Hello everyone,
Happy New Year to all of you 
As every year, I have written a year-end article to summarize all the new features, as well as my goals for 2021.
Article to read on the blog, feel free to comment here if you have any feedback 
Hello @pierre-gilles
The year 2020 
ended in style with this official v4 version. Looking forward to the 2021 developments. Thanks to you and all the developers. 
Being a complete beginner in computer science, I canât help the community much, but in any case, with the forum and the internet, I learn day by day and it fascinates me.
See you soon
