Spyder 3.0 has been a huge success (being downloaded more than 2.5
million times in 2018 alone!) and we hope 4.0 will be as successful. For
that we fixed 502 bugs, merged 741 pull requests from about 60 authors
and added more than 5000 commits between these two releases.
Don’t forget to follow Spyder updates/news on the project’s website
<https://www.spyder-ide.org>.
Last, but not least, we welcome any contribution that helps making
Spyder an efficient scientific development/computing environment. Join
us to help creating your favorite environment!
Enjoy!
Carlos
