fixes to shortcuts (Switch to Editor, Find Next, Find Previous).
• Some fixes to improve compatibility with PySide2.
• Some fixes to prevent blurry SVG icons.

In this release we fixed 48 issues and merged 59 pull requests that amount to more than 292 commits. For a full list of fixes, please see our Changelog.

Regarding the new experimental conda-based installers, with this release we started building them for MacOS (arm64 and x86_64 architectures) and Linux (so a new way to install Spyder on Linux is available!). You can find them on the Spyder 5.4.0 release page in the assets section (the .pkg files for MacOS and a .sh file for Linux with the prefix EXPERIMENTAL). Any feedback regarding this new way of installation is greatly appreciated.

Don't forget to follow Spyder updates/news on the project's website.

Last, but not least, we welcome any contribution that helps making Spyder an efficient scientific development and computing environment. Join us to help creating your favorite environment!

Enjoy!

Daniel
