Pharo 13 Released!

Dear Pharo users and dynamic language lovers:

We have released Pharo 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 License and available on GitHub
