Dear Pharo users and dynamic language lovers:
We have released Pharo version 12!
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

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 complete list of changes and improvements is available in our Changelog
Some highlights of this amazing version:
Highlights
New breakpoint system
The debug point system is a breakpoint model that supersedes the previous implementation of breakpoints and watchpoints. They are configurable, composable, and extensible. The traditional breakpoints remain available, including conditional breakpoints, one-time breakpoints, and object-centric breakpoints. Additionally, there are new types of breakpoints, such as chained-breakpoints, which condition the activation of certain breakpoints on the triggering of others (e.g., breakpoint B only activates if breakpoint A is hit first). Debug points also feature a dedicated browser and integration options.
Tools
Scalable fluid class syntax is now the default onePreparing the introduction of the Bloc graphic system by migrating more tools to Spec2 widgetsSpec2 UI framework enhancements to support GTK 4Leaner version of the Metacello package managerMore robust and strict mode for FFI
