Dear World,

Pharo 4.0 (http://www.pharo.org) is here.

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

Many things have changed in Pharo. Here are some highlights:
- Inspector/Playground/Spotter are new moldable development tools for inspecting, coding and searching objects.
- Slots model instance variables as first class entities and enable meta-programming on this level.
- ShoreLine reporter introduces a way to report system errors and collect statistics, that we will use for future improvements 
- Dark theme.

These are just the more prominent highlights, but the details are just as important. We have closed 1697 issues in Pharo 4. Take a moment to go through a more detailed recount of the progress:


Pharo is improving on many fronts, but one of the most prominent changes is the addition of moldable tools for inspection and search. These tools provide extension mechanisms that allow every object to define ways in which it can be understood effectively. To provide an idea of the impact of the already existing extensions, the map below shows the Pharo classes grouped in packages, highlighting in red those parts of the system that have at least one such custom view coming with the main distribution. The spread of these extensions shows that moldability is powerful mechanism that can be used in many contexts.

Remember that Pharo is your platform. We thank all the contributors of this release:
