Self Mallard 4.5.0 released | Self. It's still alive. It's still one of the coolest systems to emerge from Smalltalk - very exotic, very different. From some aspects, systems can still learn today - the implementation of prototypical inheritance in the graphical development environment is really cool and still looks modern even today. The GUI framework itself has already found its way into Squeak some time ago, but outside the Squeak+Self world, hardly anyone knows it. Which is a shame. And the compiler is still one of the better ones in the field of bytecode languages. Especially when you compare how JavaScript presents itself today and what Self has been able to do for ages, you can get quite sad.
