We have closely followed +the development of Qt5 and greatly appreciate the direction the Qt developers +are heading to. Now that Qt5 has reached a stable state, the time is right for +Genode to make the switch from Qt4 to Qt5. With the fresh port of Qt version +5.1 to Genode, Qt becomes available on the entirety of kernels supported by the +framework. + +Component-based systems use to pose the difficulty of getting a holistic view +on the system. The more complex the system scenarios become, the more +inter-component communication takes place. Finding performance bottlenecks in +such kinds of de-componentized systems tends to be much more challenging than +in the world of monolithic systems. To overcome this challenge, the new +version comes with tracing support deeply built into the framework. This +facility is able to capture the interactions of Genode components between each +other in a light-weight fashion with almost no side effects. + +As the third major addition, version 13.08 comes with substantial support for +multi-processor systems, in particular for using Genode with the NOVA kernel. +Within the NOVA developer community, this controversial topic has been +discussed for several years. It seemed like NOVA's multi-processor model was +inherently contradicting with the design of the Genode API. However, we have +finally found a fairly elegant solution that makes multiple CPUs seamlessly +available for Genode users on NOVA. + +Besides these highlights, the release comes with new SATA 3.0 and +power-management drivers for the Samsung Exynos-5 SoC, updates the Fiasco.OC +kernel and L4Linux, and introduces measures for verifying the integrity of +downloaded 3rd-party source codes. + +Those and many more topics are presented in detail in the +[http:/documentation/release-notes/13.08 - release documentation of version 13.08...] + + Genode OS Framework release 13.05 | 2013-05-30 ##############################################
