I want to thank all the people that make this happening… The list of commits at the end is impressive but it is only for one repository: the one of Pharo and it does not take into account all the subprojects. Thanks you all. S.

Dear Pharo users and dynamic language lovers:
We have released Pharo <https://pharo.org/> version 13!
What is Pharo?
Pharo is a pure object-oriented programming language and a powerful environment focused on simplicity and immediate feedback.

Simple & powerful language: No constructors, no types declaration, no interfaces, no primitive types. Yet a powerful and elegant language with a full syntax fitting in one postcard! Pharo is objects and messages all the way down. Live, immersive environment: Immediate feedback at any moment of your development: Developing, testing, debugging. Even in production environments, you will never be stuck in compiling and deploying steps again! Amazing debugging experience: Pharo environment includes a debugger unlike anything you’ve seen before. It allows you to step through code, restart the execution of methods, create methods on the fly, and much more! Pharo is yours: Pharo is made by an incredible community, with more than 100 contributors for the last revision of the platform and hundreds of people constantly contributing with frameworks and libraries. Fully open-source: Pharo full stack is released under MIT <https://opensource.org/licenses/MIT> License and available on GitHub <https://github.com/pharo-project/pharo> … more on the Pharo Features page <http://www.pharo.org/features>. In this iteration of Pharo, we continue working on our objectives of improvement, clean-up and modularization. Also, we included a number of usability and speed improvements. A detailed list of changes and improvements is available in our Changelog <https://github.com/pharo-project/pharo-changelogs/tree/master/weekly> (weekly based)
