Pharo 5.0 Released!

Dear World,

The time has come for Pharo 5.0!

Pharo is a pure object-oriented programming language and a powerful environment, focused on simplicity and immediate feedback.

This is our most significant release yet. Here are some highlights:

  • The PharoVM is now based on Spur, the new memory management, and it brings with it a 35% speedup!
  • A new unified foreign function interface (UFFI) replaced NativeBoost to provide a strong Spur-compatible framework for interfacing with the outside world.
  • The Glamorous Toolkit now includes the GTDebugger to offer a moldable infrastructure that allows the developer to customise the debugger deeply.
  • The underlying Reflectivity mechanism has reached maturity with multiple pieces coming together to empower developers to instrument their own systems. For example, we now have breakpoints implemented as just a simple extension of this mechanism.
  • QualityAssistant is now part of the image to provide live feedback during development.

These are just the more prominent highlights, but the details are just as important. We have closed 2446 issues in Pharo 5.0. Take a moment to go through a more detailed recount of the progress.

While the technical improvements are significant, just think of getting 30% faster out-of-the-box, still the most impressive fact is that the new code that got in the main Pharo 5.0 image was contributed by 100 people. Together we have touched 43% of the classes, and 20% of the methods. The following visualisation rendered with Roassal in Pharo 5.0 is dedicated to this effort. The picture shows the touched classes and packages in gray, the authors and the links to the changed classes in red, and, using an automatically generated visual id, you can spot authors that have worked on similar projects.

Pharo is more than code. It is an exciting project involving energetic people. We thank all the contributors of this release:
