Pharo3 is close to being released. But development is not standing still: Soon the development of Pharo4 will start. As with Pharo3, the plan is to integrate changes for 10 months with a 2 month bug fix period and a release within one year. This talk will give an overview of what people are working on for Pharo4. Topics will be - Boostrap from Source - Minimal and virtual images - towards one image file - better model for saving changes - VM level work (e.g. type feedback optimisation)
